Washing Machine Running Cost Calculator

Almost all of a washing machine's electricity goes into heating the water, not turning the drum. That is why a 60 °C cotton wash can cost three times as much as the same load at 30 °C. Use the calculator to price your own cycle mix per load, per week and per year.

How this calculator works

Energy per load (kWh) = Average watts ÷ 1000 × Cycle length in hours

Cost per load = Energy per load × Tariff

Annual cost = Cost per load × Loads per week × 52

Set 'days' to the number of loads per month rather than calendar days, and 'hours' to the cycle length. The presets already reflect the average draw across a whole cycle, including the heating phase and the spin.

Worked example

Four loads a week at 40 °C, 700 W average over a 1.5-hour cycle: 0.7 × 1.5 = 1.05 kWh per load. At £0.247 that is £0.26 a load, £54 a year. Switch the same loads to 30 °C (0.75 kWh) and the annual cost falls to about £39 — a £15 saving for changing one dial setting.

Energy per wash by temperature

Cycle	Energy per load	Relative cost
Cold wash (20 °C)	0.20 – 0.35 kWh	1.0×
30 °C cotton	0.55 – 0.80 kWh	≈ 2.5×
40 °C cotton	0.90 – 1.20 kWh	≈ 3.7×
60 °C cotton	1.60 – 2.20 kWh	≈ 6.5×
90 °C boil wash	2.50 – 3.20 kWh	≈ 10×
Quick 15 min	0.30 – 0.50 kWh	≈ 1.5×
Eco cycle (long, low temp)	0.45 – 0.70 kWh	≈ 2.0×

Lower cost per load

Default to 30 °C. Modern detergents are formulated for low temperatures and handle everyday soiling perfectly well.
Run full loads. A half-empty drum uses nearly the same water and heat as a full one.
Use the eco cycle even though it is longer. It saves energy by washing longer at a lower temperature — time is not what costs money, heat is.
Spin faster before drying. A 1,400 rpm spin removes far more water than 800 rpm and cuts expensive dryer time.
Skip pre-wash unless clothes are genuinely dirty. It can add 20–30% to cycle energy.
Shift to off-peak hours if you have a time-of-use tariff. Delay-start timers exist for exactly this.

Frequently asked questions

How much does it cost to run a washing machine per load?

A typical 40 °C load using about 1 kWh costs roughly $0.17 in the US, £0.25 in the UK, ₹8 in India and A$0.33 in Australia. A 60 °C load roughly doubles that, and a cold wash costs about a third.

Does washing at 30 degrees really save money?

Yes, and it is one of the largest easy savings in the house. Heating water dominates the cycle, so dropping from 40 °C to 30 °C typically cuts energy per load by around 30–40%. Across four loads a week that is a meaningful annual saving with no equipment change.

Why is the eco cycle longer if it uses less energy?

Because it substitutes time for temperature. A longer soak at a lower temperature achieves the same cleaning while the heating element does much less work, and the element is what consumes almost all the electricity.

How much electricity does a washing machine use per year?

Four loads a week at about 1 kWh each is roughly 208 kWh a year. Households running eight hot loads a week can exceed 600 kWh. Enter your own load count above to get your figure.

Is a washer-dryer more expensive to run?

The washing part is the same, but the drying part is where the cost sits — condenser drying in a washer-dryer typically uses 2–4 kWh per load, often more than the wash itself. Our tumble dryer calculator breaks that out separately.

Dishwasher Running Cost Calculator

Most of a dishwasher's electricity goes on heating water, not on turning the spray arms. That is why the programme you choose matters far more than the machine you own — an eco cycle can use half the energy of an intensive one on the same load.

How this calculator works

Units per cycle = Watts ÷ 1000 × Cycle hours

Monthly cost = Units per cycle × Cycles per month × Tariff

Annual cost = Cost per cycle × Cycles per year

Dishwashers do not draw their rated power for the whole cycle. The heating element runs hard during the wash and dry phases and barely at all in between, so a '1,800 W' machine averages far less across a two-hour eco programme. Enter the cycle length in the hours field and treat the wattage as an average rather than a peak. If your machine displays energy use per cycle in kWh, that figure is more accurate than any wattage estimate.

Worked example

A standard 60°C cycle averaging 1,500 W over 1.5 hours uses 2.25 kWh — about 38¢ at 17¢/kWh. Run five times a week that is roughly $100 a year. Switching to an eco programme at 1,000 W over 2.5 hours uses 2.5 kWh but heats less water overall, and on most machines lands 20–30% lower on the meter.

Typical energy use by programme

Programme	Typical energy	Cost at 17¢/kWh	Notes
Eco 50°C	0.9 – 1.1 kWh	$0.15 – $0.19	Longest cycle, lowest energy
Standard 60°C	1.3 – 1.6 kWh	$0.22 – $0.27	Everyday default
Intensive 70°C	1.8 – 2.2 kWh	$0.31 – $0.37	Pans and baked-on food
Quick wash	0.8 – 1.2 kWh	$0.14 – $0.20	Fast but not efficient
Half load	0.7 – 0.9 kWh	$0.12 – $0.15	Rarely worth it vs full eco

Cutting dishwasher costs

Use eco, and ignore how long it takes. Eco cycles save energy by washing longer at a lower temperature. The extra time costs nothing.
Run it full. A half-load setting rarely halves the energy — it is usually around 70% of a full cycle for half the dishes.
Skip the heated dry. Opening the door at the end and letting dishes air-dry removes one of the biggest single loads in the cycle.
Do not pre-rinse under a hot tap. You are paying to heat water twice. Scrape instead; modern detergents need some soil to work against.
Check your hot fill option. Some machines can take a hot feed. If your water is heated by gas or solar, that can be considerably cheaper than electric heating inside the machine.
Clean the filter monthly. A blocked filter makes the machine work longer to reach the same result.

Frequently asked questions

How much electricity does a dishwasher use per cycle?

Typically 1.0 to 2.0 kWh depending on the programme and the machine's age. Eco cycles sit at the bottom of that range, intensive cycles at the top. Modern A-rated machines are usually under 1 kWh on eco.

Is a dishwasher cheaper than washing by hand?

Usually yes, provided you run it full and on eco. A full eco cycle uses around 10 litres of water; washing the same load by hand under a running tap commonly uses three to five times that, and you pay to heat all of it.

Does the eco programme really save money?

Yes, typically 20–30% against a standard cycle. It works by washing longer at a lower temperature, and because heating water is the dominant cost, a lower temperature beats a shorter run time.

Should I use a quick wash to save energy?

No. Quick washes save time, not energy — they compensate for the short duration with a higher temperature and more water. Eco is almost always the cheapest option on the dial.

How much does a dishwasher add to my annual bill?

Run five times a week at around 1.5 kWh a cycle, roughly 390 kWh a year — about $66 at 17¢/kWh or £96 at 25p/kWh. Heavy users running daily on intensive can easily double that.

Water Heater (Geyser) Running Cost Calculator

Water heating is usually the second-largest electricity load in a home after heating or cooling. This geyser and water heater cost calculator converts your element wattage and daily runtime into units, then prices them at your tariff so you can see the monthly damage.

How this calculator works

Units per hour = Element watts ÷ 1000

Daily cost = Units per hour × Hours the element is actually heating × Tariff

Energy to heat water (kWh) = Litres × Temperature rise in °C × 0.00116

The third formula is the useful one for storage geysers: heating 15 litres from 25 °C to 60 °C needs 15 × 35 × 0.00116 ≈ 0.61 kWh, which a 2,000 W element delivers in about 18 minutes. Standby losses then add roughly 0.5–1.5 kWh a day if the geyser stays switched on.

Worked example

A 15 L geyser with a 2,000 W element, heating twice a day for 20 minutes each time, runs 0.67 hours a day: 2 × 0.67 = 1.34 kWh a day. At ₹8/unit that is about ₹11 a day and ₹322 a month. Leave the same geyser switched on around the clock and standby reheating can push it past ₹700 a month.

Energy needed for common hot-water jobs

Task	Litres of hot water	Approx. energy
Hand wash	3 L	0.12 kWh
Kitchen sink of dishes	12 L	0.49 kWh
Short shower (5 min, efficient head)	35 L	1.42 kWh
Average shower (8 min)	65 L	2.64 kWh
Long shower (15 min, power shower)	150 L	6.09 kWh
Full bath	120 L	4.87 kWh
Full 100 L tank from cold	100 L	4.06 kWh

Cutting hot water costs

Switch the geyser on 20 minutes before you need it. A timer or smart plug removes the temptation to leave it on all day.
Set the thermostat to 55–60 °C. Hotter than that wastes energy on standby losses and risks scalding, cooler than 55 °C raises legionella risk in stored water.
Insulate the tank and the first two metres of pipe. A geyser blanket typically pays for itself within a season.
Fit a low-flow shower head. Cutting flow from 12 L/min to 8 L/min removes a third of the energy from every shower.
Fix dripping hot taps. A drip a second wastes roughly 1,300 litres a year, all of it heated.
Consider a heat pump water heater. At roughly a third of the electricity of a resistive element, it is the biggest single saving available on hot water.

Frequently asked questions

How many units does a geyser consume per hour?

A geyser uses its element wattage divided by 1,000 units per hour while the element is on. A 2,000 W geyser uses 2 units per hour, a 3,000 W instant heater uses 3. The key point is that a storage geyser's element is not on continuously — it only heats until the thermostat is satisfied, then cycles occasionally to cover standby loss.

Is it cheaper to leave the geyser on all day or switch it on when needed?

Switching it on when needed is cheaper in almost every case. A tank that stays hot for 24 hours loses heat continuously through its walls and must reheat repeatedly. Households that move to a timer typically cut water-heating energy by 15–30% with no change in comfort.

How much electricity does a shower use?

An 8-minute shower using about 65 litres of hot water needs roughly 2.6 kWh of electricity for the heating alone. At average tariffs that is about $0.45 in the US, £0.65 in the UK or ₹21 in India — before you add pump or instant-heater losses.

Instant water heater vs storage geyser — which costs less?

An instant heater has no standby loss and only heats what you draw, which suits short, occasional use. A storage geyser is more comfortable for back-to-back showers and can run on cheap off-peak electricity or solar surplus. Compare them by running both configurations through the calculator with your own usage pattern.

What temperature should I set my water heater to?

55–60 °C is the usual recommendation: hot enough to suppress bacterial growth in the tank, cool enough to limit standby loss and scald risk. Every 10 °C you drop the setpoint typically saves around 3–5% of water heating energy.

How electricity is billed in the UAE

UAE electricity is billed on a slab structure that also depends on the customer category. In Dubai, DEWA charges expatriate residential customers in four consumption bands rising from 23 to 38 fils per kWh, with UAE nationals on a separate subsidised scale. Bills also carry a fuel surcharge, meter charges and municipality housing fees. Many apartments in newer developments are additionally connected to district cooling, which is billed entirely separately by providers such as Empower and typically includes a fixed capacity charge that you pay even when the apartment is empty.

When water heater / geyser costs peak in the UAE

Costs peak from May through September, when cooling runs almost continuously and consumption commonly moves into the highest tariff slab. The difference between a February bill and an August bill is often threefold.

Local tip. If your building is on district cooling, the fixed capacity charge is unavoidable and unrelated to how much you cool the apartment — so judge any efficiency measure against the consumption portion only. Setting the thermostat to 24°C rather than 20°C is the largest single lever most residents have.

How electricity is billed in Australia

Australian retailers charge a usage rate of roughly 33c per kWh plus a daily supply charge of around $1.00 to $1.30. Many homes are on time-of-use tariffs with distinct peak, shoulder and off-peak windows, and a separate cheaper 'controlled load' circuit is common for electric hot water and pool pumps. Households with rooftop solar also receive a feed-in tariff for exported energy, though feed-in rates have fallen sharply and are now typically well below the usage rate — which makes self-consumption far more valuable than export.

When water heater / geyser costs peak in Australia

Summer, from December to February, drives the highest bills in most of the country through air-conditioning load. Victoria, Tasmania and the ACT see a second winter peak where electric heating is common.

Local tip. If you have solar, using power while the sun is up is worth roughly three times as much as exporting it. Running the dishwasher, washing machine and pool pump in the middle of the day is the single highest-value habit change available to an Australian solar household.

How electricity is billed in Canada

Canadian electricity is comparatively cheap, averaging around 19 cents per kWh, but the structure differs sharply by province. Quebec, Manitoba and British Columbia benefit from abundant hydro and sit well below the national average. Ontario uses mandatory time-of-use pricing with on-peak, mid-peak and off-peak windows that shift between summer and winter schedules, and also offers an optional tiered plan. Most provinces add a fixed monthly service charge on top of the per-kWh energy charge.

When water heater / geyser costs peak in Canada

Winter dominates in most of Canada, with December through February bringing the highest bills wherever heating is electric. Homes on natural gas heat see a much flatter annual profile, with a modest summer bump from air conditioning.

Local tip. In Ontario, shifting laundry and dishwashing to after 7pm on weekdays — or any time at weekends, when the entire day is off-peak — moves that consumption to roughly half the on-peak rate at no cost to you.

How electricity is billed in the Eurozone

Eurozone electricity averages around €0.285 per kWh but the variation between member states is large — Germany and Denmark sit well above the average while France, helped by its nuclear fleet, sits below it. Bills typically combine an energy charge, a network or grid fee, and a substantial tax and levy component that in several countries exceeds the cost of the energy itself. Many suppliers offer day/night or dynamic hourly pricing, and dynamic tariffs linked to the wholesale spot market have become widely available.

When water heater / geyser costs peak in the Eurozone

Winter drives the peak in most of the eurozone, particularly in countries with significant electric heating. Southern member states such as Spain, Italy and Greece increasingly see a comparable summer peak from air conditioning.

Local tip. Check how much of your bill is energy and how much is network fees and taxes. In several member states the non-energy component is more than half the total, which means using less electricity saves less than the headline rate suggests.

How this calculator works

Units per hour = Element watts ÷ 1000

Daily cost = Units per hour × Hours the element is actually heating × Tariff

Energy to heat water (kWh) = Litres × Temperature rise in °C × 0.00116

The third formula is the useful one for storage geysers: heating 15 litres from 25 °C to 60 °C needs 15 × 35 × 0.00116 ≈ 0.61 kWh, which a 2,000 W element delivers in about 18 minutes. Standby losses then add roughly 0.5–1.5 kWh a day if the geyser stays switched on.

What is outside this cost estimate?

Product maintenance, repairs, financing and a guaranteed performance level are not included. Where a grid-carbon estimate appears, it uses the illustrative factor 0.251 kg CO₂/kWh, not a live local measurement or full lifecycle calculation. No petrol-versus-EV emissions comparison is inferred from fuel litres.

Water Heater / Geyser costs in the Eurozone — FAQ

How many units does a geyser consume per hour?

A geyser uses its element wattage divided by 1,000 units per hour while the element is on. A 2,000 W geyser uses 2 units per hour, a 3,000 W instant heater uses 3. The key point is that a storage geyser's element is not on continuously — it only heats until the thermostat is satisfied, then cycles occasionally to cover standby loss.

Is it cheaper to leave the geyser on all day or switch it on when needed?

Switching it on when needed is cheaper in almost every case. A tank that stays hot for 24 hours loses heat continuously through its walls and must reheat repeatedly. Households that move to a timer typically cut water-heating energy by 15–30% with no change in comfort.

How much electricity does a shower use?

An 8-minute shower using about 65 litres of hot water needs roughly 2.6 kWh of electricity for the heating alone. At average tariffs that is about $0.45 in the US, £0.65 in the UK or ₹21 in India — before you add pump or instant-heater losses.

How electricity is billed in India

Indian domestic tariffs are almost always slab-based, and this is what makes estimating a bill genuinely difficult. The first 100 units might cost ₹4–5, the next 200 units ₹6–7, and consumption beyond 400 units ₹8–9 or more. Crucially, in many states crossing a slab boundary re-prices your entire consumption at the higher rate rather than just the excess units. On top of the energy charge sit a fixed charge based on sanctioned load, an electricity duty, and often a fuel surcharge that varies month to month. Rates differ substantially between state discoms, so a Maharashtra bill and a Delhi bill for identical usage will differ.

When water heater / geyser costs peak in India

Costs peak from April to June across most of the country, when air conditioners, coolers and fans run hardest. This is also exactly when households are most likely to cross into a higher tariff slab, which is why summer bills often rise faster than summer consumption does.

Local tip. Find out where your next slab boundary sits and how close you are to it. Because many discoms re-price all units at the higher rate once you cross, cutting consumption by twenty or thirty units can occasionally save several hundred rupees — far more than the units themselves are worth.

How electricity is billed in the United Kingdom

An electricity bill separates variable kWh charges from a fixed standing charge. For the July-September 2026 period the Ofgem Great Britain Direct Debit standard-variable reference is 26.11p/kWh plus 57.19p/day, including 5% VAT. It applies as an average reference across England, Scotland and Wales, not to every UK household or Northern Ireland. Your own supplier, region, payment method or fixed-rate plan can differ. With a time-of-use plan, price each charging or appliance session using the rate in that window.

When water heater / geyser costs peak in the United Kingdom

UK electricity costs rise through the winter, peaking in December and January when lighting hours are longest and any electric heating is working hardest. Air conditioning is rare enough that summer is generally the cheapest quarter.

Local tip. Use your bill’s variable price per kWh when estimating an extra appliance. Do not add a standing charge to each device, or add VAT again if it is included. An off-peak EV rate can come with different daytime pricing; compare the whole household bill.

How electricity is billed in the United States

Most US households are billed a flat per-kWh rate plus a fixed monthly customer charge of roughly $8 to $15. Rates vary enormously by state — Hawaii runs above 50¢/kWh while Idaho and Utah sit near 12–13¢. Many utilities now offer optional time-of-use plans where afternoon and early-evening power costs substantially more than overnight power, and a growing number of states are making time-of-use the default for new connections. Some utilities also apply seasonal rates, with summer kWh priced higher than winter to reflect air-conditioning demand.

When water heater / geyser costs peak in the United States

Costs peak in July and August across most of the country, when cooling load is highest and many utilities switch to summer pricing at the same time. In the Northeast and Upper Midwest a second, smaller peak appears in January and February wherever homes use electric resistance heating or heat pumps.

Local tip. Check whether your utility offers a time-of-use plan before you assume a flat rate. If you can move laundry, dishwashing and EV charging to overnight hours, the off-peak rate is frequently less than half the on-peak rate and the switch costs nothing.

How electricity is billed in South Africa

Most South African households buy electricity on a prepaid meter, and Eskom's Homepower and municipal prepaid tariffs are block-based: the first block of units each month is cheapest, and the rate steps up as you buy more within the same calendar month. Because the blocks reset monthly, buying a large amount of electricity in one go pushes you into the higher blocks immediately. Postpaid customers additionally pay a fixed basic charge. Tariffs have risen far faster than general inflation for over a decade, and load shedding schedules add a further complication by concentrating consumption into fewer hours.

When water heater / geyser costs peak in South Africa

Winter, from June to August, brings the highest bills as geysers work harder against colder inlet water and electric heating comes on. Highveld winters in particular drive a sharp seasonal increase.

Local tip. The geyser is typically 30 to 40 percent of a South African household's electricity use. Fitting a geyser blanket and a timer, and dropping the thermostat to 55°C, is the highest-return efficiency spend available — usually recovered within a few months.

Electric Kettle Running Cost Calculator

A kettle draws more power than almost anything else in the kitchen — 3,000 watts is common — but only for two or three minutes. The real question is not what a kettle costs to run, but how much you waste by boiling more water than you need.

How this calculator works

Units per boil = Watts ÷ 1000 × Boil time in hours

Daily cost = Units per boil × Boils per day × Tariff

One cup takes about 45 seconds; a full kettle takes about 3 minutes

Boil time is the variable that matters, and it scales almost exactly with the amount of water. A 3,000 W kettle boiling one cup takes roughly 45 seconds (0.0125 hours); the same kettle full takes about three minutes (0.05 hours). Enter the hours field as a decimal — 45 seconds is 0.0125, two minutes is 0.033, three minutes is 0.05. The wattage barely affects total energy for a given volume: a faster kettle uses the same energy in less time.

Worked example

A 3,000 W kettle boiling for 3 minutes uses 0.15 kWh — about 2.6¢ at 17¢/kWh. Boiled ten times a day that is $9.30 a year. But if you only need one cup and boil a full kettle each time, you are paying roughly four times what you need to — around $28 a year wasted in a heavy-tea household.

Cost per boil by volume

Amount	Boil time (3 kW)	Energy	Cost at 17¢/kWh
1 cup (250 ml)	45 sec	0.038 kWh	$0.006
2 cups (500 ml)	1.5 min	0.075 kWh	$0.013
4 cups (1 L)	2.5 min	0.125 kWh	$0.021
Full kettle (1.7 L)	3 min	0.150 kWh	$0.026
Full kettle, 10×/day	30 min	1.5 kWh	$0.26/day

Small habits that add up

Fill only what you need. This is the entire saving. Boiling one cup instead of a full kettle uses a quarter of the energy for the same cup of tea.
Descale it. Limescale on the element insulates it, so the kettle runs longer for the same boil. In a hard-water area this is a real and growing cost.
A faster kettle does not use more energy. A 3 kW kettle and a 2 kW kettle use almost the same energy for the same water — one just gets there sooner.
Do not reboil. Water that has cooled from boiling to 80°C only needs a fraction of the energy to get back, but most people reboil the whole kettle.
An instant hot water tap is not automatically cheaper. It avoids overfilling but keeps a tank hot around the clock. For light users the kettle wins.

Frequently asked questions

How much does it cost to boil a kettle?

About 2.6¢ for a full 1.7 L kettle at 17¢/kWh, or roughly 0.6¢ for a single cup. In the UK at 25p/kWh a full kettle is around 3.8p and a single cup under a penny.

Does a higher wattage kettle cost more to run?

No, essentially the same. Energy is power multiplied by time, and a more powerful kettle boils the same water proportionally faster. A 3 kW kettle simply gets there quicker than a 2 kW one.

How much does overfilling a kettle waste?

Boiling a full kettle for one cup uses roughly four times the necessary energy. For a household boiling ten times a day, that is on the order of $20 to $30 a year thrown away.

Is a kettle cheaper than boiling water on the hob?

An electric kettle is more efficient than an electric hob because the element is immersed in the water rather than heating a pan from below. Gas can be cheaper per unit of energy, but is slower and loses more heat around the pan.

Does descaling save electricity?

Yes. Limescale acts as insulation on the heating element, so a scaled kettle takes longer to boil the same water. In hard-water areas descaling every month or two is worth doing.

Water Pump Running Cost Calculator

A water pump is a short-duration, high-power load that most households never think about — until they see a bill after a dry spell. A 1 HP pump filling a tank twice a day can quietly add more to the bill than a refrigerator.

Monthly cost = Units per day × Days × Tariff

1 HP ≈ 746 W of output; input draw is higher due to motor efficiency

Horsepower describes the motor's output, not what it draws from the supply. A 1 HP motor delivers 746 W of mechanical power but typically draws 850 to 1,000 W at the meter, because motor efficiency is usually 75 to 88%. If you want an accurate figure, use the input wattage or the current rating from the nameplate rather than converting from HP. Pumps also draw a large starting surge, which does not affect the energy bill much but does matter for cable and breaker sizing.

Worked example

A 1 HP pump at 750 W running 1 hour a day uses 0.75 kWh — about ₹6 at ₹8/kWh, or ₹180 a month. Run twice a day in summer, that doubles to ₹360. A 3 HP borewell pump running the same hours costs roughly ₹1,056 a month.

Water pump running cost

Pump	Approx. draw	Units per hour	Monthly at 1 h/day
0.5 HP booster	370 W	0.37 kWh	₹89
0.75 HP	550 W	0.55 kWh	₹132
1 HP	750 W	0.75 kWh	₹180
1.5 HP	1,100 W	1.10 kWh	₹264
2 HP submersible	1,500 W	1.50 kWh	₹360
3 HP borewell	2,200 W	2.20 kWh	₹528

Reducing pumping cost

Fit a tank float switch. Manual pumping means overrunning, and an overflowing tank is pure wasted electricity plus wasted water.
Fix leaks first. A dripping overhead tank or a leaking foot valve makes the pump cycle far more often than it needs to.
Do not oversize the pump. A pump much larger than the head and flow require runs inefficiently and costs more per litre delivered.
Check the foot valve annually. A failing foot valve lets the column drain back, so the pump has to re-prime and lift the same water twice.
Keep suction pipe runs short and straight. Every bend and every metre of lift adds to the work the motor has to do.

Frequently asked questions

How much electricity does a 1 HP water pump use?

About 0.75 to 1.0 units per hour of running, depending on motor efficiency. Run one hour a day that is roughly 22 to 30 units a month.

How do I convert HP to watts for a pump?

One horsepower is 746 watts of output. Divide by the motor efficiency — typically 0.75 to 0.88 — to get the input draw. A 1 HP motor at 80% efficiency draws about 930 W from the supply.

Why is my water pump bill so high in summer?

Water tables drop, so the pump lifts from deeper and runs longer for the same volume. Usage also rises. The two effects compound, which is why summer pumping costs often double.

Is a submersible pump cheaper to run than a surface pump?

For deep lifts, yes — a submersible pushes water rather than trying to suck it, which is far more efficient beyond about 7 metres. For shallow applications a surface pump is simpler and comparable.

Does a bigger pump fill the tank cheaper?

Not usually. A larger pump fills faster but draws proportionally more, so the energy per litre is similar or worse if the pump is oversized for the head. Right-sizing matters more than speed.

Pool Pump Running Cost Calculator

A pool pump is often the largest single electricity load in a home that has one — bigger than the fridge, sometimes bigger than the air conditioner. It also runs for hours every day, which means the run time you choose is worth more than the pump you buy.

Turnover: aim to circulate the pool volume once per day, not continuously

The key insight for pool pumps is that flow rate and power do not scale linearly. Halving the speed of a variable-speed pump cuts its power draw to roughly one-eighth, while still moving water — it just takes longer. That is why running a variable-speed pump slowly for twelve hours costs dramatically less than running a single-speed pump fast for six, even though both achieve the same turnover.

Worked example

A 1 HP single-speed pump at 1,100 W run 8 hours a day uses 8.8 kWh daily — about $1.50 at 17¢/kWh, or $45 a month. A variable-speed pump doing the same turnover at 300 W over 12 hours uses 3.6 kWh, around $18 a month. Over a season that difference typically pays for the pump upgrade.

Pool pump running cost by type

Pump	Typical draw	Daily units at 8 h	Monthly cost
Variable speed (low)	300 W	2.4 kWh	$12
Variable speed (medium)	600 W	4.8 kWh	$24
Single-speed 0.75 HP	750 W	6.0 kWh	$31
Single-speed 1 HP	1,100 W	8.8 kWh	$45
Single-speed 1.5 HP	1,500 W	12.0 kWh	$61
Single-speed 2 HP	2,000 W	16.0 kWh	$82

Cutting pool pump costs

A variable-speed pump is the single biggest saving available. Because power falls with the cube of speed, running slower for longer uses a fraction of the energy for the same turnover.
You probably run it too long. Most pools need one full turnover a day, not continuous circulation. Cutting from 12 hours to 8 is often invisible in water quality and immediately visible on the bill.
Run it off-peak if you can. In Australia many pools qualify for a controlled-load tariff at roughly half the standard rate.
Clean the skimmer and pump baskets. A restricted intake makes the pump work harder for less flow.
Use a pool cover. It reduces debris and evaporation, which cuts both filtration time and the heating load if the pool is heated.

Frequently asked questions

How much does it cost to run a pool pump?

A 1 HP single-speed pump running 8 hours a day costs roughly $45 a month at 17¢/kWh. A variable-speed pump achieving the same turnover typically costs $15 to $20 a month.

How many hours a day should a pool pump run?

Enough to turn the water over once, which for most domestic pools is 6 to 8 hours with a standard pump. Running longer rarely improves water quality and directly increases cost.

Are variable-speed pool pumps worth the money?

Almost always. Power draw falls with roughly the cube of speed, so running at half speed uses about an eighth of the power. Payback is commonly one to two seasons.

Is it cheaper to run a pool pump at night?

Only if you are on a time-of-use or controlled-load tariff. On a flat rate the time of day makes no difference to cost, though night running is quieter and reduces evaporation.

Does a pool heater cost more than the pump?

Far more. Electric resistance pool heating is one of the most expensive things a household can do. A heat pump pool heater is three to four times cheaper to run for the same heat.

Ovens typically run at a 40–60% duty cycle once preheated, because the thermostat cuts the element in and out. Setting duty cycle to 50% for a one-hour bake is far more accurate than assuming full power throughout.

Worked example

A 2,200 W oven on for one hour at a 50% duty cycle uses 1.1 kWh — about $0.19 at US rates or £0.27 in the UK. The same dish in a 1,500 W air fryer for 25 minutes uses 0.63 kWh at a higher duty cycle, roughly $0.11 — and there is no preheat.

Cooking appliance cost comparison

Appliance	Typical use	Energy used
Electric oven, 1 hour bake	2,200 W @ 50%	1.10 kWh
Air fryer, 25 minutes	1,500 W @ 100%	0.63 kWh
Microwave, 10 minutes	1,400 W	0.23 kWh
Induction hob, 20 minutes	2,000 W @ 70%	0.47 kWh
Slow cooker, 8 hours	220 W	1.76 kWh
Kettle, boil 1.7 L	3,000 W, 3 min	0.15 kWh
Toaster, 3 minutes	1,000 W	0.05 kWh

Cook for less

Skip the preheat for anything that is not baked goods. Roasts and casseroles do not care.
Batch cook. Filling all shelves of a hot oven costs almost the same as using one shelf.
Use the smallest appliance that does the job. Air fryer, microwave or toaster oven beats a full oven for one or two portions almost every time.
Turn the oven off 5–10 minutes early. Residual heat finishes most dishes.
Keep the door shut. Opening it drops the cavity temperature 20–30 °C and forces a full reheat.
Boil only the water you need in the kettle. A full kettle for one cup wastes about 0.1 kWh every time.

Frequently asked questions

How much does it cost to run an electric oven for an hour?

A 2,200 W oven at a realistic 50% duty cycle uses about 1.1 kWh an hour, costing roughly $0.19 in the US, £0.27 in the UK, ₹9 in India and A$0.36 in Australia.

Is an air fryer cheaper than an oven?

For small portions, clearly yes. An air fryer has a tiny cavity that reaches temperature in a minute or two, so a 25-minute cook typically uses around half the energy of the same job in a full oven. For a large family roast the oven wins, because you can fill it.

Does a microwave use less electricity than an oven?

Much less, for anything it can cook. A 10-minute microwave run uses about 0.23 kWh versus roughly 1.1 kWh for an hour of oven time. Microwaves put energy directly into the food rather than heating a large metal box.

What is a slow cooker's running cost?

A slow cooker draws only about 220 W, but runs for eight hours, so it uses roughly 1.76 kWh — similar to a 90-minute oven session. It is efficient per hour, not per meal, so its real advantage is convenience and cheap cuts of meat.

Does the oven use full power the whole time?

No. After preheating, the thermostat cycles the element on and off to hold temperature, so average draw falls to roughly 40–60% of nameplate. That is why the duty-cycle field matters for accurate figures.

TV Running Cost Calculator

Televisions have become dramatically more efficient, but they have also become much larger — and the two effects largely cancel out. A 65-inch OLED can draw four times what a 32-inch LED does, and standby power runs 24 hours a day whether you watch anything or not.

Two things inflate real TV consumption above the label figure. First, picture mode: 'vivid' or 'dynamic' can draw 50% more than 'standard' or 'eco', and HDR content pushes brightness higher again. Second, standby: most sets draw 0.5 to 2 W continuously, and sets with fast-start or voice assistants enabled can draw 10 to 20 W around the clock — which over a year can rival the viewing consumption itself.

Worked example

A 55-inch LED at 100 W watched 5 hours a day uses 0.5 kWh daily — about 8.5¢, or $31 a year at 17¢/kWh. Add a 15 W fast-start standby draw and you add another 131 kWh a year, or $22 — nearly doubling the total for a feature most people never use.

TV power draw by size and type

TV	Typical draw	Annual kWh at 5 h/day	Annual cost
32" LED	45 W	82 kWh	$14
43" LED	65 W	119 kWh	$20
55" LED	100 W	183 kWh	$31
65" LED	130 W	237 kWh	$40
55" OLED	145 W	265 kWh	$45
65" OLED	190 W	347 kWh	$59
75" QLED	210 W	383 kWh	$65

Reducing TV running cost

Turn off fast-start. It keeps the set semi-awake around the clock for a few seconds of boot time. On many sets this is the single largest saving available.
Switch picture mode from vivid to standard. Shop-floor modes are calibrated to look bright under fluorescent lighting, not to be watched at home. The saving is 30–50% with better picture quality.
Enable the ambient light sensor. It dims the panel in a dark room, which saves power and is easier on the eyes.
Use the sleep timer. A TV left on overnight for someone who fell asleep is one of the more common invisible costs in a household.
Do not forget the peripherals. A soundbar, console and set-top box together often draw more on standby than the TV does.

Frequently asked questions

How much electricity does a TV use?

A modern 55-inch LED draws around 100 W while on, using about 0.5 kWh over five hours of viewing. That is roughly 183 kWh a year, or $31 at 17¢/kWh.

Do OLED TVs use more electricity than LED?

Generally yes at the same size — typically 30 to 50% more, because OLED panels drive each pixel individually and run brighter for HDR. The gap narrows with dark content, where OLED switches pixels off entirely.

How much does a TV cost on standby?

A well-behaved set draws 0.5 to 1 W, which is under $1.50 a year. But sets with fast-start, voice assistants or always-on HDMI-CEC can draw 10 to 20 W continuously, which is $15 to $30 a year.

Does screen size affect electricity use?

Substantially. Power scales roughly with screen area, so a 65-inch set uses about 1.7 times what a 50-inch of the same technology does. Going bigger is the largest single factor in TV consumption.

Does turning the brightness down save much?

Yes, more than most people expect. Backlight level is the dominant variable in LED power draw — dropping from vivid to standard commonly cuts consumption by a third or more.

Ten minutes at 1,800 W is 0.3 kWh

Enter the hours field as a decimal fraction of an hour: five minutes is 0.083, ten minutes is 0.17, fifteen minutes is 0.25. Most dryers have heat settings that substantially change the draw — the cool setting runs the motor only and might be 200 W, while full heat is the rated figure. If you use a mix, estimate an average rather than the maximum.

Worked example

An 1,800 W dryer used for 10 minutes uses 0.3 kWh — about 5.1¢ at 17¢/kWh. Used daily that is $1.55 a month or $18.60 a year. Even in a household where several people use one daily, a hair dryer rarely exceeds $60 a year.

Cost per use by duration

Duration	Energy at 1,800 W	Cost at 17¢/kWh	Monthly if daily
5 minutes	0.15 kWh	$0.026	$0.78
10 minutes	0.30 kWh	$0.051	$1.55
15 minutes	0.45 kWh	$0.077	$2.30
20 minutes	0.60 kWh	$0.102	$3.06
30 minutes	0.90 kWh	$0.153	$4.59

Small savings, easy wins

Towel-dry first. Removing surface water cuts drying time by several minutes, which is the only variable that really matters here.
Use the cool shot to finish. The motor alone draws a fraction of the heated setting, and cool air sets the style better anyway.
Do not confuse wattage with cost. A 2,200 W salon dryer that dries hair in six minutes can cost less per use than a 1,400 W dryer that takes twelve.
Clean the rear filter. A clogged intake makes the dryer run hotter and longer, and shortens its life.
Check the breaker if you also run other heat appliances. Two 1,800 W appliances on one circuit is a common cause of nuisance tripping.

Frequently asked questions

How much electricity does a hair dryer use?

A typical 1,800 W dryer uses 0.3 kWh in a ten-minute session — about 5¢ at 17¢/kWh. Despite the high wattage, the short runtime keeps the cost low.

Do hair dryers use a lot of electricity?

They draw a lot of power but consume little energy because they run briefly. Used daily for ten minutes, a hair dryer adds around 110 kWh a year — well under a tenth of what a fridge uses.

Is a higher wattage hair dryer more expensive to run?

Not necessarily. A more powerful dryer finishes faster, and total energy is power multiplied by time. If a 2,200 W dryer halves your drying time against a 1,400 W model, it costs less per use.

How much does a hair dryer add to my monthly bill?

For one person using it daily for ten minutes, roughly $1.50 a month at 17¢/kWh. Even a household of four heavy users is unlikely to exceed $6 a month.

Does the cool setting save electricity?

Yes, substantially. On cool the heating element is off and only the motor runs, which is typically 150 to 250 W against 1,800 W on full heat.

How this calculator works

Energy per cycle (kWh) = Watts ÷ 1000 × Cycle hours

Cost per cycle = Energy per cycle × Tariff

Annual cost = Cost per cycle × Cycles per week × 52

Set 'days' to cycles per month. Heat pump dryers draw far fewer watts but run longer; the calculator handles that correctly because it multiplies watts by actual runtime rather than assuming a fixed cycle.

Worked example

A 2,500 W condenser dryer running 1.5 hours, three times a week: 3.75 kWh per cycle, £0.93 per cycle at £0.247, about £145 a year. A heat pump dryer doing the same job at 800 W over 2.5 hours uses 2 kWh — £0.49 per cycle, £77 a year, cutting the bill nearly in half.

Dryer types compared

Dryer type	Energy per 8 kg load	Cost per cycle at $0.17
Heat pump (A+++)	1.5 – 2.2 kWh	$0.26 – $0.37
Condenser (B/C)	3.5 – 4.5 kWh	$0.60 – $0.77
Vented	3.5 – 5.0 kWh	$0.60 – $0.85
Washer-dryer drying phase	4.0 – 6.0 kWh	$0.68 – $1.02
Air drying on a rack	0 kWh	$0.00

Cheaper drying

Spin at 1,400 rpm or higher first. Every extra litre of water the washer removes is a litre the dryer does not have to boil off.
Clean the lint filter every single cycle. Restricted airflow lengthens cycles more than most people realise.
Dry full loads and sort by fabric weight. Mixing towels with t-shirts means the light items over-dry while the heavy ones set the runtime.
Use auto-sensing instead of timed drying. Timed cycles routinely run 15–20 minutes longer than needed.
Air-dry two loads a week. At typical costs, that alone saves $50–$100 a year with zero investment.
When replacing, buy heat pump. It is the single biggest per-appliance efficiency jump available in a modern home.

Frequently asked questions

How much does a tumble dryer cost per cycle?

A condenser or vented dryer using about 3.75 kWh a cycle costs roughly $0.64 in the US, £0.93 in the UK, ₹30 in India and A$1.24 in Australia. A heat pump dryer typically costs less than half that per load.

Are heat pump tumble dryers worth the extra money?

If you dry more than two loads a week, usually yes. They use roughly 50–60% less electricity per load. On three loads a week the saving is often $70–$120 a year, so a price premium of $300–$400 pays back in three to five years, and faster in high-tariff markets.

How much electricity does a tumble dryer use per year?

Three condenser loads a week at 3.75 kWh is about 585 kWh a year — often 10–15% of a household's total electricity. A heat pump doing the same work uses roughly 310 kWh.

Is it cheaper to use a dryer or a heated airer?

A heated clothes airer typically draws 100–300 W and can dry a load overnight for 1–3 kWh, which is comparable to a heat pump dryer and clearly cheaper than a condenser. It is slower, but in cost terms it usually wins against a vented dryer.

Does a fuller load cost more?

Per load, yes — slightly. Per kilogram of laundry, no: a full load is markedly more efficient because the heat and airflow are shared across more fabric. Always dry full but not overpacked loads.

Average duty	Daily kWh	12-day cost
50%	1.875	AED 6.75
75%	2.812	AED 10.12
100%	3.750	AED 13.50

These examples use stated assumptions, not a product test. Change the form inputs for your own calculation. The annual result assumes the same daily use for 365 days; for a seasonal appliance, multiply daily cost by actual seasonal operating days instead.

How electricity is billed in the UAE

UAE electricity is billed on a slab structure that also depends on the customer category. In Dubai, DEWA charges expatriate residential customers in four consumption bands rising from 23 to 38 fils per kWh, with UAE nationals on a separate subsidised scale. Bills also carry a fuel surcharge, meter charges and municipality housing fees. Many apartments in newer developments are additionally connected to district cooling, which is billed entirely separately by providers such as Empower and typically includes a fixed capacity charge that you pay even when the apartment is empty.

When tumble dryer costs peak in the UAE

Costs peak from May through September, when cooling runs almost continuously and consumption commonly moves into the highest tariff slab. The difference between a February bill and an August bill is often threefold.

Local tip. If your building is on district cooling, the fixed capacity charge is unavoidable and unrelated to how much you cool the apartment — so judge any efficiency measure against the consumption portion only. Setting the thermostat to 24°C rather than 20°C is the largest single lever most residents have.

How this calculator works

Energy per cycle (kWh) = Watts ÷ 1000 × Cycle hours

Cost per cycle = Energy per cycle × Tariff

Annual cost = Cost per cycle × Cycles per week × 52

Set 'days' to cycles per month. Heat pump dryers draw far fewer watts but run longer; the calculator handles that correctly because it multiplies watts by actual runtime rather than assuming a fixed cycle.

What is outside this cost estimate?

Product maintenance, repairs, financing and a guaranteed performance level are not included. Where a grid-carbon estimate appears, it uses the illustrative factor 0.41 kg CO₂/kWh, not a live local measurement or full lifecycle calculation. No petrol-versus-EV emissions comparison is inferred from fuel litres.

Tumble Dryer costs in the UAE — FAQ

How much does a tumble dryer cost per cycle?

A condenser or vented dryer using about 3.75 kWh a cycle costs roughly $0.64 in the US, £0.93 in the UK, ₹30 in India and A$1.24 in Australia. A heat pump dryer typically costs less than half that per load.

Are heat pump tumble dryers worth the extra money?

If you dry more than two loads a week, usually yes. They use roughly 50–60% less electricity per load. On three loads a week the saving is often $70–$120 a year, so a price premium of $300–$400 pays back in three to five years, and faster in high-tariff markets.

How much electricity does a tumble dryer use per year?

Three condenser loads a week at 3.75 kWh is about 585 kWh a year — often 10–15% of a household's total electricity. A heat pump doing the same work uses roughly 310 kWh.

Is the UAE starting rate a live quote?

No. The tariff note names the scope and source of the starting rate where available; otherwise it is explicitly illustrative. Replace it with your own variable electricity rate. Keep fixed connection charges separate.

How electricity is billed in Australia

Australian retailers charge a usage rate of roughly 33c per kWh plus a daily supply charge of around $1.00 to $1.30. Many homes are on time-of-use tariffs with distinct peak, shoulder and off-peak windows, and a separate cheaper 'controlled load' circuit is common for electric hot water and pool pumps. Households with rooftop solar also receive a feed-in tariff for exported energy, though feed-in rates have fallen sharply and are now typically well below the usage rate — which makes self-consumption far more valuable than export.

When tumble dryer costs peak in Australia

Summer, from December to February, drives the highest bills in most of the country through air-conditioning load. Victoria, Tasmania and the ACT see a second winter peak where electric heating is common.

Local tip. If you have solar, using power while the sun is up is worth roughly three times as much as exporting it. Running the dishwasher, washing machine and pool pump in the middle of the day is the single highest-value habit change available to an Australian solar household.

How electricity is billed in Canada

Canadian electricity is comparatively cheap, averaging around 19 cents per kWh, but the structure differs sharply by province. Quebec, Manitoba and British Columbia benefit from abundant hydro and sit well below the national average. Ontario uses mandatory time-of-use pricing with on-peak, mid-peak and off-peak windows that shift between summer and winter schedules, and also offers an optional tiered plan. Most provinces add a fixed monthly service charge on top of the per-kWh energy charge.

When tumble dryer costs peak in Canada

Winter dominates in most of Canada, with December through February bringing the highest bills wherever heating is electric. Homes on natural gas heat see a much flatter annual profile, with a modest summer bump from air conditioning.

Local tip. In Ontario, shifting laundry and dishwashing to after 7pm on weekdays — or any time at weekends, when the entire day is off-peak — moves that consumption to roughly half the on-peak rate at no cost to you.

How electricity is billed in the Eurozone

Eurozone electricity averages around €0.285 per kWh but the variation between member states is large — Germany and Denmark sit well above the average while France, helped by its nuclear fleet, sits below it. Bills typically combine an energy charge, a network or grid fee, and a substantial tax and levy component that in several countries exceeds the cost of the energy itself. Many suppliers offer day/night or dynamic hourly pricing, and dynamic tariffs linked to the wholesale spot market have become widely available.

When tumble dryer costs peak in the Eurozone

Winter drives the peak in most of the eurozone, particularly in countries with significant electric heating. Southern member states such as Spain, Italy and Greece increasingly see a comparable summer peak from air conditioning.

Local tip. Check how much of your bill is energy and how much is network fees and taxes. In several member states the non-energy component is more than half the total, which means using less electricity saves less than the headline rate suggests.

How electricity is billed in India

Indian domestic tariffs are almost always slab-based, and this is what makes estimating a bill genuinely difficult. The first 100 units might cost ₹4–5, the next 200 units ₹6–7, and consumption beyond 400 units ₹8–9 or more. Crucially, in many states crossing a slab boundary re-prices your entire consumption at the higher rate rather than just the excess units. On top of the energy charge sit a fixed charge based on sanctioned load, an electricity duty, and often a fuel surcharge that varies month to month. Rates differ substantially between state discoms, so a Maharashtra bill and a Delhi bill for identical usage will differ.

When tumble dryer costs peak in India

Costs peak from April to June across most of the country, when air conditioners, coolers and fans run hardest. This is also exactly when households are most likely to cross into a higher tariff slab, which is why summer bills often rise faster than summer consumption does.

Local tip. Find out where your next slab boundary sits and how close you are to it. Because many discoms re-price all units at the higher rate once you cross, cutting consumption by twenty or thirty units can occasionally save several hundred rupees — far more than the units themselves are worth.

How electricity is billed in the United Kingdom

An electricity bill separates variable kWh charges from a fixed standing charge. For the July-September 2026 period the Ofgem Great Britain Direct Debit standard-variable reference is 26.11p/kWh plus 57.19p/day, including 5% VAT. It applies as an average reference across England, Scotland and Wales, not to every UK household or Northern Ireland. Your own supplier, region, payment method or fixed-rate plan can differ. With a time-of-use plan, price each charging or appliance session using the rate in that window.

When tumble dryer costs peak in the United Kingdom

UK electricity costs rise through the winter, peaking in December and January when lighting hours are longest and any electric heating is working hardest. Air conditioning is rare enough that summer is generally the cheapest quarter.

Local tip. Use your bill’s variable price per kWh when estimating an extra appliance. Do not add a standing charge to each device, or add VAT again if it is included. An off-peak EV rate can come with different daytime pricing; compare the whole household bill.

How electricity is billed in the United States

Most US households are billed a flat per-kWh rate plus a fixed monthly customer charge of roughly $8 to $15. Rates vary enormously by state — Hawaii runs above 50¢/kWh while Idaho and Utah sit near 12–13¢. Many utilities now offer optional time-of-use plans where afternoon and early-evening power costs substantially more than overnight power, and a growing number of states are making time-of-use the default for new connections. Some utilities also apply seasonal rates, with summer kWh priced higher than winter to reflect air-conditioning demand.

When tumble dryer costs peak in the United States

Costs peak in July and August across most of the country, when cooling load is highest and many utilities switch to summer pricing at the same time. In the Northeast and Upper Midwest a second, smaller peak appears in January and February wherever homes use electric resistance heating or heat pumps.

Local tip. Check whether your utility offers a time-of-use plan before you assume a flat rate. If you can move laundry, dishwashing and EV charging to overnight hours, the off-peak rate is frequently less than half the on-peak rate and the switch costs nothing.

Energy per cycle (kWh) = Watts ÷ 1000 × Cycle hours

Cost per cycle = Energy per cycle × Tariff

Annual cost = Cost per cycle × Cycles per week × 52

Set 'days' to cycles per month. Heat pump dryers draw far fewer watts but run longer; the calculator handles that correctly because it multiplies watts by actual runtime rather than assuming a fixed cycle.

What is outside this cost estimate?

Product maintenance, repairs, financing and a guaranteed performance level are not included. Where a grid-carbon estimate appears, it uses the illustrative factor 0.371 kg CO₂/kWh, not a live local measurement or full lifecycle calculation. No petrol-versus-EV emissions comparison is inferred from fuel litres.

The local worked examples above use this page’s currency. The global calculator guide contains additional appliance assumptions and comparison examples.

Tumble Dryer costs in the United States — FAQ

How much does a tumble dryer cost per cycle?

A condenser or vented dryer using about 3.75 kWh a cycle costs roughly $0.64 in the US, £0.93 in the UK, ₹30 in India and A$1.24 in Australia. A heat pump dryer typically costs less than half that per load.

Are heat pump tumble dryers worth the extra money?

If you dry more than two loads a week, usually yes. They use roughly 50–60% less electricity per load. On three loads a week the saving is often $70–$120 a year, so a price premium of $300–$400 pays back in three to five years, and faster in high-tariff markets.

How much electricity does a tumble dryer use per year?

Three condenser loads a week at 3.75 kWh is about 585 kWh a year — often 10–15% of a household's total electricity. A heat pump doing the same work uses roughly 310 kWh.

Is the US starting rate a live quote?

No. The tariff note names the scope and source of the starting rate where available; otherwise it is explicitly illustrative. Replace it with your own variable electricity rate. Keep fixed connection charges separate.

Power, usage, fuel prices and purchase prices are example assumptions. Grid-carbon factors are illustrative, not live or lifecycle data. Read our calculation and sourcing method.

Worked example in South Africa

The starting example uses 2,500 W for 1.5 hours/day at 100% duty. That is 3.75 kWh/day and R130.50 for 12 days at R2.9/kWh. This is full-power arithmetic, not a claim that every appliance runs continuously. Lower the duty cycle if the rated power cycles off.

Average duty	Daily kWh	12-day cost
50%	1.875	R65.25
75%	2.812	R97.88
100%	3.750	R130.50

These examples use stated assumptions, not a product test. Change the form inputs for your own calculation. The annual result assumes the same daily use for 365 days; for a seasonal appliance, multiply daily cost by actual seasonal operating days instead.

How electricity is billed in South Africa

Most South African households buy electricity on a prepaid meter, and Eskom's Homepower and municipal prepaid tariffs are block-based: the first block of units each month is cheapest, and the rate steps up as you buy more within the same calendar month. Because the blocks reset monthly, buying a large amount of electricity in one go pushes you into the higher blocks immediately. Postpaid customers additionally pay a fixed basic charge. Tariffs have risen far faster than general inflation for over a decade, and load shedding schedules add a further complication by concentrating consumption into fewer hours.

When tumble dryer costs peak in South Africa

Winter, from June to August, brings the highest bills as geysers work harder against colder inlet water and electric heating comes on. Highveld winters in particular drive a sharp seasonal increase.

Local tip. The geyser is typically 30 to 40 percent of a South African household's electricity use. Fitting a geyser blanket and a timer, and dropping the thermostat to 55°C, is the highest-return efficiency spend available — usually recovered within a few months.

How this calculator works

Units per session = Watts at the wall ÷ 1000 × Hours played

Monthly cost = Units per session × Sessions per month × Tariff

Add monitor, speakers and peripherals separately, or include them in the wattage

Use measured wall wattage if you have a plug meter — PSU rating is not consumption. A '850 W power supply' does not draw 850 W; a system with that PSU typically pulls 300–500 W under gaming load.

Worked example

A 450 W gaming PC plus a 40 W monitor, four hours a day: 0.49 kW × 4 = 1.96 kWh a day, about 59 kWh a month. At $0.17 that is $10 a month, roughly $120 a year. Leaving the same machine idling at 60 W for the other 20 hours adds another $6 a month.

Typical system power draw

System	Gaming load	Idle
Office desktop	60 – 100 W	25 – 40 W
Gaming laptop	120 – 200 W	20 – 35 W
Mid-range gaming PC	250 – 350 W	50 – 70 W
High-end gaming PC	400 – 550 W	60 – 90 W
Enthusiast / 4K rig	600 – 800 W	80 – 120 W
PlayStation 5	180 – 220 W	1.5 W (rest mode)
Xbox Series X	160 – 210 W	10 – 15 W
27in gaming monitor	30 – 55 W	0.5 W

Reduce your rig's running cost

Cap the frame rate. Locking to your monitor's refresh rate can cut GPU power 20–40% with no visible difference.
Undervolt the GPU. A modest undervolt often keeps 95% of performance for 70% of the power, and runs quieter.
Enable sleep after 15 minutes. Idle desktop time is pure waste and adds up to more than most people expect.
Turn off rest-mode downloads when unused. Consoles in networked standby can draw 10–15 W around the clock.
Use the monitor's eco preset. Peak brightness on a large panel can double its draw.
Measure, do not guess. A $15 plug-in energy meter gives you the real number in five minutes.

Frequently asked questions

How much does it cost to run a gaming PC per hour?

A mid-range system drawing about 300 W costs roughly $0.05 an hour in the US, £0.07 in the UK and ₹2.40 in India. A high-end 600 W rig with monitor costs about double that. Enter your measured wattage above for your exact figure.

Does a 850W power supply use 850W?

No. The PSU rating is the maximum it can deliver, not what the system consumes. A typical build with an 850 W unit draws 300–500 W while gaming and 50–90 W at idle. Only a plug-in meter tells you the true number.

How much electricity does a gaming PC use per month?

Four hours of gaming a day on a 450 W system plus monitor is about 59 kWh a month, roughly $10 in the US or £15 in the UK. Add idle time and always-on downloads and it can exceed 80 kWh.

Is a console cheaper to run than a gaming PC?

Usually yes. A PS5 or Xbox Series X draws around 180–220 W while gaming, compared with 300–600 W for an equivalent gaming PC. Over four hours a day the console typically costs about half as much.

Does leaving a PC on overnight cost much?

At a 60 W idle, twelve overnight hours is 0.72 kWh — about $0.12 a night, or $44 a year. Not huge, but sleep mode makes it essentially free and costs nothing to enable.

How this calculator works

Units per day = Watts ÷ 1000 × 24

Annual cost = Watts ÷ 1000 × 24 × 365 × Tariff

Rule of thumb: each continuous watt costs about 8.8 kWh per year

For always-on equipment there is a shortcut worth memorising: one watt running continuously uses 8.76 kWh a year. Multiply your device's average draw by 8.76 to get annual kWh, then by your tariff. At 17¢/kWh, every continuous watt costs about $1.49 a year — so a 100 W server is roughly $149 annually. Measure at the wall with a plug meter if you can; idle and loaded draw often differ by a factor of three.

Worked example

A home server averaging 100 W uses 876 kWh a year — about $149 at 17¢/kWh. A multi-GPU rig at 1,200 W uses 10,512 kWh, or $1,787 a year. Dropping the server from 100 W to 30 W by moving to a low-power NAS saves $104 every year.

Annual cost of always-on devices

Device	Typical draw	Annual kWh	Annual cost at 17¢
Raspberry Pi	5 W	44 kWh	$7
Mini PC	15 W	131 kWh	$22
2-bay NAS	30 W	263 kWh	$45
4-bay NAS	55 W	482 kWh	$82
Home server (idle)	80 W	701 kWh	$119
Home server (loaded)	200 W	1,752 kWh	$298
Single GPU rig	350 W	3,066 kWh	$521
Multi-GPU rig	1,200 W	10,512 kWh	$1,787

Cutting always-on costs

Measure, do not estimate. A plug-in energy meter costs very little and idle draw is almost always different from what the spec sheet implies.
Right-size the hardware. An old desktop repurposed as a server often draws 80–120 W idle where a purpose-built mini PC or NAS does the same job at 15–30 W.
Enable disk spin-down and CPU power states. Default server settings frequently disable exactly the features that would cut idle draw.
Consolidate. Three devices at 30 W each cost more than one at 60 W doing all three jobs.
Consider whether it needs to be always on. Wake-on-LAN plus a scheduled shutdown can cut runtime by two-thirds for a machine you only use in the evenings.

Frequently asked questions

How much does it cost to run a server 24/7?

Multiply the average draw in watts by 8.76 to get annual kWh, then by your tariff. A 100 W server is about 876 kWh, roughly $149 a year at 17¢/kWh.

How much electricity does a NAS use?

A 2-bay consumer NAS typically averages 25 to 35 W including drives, about 260 to 300 kWh a year. A 4-bay unit is roughly double that.

Is a mining rig profitable given electricity costs?

That depends entirely on your tariff and the coin, and it is a calculation you should redo regularly. A 1,200 W rig costs around $1,800 a year at 17¢/kWh — the electricity alone frequently exceeds the revenue.

How much does one watt cost per year?

A watt running continuously uses 8.76 kWh a year. At 17¢/kWh that is about $1.49; at 25p/kWh about £2.19; at ₹8/kWh about ₹70.

Does a computer use less power when idle?

Modern hardware, yes — often a third or less of loaded draw, provided power management is enabled. Older hardware and servers with power saving disabled can idle at close to full consumption.
