How this calculator works

Storage units = Watts ÷ 1000 × Heating hours × Days

Instant units = Watts ÷ 1000 × Running hours × Days

Storage adds standby loss; instant adds no standby but heats on demand

This calculator gives each appliance its own hours field, because that is the whole point of the comparison — comparing a 4,500 W instant heater and a 2,000 W storage heater over the same hours would be meaningless. A storage geyser heats the full tank and then reheats it periodically as it cools, so its effective daily heating time includes standby losses. An instant heater runs only while a tap is open. For a household of four taking 20-minute-total showers, 0.33 hours a day of instant running against 1.2 hours of storage heating is realistic.

Worked example

A 2,000 W storage geyser heating 1.2 hours a day for 330 days uses 792 units — ₹6,336 at ₹8/kWh. A 4,500 W instant heater running 0.33 hours a day uses 490 units, or ₹3,920. The instant unit saves about ₹2,416 a year here, and costs less to buy — but only because this household's usage is short and spread out.

Instant vs storage water heater

	Storage geyser	Instant geyser
Typical power	2,000 W	3,000–6,000 W
Hot water available	Tank full, then wait	Unlimited, on demand
Standby heat loss	Yes, continuous	None
Flow rate limit	None until tank empties	Limited by power
Best for	Baths, multiple taps	Short showers, single point
Purchase price	₹8,000–14,000	₹4,000–8,000
Wiring requirement	Standard circuit	Heavy dedicated circuit
Winter performance	Consistent	Reduced flow rate

Picking the right type

Short, spread-out usage favours instant. If people shower at different times and nobody takes a bath, you avoid keeping a tank hot all day for a few minutes of use.
Baths and simultaneous taps favour storage. An instant heater's flow rate is limited by its power, and in winter it may not manage a comfortable bath-filling flow at all.
Check your wiring before buying instant. A 4,500 W or 6,000 W instant heater needs a dedicated heavy circuit. Retrofitting that can cost more than the appliance.
If you have a storage geyser, put it on a timer. Heating the tank for an hour before the morning rush costs far less than keeping it hot for twenty-four.
Insulate the storage tank and its pipes. Standby loss is the storage geyser's only structural disadvantage, and insulation directly reduces it.
Lower the thermostat to 55–60°C. Higher settings increase both standby loss and scale formation, without making showers any better.

Frequently asked questions

Which uses more electricity, instant or storage geyser?

It depends on usage, not on wattage. An instant heater draws two to three times the power but runs a quarter of the time. For short, spread-out showers the instant unit usually uses less overall; for baths and heavy simultaneous use, storage wins.

Does an instant geyser really save electricity?

It eliminates standby loss entirely, which is a real saving. But it can only deliver as much hot water per minute as its power allows, so heavy users end up running it longer and the advantage shrinks.

Why does my instant geyser give less hot water in winter?

Because the incoming water is colder, so the same heating power raises it fewer degrees. The heater compensates by reducing flow, which is why winter showers from an instant unit feel weaker.

Is a 3kW or 4.5kW instant geyser better?

The higher rating gives a better flow rate at the same temperature rise, which matters in winter. It uses the same energy per litre heated — more power simply means faster, not more expensive per litre.

Should I switch off my storage geyser when not in use?

Yes, or better, put it on a timer. A tank held hot all day loses heat continuously and reheats to compensate. Heating it for an hour before you need it avoids most of that loss.

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 instant vs storage 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 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 instant vs storage 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 instant vs storage 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 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 instant vs storage 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 Geyser vs Solar Water Heater Cost Calculator

A solar water heater has a high upfront cost and almost no running cost. An electric geyser is the reverse. Because water heating is often the largest single load in a home, this is one of the few appliance decisions where the payback is measured in years rather than decades.

How this calculator works

Electric geyser units = Watts ÷ 1000 × Hours × Days

Solar backup units = Same, but only for the electric backup element

Payback years = Extra system cost ÷ Annual saving

A solar water heater is modelled here through its duty cycle. On a clear day it uses no electricity at all; on cloudy days and through winter mornings the electric backup element runs. Setting the solar system's duty cycle to 25% means the backup supplies roughly a quarter of the year's heating — a realistic figure for a well-sized system in a sunny climate. In a cloudier region use 40 to 50%. The wattage of both is the same because it is the same class of heating element; the difference is entirely how often it has to run.

Worked example

A 2,000 W geyser running 2 hours a day for 330 days uses 1,320 units a year — ₹10,560 at ₹8/kWh. A solar system whose backup runs 25% as often uses 330 units, or ₹2,640. That is a saving of ₹7,920 a year, so a ₹20,000 price difference pays back in 2.53 years. Over ten years the solar system is around ₹59,200 ahead.

Water heating options compared

System	Upfront	Annual running cost	Lifespan
Instant electric geyser	Low	High	8–10 yr
Storage electric geyser	Low–medium	High	10–12 yr
Solar with electric backup	High	Very low	15–20 yr
Heat pump water heater	High	Low	12–15 yr
Gas geyser	Medium	Medium	8–10 yr

Getting the payback down

Size the tank to your household, not the roof. An oversized solar tank means heating water nobody uses, and the backup element does that heating on cloudy days.
Use hot water in the afternoon and evening. That is when the tank is at its hottest and the backup is least likely to fire.
Insulate the pipe run. Uninsulated hot pipes between tank and tap waste heat on every draw, which the backup element then replaces.
Put the backup element on a timer. Left permanently enabled it will top up the tank overnight even when tomorrow will be sunny.
Descale in hard-water areas. Scale on the element and inside the collector reduces both solar gain and element efficiency.
Check for a subsidy. Solar water heating attracts capital subsidies in many markets, which can cut the payback period roughly in half.

Frequently asked questions

Is a solar water heater cheaper than an electric geyser?

Over its life, substantially. Running costs typically fall by 70 to 80%, and at normal usage the higher purchase price is repaid in two to four years. Over a 15-year lifespan the solar system is far ahead.

How much does a solar water heater save per year?

For a household using 2 hours of 2 kW heating a day, roughly 990 units a year — about ₹7,900 at ₹8/kWh or R2,870 at R2.90/kWh. The exact figure depends on how much sun your location gets.

Does a solar water heater work in winter?

It works, but at reduced output — which is exactly why they include an electric backup element. In winter the backup does more of the work, which is what the duty cycle field in the calculator represents.

What is the payback period of a solar water heater?

Typically two to four years at normal household usage, and faster where electricity is expensive or a subsidy applies. Light users with small hot water demand see longer paybacks.

How long does a solar water heater last?

Fifteen to twenty years for the collector, with the tank and backup element usually needing attention sooner. That long life is what makes the economics work.

Is a heat pump water heater better than solar?

A heat pump works day and night and in any weather, but uses electricity continuously at a COP of around 3. Solar uses none when the sun shines but needs backup when it does not. In sunny climates solar usually wins on running cost; in cloudy ones the heat pump is more predictable.

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 geyser vs solar 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.

Worked example in India

For equal useful heat, gas at ₹4.66/fuel kWh and 40% efficiency costs ₹11.65/useful kWh. Induction at ₹8/kWh and 85% efficiency costs ₹9.41/useful kWh. The lower figure wins only for these assumptions; a lower raw gas price does not by itself prove lower cooking cost.

Demand: 1.5 useful kWh/day	Gas	Induction
One day	₹17.48	₹14.12
30 cooking days	₹524.25	₹423.53
365 cooking days	₹6,378.38	₹5,152.94

These examples use stated assumptions, not a product test. Change the form inputs for your own calculation.

How this calculator works

Gas cost per useful kWh = Gas price per fuel kWh ÷ Gas efficiency

Induction cost per useful kWh = Electricity rate ÷ Induction efficiency

Annual cooking cost = Cost per useful kWh × Useful kWh per day × Days per year

Compare equal useful heat delivered to the food, not equal clock time at different burner powers. The 40% gas and 85% induction efficiencies are modelling assumptions. For LPG, an illustrative conversion is cylinder price ÷ (cylinder kg × 13.6 kWh/kg); fuel composition varies. Do not use your electricity price as the gas price. Fixed gas connection charges are excluded unless you can actually avoid them.

Worked example

Using illustrative inputs of ₹4.66 per fuel kWh for gas and ₹8/kWh for electricity: a 40% efficient gas burner costs ₹11.65 per useful kWh, while an 85% efficient induction hob costs ₹9.41. Induction is about 19% cheaper in this scenario. Other tariffs can reverse the result.

Cooking for less either way

Always use a lid. This is the single largest saving in any kitchen, on any fuel — often 30% or more on anything that simmers.
Match pan size to burner or ring. A small pan on a large gas burner sends the flame up the sides and wastes most of it. Induction only heats the pan footprint, so this matters less there.
Check your actual gas rate. Divide your cylinder price by 193 kWh for a 14.2 kg cylinder, or use your piped gas bill's per-unit rate. Regional prices vary enormously.
Induction needs ferrous pans. If a magnet does not stick to the base, it will not work. Replacing a full set of aluminium pans is a real cost to include in the decision.
A pressure cooker beats both. Cutting cooking time by two-thirds saves more than any change of fuel for dals, beans and meat.

Frequently asked questions

Is induction cooking cheaper than gas?

Not at every tariff. Divide each fuel price per kWh by its cooking efficiency. Induction costs less when electricity price divided by induction efficiency is lower than gas price divided by gas efficiency. Use the same useful heat demand for both.

How do I compare gas and electricity costs?

Convert both to cost per useful kWh. For LPG, divide the cylinder price by 193 kWh for a 14.2 kg cylinder to get the raw rate, then divide by 0.40 for burner efficiency. For induction, divide your electricity rate by 0.85.

How much energy is in an LPG cylinder?

About 13.6 kWh per kilogram, so a standard 14.2 kg domestic cylinder holds roughly 193 kWh of energy — of which around 77 kWh actually reaches the food at typical burner efficiency.

Does induction cook faster than gas?

Yes, noticeably. Because far more of the energy goes into the pan, an induction hob typically boils water in around half the time of a comparable gas burner.

Is an electric coil hob as cheap as induction?

No. A coil or ceramic hob is around 70% efficient against induction's 85%, so it costs roughly 20% more per meal on the same electricity rate, and takes longer.

What about the cost of new pans?

It is a genuine one-off cost. Induction needs magnetic pan bases, so aluminium and copper cookware will not work. Budget for it when comparing, especially if you are replacing a full set.

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 gas vs induction 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.

Worked example in South Africa

For equal useful heat, gas at R1.6/fuel kWh and 40% efficiency costs R4.00/useful kWh. Induction at R2.9/kWh and 85% efficiency costs R3.41/useful kWh. The lower figure wins only for these assumptions; a lower raw gas price does not by itself prove lower cooking cost.

Demand: 1.5 useful kWh/day	Gas	Induction
One day	R6.00	R5.12
30 cooking days	R180.00	R153.53
365 cooking days	R2,190.00	R1,867.94

How electricity is billed in South Africa

When gas vs induction 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.

How this calculator works

Gas cost per useful kWh = Gas price per fuel kWh ÷ Gas efficiency

Induction cost per useful kWh = Electricity rate ÷ Induction efficiency

Annual cooking cost = Cost per useful kWh × Useful kWh per day × Days per year

Air Fryer vs Oven Running Cost Calculator

An air fryer can use less electricity for a small meal because it heats a smaller cavity and may cook for less time. Compare the same meal using separate oven and air-fryer cooking times, including preheating. Multiple air-fryer batches can reduce or remove the saving.

Worked example in United Kingdom

At £0.2611/kWh, the illustrated Electric oven uses 1.200 kWh per session, versus 0.250 kWh for Air fryer. The model uses 0.833 versus 0.333 hours, at 60% versus 50% average duty. These are explicit usage assumptions, not local product measurements.

Option	Energy / session	Cost / session	300 uses / year
Electric oven	1.200 kWh	£0.31	£94.00
Air fryer	0.250 kWh	£0.07	£19.58

How this calculator works

Energy per session = Watts × Duty ÷ 100 ÷ 1000 × Minutes ÷ 60

Annual cost = Energy per session × Sessions per year × Tariff

Duty cycle matters: the element cycles once the cavity is at temperature

Enter total minutes including any preheat. The duty factor is the average share of rated power across that entire session. Use different times for the two appliances, and include all batches needed for the same amount of food. A plug-in energy meter is a better basis than a generic preset when safely suitable for the appliance.

Worked example

In a worked example, a 2,400 W oven at 60% average duty for 50 minutes uses 1.20 kWh. A 1,500 W air fryer at 50% duty for 20 minutes uses 0.25 kWh. At £0.2611/kWh that is 31.33p versus 6.53p per meal, or about £74.41 saved across 300 sessions. These are example powers and duty factors, not a measured product test.

Illustrative cooking sessions at £0.2611/kWh

Appliance	Power	Minutes	Average duty	kWh	Energy cost
Electric oven	2,400 W	50	60%	1.20	£0.3133
Air fryer	1,500 W	20	50%	0.25	£0.0653
Two air-fryer batches	1,500 W	40	50%	0.50	£0.1306

Cooking for less

Match the appliance to the portion. An air fryer wins on small portions and loses on a Sunday roast — you would have to run it in three batches.
Stop preheating the oven for most things. Unless you are baking bread or pastry, putting food in from cold saves several minutes at full power.
Batch cook in the oven. If the oven is on anyway, filling every shelf makes each dish far cheaper than cooking it separately later.
A microwave is cheaper than both for reheating and for vegetables. It heats the food directly rather than heating a cavity of air around it.
Do not trust the slow cooker myth. A 200 W slow cooker over six hours uses as much as an oven for fifty minutes. It is convenient and cheap per portion for large batches, but not automatically cheap.

Frequently asked questions

How much cheaper is an air fryer than an oven?

For the illustrated small-meal comparison, 0.25 kWh versus 1.20 kWh is about 79% less electricity. This is not a universal saving: cooking time, average duty, portion size and the number of batches all change the result.

How much does an air fryer cost to run for 20 minutes?

A 1,500 W example averaging 50% duty uses 0.25 kWh in 20 minutes. At £0.2611/kWh this is about 6.53p. At full continuous power it would use 0.50 kWh and cost 13.06p. Include preheating in the session time.

How much does an oven cost per hour?

A 2,400 W oven averaging 60% duty uses 1.44 kWh in an hour, or about 37.60p at £0.2611/kWh. Full-power preheating costs more per minute than thermostatic operation; measure the complete cooking session when comparing appliances.

Is an air fryer just a small convection oven?

Essentially, yes — a small cavity with a powerful fan. The efficiency gain is entirely from the size and the speed, not from any different cooking physics.

What is the cheapest way to cook?

For reheating and small portions, the microwave. For small crisped portions, the air fryer. For multiple dishes at once, a full oven used to capacity. The expensive case is always running a large appliance for a small amount of food.

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 air fryer vs oven 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 this calculator works

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 air fryer vs oven 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.

Compare cooking and water heating energy costs

An instant versus storage geyser comparison depends on hot-water demand, heating efficiency and storage losses. For gas versus induction cooking, use comparable cooking tasks, actual fuel prices and realistic efficiency assumptions. The lower energy bill depends on your usage and does not necessarily mean the lower total ownership cost.
