Air Fryer vs Oven Electricity Cost Calculator

Is an air fryer cheaper to run than an electric oven?

Compare the estimated electricity cost of cooking with an air fryer and an electric oven. Enter the power rating and cooking time for each appliance, along with your electricity price, to see the estimated cost per meal and the difference over a week, month and year.

Absolutely, my good friend. 😄⚡🍟 Let's give the Air Fryer vs Oven Electricity Cost Calculator the same useful treatment.

Put the following under the existing calculator and its disclaimer, just as we did with the heater page.

Is an Air Fryer Cheaper to Run Than an Oven?

An air fryer can often cost less to run than a conventional electric oven for smaller meals, but the answer depends on more than the wattage printed on each appliance.

The total electricity cost depends on factors including the appliance's power, cooking time, preheating time, how often its heating element cycles on and off, and the amount of food being cooked.

For example, using an electricity price of 26p per kWh:

An air fryer rated at 1,500W, running at full power for 20 minutes, would use approximately 0.5 kWh and cost about 13p.

An electric oven rated at 2,500W, running at full power for 40 minutes, would use approximately 1.67 kWh and cost about 43p.

However, these are simple full-power examples. Real appliances commonly cycle their heating elements rather than drawing their maximum rated power continuously.

Why can an air fryer cost less to run?

Air fryers generally have a much smaller cooking chamber than conventional ovens and can often cook smaller quantities of food more quickly.

This can mean less space needs to be heated and the appliance may need to operate for less time.

However, this does not mean an air fryer will always be the cheaper option for every meal.

If a conventional oven is being used to cook several portions or several foods at the same time, comparing one air-fryer load with the whole oven may not be a fair comparison.

How is the electricity cost calculated?

The basic calculation is:

Power in kW × cooking time in hours × electricity price per kWh = estimated electricity cost

For example, a 1,500W air fryer is equivalent to 1.5kW.

If it operates at full power for 20 minutes, the calculation at 26p per kWh is:

1.5kW × 0.333 hours × £0.26 = approximately £0.13

Our calculator also lets you adjust the average power use percentage for each appliance. This can be useful for exploring the effect of heating elements cycling on and off during cooking.

Why cooking time matters

Looking only at appliance wattage can be misleading.

For example, an air fryer may have a relatively high power rating, but if it cooks the same meal considerably faster than an oven, its total electricity consumption may still be lower.

This is why EnergyCosted compares the estimated electricity used for the complete cooking time, rather than simply comparing the wattage of the two appliances.

What about oven preheating?

Preheating can add to the electricity used when cooking with an oven.

If your oven needs to preheat before the food is placed inside, include that additional time when entering the oven cooking time if you want it reflected in your comparison.

Some air-fryer recipes also recommend preheating, so the same principle applies.

For the fairest comparison, include all the appliance operating time required to prepare an equivalent meal.

Comparing equivalent meals

Try to compare like with like.

A small air fryer may be economical for preparing one or two portions, while a larger oven may be able to cook considerably more food at once.

If several separate air-fryer batches would be required to cook the same quantity that an oven can prepare in one go, those additional batches should be taken into account.

Frequently Asked Questions

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

Using a 1,500W air fryer at continuous full power and an electricity price of 26p per kWh, 20 minutes would cost approximately 13p.

Actual consumption may differ because the heating element may cycle on and off during cooking.

How much does a 2,500W oven cost to run for one hour?

At continuous full power and an electricity price of 26p per kWh, the calculation would be:

2.5kW × 1 hour × £0.26 = £0.65

So the theoretical full-power cost would be approximately 65p for one hour.

An oven may not draw its maximum rated power continuously because its heating elements can cycle as it maintains the selected temperature.

Does an air fryer always use less electricity than an oven?

No.

The result depends on the appliances, cooking times, temperature settings, heating cycles and quantity of food being prepared.

Air fryers can have an advantage for smaller meals because of their smaller cooking chamber and potentially shorter cooking time, but an oven may be more practical when cooking larger quantities or several foods together.

Should I compare wattage or kWh?

Wattage tells you the appliance's power rating, while kilowatt-hours (kWh) measure the amount of electrical energy used over time.

Electricity is normally charged by kWh, so both power and operating time matter when estimating the cost of cooking.

Can I enter my own electricity price?

Yes. Enter the price you actually pay per kWh into the calculator. This gives you a more relevant estimate than relying on the example electricity price used on this page.
