Energy calculator

Compare air fryer and oven cost.

Enter the wattage from the appliance label and the unit rate from your electricity bill. Results assume full rated power for the whole cook, so they are cautious estimates rather than meter readings.

Estimated air fryer cost

1700W for 20 minutes

£0.14per cook

Weekly: £0.69
Monthly average: £3.01
Annual: £36.10
Oven per cook: £0.31
Oven annual: £79.63
Estimated annual difference: £43.53 less with the air fryer

Formula: watts / 1000 x hours x electricity price per kWh. Real appliances cycle their heating elements, and ovens may cook more food at once, so compare the same meal and portion size.

Compare the same cooking job

A useful comparison uses the time needed to cook the same food quantity in each appliance. Air fryers often benefit from a shorter cook and smaller chamber, while an oven can become more practical when one large batch would require several air fryer rounds.

Check before using the result

Include preheating when you actually use it.
Compare one oven batch with every air fryer batch needed.
Treat savings as an estimate because heating elements cycle.

How to use this tool

Air fryers often use fewer minutes and a smaller chamber.
Large batches may still suit the oven.
Use your own p/kWh rate.

Plain safety rule

Treat every result as a starting point. Check early, leave space for airflow, and use a food thermometer for meat, fish and reheated food.

FAQ

Quick answers

Are air fryers always cheaper than ovens?

No. Food quantity, cooking time, appliance wattage and the number of batches determine the comparison.

Should preheating be included?

Include it when you normally preheat either appliance so the comparison represents the same cooking job.

What electricity rate should I use?

Use the unit rate in pence per kWh from your own bill rather than relying on the editable default.
