- Find your air fryer's power on its rating plate, in watts. Cost = kilowatts x hours x your unit rate.
- For example, if an air fryer is rated at 1,500 W, 20 minutes at full power costs 13.2p at 26.32p per kWh.2
- That is the most it can use at full power. If it switches off and on to hold the temperature, it uses less.

Air fryer or oven?
The government's Home Energy Model uses 0.59 kWh for one use of an electric oven (15.5p). Compare that with your air fryer's power and cooking time.1
