Inputs
Use the power rating on the appliance label or manual. If your oven cycles on and off, use an estimated average power rather than the maximum rating.
Kitchen energy calculator
Air fryer vs oven cost calculator
Compare the electricity cost of cooking with an air fryer and an oven. Enter appliance power, cooking time, electricity price, and weekly use to see the difference.
Method
Cost equals appliance power multiplied by cooking hours and electricity price. Weekly and yearly figures multiply that per-cook cost by use frequency.
Result
This compares electricity only. It does not account for preheating, food quantity, cooking quality, standing charges, or gas ovens.
