How much electricity does an air fryer use? Formula and cost examples
An 1800 W air fryer running for 20 minutes uses at most about 0.6 kWh. Actual use is often lower because the heater cycles.
An 1800 W air fryer running for 20 minutes uses at most about 0.6 kWh. Multiply that by the full price per kWh on your bill. Actual use is often lower because the heater usually cycles after reaching temperature.
The exact cost depends on power, time, temperature, portion size, and your tariff. Rated-power calculations show a useful maximum; a plug-in energy meter gives the most accurate result.
Maximum energy use by time
| Power | 10 min | 20 min | 30 min |
|---|---|---|---|
| 1400 W | 0.23 kWh | 0.47 kWh | 0.70 kWh |
| 1800 W | 0.30 kWh | 0.60 kWh | 0.90 kWh |
| 2000 W | 0.33 kWh | 0.67 kWh | 1.00 kWh |
| 2470 W | 0.41 kWh | 0.82 kWh | 1.24 kWh |

How to calculate air fryer energy use
Energy in kWh = power in kW × time in hours. For 1800 W over 20 minutes: 1.8 × 0.333 = about 0.6 kWh. Multiply the result by your full cost per kWh.
Typical air fryer power
Small models
About 1200–1500 W.
Medium models
About 1500–2000 W.
Large and dual-basket models
Often 1800–2700 W. Higher power does not automatically mean a higher total cost if cooking is faster.
Does an air fryer use less electricity than an oven?
Often yes for small and medium portions because the chamber is smaller and cooking is faster. A full-size oven may be more practical for several trays or a large batch that would require multiple air fryer cycles.
Does it draw full power all the time?
Usually not. Rated wattage is the maximum. The heater works hardest while warming up, then cycles to maintain temperature.
How to measure your exact use
Connect a plug-in energy meter
Plug the meter into the wall and the air fryer into the meter.
Reset and cook normally
Read the kWh value after the program finishes.
Multiply by your tariff
Repeat for several meals to learn their actual running cost.
