For example, if our electricity rate is $0.12 per kWh, using a microwave for 10 minutes (0.167 hours) at 900 watts (0.9 kW) would look like this:
Cost for Microwave = 0.9 kW x 0.167 hours x $0.12 = $0.018
Now, for the air fryer, if it’s used for 20 minutes (0.333 hours) at 1500 watts (1.5 kW):
Cost for Air Fryer = 1.5 kW x 0.333 hours x $0.12 = $0.060
From these calculations, it’s clear that using an air fryer becomes more expensive for longer cooking times compared to the microwave.
Conclusion: Making the Right Choice
Determining which appliance uses more electricity—microwave or air fryer—largely depends on individual cooking habits, the type of food being prepared, and the specific models in use. While air fryers typically operate at a higher wattage and may consume more energy overall due to longer cooking times, microwaves can often heat food much more quickly, leading to lower energy usage per session.
Ultimately, if you’re seeking quick heating solutions with less energy consumption, a microwave may be your best choice. However, for those desiring healthier, crispy outcomes without deep frying, investing in an air fryer is a worthwhile consideration, despite the higher operational costs.
