Air Fryer vs Oven Cost Calculator
Compare the electricity cost of cooking the same meal in an air fryer and an electric oven. Include every portion, cooking batch and preheat, then use your own tariff.
Match the meal before comparing costs
Portions and usable capacity matter. Energy Saving Trust's cooking comparison says a small meal often suits an air fryer, while an oven's larger capacity can offer value when cooking for a group or in bulk. One small air-fryer batch is not equivalent to a full oven meal.
Start with the same food and quantity at a similar temperature, and compare a similar finished result. Add all batches and any preheating actually needed. If you preheat once and then cook two batches, count that preheat once. Avoid assuming either appliance always needs no preheating.
Food held warm while later batches cook can add electricity use. Include that extra energy once in the whole-meal kWh total. If a separate appliance keeps food warm, measure or calculate its kWh separately and add it before entering the total.
Use whole-meal kWh or average electrical draw
A kWh reading over the entire task includes the power changes and thermostat cycling that occurred. Make sure it covers preheating and all cooking batches, and that household-meter readings are not being attributed to cooking while unrelated appliances run.
In average-power mode, use average electrical watts across the cooking time and, separately, across preheating. A label's maximum electrical rating multiplied by elapsed time is a continuous full-power scenario; it can differ from actual use. Do not apply another duty-cycle reduction to an average or a measured kWh total.
A full-size oven's air-fry setting and a countertop air fryer have different capacities and may use different amounts of energy. Compare the readings for the actual appliances and settings you use.
How the calculation works
Meal cost = whole-meal kWh × your rate in cents per kWh ÷ 100. In average-power mode, kWh = (average cooking watts × total cooking minutes + average preheating watts × total preheating minutes) ÷ 60,000. Cooking minutes exclude preheating. If preheating time is zero, preheating energy is zero.
The same tariff applies to both sides. If prices change during cooking, cost the energy in each rate period separately and add those costs. This tool does not apply fixed daily charges, which usually remain payable whichever appliance you choose.
An arithmetic example
Suppose your whole-meal entries are 0.4 kWh for an air fryer and 1 kWh for an electric oven. At 20 US cents/kWh, they cost $0.08 and $0.20. The difference is 0.6 kWh and $0.12 per meal.
Figures are rounded for display; differences use unrounded amounts.
These are hypothetical energy values to show the arithmetic, not model tests or recommended cooking times. Both entries must cook the same meal. The 20 US cents/kWh rate is illustrative, not the US average. This example stays fixed when you edit the calculator.
What published comparisons can tell you
CHOICE's air fryer and oven comparison describes Wendy Evans's three-meal home experiment using a new air fryer, an old electric oven and approximate smart-meter readings. It is useful evidence that meal choice, preheating and appliance condition matter. It is not a universal savings ratio or a runtime preset for your model.
Use your own readings to compare your meal at your tariff. For a single appliance, see the air fryer running-cost page or electric oven running-cost page. The United States electricity calculator can price a separate energy reading.
Common questions
Is an air fryer cheaper to run than an electric oven?
It depends on the energy needed for the same food, quantity and cooking result. A small meal can suit an air fryer, while an oven can cook more portions together. Add all batches, preheating and any extra electricity for keeping food warm, then compare total kWh at your tariff. This calculator does not assume a fixed saving.
Should I include preheating and extra batches?
Yes. A whole-meal kWh reading should include every batch and all preheating needed for that meal. In average-power mode, add cooking minutes across all batches and enter total preheating minutes separately. If one preheat serves several batches, count that preheat once. Follow your recipe and appliance instructions; neither appliance is assumed to need zero preheating.
Can I multiply the watts on the appliance label by cooking time?
That gives a continuous full-power scenario when the label states maximum electrical input. Thermostats and operating settings can change the actual draw. Use average electrical watts over the entered time for an estimate, or a whole-meal kWh measurement. Do not apply a second cycling reduction to measured kWh or average watts.
Does this compare an oven air-fry mode with a countertop air fryer?
A full-size oven with an air-fry mode is a different appliance from a countertop air fryer. You can compare their own whole-meal readings, but the mode name does not establish the same capacity or electricity use. This tool compares electricity running cost; it excludes gas ovens and purchase cost.
How do I include electricity used to keep earlier batches warm?
Include it once in the whole-meal kWh total. If another appliance keeps food warm, measure or calculate its additional energy separately and add it to the total before entering kWh. A reading that already covers that appliance must not have the same energy added again.
Is the US average electricity price my tariff?
No. The EIA US residential average is a dated benchmark, not your household tariff. Replace it with the applicable per-kWh usage rate from your utility bill. Fixed charges are excluded. If your price changes by time of day, cost the relevant periods separately.
