What does it cost to run an air fryer? The math nobody else publishes
Air fryers are sold on energy savings, yet no big guide puts a number on it. Here's the actual arithmetic — reproducible, with a calculator you can put your own machine into.

The direct answer
A typical air fryer draws 1,400–1,800 watts. A 20-minute cook uses about half a kilowatt-hour, which costs roughly 8–9 centsat the U.S. average electricity rate. Even used most days, that's only a few dollars a month. The real saving isn't versus other small appliances — it's versus heating a full-size oven for a small job.
Every air fryer is marketed on the same promise — uses less energy than your oven — and yet the big ranking guides never tell you the actual number. That's the gap Preheat Club was built to fill. The math isn't hard, and once you see it you'll be able to work out the running cost of anything in your kitchen.
The formula (it's just three numbers)
Electricity is billed per kilowatt-hour (kWh) — one kilowatt of power used for one hour. To get the cost of a single cook, you need three numbers:
- Power— your air fryer's wattage, printed on the label or in the manual (divide by 1,000 to get kilowatts).
- Time — how long it runs, in hours (20 minutes = 0.33 hours).
- Rate — what your utility charges per kWh (the U.S. average is about $0.17; your bill shows yours).
Multiply them: cost = kilowatts × hours × rate. For a 1,500-watt air fryer running 20 minutes at the average rate: 1.5 × 0.33 × $0.17 ≈ $0.085, about eight and a half cents. That's it. No magic, no marketing.
Do the math yourself
Air fryer running-cost calculator
Put in the wattage from your air fryer's label, how long you cook, and your electricity rate. The formula is just kilowatts × hours × your rate — no magic.
- Per cook
- 9¢
- 0.50 kWh used
- Per week
- $0.34
- 4 cooks
- Per year

- 52 weeks
Formula: (W ÷ 1000) × (minutes ÷ 60) × rate. Default rate is the U.S. EIA average residential price; your utility bill shows your real one. This is energy only — it does not include the food.
Typical costs, worked out
Here's what a few realistic scenarios come to at the U.S. average rate. Wattages are typical for the class; your machine's label is the source of truth, and the calculator above lets you use it.
| Scenario | Power × time | Cost |
|---|---|---|
| Quick reheat | 1,500 W × 8 min | ~3¢ |
| Batch of fries | 1,500 W × 20 min | ~9¢ |
| Bigger 1,750 W model | 1,750 W × 20 min | ~10¢ |
| Used 4× a week, a year | 1,500 W × 20 min × 208 | ~$18/yr |
Why it beats the oven (and why that's the real saving)
A full-size electric oven draws 2,000–3,000 watts and, crucially, has to heat a large cavity — ten minutes of preheating before you even start, then a longer cook. Running one for a 30-minute job can cost 35–45 cents, several times the air fryer's figure for the same food, because you're paying to heat all that empty space. That's the honest source of the “air fryers save energy” claim: not that they're magically efficient, but that they don't waste energy heating an oven you didn't need. We break the full comparison down in air fryer vs convection oven.
How to lower it further
- Skip unnecessary preheatingfor foods that don't need it — many don't.
- Cook full basketsso you're not running the machine twice for one meal.
- Use the air fryer instead of the ovenfor anything that fits — that's where the meaningful savings are.
- Know your rate.If you're on a time-of-use plan, cooking off-peak costs less; the calculator lets you plug in the off-peak rate.
How we picked
We did not lab-test this gear
Everyone in this category says they tested twenty air fryers. We have not lab-tested any of these, and we say so. What we did instead: compiled the published specifications — wattage, capacity, materials — worked out what each machine actually costs to run at the national electricity rate, read the manuals and owner reviews, and scored each one against a published rubric. The scores are judgments from documented research — not measurements we took, because we do not have a lab and we will not pretend we do. Where a number came from someone else's work, we name them in Sources.
