Do Air Fryers Use a Lot of Electricity?
No, not the way people worry they do. Most air fryers pull somewhere between 800 and 2000 watts, and they run for well under an hour, so a typical cook uses a fraction of one unit of electricity. My Platinum 7.6L basket is a 2000-watt unit, and a 20-minute cook on it costs less than most people guess.
The number you actually care about isn't the wattage on the label. It's what one cook costs on your bill, and that depends on your electricity rate, not mine. So instead of quoting you a price from a country you might not live in, this page hands you the arithmetic to work out your own.
Cooking a smaller portion is where the air fryer saves the most. Get the time and temp right so you're not running it twice.

Every cost starts here. The wattage is printed on a sticker on the base of the machine, or in the manual, usually next to the voltage. Most sit between 800 and 2000 watts. Bigger baskets tend to pull more, because there's more air and more space to heat.
Once you have that one number, everything else is multiplication.
Work out your own cost per cook
Electricity is billed by the kilowatt-hour, which is just a 1000-watt appliance running for one hour. Two steps get you there.
- Divide your air fryer's watts by 1000 to get kilowatts. A 1500-watt unit is 1.5 kW.
- Multiply that by how long it runs, in hours. Thirty minutes is 0.5.
That gives you the kilowatt-hours a cook uses. Multiply that by your price per unit — it's on your bill — and you have the cost. The table below does the first part for you. Find the row nearest your wattage, read across to your cook length, then multiply that figure by your own rate.
| Air fryer wattage | 15-min cook | 30-min cook | 45-min cook |
|---|---|---|---|
| 800 W | 0.20 kWh | 0.40 kWh | 0.60 kWh |
| 1200 W | 0.30 kWh | 0.60 kWh | 0.90 kWh |
| 1500 W | 0.38 kWh | 0.75 kWh | 1.13 kWh |
| 2000 W | 0.50 kWh | 1.00 kWh | 1.50 kWh |
The whole formula, one line
(watts ÷ 1000) × hours running × your price per kWh = the cost of that cook. Say your unit is 1500 watts and you run it half an hour: that's 0.75 kWh. If you pay 20 cents a unit, the cook cost you about 15 cents. Swap in your own rate and your own wattage and the answer is yours, not a stranger's.
Why the label wattage overstates it
The table above is a ceiling, not the real figure. An air fryer doesn't hold full power the whole time. It heats hard to reach the temperature you set, then the element clicks off and only the fan keeps running, which sips a handful of watts. It clicks back on when the heat drops, off again when it recovers.
So over a full cook the machine spends a good chunk of its time idling rather than pulling its rated wattage. Your real cost lands below the table figure, not above it. That's worth knowing, because most cost breakdowns online multiply full wattage by full time and quietly overcharge the air fryer.
Air fryer versus a full oven
This is the comparison everyone actually wants, and for small amounts it isn't close. A full electric oven pulls somewhere around 2000 to 5000 watts, it has a big cavity to bring up to temperature, and it usually wants ten minutes of preheating before the food goes in. The air fryer heats a small box, gets there fast, and cooks in less time. Less space, less time, less electricity.
This clicked for me on leftover pizza. I usually have a couple of slices in the fridge, and I'd always reheated them in the microwave or, worse, fired up the whole oven. One night I ran two slices in the basket for 3–4 minutes at 180°C, about 350°F. The cheese melted properly, the base stayed firm, and it landed me that I'd heated a 7.6L basket for two slices instead of a whole oven. The pizza was better and the electricity barely registered.
When the oven is actually cheaper
Here's the part the "air fryers save you money" headlines skip. The saving comes from cooking a small portion in a small space. Take the portion up to a full family batch and the maths flips.
If a meal needs two or three back-to-back rounds in the basket because everything has to sit in a single layer, you're paying to reheat that little box two or three times over. An oven brings its cavity up to temperature once and then cooks the whole tray at once. Past a certain amount of food, that single heat-up wins. I'd rather tell you that than pretend the air fryer is the cheaper choice for everything, because for cooking-for-four it often isn't.
Rough rule from my own cooking: for one or two people the air fryer is the cheaper appliance almost every time. Once you're feeding four or more and running multiple batches, price up the oven before you assume the fryer wins.
Does it use electricity when it's off?
A little, if you leave it plugged in. Most units keep the display or a standby circuit alive, which draws a trickle — nothing next to the cost of actually cooking. If you want that gone, switch it off at the wall or unplug it. It's a tidy habit, not an emergency.
The short version
- No, an air fryer isn't a heavy user. Most are 800 to 2000 watts running for under an hour.
- Find your wattage on the base, divide by 1000, multiply by hours and by your own rate.
- The real cost sits below the on-paper figure, because the element idles once it's up to temperature.
- For one or two portions it beats the oven on electricity. For a big batch that needs several rounds, the oven can win.
- Unplug it if you want to kill the standby trickle.
Work it out once with your own numbers and you'll stop wondering. It's cheaper than the worry.
