Do Air Fryers Use a Lot of Electricity? Running Costs vs an Oven

The sticker on the back of an air fryer says something like 1,500 or 1,700 watts. That looks alarming next to a phone charger, and it is the reason people ask whether these things are quietly running up the power bill.

They aren't. An air fryer is one of the cheaper ways to cook a hot meal, and for small portions it beats a full-size electric oven by a wide margin. A typical batch of fries costs about a nickel at average US prices.

The savings are smaller than the internet sometimes claims, though, and there are a few situations where the oven wins. This guide runs real metered numbers through 2026 US electricity prices so you can see both sides. We did not meter anything ourselves. The figures come from independent consumer testing, and the math is ours, shown in full.

The short answer

Watts on the label vs what it actually uses

The wattage rating is the most power the air fryer can pull at once. It pulls that while it heats up. After that, the thermostat switches the element on and off to hold your temperature, and the fan keeps running.

That cycling is why the label overstates real use. The UK consumer group Which? measured the energy an air fryer used across full cooks, preheat included, and published the results in October 2026. Divide each energy reading by its cook time and the air fryer averaged somewhere between about 0.4 and 0.75 kilowatts. That is well below the 1,200 to 1,800 watts printed on most labels.

So the quick rule you see everywhere (watts times hours, divided by 1,000) gives you a ceiling, not a bill. Which? makes the same point: the formula assumes the appliance runs at full power the whole time, and most do not.

What it costs per meal

Here are the Which? lab results, where the same foods were cooked in an air fryer and a built-in electric oven and the electricity was metered. We converted the energy figures into US costs at 18.83 cents per kWh, the April 2026 national average residential rate from the U.S. Energy Information Administration as reported by Newsweek.

The air fryer used between about a third and a half of the oven's energy every time. It also finished each food 10 to 23 minutes sooner.

An Australian test from the consumer group CHOICE landed in the same place. One of their writers cooked three everyday meals both ways, including sausages with roast vegetables and a family-size frozen apple pie, and found the air fryer cost roughly a third as much each time. CHOICE was careful to call those numbers estimates, since they came from a home smart meter app rather than lab equipment, and the oven was an older model.

Two independent tests, two countries, the same direction. That is about as solid as this kind of evidence gets.

Where the savings come from

It is tempting to think the air fryer is a miracle of efficiency. It mostly isn't. It wins on three ordinary things.

It heats a much smaller box. A full oven has to warm a big insulated cavity and a lot of metal before it does anything useful to your food. A 4 to 6 quart basket is a fraction of that space.

It skips most of the preheat. Which? included preheating in its figures, and CHOICE noted its oven needed 15 minutes of preheat before the apple pie went in. Most air fryers need a few minutes or none.

It cooks faster. Because the fan pushes hot air hard and close to the food, cook times drop. Less time running is less energy, regardless of wattage.

None of those advantages depend on the brand, which is useful to know when you shop. A pricier air fryer will not run noticeably cheaper than a basic one of the same size.

What it adds up to over a year

Per meal, the savings are pennies. Over a year they become real, if modest.

Averaging the four Which? foods, the air fryer saved about 0.59 kWh per cook compared with the oven. Say you use it four times a week instead of the oven. That is 208 cooks and about 123 kWh a year. Here is what that is worth at different rates:

Those state figures also come from the April 2026 EIA data reported by Newsweek. Your exact rate is on your bill, usually listed as a price per kWh. Multiply 123 by that number (in dollars) and you have your own estimate.

At the national average, a $100 air fryer takes around four years to pay for itself on energy alone. In a high-rate state it is closer to two. Most people do not buy one for the power bill, though. They buy it for crisp food in 20 minutes, and the lower bill is a side benefit. If you are still on the fence about the whole idea, our honest look at whether air fryers are worth it covers the cooking side.

When the air fryer does not save you money

Cooking in batches

This is the big one. The basket is small, and an overstuffed basket cooks unevenly. Which? found that the air fryer's manufacturer advised no more than 500 g of fries at a time, and only one baked potato fit.

Run the numbers on fries. One air fryer load used 0.287 kWh. Two loads use about 0.57 kWh, still less than the oven's 0.863. Three loads use about 0.86 kWh, which is the same as the oven, and you have been standing at the counter for over an hour. If you regularly feed four or more, the oven or a bigger appliance makes more sense. A dual-basket air fryer helps here because both baskets run at once, and an air fryer toaster oven is another option, which we compare in air fryer vs toaster oven.

Quick jobs, where the microwave keeps up

For reheating, the two are close. By our arithmetic, a microwave drawing 1,200 watts from the wall for 5 minutes uses 0.1 kWh, about 2 cents at the US average. An air fryer averaging the 0.4 to 0.75 kilowatts seen in the Which? tests would use a similar amount over 8 to 10 minutes. The microwave wins outright on soups, drinks, and defrosting, where it is done in a minute or two. For leftover pizza or fries the air fryer costs about the same and gives you crisp instead of limp.

A full roast dinner

Which? pointed out that a whole roast dinner can be cheaper in the oven, since the meat, potatoes, and vegetables cook at the same time on one heat source. Splitting that across an air fryer in several rounds wipes out the gain.

If your oven runs on gas

In the UK, Uswitch notes that a gas oven is cheaper to run than an air fryer, because gas costs much less per unit of energy there than electricity does. In the US the answer depends on your local prices for both, and it varies a lot by state. To compare, find your oven's Btu rating (on the label inside the door or in the manual). Divide it by 100,000 to get therms per hour at full flame, then multiply by your gas price per therm from your bill. Like an electric oven, a gas oven cycles its burner, so that figure is a ceiling too. A gas oven also has a long preheat, which still counts against it for small meals.

How to cut your air fryer's power use further

The appliance is already efficient. These habits squeeze a little more out of it, and most of them make the food better too.

1. Skip preheat when the recipe allows. Frozen foods are usually fine going straight in. Add a minute or two to the cook time instead. 2. Do not open the basket constantly. A quick shake halfway is enough. Every pull lets the heat out and the element has to work to recover. 3. Fill one layer, not three. An overloaded basket takes longer and cooks unevenly. Our guide to air fryer mistakes beginners make covers why spacing matters. 4. Use the oven when you are cooking a lot. Picking the right appliance for the size of the meal saves more than any setting. 5. Keep it clean. Grease on the element and fan burns off as smoke every time you cook. Our air fryer cleaning guide has the quick routine. 6. Convert oven recipes properly. Most oven recipes run hotter and longer than the air fryer needs. Use our oven to air fryer conversion rule so you are not overcooking and overspending.

Want to measure your own?

If you want exact numbers for your kitchen rather than averages from a lab, a plug-in electricity usage monitor will tell you. You plug it into the wall, plug the air fryer into it, and it reads out kWh used over a full cook, preheat and cycling included.

• What it does: Shows the live watts an appliance is drawing and the total kWh used since you plugged it in.
• Price: Retail listings we found in October 2026 mostly ran from about $25 to $35.
• Pros: Simple, no app or account needed; works on any plug-in appliance, so it is just as useful for a space heater or an old fridge.
• Cons: No phone app or history; it reads one appliance at a time.
• Skip if: You already have a smart meter app from your utility that shows usage by the hour. Run the air fryer alone and you can see the bump.

Does a bigger air fryer use more electricity?

Somewhat. Larger models usually carry higher wattage ratings, and a bigger basket takes a little more energy to heat. Two popular models show the range:

The hourly figures are worst-case ceilings at 18.83 cents per kWh. Real use is lower because the element cycles, and most cooks take well under an hour. In practice the difference between these two is a cent or two per meal, which is not a reason to choose one over the other. Size matters far more. A basket that fits your whole meal in one go will save more electricity than a lower wattage rating, because it saves you a second batch.

FAQ

How much electricity does an air fryer use per hour?

At full power, a 1,500-watt model would use 1.5 kWh in an hour. In real cooking it uses much less, because the heating element switches on and off once it reaches temperature. Metered Which? tests worked out to roughly 0.4 to 0.75 kWh per hour of cooking.

How much does it cost to run an air fryer?

About 4 to 10 cents per meal at the April 2026 US average of 18.83 cents per kWh, based on the Which? test foods. In high-rate states like California or Hawaii, double or more than double that.

Does an air fryer use more electricity than a microwave?

For a quick reheat they use about the same, around 2 cents at average US rates. The microwave uses less for soups, drinks, and defrosting because it finishes in a minute or two. The air fryer is the better choice when you want something crisp.

Is it cheaper to use an air fryer or the oven?

For small meals, the air fryer, typically using a third to a half of the oven's energy. For big meals that need several air fryer batches, the oven can come out even or ahead.

Does leaving an air fryer plugged in use electricity?

Models with a digital display may draw a very small amount while idle to keep the controls ready. We could not find reliable measurements for specific models, so if it bothers you, unplug it or use a switched power strip.

Can an air fryer trip a circuit breaker?

It can if it shares a circuit with another high-wattage appliance like a kettle, toaster, or microwave running at the same time. Plug it straight into a wall outlet rather than an extension cord, and avoid running two big kitchen appliances on the same circuit.

Do air fryers save money on a gas stove household?

Less clearly. It depends on your local gas and electricity prices. Gas ovens cost less to run in places where gas is cheap per unit of energy, but their long preheat still makes them wasteful for a single portion.

EggBoo Verdict: No, an air fryer does not use a lot of electricity. At US average prices most meals cost under a dime, roughly a third to a half of what the same small meal costs in an electric oven. The saving is real and small, around $20 to $60 a year for a regular user. Buy one because it cooks the food you eat quickly and well. Treat the lower power bill as a bonus, and keep using the oven when you are feeding a crowd.
