How Much Electricity Does an Air Fryer Use? Real Cost (2026)

How much electricity does an air fryer really use?

Whatever your utility charges, it's worth knowing what each kitchen appliance actually costs to run. The good news: despite a high wattage on the label, an air fryer uses very little electricity in practice, roughly 0.3 to 0.5 kWh per session. That's about 6 to 10 cents per batch at our example rate.

How we calculate: every cost example in this guide uses an example rate of 20 cents per kWh. Rates vary widely by state and utility, so check the rate on your utility bill; yours may be higher or lower. To get your real cost, just multiply the kWh figures by your price per kWh.

Rated wattage isn't actual consumption

The most common mistake is reading the wattage (e.g., 1,700 W) and assuming the air fryer uses 1.7 kWh every hour. The wattage only tells you the maximum draw of the heating element at full power.

The element heats in cycles: it shuts off once the target temperature is reached and kicks back on when the temperature drops. Over a typical cook, it's only running 50% to 70% of the time. And most dishes are done in 12 to 25 minutes, not a full hour.

• kWh = (watts ÷ 1,000) × hours × duty cycle
• Example: 1,700 W ÷ 1,000 = 1.7 kW × 0.25 hr × 0.7 = ≈ 0.30 kWh

It also helps to separate the heat-up phase from the cooking phase. For the first few minutes, the air fryer draws its full wattage to get up to temperature fast. After that, consumption drops sharply, because the element only has to maintain the heat. In a 20-minute cook, only three to five minutes fall in that energy-hungry heat-up phase. If you want your exact number, a plug-in electricity usage monitor between the outlet and the air fryer shows the kWh used in real time.

Estimated use per session (duty cycle of 0.7)

Yearly cost: 3 times a week vs. every day

Based on an average of 0.4 kWh per session and our example rate of 20 cents per kWh (0.4 kWh × number of sessions × $0.20).

Even with daily use, the yearly cost stays modest, at about $29. Three times a week comes to only about $12 in electricity a year.

Compared with a regular oven

This is where most of the savings come from. An oven has to heat a cavity of 2.1 to 2.5 cu ft (60 to 70 liters) and needs to preheat. An air fryer heats just 3.2 to 8.5 quarts (3 to 8 liters).

That means an air fryer uses 50% to 70% less electricity than an oven for the same amount of food. More in our guide to air fryer energy savings.

Compared with a deep fryer

A deep fryer has to heat roughly 2 to 4 quarts (2 to 4 liters) of oil and hold it at 340 to 350°F (170 to 180°C).

• Deep fryer: ≈ 0.6 to 0.8 kWh per session.
• Air fryer: ≈ 0.3 to 0.5 kWh per session.

On top of that, you have the ongoing cost of oil that needs replacing regularly. See our air fryer vs. deep fryer comparison.

Tips to cut your energy use even more

• Skip unnecessary preheating: it's often not needed, especially for frozen foods.
• Cook in full batches: one well-filled basket is more efficient than two small batches.
• Use a dual-basket model: cook the main and the side at the same time.
• Clean it regularly: a dirty air fryer can use 10% to 15% more energy.
• Use leftover heat: cook back to back while the air fryer is still hot.

Energy use for everyday dishes

Here are realistic estimates for common dishes at our example rate of 20 cents per kWh:

For reheating or cooking small amounts, nothing beats an air fryer: turning on the oven would be pure waste. Over a year, it's these small, frequent cooks that create the biggest savings compared with the oven.

Smart air fryers: keeping tabs on energy use

Many air fryers now connect to Wi-Fi and work with an app. That can help with energy use: precise temperature and time settings keep you from cooking longer than you need to. On the other hand, a smart model with a display and a Wi-Fi module draws 1 to 3 watts on standby around the clock, roughly 9 to 26 kWh a year (about $2 to $5 at our example rate), whether you cook or not. A power strip with an on/off switch or a smart plug fixes that by cutting power completely after use.

The most efficient models and the EU energy label

Models from Xiaomi and Cosori strike a great balance of wattage, cook time and energy use (for example, the Cosori Lite 3.8L at 1,500 W or the Xiaomi Smart Air Fryer Pro 4L at 1,600 W, at around 0.32 to 0.34 kWh for 18 minutes). Note that there's no dedicated, mandatory EU energy efficiency class for air fryers yet, unlike refrigerators or washing machines, so go by wattage, capacity and independent real-world measurements. As a rule, a more moderate wattage paired with enough capacity is a good sign of efficiency. Models sold in Europe are built for 230 V; check that the version on your Amazon store is rated for 120 V. See our picks in our roundup of the best budget air fryers.

The bottom line

Even where electricity is expensive, an air fryer is one of the cheapest ways to cook small and medium portions: around 0.3 to 0.5 kWh per session and a modest yearly cost (about $12 at three uses a week, at our example rate).

Don't let the high wattage on the label scare you off. What matters is the actual energy used in kWh, and it stays low thanks to short cook times, a small cavity and little to no preheating. Choose an efficient model and follow a few simple habits, and you'll keep your electricity costs to a minimum for years to come.
