Air fryer
How much electricity does an air fryer use?
1,400–1,800 W · 10–20 min per use · under $3 per month
Air fryers have become the most-searched kitchen appliance of the decade, and the energy question follows. The answer is simple: high power, short time, small cavity.
Air fryer vs oven
A full-size electric oven draws 2,000–5,000 W and needs 10–15 minutes of preheating plus 20–40 minutes of cooking. An air fryer draws 1,400–1,800 W, needs 2–3 minutes to come to temperature, and cooks in 10–20 minutes.
For the same portion of food, the air fryer typically uses 0.3–0.5 kWh against the oven's 1.2–2.0 kWh. If you use it instead of the oven three times a week, that is roughly $30–50 a year.
When the oven still wins
Cooking for a family of five, or a full tray of food, the air fryer's small basket means batch after batch — and the oven becomes the better choice. The air fryer's advantage is scale-dependent.
Getting the most from it
- Don't preheat longer than 2–3 minutes. The cavity is tiny; it heats almost instantly.
- Fill the basket but don't crowd it. Overfilling blocks air circulation and extends cooking time.
- Turn it off a minute early. The residual heat finishes most foods, and the element is not cycling.
Frequently asked questions
How many watts does a air fryer use?
1,400–1,800 W. The figure on the rating label is the maximum draw; actual use varies with settings, age and usage pattern.
How much does it cost to run a air fryer per month?
With the defaults above it comes to the monthly figure shown in the calculator. At 16.5¢/kWh — the US residential average — that is a realistic middle estimate. Your own bill may be 30% lower or higher depending on state.
Is it cheaper to run a air fryer at night?
Only if your utility offers a time-of-use plan and you avoid the 4pm–9pm peak window. On a flat-rate plan, the time of day makes no difference to the total.
Does the calculator account for real-world duty cycles?
Not automatically — you enter the effective hours yourself. For compressing appliances like refrigerators and AC units, enter the running watts and roughly the proportion of time the compressor is on, which is usually 30–50%.
Will a newer air fryer actually save money?
Compare the kWh figure in the calculator against an Energy Star model's stated annual use. If the difference is a few hundred kWh a year, the payback on a replacement is usually long; if it is over 500 kWh, it is worth pricing out.
