Air Fryer Electricity Cost: What It Really Costs to Run
An air fryer almost always costs less to run than a full-size oven for the same meal, because it draws fewer watts and cooks for less time with no preheat. The exact number depends on your air fryer’s wattage and your local electricity rate, but the math takes thirty seconds once you know where to look.
The quick answer
Multiply your air fryer’s wattage by the hours you run it, divide by 1000 to get kilowatt-hours, then multiply by your electricity rate per kWh from your utility bill. Most air fryers use 1200 to 1800 watts and run for 10 to 20 minutes, which usually costs a few cents a session, well under what the same meal costs in a full-size oven that draws 2000 to 5000 watts and needs a preheat.
Key takeaways
- Air fryers typically draw 1200 to 1800 watts, while full-size electric ovens typically draw 2000 to 5000 watts, so the wattage gap alone favors the air fryer before you even factor in cook time (air fryer definition from University of Nebraska-Lincoln Extension).
- Cook time matters as much as wattage. A quick air fryer session (10 to 20 minutes, often no preheat) uses far less total energy than an oven cycle that includes a 10 to 15 minute preheat plus a longer cook time.
- The real formula is wattage times hours divided by 1000, times your rate. That gives you kilowatt-hours, then dollars, using the rate printed on your own utility bill rather than a national average.
- The US average residential electricity rate sits around 19 cents per kWh, but rates vary a lot by state, from roughly 12 cents in cheaper states to well over 40 cents in the priciest ones (per the U.S. Energy Information Administration), so your own bill is the only number that gives you an accurate cost.
- Basket capacity is not the same as running cost. A bigger air fryer doesn’t automatically use more electricity per minute, since wattage and capacity don’t scale together in a fixed ratio.
The formula: wattage, time, and your actual rate
The math behind any appliance’s electricity cost is the same three steps every time. First, find the wattage on the rating label, usually on the bottom or back of the unit. Second, convert watts to kilowatts by dividing by 1000, then multiply by the hours you run it to get kilowatt-hours (kWh). Third, multiply that kWh figure by your electricity rate in cents per kWh, which you’ll find on your utility bill, not a national estimate. That last step is the one people skip, and it’s the one that actually decides your real number, since rates differ a lot depending on where you live.
As a worked example: a 1500-watt air fryer running for 30 minutes uses 1500 × 0.5 ÷ 1000 = 0.75 kWh. At the US average residential rate of roughly 19 cents per kWh, that’s a little over a dime. Swap in your own bill’s rate for an exact figure.
Air fryer vs. oven: side-by-side estimate
Here’s how a typical weeknight cook compares, using commonly cited wattage ranges and a 30-minute cook window for both appliances:
| Air fryer | Full-size oven | |
|---|---|---|
| Typical wattage | 1200 to 1800W | 2000 to 5000W |
| Typical cook time | 10 to 20 min, often no preheat | 30 to 45 min, plus a 10 to 15 min preheat |
| Rough energy per session | About 0.3 to 0.6 kWh | About 1.5 to 3 kWh |
| Rough cost at ~19 cents/kWh | Roughly 6 to 11 cents | Roughly 28 to 57 cents |
These are ballpark ranges based on commonly reported appliance wattages, not a lab measurement of any single model, so treat them as a starting point and run the formula above with your own air fryer’s label and your own utility rate for a real number.
Why the gap is bigger than the wattage alone suggests
The wattage difference is only part of the story. An oven also has to preheat before it starts cooking, which burns electricity before any food goes in, and a full-size cavity has to heat all that empty air along with your food. An air fryer’s smaller chamber heats up almost instantly and usually needs no preheat step at all for most recipes, so you’re not paying for wasted warm-up time. That’s why the real-world gap between the two often ends up bigger than just comparing the watts on each label.
Want the exact number instead of an estimate?
The formula above gets you a solid estimate, but if you want to see the real number for your specific unit and your specific cooking habits, a simple plug-in energy usage monitor (the kind that sits between the wall outlet and the appliance) reads the exact watts your air fryer draws in real time and tracks total kWh over a week or a month. It’s a cheap, one-time way to confirm your estimate rather than a requirement, since the math above already gets most people close enough to make a buying decision. If you’re still shopping for the appliance itself, the Cosori 9-in-1 TurboBlaze 6Qt tops our best air-fryers in the USA guide and lists its wattage right on the product page, so you can run the formula before you even own one.
Bottom line
An air fryer almost always costs less to run than a full-size oven for a comparable meal, thanks to lower wattage, shorter cook times, and no preheat step. Do the actual math with your air fryer’s wattage label and your own utility rate rather than relying on a single national number, since rates vary a lot by state.

Frequently asked questions
How much electricity does an air fryer use per session?
Most air fryers are rated between 1200 and 1800 watts, and a typical weeknight cook runs 10 to 20 minutes with no preheat. Multiply the wattage by the hours it runs and divide by 1000 to get kilowatt-hours, then multiply by your rate per kWh from your utility bill. A 1500-watt air fryer running 20 minutes uses roughly 0.5 kWh, which is only a few cents at the US average residential rate.
Is an air fryer cheaper to run than an oven?
For most weeknight meals, yes. A full-size electric oven typically draws 2000 to 5000 watts and needs a preheat plus a longer cook time, while an air fryer draws less power and often skips preheating altogether. Cooking the same portion of food in an air fryer instead of a full oven cycle usually costs a fraction as much in electricity, though the exact gap depends on your oven's wattage and how long you'd otherwise run it.
How do I calculate my exact air fryer electricity cost?
Find the wattage on the rating label on the bottom or back of the unit, convert it to kilowatts by dividing by 1000, multiply by the hours you actually run it, then multiply that number by your electricity rate in cents per kWh from your utility bill (not a national average, since rates vary a lot by state). That gives you the real cost per cook, not just an estimate.
Does a bigger air fryer basket cost more to run?
Not necessarily. Basket size mostly affects how much food fits in one batch, not the wattage. A larger-capacity air fryer can sometimes carry a slightly higher wattage rating, but the bigger cost driver is how long you run it and how often you're cooking two smaller batches instead of one full one. Check the wattage on the label rather than assuming capacity and cost scale together.
