What does an electric oven cost to run?

Run the numbers on your own use

Change any of these and the figures update. The defaults are the typical case described above; your rate is the input that moves the answer most.

Why this is lower than the number you will see elsewhere

Almost every published answer to this question multiplies the rating on the label by the hours the appliance is switched on. For an electric oven that gives 900 kWh a year, or $165.

The element is full-on during preheat and then cycles to hold temperature, which is most of the cooking time.

The arithmetic, step by step

Nothing here is hidden, so you can check it or change it. Working in the order the formula runs:

1. 3,000 W — what it draws while it is actually drawing. This is the rating on the plate.
2. × 35% — the share of its in-service time it is really pulling that. The element is full-on during preheat and then cycles to hold temperature, which is most of the cooking time.
   That gives 1050 W averaged across the hours it is on.
3. × 1 hours a day × 300 days — An hour of baking most days.
   1050 × 1 × 300 ÷ 1,000 = 315 kWh a year.
4. + standby — 3 W for the other 23.0 hours a day, which is 21 kWh a year. People leave this out and it is not always small.
5. × 18.34¢ — the US average residential rate for June 2026.
   336 kWh × 18.34¢ = $62 a year.

Change any assumption in the calculator above and every figure on this page moves with it. The two that matter most are your rate, which varies 4× across the country, and the hours — the duty cycle is a property of the appliance, but the hours are a property of you.

How sensitive is that number?

A single figure invites more confidence than it deserves. Here is the same appliance under assumptions either side of the default, so you can see how much of the answer is the appliance and how much is the guess about how you use it.

Everything else held at the default. The spread here is the honest error bar on the headline figure.

What it costs per hour, day and month

At 18.34¢ per kWh, the US residential average for June 2026.

The thing worth knowing

Preheating is the expensive part, because that is the only period the element runs flat out. For anything under about 30 minutes of cooking, a countertop oven or air fryer heats a much smaller box and wins easily.

Against air fryer

An air fryer or toaster oven for small portions; batch-baking to use one preheat for several dishes. In numbers: an electric oven costs $62 a year on these assumptions, and air fryer doing a comparable job costs $18 — a difference of $44 a year, or $440 over ten years at today’s rate.

Both at 18.34¢/kWh, each on its own standard usage assumption. Ten years is roughly the service life of either.

What it costs in your state

The appliance is the same everywhere; the rate is not. Running this electric oven costs $177 a year in Hawaii and $44 in Nevada — a difference of 4×.
