Preheat is the tax
Preheating spends full element power with zero food inside. Two back-to-back bakes cost barely more than one — batch your oven work.

Preheating spends full element power with nothing in the cavity, and opening the door makes the oven pay to rebuild the heat it lost. Set your baking hours and state below to see the cost.

Run like this for a year and it adds about $160 to your electricity bill.
The element cycles on/off to hold temperature, so average draw is below nameplate (3,000–4,000 W peaks). We model the cycling average.
Energy: 2.4 kWh per day · 876 kWh per year, at 18.31¢/kWh (U.S. average).
How many watts does an electric oven use, and what does it cost to run?
Wattage is the number that decides everything else. The table below runs the actual figures through this page's calculator at the U.S. average rate of 18.31¢ /kWh, so you can see the running cost jump as the load climbs. Change any value above and the whole page recalculates.
| Watts | Power draw | Per hour | Per month (1 h/day) |
|---|---|---|---|
| 1,500 W | 1,500 W draws 1.50 kW | $0.27 | $8.35 |
| 2,335 W | 2,335 W draws 2.33 kW | $0.43 | $13.01 |
| 3,165 W | 3,165 W draws 3.17 kW | $0.58 | $17.63 |
| 4,000 W | 4,000 W draws 4.00 kW | $0.73 | $22.28 |

What changes the number
Peeking costs
Every door opening dumps a chunk of heat; the element pays to rebuild it. The light and window exist for a reason.
Convection saves
Convection mode moves hot air onto the food, typically cutting cook time or temperature requirement — a real 10–20% saving on the same dish.
Cut the cost
Biggest savings first.
- Skip preheat for roasts and casseroles; it matters most for baked goods.
- For dishes where it is appropriate, you can switch the oven off shortly before the timer ends and use residual heat. Check that food reaches its recipe's safe internal temperature.
- Batch-bake: two trays or back-to-back dishes cost little more than one.
- Reheat single portions in the microwave or air fryer, not the full oven.
Frequently asked questions
How much does it cost to run an electric oven for 1 hour?
About 30–60¢ at the U.S. average rate (18.31¢/kWh) depending on how hard the element cycles — roughly 44¢ for a typical bake.
How much does it cost to bake a cake?
A 40-minute bake plus preheat is about 0.8–1 kWh, so roughly 15–20¢ at the U.S. average rate. The energy is small; the oven's real cost is time, not money.
Is it cheaper to cook with gas or electric oven?
In most states gas heat costs less per unit than electric resistance, though electric ovens are slightly more efficient at converting energy to food heat. For most households the operating difference is a few dollars a month.
