Calculate your cost
Start with the example below, then replace the wattage, daily runtime, and rate with the numbers for your electric oven.
This setup uses about 72 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 0.5 | $6.78 |
| Page example | 1 | $13.56 |
| Longer runtime | 1.5 | $20.34 |
Same 2,400-watt input and 18.83¢/kWh rate; only runtime changes.
Formula for the page example
2.4 kW × 1 hr × $0.1883 = $0.45 per day
Convert watts to kilowatts, multiply by the active hours used each day, then multiply by the electricity price in dollars per kWh. Multiply the daily result by 30 for the monthly estimate shown above.
How to read this estimate
An electric oven draws heavily while it preheats, then cycles the elements to maintain temperature. It will not normally use its full rated wattage for every minute of a bake, especially during a shorter cooking session.
Use this as a baseline until you can check the label or measure the electric oven directly. Model, settings, condition, climate, and household routine can all change the result.
What changes the cost?
- 01
Set temperature, preheat time, and cooking duration
- 02
Oven size, insulation, door seal, and element cycling
- 03
Convection use and number of dishes cooked together
Ways to spend less
- Cook multiple dishes together when temperatures are compatible.
- Avoid opening the door repeatedly during cooking.
- Use a microwave or smaller appliance for short, small portions.
