Calculate your cost
Start with a representative input, then edit all three numbers.
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 |
| Starting point | 1 | $13.56 |
| Longer runtime | 1.5 | $20.34 |
Same 2,400-watt input and 18.83¢/kWh rate; only runtime changes.
The quick formula
2.4 kW × 1 hours × $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 preheating and then cycles its elements to hold temperature. A short bake at moderate heat costs less than treating the full rated wattage as continuous for the entire cooking period.
The starting values keep this page useful before you have a label or meter reading. They do not describe every model, climate, operating mode, or household.
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.
