How much does an electric oven cost to run?
This worked example uses 2,400 W, 1 hours on each use day and 182 use days per year. Change any of these inputs in the calculator.
437 kWh/year · 2.40 kWh per use day
Electricity-price sensitivity
| Electricity price | Energy/use day | Annual energy | Annual cost |
|---|---|---|---|
| 15p/kWh | 2.40 kWh/day when used | 437 kWh/year | £66/yr |
| 25p/kWh | 2.40 kWh/day when used | 437 kWh/year | £109/yr |
| 35p/kWh | 2.40 kWh/day when used | 437 kWh/year | £153/yr |
Important assumption
Ovens cycle their heating elements, so 2.4 kW continuous for one hour is deliberately conservative as a simple worked example.
What changes electric oven electricity use?
An oven heats at high power initially and then cycles to maintain temperature. Pre-heating time, temperature, fan mode, door opening and the amount of food being cooked all affect total kWh. Using the full rated power for the full cooking time is usually a conservative simplification.
Make this estimate more realistic
For purchase or behaviour comparisons, use a kWh-per-cook figure if available. Batch cooking can make a full oven efficient per portion, while heating it for a single small item may be less efficient than a smaller appliance. Model the cooking pattern you actually use.
Electricity prices change, so the 15p, 25p and 35p/kWh rows are sensitivity examples rather than a current-tariff claim. Use the linked calculator with the unit rate shown on your own bill before relying on the annual cost.
