Electric oven cost calculator
How Much Does an Electric Oven Cost to Run?
Estimate the electricity cost of using an electric oven from its power draw, cooking time, and your electricity price.
Cost estimate
Calculate your electricity cost
Estimated energy use0 kWh/day
Estimated monthly energy0 kWh/month
Cost = watts ÷ 1,000 × hours used × electricity price.
Example
How the starting estimate works
At 2,400 watts for one hour, the starting example uses 2.4 kWh before multiplying by your electricity price.
Real-world use
The elements cycle after preheating.
An oven's heating elements typically switch on and off to maintain temperature. Using the element rating for the full cooking time can therefore be a conservative estimate.
Preheating is only part of the cycle
Oven elements cycle after the cavity reaches temperature.
An electric oven may draw several kilowatts when one or more heating elements are energized, but the elements usually switch on and off to maintain the set temperature. Multiplying the full element rating by the entire cooking time can therefore overstate energy use.
Cooking temperature and duration
Longer cooking usually matters more than a short preheat.
A one-hour bake at a moderate temperature can use less energy than a multi-hour roast even if both preheat to the same temperature. Opening the door repeatedly lets heat escape and can trigger additional element runtime.
Convection and batch cooking
How you use the oven can change energy per meal.
Convection can sometimes shorten cooking time or allow a lower set temperature, depending on the food and recipe. Cooking several items during one heated session can also spread preheating energy over more food.
This calculator prices the electrical energy you specify; it does not model a particular oven's thermostat cycle. See How to Estimate an Appliance's Electricity Cost for the general method.
