How it works
Multiply the oven's power by the hours it runs to get the energy used, in kilowatt-hours. Then multiply that by your price per kilowatt-hour.
Your electric bill lists the price per kilowatt-hour, and the oven's rating is usually on its label or in the manual. Elements cycle on and off, so real use is often below the full rating.
Worked example
A 8,000 BTU/h oven running for 1.5 h uses 3.52 kilowatt-hours, which costs $0.56 at $0.16 per kilowatt-hour.
Questions
Is my bill price the same as this rate?
Often not. Bills add fixed charges and taxes, so use the energy charge per kilowatt-hour for the closest estimate.
Does preheating add much?
Preheating runs the elements at full power, so it counts toward the total. It is usually a small share of a longer bake.
Why is the estimate higher than my bill shows?
A thermostat switches the elements off once the set heat is reached, so an oven rarely draws its full rating the whole time.
