Appliance energy-cost calculator
Estimate electricity use from values you supply. Choose a power-and-runtime estimate or a measured/label kWh figure; the tool does not measure the appliance.
Your inputs
Enter 0.20 for 20 cents per kWh, not 20. Use a single representative rate; this is not a time-of-use tariff calculator.
The arithmetic, without the tool
Watts × powered hours per day × days ÷ 1,000 = kWh. Alternatively, kWh per cycle or period × number of cycles or periods = total kWh. Multiply total kWh by the variable rate per kWh for the estimated electricity charge.
Illustration only: 1,000 W × 2 powered hours/day × 30 days ÷ 1,000 = 60 kWh. At USD 0.20/kWh that is USD 12.00. This is not a typical-use claim for a particular appliance.
What the result leaves out
Standing charges, demand charges, time-varying rates, separate hot-water or gas consumption, maintenance and purchase costs are not included. No tariff or currency conversion is fetched. Different EnergyGuide labels may use different assumptions; compare equivalent periods and appliance sizes.
