Electricity Cost Calculator

Use the appliance’s rated electrical input, your expected hours of use and the energy rate on your bill.

Enter your details

Use electrical input power from the label or a measured average.
Enter a non-negative rate; zero is allowed. The amount is in the selected currency.
Labels amounts only; no exchange-rate conversion is performed.

How the estimate works

Daily kWh = (watts ÷ 1,000) × hours per day. Monthly kWh = daily kWh × days. Cost = kWh × your rate.

Assumptions and limits

This estimate assumes the appliance draws its entered power while running. Taxes, fixed charges and other fees are excluded unless included in your rate.

Example

A 1,000 W appliance used 2 hours a day for 30 days uses 60 kWh. At 0.20 per kWh, the estimated monthly energy charge is 12.00 in the selected currency.
