Estimate a home appliance’s electricity cost

Watts measure demand. Energy (kWh) = (W × hours) ÷ 1000.

Approx cost = kWh × your bill’s kWh price (plus standing charges and taxes on a real bill).

Fridges draw little power for many hours; ovens draw a lot briefly. Consider both.

Our electricity calculator gives a quick estimate. Check your supplier and time-of-use rates for the real bill.

LEDs and cutting standby often save more over a year than people expect.
