Electricity Cost Calculator
Estimate how much an appliance costs to run. Enter the power in watts, hours used per day, electricity rate and days per month to see daily, monthly and yearly costs.
How It Works & Formula
Daily energy is (watts x hours) / 1000 kWh. Daily cost is kWh x rate, and monthly cost is daily cost x days per month.

A kilowatt-hour is the energy used by a 1000-watt appliance running for one hour, and it is the unit on your electricity bill.
