Electricity cost calculator
Find out what any device costs to run. Enter its power in watts (on the label or in the manual), how long it runs each day, and your country or your own price per kWh.
Calculate your cost
Leave empty to use the official price for United States: 18.16¢/kWh (August 2026).
Tariff and voltage
At 120 V it draws about 8.3 A. Voltage changes the current (amps), not the cost.

1 kWh per hour · 3 kWh per day
Based on 1,000 W for 3 h a day, 30.4 days a month, at 18.16¢/kWh.
On slab (tiered) tariffs, use the price of the highest slab your bill reaches: that's what each extra unit really costs.
How the calculation works
Energy (kWh) = watts × hours ÷ 1,000. A 1,000 W device running for one hour uses exactly 1 kWh, the unit on your bill.
Cost = kWh × price per kWh. A month here is 30.4 days and a year is 365 days.
Appliances with a thermostat or compressor, such as fridges, heaters and air conditioners, switch on and off, so their real use is usually lower than watts × hours. The appliance guides account for this.
Where to find the watts
Check the label on the back or bottom of the appliance, or the charger. If it shows amps and volts instead, watts ≈ volts × amps.
For the most accurate number, a plug-in energy meter measures what the device really uses.
