Appliance Running Cost Calculator (USA)

See what a single appliance costs to run per hour, day, month and year — including standby draw. Then compare it against an efficient replacement to find the payback period and lifetime savings.

For estimation purposes only. Nameplate wattage is a maximum — real draw cycles with thermostats, loads and settings. Check the yellow EnergyGuide label for rated annual use.
