Ceiling Fan running cost calculator

These are estimates, not certified measurements.

Wattage range reflects the measured low/high-speed power of ENERGY STAR certified ceiling fans (the certification covers airflow efficiency in CFM/W, not annual kWh).

Ceiling fans are among the cheapest devices in the house to run — the question is almost never the fan, it's whether it lets you raise the thermostat.
