Cost to run

How much does a ceiling fan cost to run?

Ceiling fans are among the cheapest comfort appliances in a home. A typical fan on medium speed draws less than a laptop charger, so even long daily runtimes cost little.

Fan speed changes watts dramatically

Airflow costs rise steeply with speed: a fan drawing seventy watts on high may use under twenty on low. If you mostly run lower speeds, entering the high-speed nameplate figure will overstate your real cost several-fold.

Fans cool people, not rooms

Moving air raises evaporative cooling from skin without lowering air temperature, so a fan only helps while someone is present. Pairing fans with a slightly higher air-conditioner setpoint is where the real bill savings come from, not from the fan itself.

Details outside the ceiling fan estimate

Light kits add their bulbs' wattage on top of the motor figure modeled here. DC-motor fans undercut AC motors at every speed, and winter reverse mode has the same electrical cost as forward operation at equal speed.

Frequently asked questions

Is it wasteful to leave ceiling fans on all day?

The direct cost is small, but a fan in an empty room provides no comfort benefit. Turning it off when leaving saves the entire, if modest, expense.

Do ceiling fans reduce air-conditioning costs?

Indirectly, yes. The breeze lets most people stay comfortable with the thermostat set a few degrees higher, and the AC savings usually exceed the fan's own consumption.

How many watts does my fan actually draw?

Check the specification label on top of the motor housing or the product listing. Energy-rated models publish airflow and watts at each speed, which map directly to this calculator.
