Ceiling Fan Electricity Cost Calculator
Estimate ceiling-fan electricity cost by speed, daily hours, number of fans, and local rate.
Calculate ceiling-fan running cost
How this calculator works
A ceiling fan moves air but does not lower room temperature. It can improve comfort for people in the room and may allow a higher air-conditioner thermostat setting.
Fan watts vary by speed, motor design, light kit, and model. Enter motor power only unless you also want to include attached lighting.
Two 45-watt fans running 10 hours per day at $0.18/kWh cost about $0.16 per day and $4.86 per month.
How to get a more accurate estimate
- Use watts for the speed setting you actually use.
- Turn fans off in unoccupied rooms because the comfort effect is primarily for people.
- Calculate an attached light separately when its wattage is not included.
Frequently asked questions
Does a ceiling fan cool the room?
It creates air movement that can make occupants feel cooler but does not remove heat like air conditioning.
Can a fan reduce AC cost?
It may help if the added comfort lets you raise the thermostat, but savings depend on behavior and climate.
Are DC-motor fans cheaper to run?
Efficient DC-motor models can use less power at comparable airflow, but check product data for the specific model.
Results use the values you enter and the formula shown above. Real bills can include taxes, minimum charges, tiers, time-of-use pricing, cycling losses, and other adjustments. Use a recent bill or a plug-in energy meter when accuracy matters.
