What changes the cost of a ceiling fan?
The quick answer is power multiplied by time and your electricity rate—but the right input depends on the appliance. Wattwise starts this calculator with a representative estimate, not a manufacturer-specific claim. Replace defaults with measured, label, or bill values wherever possible.
- Motor type and speed setting
- Number of fans
- Nightly runtime
- Remote-control standby
- Cooling-season months
Example ceiling fan running costs
These examples use United Kingdom unit rate and the typical schedule shown in the calculator. Electricity tariffs vary by provider, tier, time, tax, and subsidy, so replace the rate with the value on your bill.
| Example | Energy input | Indicative cost |
|---|---|---|
| BLDC fan | 32 W | $0.01 / hour |
| Efficient induction | 55 W | $0.01 / hour |
| Older fan | 80 W | $0.02 / hour |
Ways to reduce this appliance’s electricity cost
Savings depend on comfort, safety, usage, and the equipment you already own. Model a change before buying a replacement, and verify high-cost appliances with a meter or label value.
- Compare BLDC models when a fan runs most nights.
- Turn off fans in empty rooms; fans cool people, not room air.
- Use a fan with a higher AC thermostat setting.
How Wattwise calculated this estimate
For the default inputs, Wattwise estimates $3.39 per month and 16.9 kWh at the global reference rate. The active formula is: average active power kW × operating hours × quantity, plus standby.
The displayed range widens when power, duty cycle, weather, or tariff data are estimates. It narrows when you provide measured energy, an official annual kWh value, or a per-cycle energy label. Fixed charges are not allocated to one appliance unless you explicitly create a household bill allocation.
