Calculate your cost
Start with a representative input, then edit all three numbers.
This setup uses about 14 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 4 | $1.36 |
| Starting point | 8 | $2.71 |
| Longer runtime | 12 | $4.07 |
Same 60-watt input and 18.83¢/kWh rate; only runtime changes.
The quick formula
0.06 kW × 8 hours × $0.1883 = $0.09 per day
Convert watts to kilowatts, multiply by the active hours used each day, then multiply by the electricity price in dollars per kWh. Multiply the daily result by 30 for the monthly estimate shown above.
How to read this estimate
A ceiling fan uses far less electricity than compressor-based cooling and can improve comfort in an occupied room. It cools people through air movement rather than lowering room temperature, so running it in an empty room provides little benefit.
The starting values keep this page useful before you have a label or meter reading. They do not describe every model, climate, operating mode, or household.
What changes the cost?
- 01
Motor type, fan diameter, and selected speed
- 02
Hours used and number of fans operating
- 03
Integrated light wattage, if the fixture includes one
Ways to spend less
- Switch the fan off when the room is empty.
- Use the lowest speed that maintains comfort.
- Raise the air-conditioning setpoint when the fan makes that comfortable.
