About ceiling fan running costs
Ceiling fans move air rather than cool it, so they cost only a few cents a day and let you raise the thermostat.
Typical sizes: 30 W, 60 W, 75 W, 100 W.
How to spend less: Switch the fan off when nobody is in the room. It cools people, not the space.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
