How the math works: 75 W × 8 hours ÷ 1,000 = 0.6 kWh a day. × 30 days = 18 kWh a month. × $0.165 per kWh (the 2024 U.S. average) = about $2.97 a month.
A ceiling fan typically draws just 65 to 175 watts, making it one of the cheapest appliances in the house to run. That's because a fan cools people, not the room itself, so it doesn't need to do nearly as much work as an air conditioner.
What affects how much electricity a ceiling fan uses
- Fan size and motor: larger blades and older, less efficient motors draw more power than a compact, modern DC-motor fan.
- Speed setting: running on high draws more than running on low.
- Who's in the room: a ceiling fan cools by moving air across skin, not by lowering the room's temperature, so it only helps while someone is there to feel the breeze.
How to reduce your ceiling fan's electricity use
- Turn the fan off when you leave the room, since it doesn't cool an empty room
- Run it on the lowest speed that still feels comfortable
- Switch the blade direction seasonally (counterclockwise in summer, clockwise in winter) to work with your heating and cooling rather than against it
- Consider a DC-motor fan when replacing an old one, since these typically use less power than older AC-motor models

A ceiling fan cools people, not rooms, so it draws far less than air conditioning and only helps while someone's actually in the room to feel the breeze.

Frequently asked questions
How many watts does a ceiling fan use?
Most ceiling fans draw 65 to 175 watts, according to a DOE-developed appliance energy table reproduced by Virginia Cooperative Extension. That's far less than almost any cooling appliance, including a window air conditioner or dehumidifier.
How much does it cost to run a ceiling fan?
A 75-watt fan run 8 hours a day at the U.S. average rate of about 16.5 cents/kWh costs less than $0.10 a day, or roughly $3 a month. Use the calculator above with your own fan's wattage and rate for an exact figure.
Does running a ceiling fan actually lower the room temperature?
No. A fan doesn't cool the air itself, it moves air across your skin, which speeds up evaporation and makes you feel cooler. That's why it doesn't help an empty room and why pairing it with an air conditioner (raising the thermostat a few degrees while the fan runs) can save more than running either one alone.
How can I reduce how much electricity my ceiling fan uses?
Turn it off whenever you leave the room, since a fan running with nobody there wastes electricity with no benefit. Running it on a lower speed setting also helps, and switching the blade rotation direction seasonally makes it work more effectively year-round.
