How Much Does It Cost to Run a Ceiling Fan? (2026)

Ceiling fans do not cool the air, they cool people through air movement. At 15 to 90 watts they cost a tiny fraction of an air conditioner, which is why the best strategy is to run both and raise the AC thermostat.

A typical ceiling fan (50 W) costs $0.009 per hour, or about $2.16 per month at 8 hours a day in United States (average). Cheap to run

Low (15 W)$0.003$0.022$0.65$7.88
Typical (50 W)$0.009$0.072$2.16$26.28
High (90 W)$0.016$0.13$3.89$47.30

Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 146 kWh per year.
