Ceiling Fan Electricity Cost Calculator

See how little a fan costs to run, and how much a BLDC (DC motor) fan saves over an older model.

Quick answer

A 60 W ceiling fan costs about 1¢ an hour at $0.17/kWh — roughly $3 a month at 10 hours a day. That is a small fraction of what an air conditioner costs for the same hours.

About the Ceiling Fan Electricity Cost calculator

Conventional ceiling fans with AC induction motors draw about 50–90 W on high. Energy-efficient BLDC (brushless DC) fans draw 25–35 W for similar airflow. Pedestal and table fans range from 20 to 60 W.

Fans don’t cool the air — they make you feel 2–4 °C cooler through evaporation. Running a fan alongside an AC lets you set the thermostat higher, which saves far more than the fan costs.

Try the calculator with 60 W, then with 30 W, to see what a BLDC upgrade saves per fan per year.

How to use it

  1. Enter the fan wattage on the speed you normally use.
  2. Enter hours per day.
  3. Keep load at 100% — fans don’t cycle.
  4. Enter the number of fans if you want a household total.

The formula

Monthly cost = Watts × Hours × Fans ÷ 1000 × 30 × Price

Worked example

A 60 W fan running 10 hours a day

  1. 60 × 10 = 600 Wh = 0.6 kWh per day.
  2. At $0.17/kWh: about $0.10 per day.
  3. About $3.06 per month.

Frequently asked questions

Does fan speed affect electricity use?

Yes. On lower speeds a fan draws noticeably less power — often half or less of its top-speed rating.

Is a BLDC fan worth it?

If the fan runs many hours a day, yes. Saving 30 W over 12 hours a day is about 130 kWh a year per fan.

Fan or AC — which is cheaper?

A fan uses a tiny fraction of an AC’s power — roughly 50 W versus 1,000 W or more.
