How it works

Daily cost = watts ÷ 1000 × hours per day × rate. Monthly = daily × 30.4. Seasonal cost = daily × days used per year. Even running all night, a fan typically costs a few cents — far less than air conditioning.

Frequently asked questions

Is a fan cheaper than AC?

Dramatically — a fan might use 50 W while an AC unit uses 1,000+ W. For mild heat, a fan can cost 1–2% of running AC.

Does a fan actually cool a room?

It cools you, not the room, by helping sweat evaporate. Turn it off when you leave to avoid wasting power.

Tower vs pedestal vs ceiling?

Power and effectiveness vary, but all are cheap. Ceiling fans are efficient for whole-room air movement; check the wattage on yours.
