Why fans are usually inexpensive
Most portable fans use a small electric motor, so their wattage is much lower than appliances that create heat or run a compressor. Even long daily use often costs only a few cents compared with air conditioning.

This uses 60 watts, 8 hours per day, and an electricity rate of $0.17 per kWh.
Most household fans use far less electricity than air conditioners, even when running for many hours.
Typical fan wattage
Many fan units fall around 60 watts, with a rough range of 20 to 100 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 20W | 4 | $0.01 | $0.41 |
| Typical use | 60W | 8 | $0.08 | $2.45 |
| High estimate | 100W | 12 | $0.20 | $6.12 |
How the estimate works
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity RateFor this fan example: 60 / 1000 x 8 x 0.17 = $0.08 per day.

These details make this estimate more useful for real-world use.
Fans help most when people are present
A fan does not lower the room temperature by itself. It helps people feel cooler by moving air across skin, so the best savings come from using fans in occupied rooms and raising the air conditioner thermostat when comfortable.
How to lower the cost
Turn fans off in empty rooms because fans cool people, not the room itself.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
