Ceiling fans are one of the cheapest ways to stay cool – a fan uses a fraction of the electricity an AC does, because it just moves air rather than actively cooling it. Our free Ceiling Fan Electricity Cost Calculator below shows you the daily, monthly and yearly running cost based on your fan’s wattage, how many hours you run it, and how many fans you have running.

Check the label on the fan motor housing. Standard ceiling fans use 60-90W, BLDC/energy-saving fans use 25-35W, large industrial fans can use 100-200W.

How Much Electricity Does a Ceiling Fan Use?
A ceiling fan's running cost depends on its wattage, how many hours you run it, and your electricity rate. Unlike an AC compressor, a fan motor runs at a fairly constant draw whenever it's switched on - there's no duty cycle to account for. The formula is:
Cost = (Wattage x Number of Fans / 1000) x Hours Used x Electricity Rate per kWh
Ceiling fans are dramatically cheaper to run than air conditioners - a standard 75W fan uses roughly 1/20th the electricity of a 1.5-ton AC. That's why running fans alongside a higher AC thermostat setting (or instead of AC on milder days) is one of the simplest ways to cut a cooling bill.
Ceiling Fan Cost by Type
| Fan Type | Typical Wattage | Cost/Month (India, Rs 8/kWh, 8hr/day) | Cost/Month (US, $0.17/kWh, 8hr/day) |
|---|---|---|---|
| Standard Induction Fan | 70-90W | Rs 134-173 | $2.86-3.67 |
| BLDC / Energy-Saving Fan | 28-35W | Rs 54-67 | $1.14-1.43 |
| Table / Pedestal Fan | 50-75W | Rs 96-144 | $2.04-3.06 |
| Large Industrial Fan | 120-200W | Rs 230-384 | $4.90-8.16 |
4 Ways to Cut Your Fan Electricity Bill
- Switch to a BLDC (brushless DC) fan - these use 60-70% less power than a standard induction motor fan for the same airflow, typically 28-35W vs 75W.
- Use the regulator's lower speeds when possible - a fan on speed 3 instead of speed 5 draws noticeably less power while still keeping the room comfortable.
- Turn fans off when you leave the room - fans cool people, not rooms, so there's no benefit to running one in an empty room.
- Pair a fan with a slightly higher AC thermostat setting - the wind-chill effect of a fan lets you feel comfortable at 2-3 degrees C higher, cutting AC duty cycle and cost significantly for a tiny fan cost.
Frequently Asked Questions
How many watts does a ceiling fan use?
Standard induction-motor ceiling fans use 70-90W. Modern BLDC (energy-saving) ceiling fans use only 28-35W for similar airflow, cutting running cost by 60-70%.
How much does it cost to run a ceiling fan all day?
A standard 75W fan run for 24 hours costs about Rs 14.40 per day in India (at Rs 8/kWh) or roughly $0.31 per day in the US (at $0.17/kWh).
Is a ceiling fan cheaper than an air conditioner?
Yes, dramatically so. A ceiling fan typically uses 1/15th to 1/20th the electricity of an air conditioner for the same number of hours, since it only moves air rather than actively cooling it.
Do BLDC fans really save money?
Yes. BLDC ceiling fans draw around 28-35W compared to 70-90W for a standard motor - roughly 60-70% less power for similar airflow, which pays back the higher upfront cost within 1-2 years of regular use.
Does fan speed affect electricity cost?
Yes, slightly. Running a fan on a lower regulator speed reduces power draw somewhat, though the difference is much smaller than the difference between fan types.
Should I run multiple fans instead of one AC?
On mild days, yes - a few fans running all day still cost far less than a few hours of AC. On very hot or humid days, fans alone may not keep you comfortable and an AC (used efficiently) may be necessary.
