Calculate power consumption for standard 75W ceiling fans vs 28W BLDC 5-star energy saving fans.
Understanding how much power your ceiling fan consumes is essential for controlling monthly household utility bills. In India, power rates vary between ₹3.00 and ₹11.00 per kWh unit depending on your state tariff slab tier.
Operating a ceiling fan with high energy efficiency ratings (5-Star or Inverter technology) significantly lowers your overall unit consumption, keeping your meter within lower pricing slabs.
Example: 75 Watts × 12 Hours × 30 Days ÷ 1000 = 27 kWh units per month.
Check the specification sticker on your ceiling fan for rated wattage (e.g. 75W).
Multiply wattage by operating hours per day and 30 days to get monthly Watt-hours, then divide by 1,000 for kWh units.
Multiply net monthly kWh units by your state electricity tariff slab rate (e.g. ₹7.00/unit) to find total monthly cost.
| Ceiling Fan Specification / Variant | Wattage (W) | Daily Usage (Hrs) | Monthly Units (kWh) | Est. Monthly Bill (₹) |
|---|---|---|---|---|
| Standard Ceiling Fan (75W) | 75 W | 12 hrs/day | 27 kWh | ₹189 |
| BLDC 5-Star Energy Saver Fan (28W) | 28 W | 12 hrs/day | 10 kWh | ₹70 |
| Appliance Energy Technology | Annual Units (kWh) | Est. Annual Electricity Bill (₹) | Energy Rating |
|---|---|---|---|
| Standard 75W Induction Fan | 328 kWh/yr | ₹2,296 | High Power |
| BLDC 28W 5-Star Smart Fan | 122 kWh/yr | ₹854 | Best (Saves ₹1,442/yr/fan) |
No! Two ceiling fans consume only 150 Watts total (or 56 Watts for BLDC fans), whereas a 1.5 Ton AC consumes 1,200 to 1,600 Watts. One AC uses as much electricity as 8 to 10 ceiling fans combined.
A 28W BLDC fan consumes 60% less power than a standard 75W fan, saving approximately ₹1,400 to ₹1,800 per fan per year on continuous usage.

Simple household adjustments can reduce your monthly power consumption and keep you in lower tariff slabs.
Each degree higher saves ~6% electricity. Running at 24°C instead of 18°C can lower your monthly cooling bill by ~24%.
Brushless DC (BLDC) motor fans consume only 28W compared to 75W for traditional ceiling fans, cutting fan power usage by over 60%.
Appliances in standby mode (TVs, set-top boxes, chargers) consume 5–10% idle electricity. Turn them off at the main switch.
Residential rooftop solar installations receive up to ₹78,000 in central subsidies, generating free green power with net-metering.
Clean refrigerator condenser coils annually and set geysers to 50°C with an auto-timer to prevent overheating and energy waste.
Energy-efficient 9W LED bulbs output the same light as 60W incandescent lamps while consuming 85% less electricity.
Consumed units (kWh) are split into progressive tariff tiers with respective unit rates.
Monthly fixed charges are calculated per kW (or kVA) of sanctioned load.
Fuel Adjustment Charges (FAC/FPPPA) and state electricity duty percentages are added.
State government zero-bill / free unit schemes (e.g. Gruha Jyothi, DERC) are deducted for the final estimate.
