Understanding your fan's running cost
What the calculator assumes
Monthly figures here use a flat 30 days per month and annual figures use 365 days per year, applied to the wattage you pick — whether a preset fan type or a custom value — at the tariff you enter. Treat these as planning estimates rather than a billed amount. Running cost scales linearly with both inputs, so if you double your daily hours or your per-unit rate, the cost simply doubles. That makes it easy to sanity-check a result by adjusting one slider at a time.
Typical wattage by fan type
If you don't know your fan's exact draw, these rough bands for a common 1200mm fan help you choose a starting wattage before you confirm it from the label.
| Fan type | Typical wattage (1200mm) | Relative monthly cost |
|---|---|---|
| Normal induction (1-star) | 70–75 W | baseline |
| Efficient 5-star induction | ~48 W | about two-thirds |
| BLDC | 28–35 W | roughly a third to half |
These are planning estimates — check the BEE star label on your own fan for its rated wattage, since efficiency is rated by CMM and service value, not wattage alone.
Should you switch to a BLDC fan?
The case for switching is strongest where a fan runs long hours, the local tariff is high, or both — that is where the lower wattage translates into a difference you actually notice on the bill. For a spare bedroom or a fan that runs only a few hours a week, the same premium takes far longer to earn back, so an efficient induction fan may be the more sensible buy. If you're weighing the upgrade, the full BLDC vs normal fan comparison covers the motor differences and how the payback maths works out.
Common questions
How much electricity does a ceiling fan use per hour?
A standard 75W ceiling fan uses 0.075 kWh (units) per hour. A 5-star rated fan uses around 0.048 kWh/hr and a BLDC fan uses 0.025–0.035 kWh/hr. Use the calculator above to check the exact cost at your local tariff.
How much does it cost to run a ceiling fan for a month in India?
At ₹7/unit and 8 hours of daily use, a 75W normal fan costs roughly ₹126 per month. A 28W BLDC fan would cost about ₹47 per month under the same conditions — a saving of around ₹79/month.
How many units does a ceiling fan use per month?
A 75W fan running 8 hours a day for 30 days uses 18 kWh (units) per month. A 28W BLDC fan uses about 6.7 kWh/month under the same schedule.
What is the difference in electricity bill between a normal fan and a BLDC fan?
A normal fan (75W) typically costs 2.5–3× more to run than a BLDC fan (28–35W). At ₹7/unit and 8 hours/day the annual difference is roughly ₹960/year per fan. The higher the tariff or daily usage, the faster a BLDC fan pays back its price premium.
How much does a 75W fan cost to run per year?
At ₹7/unit and 8 hours of daily use for 365 days, a 75W fan costs approximately ₹1,533/year. Use the calculator above with your actual hours and local tariff for a personalised figure.
