How payback is calculated here
The assumptions behind your estimate
This calculator begins from planning defaults: a 75 W normal fan set against a 28 W BLDC fan, both run for 250 usage days a year. Payback is then the price difference between the two fans divided by the electricity they save annually at your tariff and your chosen daily hours. Those wattages are convenient starting points, not measurements of the specific fans you are weighing, so read the output as an estimate and adjust the inputs above to match your case. Real rated power differs from model to model — the BLDC vs normal fan guide lists typical figures you can substitute for a closer comparison.
What shortens or lengthens payback
The result is most sensitive to the price gap you enter between the two fans: a modest premium is recovered quickly, while a steep one stretches the timeline out. Your tariff and daily hours decide how much each saved unit is actually worth, so the heaviest users on the costliest electricity reach payback first. The default also leaves out upkeep entirely — if you want to account for capacitor or motor failures over the fan's working life, payback including repair cost folds those expenses into the same model.
Is a BLDC fan the right choice?
There is no single answer for every home. The case is strongest in rooms where a fan runs for many hours a day; for a guest room or a space used only occasionally, savings accumulate slowly and the upfront premium is harder to justify. Efficiency is also not the whole picture — BLDC fans are not flawless, so it is worth reading about common BLDC fan problems before committing.
Common questions
How much electricity does a BLDC fan save per month?
A BLDC fan typically uses 28–35 W compared to 70–80 W for a standard induction fan. Running 8 hours a day, that difference (roughly 40–45 W) saves around 10–12 units (kWh) per month per fan. At ₹6–8 per unit, that is ₹60–100 per fan per month — the exact figure depends on your tariff and usage hours. Use the calculator above for your specific inputs.
How long does a BLDC fan take to pay back?
At typical Indian tariffs (₹5–8/unit) and 8 hours of daily use, a BLDC fan priced ₹2,000–3,500 above a normal fan pays back in roughly 2–4 years. Running the fan more hours per day or paying a higher electricity tariff shortens the payback period.
Is a BLDC fan worth buying in India?
Yes, for most households in India — especially if the fan runs 6+ hours a day. BLDC fans save 50–60% electricity compared to standard fans, have no capacitor to replace, and are compatible with solar inverters. The higher upfront cost is recovered through electricity savings, and the fan continues saving money for its remaining life (typically 8–12 years).
What wattage does a normal ceiling fan use?
A standard 1200 mm induction ceiling fan in India uses 70–80 W at full speed (speed 5). Older or lower-quality fans can draw up to 85–90 W. BEE 5-star rated induction fans have reduced this to around 50–55 W, but BLDC fans go further at 28–35 W for equivalent airflow.
What wattage does a BLDC fan use?
A typical BLDC ceiling fan uses 28–35 W at full speed — about half the power of a standard induction fan. Some premium models claim 25 W or lower. Because BLDC motors run at variable speeds electronically (not via a capacitor), they also maintain efficiency at lower speeds, unlike induction fans that waste power even at speed 1.
