A table fan in India typically uses 30 to 75 watts, depending on size and motor type. Standard 12-inch table fans with induction motors draw 50 to 55 watts at top speed. 16-inch table fans draw 55 to 75 watts. Newer BLDC table fans use just 28 to 35 watts for similar airflow, around half the power of induction models. Your fan's exact wattage is printed on the label at the back or base.
This guide covers the wattage by fan size, how to read your own fan's label, the cost calculation in INR, and how BLDC technology cuts your running cost in half.

The 12-inch size is the most common in Indian homes for personal cooling on study tables, bedside, or kitchen counters.
The motor type matters more than the size. A 16-inch BLDC table fan can use less power than a 12-inch induction fan while moving more air. For more on how brushless motors deliver this efficiency, see how a BLDC motor works.
A typical Indian table fan label reads something like this:
AC 220V to 240V, 50Hz 55W Made in India
220V to 240V is the voltage range the fan accepts. Indian home power supply is nominally 230V.
50Hz is the frequency of Indian AC power.
55W is the rated power consumption at full speed.
If your fan label shows current (in amperes) instead of wattage, multiply by 230V. For example, "0.24A at 230V" means 0.24 x 230 = 55 watts.

Running a table fan at speed 3 instead of speed 5 cuts your monthly bill by roughly 18%. For overnight use, speed 1 or 2 is enough and uses almost half the power.
The formula: Watts x hours of use ÷ 1000 = kilowatt-hours (units), then Units x electricity tariff = cost.
Take a 50-watt table fan running 8 hours per day at the average Indian residential tariff of ₹7 per unit.

A standard 50W induction table fan on an 800VA inverter with a fully charged 150Ah battery delivers around 12 to 15 hours of fan-only backup. A 30W BLDC table fan on the same inverter delivers 18 to 22 hours, around 50% longer.
This matters for Tier-2 and Tier-3 cities with frequent power cuts during summer.
Traditional induction table fans lose a significant share of input power as heat. The copper windings resist current flow and the iron core generates eddy-current and hysteresis losses. All of that heat is wasted electricity that never reaches the blades.
BLDC (brushless direct current) table fans replace the brushes with electronic commutation. The result: a BLDC table fan delivers the same airflow at 28 to 35 watts that an induction fan needs 50 to 75 watts to produce.
A 30W BLDC table fan running 8 hours a day at ₹7 per unit costs ₹50 per month versus ₹85 for a 50W induction fan. Across a 5-year fan life, that is over ₹2,000 saved per fan.

A table fan in India typically uses 30 to 75 watts. Standard 12-inch fans with induction motors draw 50 to 55 watts. BLDC table fans use just 28 to 35 watts.
A typical table fan in India is 50 to 55 watts at top speed. Smaller 8-inch fans use 30 to 40 watts. Larger 16-inch fans use 55 to 75 watts. BLDC table fans use just 28 to 35 watts.
A 50-watt table fan running at top speed consumes 0.05 units (kWh) per hour. Over 8 hours of daily use, that is 0.4 units per day or 12 units per month. At ₹7 per unit, this is roughly ₹85 per month.
Check the label on the back or base of your fan. The number followed by 'W' is the rated wattage at full speed.
Yes, a table fan typically uses less electricity than an induction ceiling fan. But a BLDC ceiling fan drawing 28 to 35 watts uses the same or less power than most table fans, while cooling a much larger area.
Yes. A 50W table fan on an 800VA inverter delivers around 12 to 15 hours of backup. A 30W BLDC table fan delivers 18 to 22 hours, around 50% longer.
