Worked example
A standard 75W fan running 10 hours/day in Tamil Nadu uses about 0.75 units/day and costs roughly ₹151.88/month (₹1,847.81/year) at ₹6.75/unit.

How this is calculated
Units = wattage × hours ÷ 1000. A fan's daily energy use in kWh is its wattage multiplied by daily running hours, divided by 1000 to convert watts to kilowatts.
Priced at your top slab. Since a fan adds to your existing consumption, its units fall in your highest tariff slab — we use that marginal rate (plus fuel cost adjustment and electricity duty) for a realistic cost.

Frequently asked questions
How much electricity does a ceiling fan use?
A standard Indian ceiling fan draws around 75W. A BEE 5-star rated fan typically uses about 50W, and a BLDC (brushless DC) "super-efficient" fan uses as little as 28–35W for similar airflow — roughly 60% less than a standard fan.
Is a BLDC fan worth the extra cost?
Usually yes if you run fans for many hours a day across a household with several fans — the wattage difference compounds. Use the calculator above with your actual daily hours to see the annual saving versus a standard fan.
Why is the fan priced at my top tariff slab?
Indian electricity tariffs are telescopic — usage is billed in progressively pricier slabs. Any appliance you add sits on top of your existing consumption, so its units land on your highest slab, not a blended average rate.
How can I find my fan's exact wattage?
Check the sticker on the fan's motor housing or the box it came in — Indian fans are required to display rated wattage as part of the BEE star-labelling programme for regulated categories.
