Find out exactly how much your ceiling fan costs to run — per hour, per day, per month and per year. Supports India ₹/unit rates and global $/kWh, speed settings, multiple fans, DC vs AC motors and a side-by-side comparison with air conditioning running costs.
The formula is: kWh = (Watts × Hours) ÷ 1000. Then: Cost = kWh × Electricity Rate. For a 65W fan running 8 hours at ₹7/unit: (65 × 8) ÷ 1000 × 7 = ₹3.64 per day. Our calculator adds speed factor (40–100%) and motor type adjustments for BLDC fans, giving you a far more accurate result than basic tools.
Most ceiling fan calculators ignore speed settings — but they make a huge difference. A fan on low speed uses roughly 40% of rated wattage. On medium: ~70%. On high: 100%. A 75W fan on low actually draws about 30W — the same as a basic LED bulb. Running on low instead of high can cut your fan's electricity cost by 60% across a summer.
A 1.5T AC in India uses 1,400–2,000W per hour versus a ceiling fan's 25–90W. Running a fan costs ₹70–150 per month. An AC on the same schedule costs ₹2,500–4,500 per month. The smart approach: use both together. Set your AC to 24°C and run a fan — this lets you raise the thermostat by 4°C, cutting AC costs by 20–30%.
