How it works
Annual energy = watts × fan count × daily hours × annual days ÷ 1000. Payback = total extra BLDC price ÷ annual cost savings.
Limits
Actual use changes with speed, voltage, controls and condition. Compare suitable fans with similar air delivery and sweep. Tariff slabs, maintenance and finance cost are excluded.
Use this calculator to compare the estimated electricity use of BLDC and conventional ceiling fans. It also estimates annual cost savings and simple payback for the extra purchase cost.
Enter model-specific values
Use the rated wattage of the exact fans being compared, the number of fans, realistic daily running hours, annual operating days, electricity tariff and purchase-price difference. Compare fans with similar sweep and airflow needs; wattage alone does not describe comfort.
Read savings and payback
Lower wattage can reduce energy use, but the rupee saving depends on operating time and tariff. Simple payback divides the extra upfront cost by estimated annual savings; it does not include repair cost, financing, price changes or product life.
Before buying
Verify wattage, sweep, airflow, speed control, warranty and service availability for each model. If the fan runs only a few hours, payback may be longer. Use your own inputs instead of a fixed savings claim, and treat the output as an estimate rather than a bill guarantee.
