Formula:
Monthly energy (kWh) = Fan power (W) × Number of fans × Hours/day × Working days/month ÷ 1,000.
Monthly operating cost = Monthly energy × Electricity rate.
How It Works
How to Calculate Fan Electricity Consumption
The calculation uses rated fan power and expected operating time to estimate energy use. This is useful for both individual household fans and larger commercial or industrial fan installations.
Add Quantity & Usage
Enter how many fans will operate, the average daily hours, and the expected working days each month.
Enter Local Electricity Rate
Use the electricity price per kWh in your country, city, building, or commercial tariff.
Compare Operating Cost
Review estimated daily and monthly energy use plus monthly and annual electricity cost.
Source the Right Fan
Calculate First. Then Compare Fan Options.
Power consumption is only one purchasing factor. Airflow, motor configuration, fan size, installation, voltage, noise expectations, packaging, and target market requirements should also be considered.

FAQ
Fan Electricity Cost Questions
These answers explain how the calculator should be used when comparing household, commercial, and industrial electric fan options.
How do I calculate fan electricity consumption?
Convert fan wattage to kilowatts by dividing watts by 1,000, then multiply by the number of fans,
operating hours, and working days. The result is estimated electricity consumption in kWh.
Can I use this calculator for both household and industrial fans?
Yes. The formula is the same. Enter the rated wattage and expected usage for the specific household,
commercial, or industrial fan you are evaluating.
Do higher-wattage fans always provide better airflow?
Not necessarily. Wattage is electrical input, while useful airflow also depends on motor design,
blade geometry, fan size, speed, grille design, and overall product configuration.
Why can actual electricity consumption differ from the estimate?
Actual consumption can vary with fan speed, voltage, motor efficiency, load, operating conditions,
and the difference between rated input power and measured running power.
Can SF Fan provide power data before a bulk order?
Yes. For a specific project, buyers can send the target fan type, size, voltage, quantity, market,
and performance requirements so the relevant product specifications can be reviewed before ordering.
