Ceiling Fan Power Consumption Calculator

Calculate Power Consumption of Ceiling Fan:

how much power does a fan use in a month

Using the ceiling fan power consumption calculator you can calculate the amount of electricity your fan uses in a month and what impact it has on your monthly electricity bill.

The power consumption of any fan depends on the sweep (radius) of the blades, the air delivery rate and the revolution per minute of the motor, but to give you a ballpark figure most ceiling fans consume power anywhere between 60 -100 watts. (without BEE energy saving star ratings)

If you want to find the exact rated power of your ceiling fan, then google you fans brand name or find the your fan in amazon and you should be able to find the wattage of your fan in the product description.

If you don’t want to do the google search then just take 75 watts as most household fans consumes power somewhere around 75 watts +/- 10 watts.

To use the ceiling fan power consumption calculator to calculate the power consumption of your ceiling fan, table fan, exhaust fan or any fan and interpret the results correctly you should understand the following terms.

If you know these terms then feel free to scroll down to use the fan power consumption calculator.

  • What is Watt (W) – Watt is a unit of power. It means the rate at which electricity is consumed or produced by a device. For example a 50 watt TV consumes power at a rate of 50 watts per hour, it does not mean that the TV consumed 50 units of electricity, it means it will consume power at a rate of 50 watts every hour.
  • What is Kilowatt (kW) – Kilowatt is also a unit of power. Kilowatt (KW) is used for large devices that consume more power. For example a 1.5 kW air conditioner, 6 kW elevator. There are bigger units like Megawatt (MW), Gigawatt (GW) to describe large power consumption or generation. For example 100 Megawatt (MW) coal power plant.(1 kW = 1000 W)
  • What is a Kilowatt hour (kWh) – Units as described in electricity bill a.k.a kilowatt hour is the energy consumption of a device. For example a 50 watt Television (TV) running for 50 hours will consume 50 watt x 50 hours = 2500 watt hours = 2.5 kilowatt hours of electricity = 2.5 units of electricity.(1 kWh of electricity = 1 unit of electricity)
  • Electricity Tariff – Electricity tariff is the amount the electricity provider charges you for one unit (kWh) of electricity. I live in Mumbai, India here the electricity tariff is Rs 12/kWh. If you don’t know how to calculate your tariff then just divide your total bill by monthly power consumption and you will get your electricity tariff.
  • What is operational hours – Operational hours of a device refers to how many hours the device is working. If you run your television for 3 hours then operational hours of your television is 3 hours.

To calculate the power consumption of your ceiling fan, table fan, exhaust fan, just put the wattage of your fan, operational hours and electricity tariff in your locality and you will get the units of electricity your fan will consume and the impact it will have on your electricity bill.

If you don’t know the wattage then type in 75 watts.

How To reduce power consumed by a fan:

Well you will agree with me that fans don’t consume much power after all, but there are ways using which you can reduce the power consumption of your fan by some margin, let’s look into it.

  1. Replace your fans with BEE five star rated fans, they consume 10-15% less power for the same wattage and rpm than a conventional fan without BEE ratings,
  2. If you are planning to change your fans then opt for Brush less DC motor (BLDC) fans. They consume as low as 30 watts for same air delivery and speed.
  3. The obvious one is to turn off the fans when not in use. This is something we all ignore but can save you good amount on your electricity bill.
