Ceiling fan power consumption and electricity cost

A ceiling fan can be used to both cool and heat our houses.

But, they do use electricity so it is good to know how much electricity a ceiling fan use and how much it costs to run a ceiling fan.

How much power does a ceiling fan use

To get to know how much electricity a ceiling fan uses, first you need to know how much power it consumes.

The power consumption of a ceiling fan can be found on its energy label.

Alternatively, the power consumption can also be found by searching for the fan specifications on the internet.

ceiling fan power consumption

For example, if your ceiling fan is rated as 50 Watts (W), this means that it will consume 0,05 Kilowatts per hour (kWh).

50 W / 1000 = 0,05 kWh

Just note that the power consumption is only a rough estimation because it will vary depending on the settings. 

For example, a lower fan speed will most probably use less power than a medium or higher fan speed.

How to calculate power from voltage and current

If you only know the voltage and current of your ceiling fan, you can calculate the power consumption, in Watts, using the calculator below.


For more information about Power, Voltage and Current, scroll down to the ‘Electricity Measurement Units’ section.

Ceiling fan electricity cost calculator

Once you know the power consumption, the calculator below can be used to estimate the electricity cost of a ceiling fan over a period of time.

You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.


For example:

> If your ceiling fan has a power rating of 50 Watts

> If you use it for 10 hours a day and 220 days per year

> If you are paying 0,2 euros (or dollars, or pounds) per every kWh you consume 

You will be paying 15,4 euros (or dollars, or pounds, or…) per year in electricity costs.

How much does electricity cost

If you don’t know how much you are paying per kWh, you should be able to find the cost per kWh on your electricity contract or in one of the electricity bills.

Alternatively, if don’t have access to your contract or your electricity bills, this website does show the electricity cost per country.

How to use a ceiling fan to lower the electricity bill

If used correctly and efficiently, a ceiling fan can save electricity on heating and cooling

Here there are some tips and facts that can be of your interest:

1.- Use the ceiling fan to create a cooling breeze during summer

Most ceiling fans have an option that allows the users to choose the rotation type, clockwise or counterclockwise.

During summer, make sure that the rotation of your ceiling fan is pushing the air down, from the ceiling to the floor. That will create a nice and refreshing draft.

An air conditioner uses much more electricity than a ceiling fan so supplementing an air conditioner with a ceiling fan will decrease your electricity usage by efficiently distributing the cool air produced by the air conditioner unit.

2.- Use the ceiling fan to efficiently distribute the heat during winter

During winter, make sure that your ceiling fan is set up to pull the air from the floor to the ceiling.

This airflow will pull the hot air from the floor to the ceiling, across the ceiling, and back down by the sides to the floor of the room.

An efficient heat distribution will reduce the amount of electricity used for heating and therefore reduce your electricity cost.

3.- Use your ceiling fan only when needed

A ceiling fan can be a good supplement to save on heating and cooling when used efficiently. Just make sure that you power off your ceiling fan when it is not needed.

How many watts does a ceiling fan use?

A ceiling fan does use around 50 Watts.

How much energy does a ceiling fan use?

In the contest of ceiling fans, energy and power are the same.

A ceiling fan does use around 50 Watts.

How much electricity does a ceiling fan use compared to air conditioning?

As you can see on the ‘Ceiling fan electricity usage and cost calculator’, it takes just a few watts to run a ceiling fan and they are quite economic.

And the air conditioning unit is a totally different story…

For more information, have a look at the page where we explain the electricity usage and electricity cost of an air conditioning unit.

On that page we have made available a calculator that can be used to calculate the electricity cost of an air conditioning unit over a period of an hour, day, and year.

Do fans or air conditioners use more electricity?

In 99% of the cases, an air conditioner uses more electricity than a ceiling fan.

There is only one situation when a ceiling fan will use more electricity than an air conditioner.

If the air conditioner it is barely used but the electric fan is in use 24×7, over time the electric fan will use more electricity than an air conditioner.

If you want to have more details, compare the ‘Electricity cost calculator’ results between a ceiling fan and an air conditioner.

How much electricity does a ceiling fan use per month?

In the ‘Electricity cost calculator’ section we have made available a calculator that can be used to calculate the electricity usage and electricity cost of a fan.

‘How much electricity does a ceiling fan use per month’ will depend on two factors: The power consumption of the ceiling fan and how many hours per day is the ceiling fan in use.

Electricity measurement units

Not everybody is familiar with terms like Watts, Kilowatts, or Kilowatt hours so if you would learn more about them, have a look at this YouTube video that we have prepared about this topic.

Ceiling fan and energy conservation

Energy conservation can be defined as the decision and the act of using less energy

Energy conservation both benefit you and the environment

The act of saving and conserving electricity does benefit you because you will be paying less for your energy bills. 

And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.

Now, at the individual level, it may not look worth trying to save a few watts here or there. 

Still, every little count and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.

Energy conservation calculator

If we could reduce the electricity usage of our electric fans, even a very small amount, it would make a big impact on preserving our natural resources.


For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) on electric fans’ electricity usage, that would add to 32850 Kilowatt hours (kWh) saved per year. 

9000 households x 0,01 kWh per day x 365 days per year 

32,850 kWh saved per year

That is a considerable amount of electricity, but let’s add additional perspectives for clarity:

> Assuming an average cost of 0,18 euros (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euros per year.

> To produce 32,850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.

Have a look at this page for more information about the number of resources needed to produce electricity.

In any case, it is clear that small energy savings do really count when looking into the bigger picture.
