Fan power consumption and electricity cost
- Last Updated: February 21, 2023
An electric fan is a handy device on those hot and humid days.
And, it is good to know how much electricity an electric fan uses and how much money it will cost us to keep it running.

How much power does an electric fan use
To determine the electricity usage, first you need to know how many watts your electric fan consumes.
This information can be found on the fan’s specifications label or by searching for it on the manufacturer’s website.
Just note that if your electric fan can adjust the airflow intensity level, electricity usage will vary between levels.
If your electric fan is rated with a power of 45 Watts, only the strongest airflow level will consume 45 Watts. In contrast, the lowest or intermediate air flow levels will consume less electricity.
The only way to accurately know an electric fan power consumption over time it is to use a plug in power meter to measure the electricity usage.
Still, if you want to make an estimation, according to its specifications this fan consumes 50 Watts (W).
50 W / 1000 = 0,05 kWh
How to calculate power from voltage and current
If you only know the voltage and current of your electric 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.
Fan electricity cost calculator
The calculator below can be used to estimate an electric fan’s power consumption and electricity cost over time.
You 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 fan has a power rating of 45 Watts (W)
> If you use it 8 hours per day and 120 days per year.
> If you are paying 0,217 euros (or dollars, or pounds, or …) per every kWh you consume
The fan would add around 10 euro (or dollars, or pounds, or …) to your yearly electricity bill.
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 you don’t have access to your contract or electricity bills, this website shows the electricity cost per country.
Home appliances and devices electricity calculators
A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:
Fan electricity usage monitor
Suppose you want to know the exact electricity usage of an air conditioner. In that case, your best option is to use a plug in power meter to measure the exact power consumption and electricity cost.
Clicking on the image below will redirect you to the Amazon page where you can look at the specifications of the power meter we use for our measurements.
All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket.
So, with a power consumption meter we can determine how much electricity our appliances or devices are using, and, more importantly, we can measure the electricity usage over time.
If you want to learn how to use a plug-in power meter to measure your electricity usage and cost, watch this YouTube video.
Fan electricity usage FAQ
Does a fan use a lot of electricity
The electricity usage of a device depends on its power consumption.
A small electric fan does not use much power. Most of them use between 30 to 45 watts.
A low power consumption means that a fan does not use a lot of electricity.
But be careful; more advanced fans or fans with cooling and heating options may use a lot of electricity.
Find out how many watts a fan uses, and you can calculate the electricity usage and cost using the calculator from the ‘Electricity cost calculator’ section.
How many watts does it take to run a fan
Most of the small fans use between 30 to 50 Watts.
Some more advance fans, like the tower fans, will use around 100 Watts.
Fans with additional features, like cooling or heating, will use many more watts. They can use up to 2000 Watts or even more depending on the characteristics.
How much energy does an electric fan use
Energy, power, and electricity are related to the same question: ‘ how much electricity does an electric fan use’ and ‘how much does it cost to run an electric fan.’
Depending on the size and characteristics of the fan, it will use more or less energy/power.
If you want to know how much energy/power a fan use, you need to find the power rating of the electric fan.
Once you know the power rating, you can calculate the electricity usage and cost using the calculator from the ‘Electricity cost calculator’ section.
Are electric fans expensive to run
A small electric fan with power consumption between 30 to 50 Watts is NOT expensive to run.
A larger fan, like a tower fan, with a power consumption of 100 Watts, it is NOT expensive to run unless it is kept on 24×7
A fan with additional heating or cooling features, YES it, can be expensive to run.
Electricity measurement units
Not everybody is familiar with terms like Watts, Kilowatts, or Kilowatt hours, so if you would like to learn more about them, look at this YouTube video we have prepared about this topic.
Electricity measurement units calculators
Or you can have a look to these electricity measurement units calculators to get a better understanding of:
> What is a Watt (W) and how to transform Watts into Kilowatts
> What is a Kilowatt (kW) and how to transform Kilowatts into Kilowatts hour
> What is a Kilowatt hour (kWh) and how to transform Kilowatts hours to other units
> What are Power (P), Voltage (V), and Current (I)
Electric fans 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 help you because you will be paying less on your energy bills.
And it also benefits the environment because conserving electricity prevents unnecessary waste of natural resources.
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 save a little every time, it will make an essential 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 greatly impact preserving our natural resources.
For example, if 9000 households save as little as 10 Watts per day (0,01 kWh) in electric fan’s 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, pounds, or any other currency) per kWh, we would collectively save nearly 6000 euros annually.
> 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.
Look at this page for more information about the number of resources needed to produce electricity.
In any case small energy savings do really count when looking into the bigger picture.
