- How much electricity does a hair dryer use? -

To get to know how much electricity does a hair dryer uses, first we need to know how much power does it use.

Depending on the model, a hair dryer can use from around 1500 Watts up to 3000 Watts.

So, first, you need to know how many watts (W) does your hair dryer uses. This information can be can be found on the hair dryer’s specifications label.

Alternatively, if you are considering to buy a new hair dryer, that wattage can be found on the internet by browser search. Just browse for the hair dryer’s model followed by ‘wattage’ or ‘ power consumption’.

Hair dryer wattage search

Our hair dryer uses 2100 Watts (W) or 2,1 Kilowatts per hour (kWh). Because we are paying to our electricity provider 0,217 euro per every Kilowatt hour we use, we know that if we were to use the hair dryer continuously for an hour it would cost us 0,45 euro.

Electricity usage and cost calculator

Once you know the power consumption, the calculator below can be used to estimate the power consumption and the electricity cost of a hair dryer 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 you have a hair dryer which is rated as 3000 Watts (W)
  • If you use the hair dryer 15 minutes every day and 210 days per year
  • If you are paying 0,2 euro (or dollars, or pounds, or…) per every kWh you consume 

You will be paying around 31,5 euro (or dollars, or pounds, or…) per year in electricity costs.

Still, if you want to know the exact electricity usage of your hair dryer, you need to use a plug-in power meter.

For more details, have a look to this post that we have created to show you how to use a plug in power meter to measure your appliances and devices power consumption.

Plug in power meter electricity consumption

We have measured a 2100 Watts hair dryer’s power consumption and the results are as follow.

As you can see, the hair dryer’s electricity consumption depends on the settings. 

This means that the power consumption stated on the device label can be used for orientation, to calculate the approximate electricity usage and cost, but to get to know the exact values a power meter it is advisable.

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

If you are looking for saving electricity at home, have a look to this video where we provide some useful tips to reduce the electricity consumption and decrease the electricity bill.

Electricity conservation - Save and conserve energy

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 on your energy bills. 

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

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

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


For example, if 9000 households would manage to save as little as 10 Watts per hour (0,01 kWh) worth of electricity per day, that would add to 32850 Kilowatt hour (kWh) per year. 

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

  • Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) we would collectively be saving nearly 6000 euro per year.
  •  To produce 32850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
Have a look to this page for more information about the amount 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.

We hope that you have found the information on this page informative and of value.
