# Hair Dryer Power Consumption Calculator

Share the article

Hair dryers are a common household appliance used nowadays in most part of the world. Using this simple calculator you can calculate power consumption of your hair dryer.

The rated power of a hair dryer varies from 1000 watt to 3000 watt, with 1500 watt being the average wattage of a standard size hair dryer. The power consumed by a 1500 watt hair dryer for 10 minutes of operation is around 0.25 kWh. Hence in a month it’s power consumption will be 7.5 kWh.

## Hair Dryer Rated Power:

The rated power of hair dryer varies from 1000 watt to 3000 watt. Most standard size hair dryer used in household has around 1500 watt whereas hair dryers used in salon has around 2500 watt to 3000 watt.

All hair dryers have three modes to adjust the temperature of air coming out of it. If you use the high temperature mode naturally power consumed will be more and if you go with the normal temperature mode the power consumed will be less.

Almost 80 % of the heat used by hair dryer is used to heat the air for effectively drying your hair.

If you don’t know the wattage of your hair dryer then check the product specification sticker on it or just find your hair dryer or a similar type dryer on amazon and check it’s wattage.

I have pulled up specification of three hair dryers to give you a rough idea on the different wattage range hair dryer available in the market.

## Hair Dryer Power Consumption Calculator:

To calculate your hair dryer (blow dryer) power consumption and interpret the results correctly you need to know and understand the following four parameters:

1. Wattage: Wattage is the rate at which any appliance consumes power. For example a 1500 watt hair dyer consumes 1500 watt of power every hour.
2. Operational Hours: Operational hours is the number of hours an appliance is in operation. For example a hair dryer running for 30 minutes mean it’s operating hours is 0.5 hours.
3. Electricity Tariff: Electricity tariff is the amount your electricity provider charges you for one unit of electricity. I live in Mumbai, India here electricity tariff is Rs 12 / kWh. Whatever is the electricity tariff in your area type it in the electricity tariff tab.
4. Unit Of Electricity (kWh): The power consumed by any device is measured in units of electricity or (kWh). For example a 500 watt AC running for 8 hours will consumes 500 watt X 8 hours = 4000 watt hours or 4 kWh of electricity.

Now that you know all the above parameter it’s time to use the calculator below.

To give you a rough idea on power consumption, if you use your hair dryer daily for 10 minutes then in the entire month it’s power consumption will be (1.5 kW X 0.166 hour X 30 days) 7.5 kWh. A 1 ton AC running for 8 hours daily will consume 7.5 kWh in just 2 days.

The calculated results are approximate values and you can expect 10 % error on either side.

However if you are not satisfied with an approximate value and want to know exact power consumption of your hair dryer then can use a Kill A Watt meter to find it.

### Calculate Power Consumption Of A Hair Dryer Using a Kill A Watt Meter:

Kill a watt meter is a simple device used to calculate power consumption of any device.

You can buy it from amazon using this link. Kill A Watt Electricity Usage Monitor

To use the Kill A Watt meter first connect your hair dryer plug to the Kill A Watt meter and then plug the Kill A Watt meter in your wall socket.

Then start using your hair dryer the way you do normally and you can see in real time how many kWh (units) of electricity your toaster is using.

Check out this tutorial video from altE to understand how to use a kill A Watt Meter to track your appliance energy consumption.

### Conclusion:

After calculating the results you would agree that even though the wattage of a hair dryer is high, their monthly power consumption is less because their daily operational hours is less (20 minutes / day at max). Hence don’t worry about the the power consumption of your hair dryer.
