Washing machine power consumption and electricity cost

The electricity usage of a washing machine may vary considerable depending on the efficiency and age of the appliance.

Newer and efficient models most probably are going to be more economic. Still, if you have a washing machine at home or if you are considering to buy one, it is worth to spend a little time and find out the electricity usage and the electricity cost.

How much power and electricity does a washing machine use

Depending on the model, a washing machine uses between 400 to 2500 Watts of power per hour.

The electricity usage, or the power consumption, should be clearly displayed or easily at the appliance itself of easily accessible online.

Electricity usage of a washing machine

Still this is not always the case. If the electricity usage is low, the power consumption details are easy to find. 

And the opposite, is the electricity usage is higher that other similar washing machines, the power consumption details may be a bit hidden.

For example, according to the energy label of this washing machine, it is estimated that it will consume 130 Kilowatt hours (kWh) of electricity per year. 

Because we are paying to our electricity provider 0,217 euro per every kWh we consume, in our case to use this washing machine would add around 28,2 euro per year to our electricity bill.

130 kWh x 0,217 euro per kWh = 28,21 euro per year

How to calculate power from voltage and current

If you only know the voltage and current of your washing machine, 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.

Washing machine electricity cost calculator

We have chosen a random washing machine and made a simple search for its ‘datasheet’. Out of the results, we have been able to find its power consumption both at Amazon and at the manufacturer’s website.

Washing Machine Datasheet

Once we know the yearly power consumption, the calculator below can be used to estimate the power and cost consumption of the washing machine.

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 washing machine has a power consumption of 130 kWh per year

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

You will be paying around 26 euro (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.

Still, if you want to know the exact electricity usage of your washing machine, your best option is to use a plug in power meter to measure the electricity consumption. 

Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.

plug in power meter

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 a period of time.

How to lower the electricity bill of a washing machine

If you are giving a lot of use to your washing machine, the electricity usage can be fairly high. Here there a few tips to reduce the electricity usage of a washing machine:

1.- Wash the clothes in cold water

If possible, wash the clothes in cold water as the washing machine will not use electricity to heat up the water and that will save electricity.

2.- Use the Eco mode

Most of the new models do have a Eco mode that it is optimized to get the best result with the least amount of electricity. The Eco mode may not be the quickest program but it will be the most economic.

3.- Run full loads

Find out what is the maximum amount of clothes that your washing machine can wash efficiently and make sure that you only run full loads.

Just note that trying to cram the washing machine with too many clothes can be as detrimental as running partial loads.

4.- Buy an efficient washing machine

If you are considering to buy a new washing machine, look for an efficient model. An efficient model will save you both electricity and water. 

Washing machine electricity usage FAQ

How many watts does a washing machine use

Depending on the model, a washing machine uses between 400 to 2500 Watts per hour.

The power usage will depend on the washing setting or program being used.

For example, on a washing machine the ECO program is going to use much less power (watts) than the Auto program.

How many watts does a washing machine use per hour

Same answer as above.

Depending on the model, a washing machine uses between 400 to 2500 Watts per hour.

The power usage will depend on the washing setting or program being used.

For example, on a washing machine the ECO program is going to use much less power (watts) than the Auto program.

How much energy does a washing machine use

Power, energy, watts,… do not mean exactly the same but when it comes to appliances and devices, energy and power can be considered as equal.

As responded to the questions above.

Depending on the model, a washing machine uses between 400 to 2500 Watts (power, energy) per hour.

The power usage will depend on the washing setting or program being used.

For example, on a washing machine the ECO program is going to use much less power (watts) than the Auto program.

How much electricity does a washing machine use per hour

It depends on the efficiency of the washing machine, and the settings or program used for washing.

For example, on a washing machine the ECO program is going to use much less power (watts) than the Auto program.

How much electricity does a washing machine use per load

It depends on the efficiency of the washing machine and the setting or program used for washing.

Nowadays, the washing machines manufacturer’s website do provide quite a lot of information about the electricity usage.

There is quite a chance that if you search for a specific washing machine model on the manufacturer’s website, they will at least show the electricity usage for the most common washing programs.

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 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.

Energy conservation calculator

If we could reduce our washing machines electricity usage, 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 the washing machines electricity usage, that would add to 32850 Kilowatt hour (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 euro (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euro 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 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.
