Did you know?
The energy consumption based on an average washing machine is about 400 – 1500 Watts.
Also, the amperage and voltage of your washing machine determine the exact wattage.
The energy consumption of your washing machine may be greater or less. Your washing machine’s exact wattage depends on the brand and the size of your laundry load.
The capacity of your washing machine determines how much energy it uses. The bigger your washing machine, the more watts it needs for each hour of use.
A washing machine uses approximately 90% of the total energy consumed to heat water and completes a wash cycle in 50-60 minutes.
So how can you tell how much energy your washing machine is using?
In this article, we will guide you on how to calculate the exact watts your washing machine is using, as well as the total energy cost per year.
We would offer you recommendations on how to reduce the energy consumed by your washing machine, which would lower your energy cost and enable you to implement energy-saving measures.

The number of watts that your washing machine uses depends on the brand of your washing machine and the wash cycle you use. However, an average washing machine uses about 400 to 1500 watts per hour. The energy your washing machine would use over time might increase depending on how frequently you operate it.
The energy consumption of a washing machine is measured in kilowatts per hour (kWh). To calculate the exact amount of energy that your washing machine uses, you can follow these simple steps:
Find the power rating of your washing machine by consulting the yellow EnergyGuide label on your washing machine. It is also measured in kilowatts per hour (kWh)
Tip: The EnergyGuide Label is different for every washing machine model. You can also find the exact power rating for your washing machine in your owner’s manual or the manufacturer’s website. But here’s what the EnergyGuide should look like:
Estimate how many times you use the washing machine in a year. You should multiply the number of loads you wash in a week by the total number of weeks in a year.
We would be considering a washing machine with power ratings of 340 watts and an average wash cycle time of 50 minutes.
If you do four loads of laundry every week, multiply four loads by 52 weeks: 4 x 52 = 208 laundry loads per year.
Divide the power rating of your washing machine by 60 seconds to determine the watts per minute: 340/60 = 5.67 watts/minute.
Multiply the watts per minute by the duration of your wash cycle: 5.67 x 50 = 283.30 watts. This is the watt per load.
Multiply the watt per load by the number of loads you wash in a year: 283.30 x 208 = 58933.33 watts in a year.
In the United States, most electricity providers charge by kilowatt per hour (kWh). You can get this by dividing the watts per year by 1000.
58933.33/1000 = 58.93 kWh.
To sum it up:
A washing machine with a power rating of 340 watts that runs through four loads per week with a time average of 50 minutes uses 58.93 kWh.
It’s a no-brainer.
Once you have an idea of how many kWh your washing machine uses in a year, you can easily calculate how much its energy cost.
The U.S. Energy Information Administration (EIA) places the average cost of electricity in the United States at 13.45 cents per kilowatt hour.
So how do you calculate it?
Multiply the kWh of your washing machine in a year by the cost of electricity in your area: 58.93 x 13.45 = $7.92 per year.
You should be able to determine your washing machine’s energy costs after following these steps. See the table below to find out how much electricity costs in your area.
|State||Average Electricity Cost ($)||Cost Per Week ($)||Cost Per Month ($)||Cost Per Year ($)|
|New York||21.20 / kWh||0.24||1.04||12.49|
|Florida||14.11 / kWh||0.16||0.69||8.32|
|Maryland||14.31 / kWh||0.16||0.70||8.43|
|Oklahoma||14.45 / kWh||0.16||0.71||8.52|
|Hawaii||45.73 / kWh||0.51||2.25||26.95|
|Utah||11.43 / kWh||0.13||0.56||6.74|
|Kentucky||13.53 / kWh||0.15||0.66||7.97|
|Iowa||15.25 / kWh||0.17||0.75||8.99|
|Virginia||14.35 / kWh||0.16||0.70||8.46|
|US Average||13.45 / kWh||0.15||0.66||7.92|
Note: Average electricity cost rates are based on August 2022 data from the United States Energy Information Administration (EIA).

You don’t have to give up just yet; we are going to discuss some really insightful tips on how to operate your washing machine without accruing too much energy costs.
It is highly recommended to purchase a new model washing machine because they use nearly 50% less energy than their older counterparts.
It is also important to ensure that your washing machine is EnergyStar certified before you make a purchase.
Many customers commented on how they noticed a reasonable reduction in their electricity bills after doing this.
One very important thing you should know is that your washing machine uses about 90% of its total energy to heat water, which can significantly increase your electricity bills over time.
Using hot water to wash your clothes frequently could cause them to shrink or fade. You could save a considerable amount of money and energy if you use cold water for your routine laundry.
You should always remember to unplug your washing machine from its power source immediately after use.
You might assume your washer automatically turns off when it’s not in use.
These washers are usually on standby mode, and you must turn them off manually.
Clothes with tough stains may be difficult to wash, and you may need to run more than one wash cycle to make sure that your clothes are clean.
Soaking these clothes in water and stain removal would help soften these stains, allowing your clothes to get clean in one wash cycle.
Doing this would help reduce the number of wash cycles, which will lower your energy costs.
Your washer would use the same amount of energy regardless of the size of your laundry load. It is best if you wash full laundry loads to minimize the times you’d have to run your washing machine.
Allocate two to three days a week for laundry, and make sure to do all your laundry at once.
You might have a small size of laundry to do urgently. You can use the quick wash feature on your washing machine that allows you to finish a wash cycle in 15 to 20 minutes.
Most washing machines have these features that allow them to operate efficiently while using the least amount of energy possible.
Make sure you use these modes as much as possible if your washer model has them. These modes save power which will help lower your yearly electricity cost.
If you are concerned with how much power your washer consumes and looking for ways to cut down electricity costs, what you have to do is simple.
Calculate the number of watts your washing machine uses in a year by simply multiplying the power rating of your washer by the duration of use.
Energy consumption (wattage) = Power rating x Duration of use (usually in hours)
You can get the power rating of your washing machine by consulting the yellow EnergyGuide label on your washing machine.
Some of the things you can do to lower your energy cost are:
- Use cold water for routine laundry.
- Use newer models of washing machines, which are usually 50% more efficient than old ones.
- Purchase EnergyStar Certified washing machines.
- Activate the Eco mode on your washing machine. This helps to reduce the power consumption of your washing machine.
