Although you may only use your dryer once every few days (or even less), it can still use an impactful amount of electricity. While not quite as power-hungry as appliances like air conditioners, dryers use more electricity than washing machines, and it's important to know how much electricity your dryer uses when you're looking at your whole home's energy usage.

Key Takeaways

  • On average, dryers use 1,500 to 5,000 watts of electricity – this number is highly dependent on the model you have

  • Using a clothes dryer three times a week will use about 468 kilowatt-hours of electricity per year.

  • It costs an average of $5.53 to run a dryer for a month and $66.41 to run for a year.

  • The best way to save on electricity is to install solar panels. Start comparing your options on the EnergySage Marketplace today.

On average, a clothes dryer uses 1,500 to 5,000 watts (W) of electricity, depending on the model. Most clothes dryers use between 7.5 and 30 amps and connect to a 240-volt outlet.

How much you run your clothes dryer has the biggest impact on how much electricity it uses over time, and households have all sorts of laundry routines. To cover a range of schedules, we'll outline three scenarios: using your clothes dryer once a week, three times a week, and every day of the week. Assuming a dry cycle takes one hour:

  • If you run a 3,000 W clothes dryer once a week, that's 3 kilowatt-hours (kWh) of electricity per week, 13 kWh per month, and 156 kWh per year.

  • Running that same dryer three times a week comes to 9 kWh per week, 39 kWh per month, and 468 kWh per year.

  • If you run a 900 W clothes dryer every day, that's 21 kWh of electricity per week, 91 kWh per month, and 1,092 kWh per year.

Different-wattage clothes dryers use different amounts of electricity over the course of a year. Assuming you run your clothes dryer an average amount (3 days per week, or 156 days per year), here's how much electricity you'll use over the course of a year:

How many watts do different clothes dryers use in a year?

Clothes Dryer Wattage
Days Per Week Run
Yearly K Wh Of Electricity
1,500 W3234 kWh
2,000 W3312 kWh
2,500 W3390 kWh
3,000 W3468 kWh
3,500 W3546 kWh
4,000 W3624 kWh
4,500 W3702 kWh
5,500 W3780 kWh

We'll mostly be referring to the electricity used by clothes dryers in terms of kWh in this article. The reason is simple: your electric bill is measured in kWh, and you get charged based on the kWh of electricity you use per month!

How many volts and amps does a clothes dryer use?

The wattage of an appliance is determined from its voltage and amperage. You can use the yellow EnergyGuide label on your clothes dryer to determine the volts and amps it uses.

Using the above example label (for a washing machine, which uses less electricity than a clothes dryer), here's how you can calculate volts and amps:

  1. Translate energy consumption to watt-hours (Wh) by multiplying the label's kWh by 1,000. This gives you 135,000 Wh.

  2. Divide 135,000 Wh by the number of days in a year you would use your clothes dryer – we'll say 150 – which gives you 900 Wh per day. clothes dryers usually cycle for an hour, so that's 900 W of hourly wattage.

  3. clothes dryers usually use 120-volt outlets. Divide the 900 W by 120 volts to get the amperage for your appliance: 900 W / 120 V = 7.5 amps.

When you get your monthly electric bill, you only get to see the total amount you're charged, not how much each appliance contributes to your final bill. Based on an average wattage of 3,000 W for clothes dryers (amounting to 468 kWh/year if you run it three days a week) and using state average electricity rates, here's how the cost to run a clothes dryer pans out over the course of a month and a year:

Monthly and yearly costs to run a clothes dryer by state

Average Electricity Rate

Cost Per Year
California22.00 ¢ / kWh$8.58$102.96
New York20.59 ¢ / kWh$8.03$96.36
Texas12.56 ¢ / kWh$4.90$58.78
Massachusetts22.59 ¢ / kWh$8.81$105.72
Florida12.21 ¢ / kWh$4.76$57.14
Virginia12.58 ¢ / kWh$4.91$58.87
New Jersey16.20 ¢ / kWh$6.32$75.82
Maryland14.48 ¢ / kWh$5.65$67.77
Washington10.38 ¢ / kWh$4.05$48.58
US Average14.19 ¢ / kWh$5.53$66.41

Note: average electricity rates are based on October 2021 data from the U.S. Energy Information Administration (EIA).

Looking to offset your electric bills (and the energy these appliances use) with solar? When you sign up (for free!) on the EnergySage Marketplace, you can compare solar quotes from high-quality, local solar installers. Make sure to keep in mind your current and future electricity usage, and talk about how that could change with your installer for the most accurate quotes.

Calculate how much energy your own clothes dryer uses

Remember that yellow Energy Saver sticker we mentioned above? If you want to know how much electricity your clothes dryer uses (or at least is supposed to use), take the estimated yearly electricity use in kWh – this is probably your best bet for an accurate number. Simply multiply this number by the average electricity rate in your area to get an estimate of how much you spend to power your clothes dryer each year. For an estimated monthly cost, divide the estimated yearly cost by 12.

What's the best time to run a clothes dryer?

If you're on a time-of-use (TOU) rate plan, you are charged different amounts for electricity throughout the day. In general, it's cheaper to use appliances during "off-peak" hours, which are usually overnight.

What size battery do you need to back up a clothes dryer?

Just about all popular home batteries are capable of powering a clothes dryer: most lithium-ion batteries like the Tesla Powerwall or Generac PWRcell have a power rating of 4 to 5 kW or higher and 10+ kWh of usable capacity. Clothes dryers use 1,500 to 5,000 W (1.5 to 5.0 kW) of power at any one time, meaning several batteries will be suitable on their own for backing up and powering your clothes dryer.

How many solar panels does it take to run a clothes dryer?

Average clothes dryers use between 1,500 and 5,000 W of electricity to stay powered. On average, solar panels are rated at around 350 W, meaning you'll need about 8-9 panels to power clothes dryers rated at 3,000 W.

What are ENERGY STAR appliances?

ENERGY STAR is a U.S. government-backed system that certifies how energy-efficient appliances are. If an appliance is better than the average appliance in its category by a certain amount, it is labeled as "ENERGY STAR certified." ENERGY STAR appliances cost less money to run, given that they are more efficient with the electricity they use.

Solar savings vary widely, and your unique savings depends on factors like electricity usage, your location, electric rates and plans, and more. In general, most homeowners can expect to save somewhere between $10,000 and $30,000 over the lifetime of a solar panel system. On average, it takes between 7 and 8 years for most homeowners who shop for solar on EnergySage to get their solar panels to pay for themselves.

Going solar is one of the most effective ways to reduce or eliminate your electric bill, and you should make sure you are getting several quotes from reputable installers before you decide to move forward.
