Laundry is a weekly chore for most households, and the combined cost of running a washer and dryer can add up quickly. Understanding how much each appliance costs to operate—and how different models compare—helps you choose wisely and adopt habits that trim your bills.

Washing Machine Energy and Water Use

Washing machines typically use 350–500 watts during a cycle. The real energy cost, however, often comes from heating the water. About 90% of a washer's energy goes to heating water when you use warm or hot settings. Switching to cold water for most loads can cut washing costs by 80% or more.

Front-Load vs. Top-Load

Front-load washers generally use less water and energy than traditional top-load agitators. High-efficiency (HE) top-loaders with impellers are closer to front-load efficiency. Energy Star certified washers use about 25% less energy and 40% less water than standard models.

Quick Fact: Running 5 loads per week with cold water instead of hot can save $60–$100 per year on electricity, plus reduce water heating costs if you have an electric water heater.

Dryer Energy Consumption

Electric dryers are the real energy hogs. They typically draw 1,800–5,000 watts and run for 30–60 minutes per load. At 3,000 watts for 45 minutes, one load uses about 2.25 kWh—roughly $0.27 at $0.12/kWh. Five loads per week adds up to $15–$25 per month.

Electric vs. Gas Dryers

Gas dryers use natural gas for heat but still need electricity for the drum motor and controls (about 300–500 watts). They're often cheaper to run than electric dryers where gas is affordable. If you're replacing an electric dryer and have gas available, a gas model can cut drying costs significantly.

Ways to Reduce Laundry Costs

  • Use cold water: Modern detergents work well in cold water for most loads.
  • Run full loads: Washers and dryers use similar energy whether half or full.
  • Clean the lint trap: A clogged lint screen makes the dryer work harder and longer.
  • Air-dry when possible: Hanging clothes saves 100% of dryer energy.
  • Choose high spin speed: Less moisture means shorter drying time.
"The dryer is often the second-most expensive appliance to run after HVAC. Air-drying even half your loads can cut your laundry electricity bill in half."

Estimating Your Laundry Bill

Use ElectriBill's calculator to estimate your washer and dryer costs. Enter wattage (washer ~400W, dryer ~3,000W), estimate hours per week (e.g., 2 hours dryer time), and your rate. You'll see how laundry contributes to your monthly electricity bill.
