How much does it cost to run a dishwasher?

A typical dishwasher uses about 1,800 watts, so it costs about 34¢ an hour to run at the U.S. average electricity price of 19.0¢ per kWh (October 2026). Used one 1-hour cycle, five times a week, that is about $6.84 a month, or $82.08 a year.

Key figures

  • 1,200–2,400 Wtypical wattage (U.S. Department of Energy)
  • 34¢per hour at 19.0¢/kWh
  • $6.84per month, used one 1-hour cycle, five times a week
  • 36.0 kWhper month at that use

A dishwasher draws most of its power while heating water and drying. The DOE notes that the heated drying feature greatly increases energy use. Running full loads and choosing air-dry instead of heated dry lowers the cost per cycle.

Running cost calculator

Cost = watts × hours ÷ 1,000 × price per kWh (the DOE formula). The wattage on your appliance’s label or in its manual gives the most accurate result; appliances that cycle on and off (heaters with a thermostat, dehumidifiers) use less than their rated wattage.
