How much electricity does a dishwasher use?
In U.S. homes that have one, a dishwasher uses about 112 kWh a year, or 9 kWh a month. At the 2025 average residential price of 17.2¢ per kWh that is $19 a year or $1.61 a month. These are EIA estimates from its Residential Energy Consumption Survey of homes and their utility bills, not a manufacturer's label.
What decides the number
Homes with a dishwasher used 112 kWh a year for the machine, including its own water booster heater and drying. The hot water it draws from the water heater is counted separately. Air-drying instead of heated drying lowers the number further.
