Appliance Energy Use

Learn how much it costs to run typical home appliances

  • These costs are based on the average operating costs for many typical home appliances. Cost calculations are intended to be examples only and are based on:
    • A per-kilowatt-hour rate of 10.5¢ for firm service.
    • An off-peak water-heating rate of 7¢ a kilowatt-hour.
    • An off-peak heating rate of 4.5¢ a kilowatt-hour.
  • Your actual price may vary by your state, season, and rate.
  • All cost calculations are rounded to the nearest kilowatt-hour and penny.

Calculate the cost to operate any appliance

Appliance wattage ÷ 1,000 × the hours the appliance is used
× the price per kilowatt-hour of electricity = cost of operation
