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 $0.085 for firm service.
    • An off-peak water-heating rate of $0.065 a kilowatt-hour.
    • An off-peak heating rate of $0.045 a kilowatt-hour.
  • Your actual price may vary by your state, season, and rate.
  • All cost calculations are rounded to the nearest $.01.

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
