How the appliance cost calculator works

Convert watts to kilowatts, multiply by daily hours and your rate, then scale to monthly and yearly costs.

Method and assumptions

Energy cost is estimated by multiplying kilowatts by hours used and your electricity rate. The calculation runs in your browser.

  • Wattage, hours used, and the electricity rate stay constant for the period.
  • Fixed charges, time-of-use pricing, taxes, and changing power draw are excluded unless entered separately.
  • For better accuracy, use the appliance label and the rate on your latest utility bill.
