Electrical energy savings calculator

    • How do you calculate energy savings?

      Total energy savings is figured out in total kilowatt-hours, or kWh –– the measurement your utility company uses to track your energy consumption. We will divide by 1,000 to convert watts saved to kilowatts saved so the energy calculation is easier.

    • How does the electricity cost calculator work?

      How an Electricity Cost Calculator Works An electricity cost calculator is pretty straightforward, but it cuts down on a lot of the work needed to estimate energy expenses. With some electricity calculators, all you have to do is select the items you want to include in the estimate and the calculator will start crunching the numbers.

    • How much electricity do all your appliances use?
