Formula

How it works

  • kWh per month = the sum over all appliances of watts ÷ 1,000 × hours per day × 30
  • Estimated bill (energy) = kWh per month × your state's rate
  • Difference = estimated bill − your state's average monthly bill (EIA)

Every calculator on Home Kilowatt has an "Add to my bill" button. This page collects those results, lets you add anything else by watts and hours, and applies your state's rate. It then puts your total next to the average residential bill in your state from the EIA, so you can see whether your appliance list explains your bill or something is missing. Your list stays in this browser. There's no account.

Worked example

A worked example

A Texas home running a 3,500 W central AC for 8 hours, a 1,600 W pool pump for 8 hours and a 500 W dehumidifier for 10 hours uses 1,374 kWh a month. At 15.5¢/kWh the energy comes to an estimated $212.97. The average Texas residential bill is $175.00, so this list alone is $37.97 above the average.

Questions

FAQ

What is the average electric bill in my state?

Pick your state above: the page shows the EIA average monthly residential bill next to your estimate. In our reference data the US average is $140 a month; Texas is $175 and California is $160.

Why is my bill higher than this estimate?

Three usual reasons: fixed customer charges and taxes that don't depend on use, tiered or time-of-use pricing that charges more at peak hours, and electric heating or other big loads you haven't added. Add the missing appliances, or enter the rate from your bill.

Where should I look first to lower my electric bill?

Sort your list by monthly cost. In most homes, heating, cooling and water heating are the biggest lines. Each calculator's Compare mode shows what a different setting or appliance would cost at your rate. We show estimates; we can't promise a specific saving.

Is my list saved?

Yes, in this browser only (local storage). Nothing is sent to us, and clearing your browser data clears the list.
