Where the numbers come from
Each rate is the average residential price for the year to date, from the U.S. Energy Information Administration (EIA, Electric Power Monthly, Table 5.6.B). It is total residential revenue divided by kWh sold, so it already includes the fixed and delivery charges spread over each kWh.
Why your bill's rate can be different
- Your utility: rates vary between utilities in the same state.
- Your plan: time-of-use and tiered plans charge more at some hours or above a monthly amount.
- The season: many utilities charge more in summer.
To know your real rate, divide your bill's total by the kWh it shows. Use that number in the appliance cost calculator or any calculator on this site.
