About this rate
This page uses the latest available EIA statewide residential average as a starting point. Your actual electricity price can be different because of your utility, plan, taxes, fixed charges, usage tiers, season and time-of-use pricing. For the best estimate, replace the rate in the calculator with the cents-per-kWh value from your own bill.
