These are averages, not offers
Every rate on this site is a statewide average: total residential revenue divided by total residential kilowatt-hours sold, as reported to the U.S. Energy Information Administration. No household is billed at this rate. It is not a tariff, not a quote, and not a price you can sign up for.
Your own rate depends on which utility serves your address, which rate schedule you are on, how much you use, when you use it, and what fixed charges and local taxes apply. In several states the variation between utilities is larger than the variation between states.
Bill estimates are arithmetic
The calculator and the running-cost tables multiply a rate by a usage figure. They exclude fixed monthly customer charges, taxes, and utility-specific riders billed as flat amounts. They assume a flat rate, so they will misstate the bill for anyone on a tiered or time-of-use schedule. Appliance consumption figures are engineering estimates for typical equipment, not measurements of your home.
Use them to decide what is worth investigating. Do not use them as a budget.
Data currency and revision
The current data period is May 2026, retrieved 2026-08-19. The EIA revises this series as utilities file corrections, and recent months should be treated as preliminary. A figure that was accurate when we published it may have been revised since.
Not professional advice
Nothing here is financial, legal, engineering or energy-procurement advice. We do not know your circumstances. If you are making a decision with real money attached, such as signing a supply contract, sizing a solar system, choosing a heating system or relocating a business, get advice from someone who can look at your actual usage and your actual tariff.
Market structure descriptions
Descriptions of which utility serves where, whether a state has retail choice, and which market a state sits in reflect our understanding as of the retrieval date. Utility territories, ownership and regulatory frameworks change. Verify anything you intend to rely on against your state's public utility commission.
No relationship with utilities or suppliers
We are not affiliated with, endorsed by, or compensated by any utility, retail energy provider, broker, installer or regulator named on this site. Utility and company names are used for identification only.
