Tennessee Electricity Rate and Bill Calculator

Is electricity expensive in Tennessee?

On this statewide comparison, Tennessee ranked #43 out of 51 from highest to lowest residential price, with Washington, DC included. Its 13.87¢/kWh average was 23.7% below the U.S. average of 18.19¢/kWh. That comparison is useful for location-level budgeting, but it is not a quote from a particular utility or supplier.

At 1,000 kWh per month, the average-rate energy charge is about $138.70 per month or $1,664.40 per year. A household using half as much energy would not necessarily pay half the final bill because customer charges and tier rules can remain. Use the kWh scenarios above as a transparent benchmark, then replace the rate with the one shown on your own bill for a closer estimate.

How the Tennessee rate changed

The comparable prior-period residential average was 13.22¢/kWh. The current figure is 4.9% higher. For a steady 1,000 kWh per month, that rate movement changes the modeled annual energy charge by about $78.00 more before other bill components. This is a period comparison, not a prediction: utility filings, fuel costs, weather, rate cases, and usage patterns can move future bills in either direction.

States with a similar average price

The closest statewide averages in this dataset are Montana at 13.95¢/kWh, Wyoming at 13.95¢/kWh, and Missouri at 13.96¢/kWh. Similar statewide prices do not mean households receive the same service, rate design, climate, or generation mix. This comparison answers the narrower question of which reported residential averages are numerically closest.

How to calculate an electricity bill from kWh

Convert cents to dollars, then multiply by energy use. For Tennessee, 13.87 cents becomes $0.1387 dollars per kWh. The formula is energy charge = monthly kWh × $0.1387. The calculator above performs that multiplication and updates instantly. For a fuller estimate, open the electricity bill calculator with the Tennessee rate prefilled and add a fixed daily charge, tax, or levy from your bill.

Why your actual Tennessee rate can differ

The EIA figure is an average price calculated from residential revenue and electricity sales across the state. It is not a universal tariff. Your effective price can differ because of utility territory, supplier, time-of-use periods, seasonal tiers, fuel riders, fixed customer charges, taxes, solar export credits, assistance programs, or unusually high or low consumption. Divide the usage-based portion of a recent bill by its kWh when you need a household-specific rate. Do not include unrelated one-time fees in that division.

Use this rate for appliance decisions

Saving the rate places it in this browser only; no account or location is uploaded. Compatible running-cost calculators use it as the default, and a rate included in a shared URL takes priority. Start with the appliance running-cost calculator, compare space-heater cost, or estimate EV charging cost using the same transparent assumption.

Source and update method

Rates come from the U.S. Energy Information Administration’s Electric Power Monthly table 5.6.B, “Average Price of Electricity to Ultimate Customers by End-Use Sector, by State.” The values are preliminary year-to-date residential averages for January–July 2026, released September 24, 2026. See the official EIA table, our methodology, or the all-state comparison and downloadable dataset.
