Texas electricity cost calculator
In August 2026, households in Texas paid an average of 15.91¢ per kWh, in the middle range among the 51 states and DC (rank 30, where 1 is the most expensive). That is 12.4% below the U.S. residential average of 18.16¢. The price was higher than August 2025 (15.40¢; change +3.3%). Averaged over August 2026 year to date, the residential price was 16.03¢ versus 15.18¢ a year earlier (+5.6%). Year-to-date averages smooth out single-month swings such as summer air-conditioning peaks. In 2024 the average Texas household used 1,096 kWh a month and paid $163.72 (EIA annual data). At the August 2026 price, the same usage would cost about $174.37 in energy charges. For that amount of electricity, the Texas price means paying about $24.66 a month less than at the U.S. average price.

Questions
Why is my bill different from the state average?
The state figure is an average across all utilities and rate plans. Your bill depends on your utility, whether you have tiered or time-of-use rates, fixed monthly customer charges, taxes and fees, and how much you used in that billing period. Divide the total on your bill by the kWh used to get your own all-in price, then enter it in the calculator.
Where do I find the watts of a device?
Look for a label or plate on the back or bottom of the device, on its power adapter, or in the manual. If it lists amps and volts instead, multiply them: watts = volts × amps. Devices with thermostats or standby modes run at full power only part of the time, so actual use is often lower than the rating times hours.
How often are these prices updated?
EIA publishes Electric Power Monthly about once a month, roughly two months after the data month. This site checks for a new release automatically and rebuilds every page when one appears.
