How much does it cost to charge a Tesla Model 3 in Texas?

Texas' 12-month average rate, 16.0¢/kWh, is 11% below the U.S. average of 18.0¢/kWh, which saves $0.50 per 100 miles compared with the national rate.

Rates in Texas are rising: the latest 12-month average is 4.8% higher than in the 12 months before.

Over the last 24 months Texas was cheapest in winter and most expensive in spring: January 2025 at 14.6¢/kWh and April 2026 at 17.0¢/kWh, which moves the Tesla Model 3's monthly charging cost between $36 and $42. The latest published month, August 2026, came in at 15.9¢/kWh, in line with the 12-month average.

Of the 5 states covered so far, Texas ranks 3rd cheapest for the Tesla Model 3. It costs least in Washington ($3.45 per 100 miles) and most in California ($7.86).

Among the 10 EVs on OutletBill, the Tesla Model 3 is the 1st cheapest to charge per mile in Texas; the next cheapest, the Tesla Model Y, costs $4.39 per 100 miles.

At 24.3 kWh per 100 miles, the 2026 Tesla Model 3 Standard RWD is among the most efficient EVs EPA has rated for 2026: it uses less energy than 99% of the 321 2026 EV versions tested.

Across all 5 trims of the 2026 Model 3, cost per 100 miles in Texas ranges from $3.88 for the Standard RWD to $4.83 for the Performance AWD, a difference of $116 a year at 1,016 miles a month.

EPA estimates 12 hours to charge the Model 3 Standard RWD from empty on a 240-volt Level 2 home charger, longer than a typical night, though a full charge is rarely needed. At 1,016 miles a month (about 33 miles a day), a day's driving takes roughly 1.5 hours on a Level 2 charger.

Electricity would have to cost more than 40.3¢/kWh, 2.5 times Texas' rate, before the Tesla Model 3 cost more per mile than the 2026 Honda Accord. Put the other way, gas would have to fall below $1.24 a gallon.

Gas costs use EIA's Texas retail average for regular gasoline ($3.14 a gallon over the same 12 months, 13% below the U.S. average of $3.61) and the 2026 Honda Accord's EPA rating of 32 mpg combined.
