Tesla Charging Cost in Texas: Home vs Supercharger (2026 Cents Per Mile)

The single biggest variable in what a Tesla costs to run in Texas isn't the car — it's where you plug it in. Charge at home overnight and you pay the residential electricity rate. Lean on Superchargers and you pay roughly three times as much per kilowatt-hour. This page breaks down the real cost of charging a Tesla in Texas: the home marginal rate versus Supercharger pricing, translated into cents per mile and a realistic monthly bill, so you can see where the savings actually come from.

The two rates that matter

In Texas, residential electricity runs about $0.154 per kWh on a typical retail plan — below the U.S. average of roughly $0.177. Tesla Supercharging in Texas averages around $0.42 per kWh, though it varies by site, time of day, and congestion pricing. That gap is the whole story: a Supercharged mile costs nearly the same as a gas mile, while a home-charged mile costs a fraction of it.

One adjustment matters before we convert to cents per mile. The energy you pull from the wall is higher than what reaches the wheels, because of charging and battery losses — roughly 10%. We bake that loss in below, so these are "from the wall" numbers, not optimistic spec-sheet figures.

Cents per mile by Tesla model

Using EPA-rated efficiency plus a 10% charging loss, here's what each mile costs at home versus on a Supercharger in Texas:

• Model 3 Standard RWD (~243 Wh/mi): about 4.1¢/mi at home vs 11.2¢/mi Supercharging.
• Model Y Long Range AWD (~275 Wh/mi): about 4.7¢/mi at home vs 12.7¢/mi Supercharging.
• Cybertruck AWD (~429 Wh/mi, the least efficient Tesla): about 7.3¢/mi at home vs 19.8¢/mi Supercharging.

For context, a gas crossover getting 30 MPG at Texas's ~$3.42/gal regular costs about 11.4¢ per mile in fuel alone. That's the key takeaway: a Supercharged Model Y is roughly a wash with gas on energy cost, but a home-charged Model Y is less than half. The EV advantage lives almost entirely in your driveway.

What that looks like monthly

The average American drives about 13,500 miles a year, or ~1,125 miles a month. For a Model Y Long Range:

• 100% home charging: roughly $52 per month (~$629/year).
• 100% Supercharging: roughly $143 per month (~$1,715/year).

Most Texans land somewhere in between. A common pattern — charge at home, Supercharge only on road trips, say 85% home and 15% Supercharger — works out to around $65–$70 a month for a Model Y. Your real number depends on your retail electricity plan, how much you road-trip, and which model you drive.

When Supercharging-only doesn't pencil out

If you live in an apartment or rent without a dedicated plug, you may charge almost entirely on Superchargers. Be honest about that before you buy. At ~$0.42/kWh, the fuel savings that make EVs cheap largely evaporate, and on energy alone a Supercharged Tesla can cost about what a comparable gas car costs to fuel. The EV still wins on maintenance — roughly $0.031/mi versus $0.061/mi for gas, with no oil changes and less brake wear thanks to regen — but charging access is the deciding factor. If you can install a home charger, the math swings hard in the Tesla's favor; if you can't, run the numbers carefully.

Beyond the plug: the rest of the Texas math

Charging is only one line item. In Texas specifically, an EV owner also pays a $400 upfront registration surcharge plus $200 every year that gas drivers don't — effectively a flat fee that offsets some of your home-charging savings. The federal $7,500 EV tax credit ended on 9/30/2025, so it's no longer part of the equation either. On the other side, Teslas tend to depreciate a bit slower than the average car (~40% vs ~45% over five years), and maintenance is cheaper. To see how charging mix, the Texas EV fee, financing, insurance, and depreciation net out over your ownership horizon, run your own numbers in the Tesla vs Gas Cost Calculator, where you can set your exact home rate and home/Supercharger split.

The bottom line

Charging a Tesla in Texas is cheap if you charge at home — roughly 4–5 cents a mile for a Model 3 or Y, or about $50–$70 a month for typical driving. It's only ordinary if you rely on Superchargers, where per-mile cost climbs close to gas. Before you assume a Tesla will slash your fuel bill, figure out where you'll actually plug in.
