Tesla Model Y Charging Cost

Cost by Trim, 2026 Lineup

Tesla reshuffled the Model Y range through the 2026 model year: the entry car was launched as the Standard and later became simply Model Y, the old Long Range trims became Premium RWD and Premium AWD, and a Performance sits above them. Tesla does not publish battery capacity, so the pack figures below are the usable capacities consistently reported by independent testers, and consumption is the EPA combined figure measured at the wall. Notice what the table does and does not say. Full-charge cost barely moves between Premium trims, because they share a pack. Cost per mile moves by 25% across the range, because that is a function of consumption, not capacity. The Performance costs a quarter more per mile than the entry RWD car for the same journey, and almost all of that comes from wheels, tyres and a second motor rather than anything about the battery.

What a Supercharger Stop Actually Costs

Nobody charges a Model Y from empty on a road trip. The window that matters is 10% to 80%, because Tesla’s charging curve tapers hard above 80% and the last fifth of the pack takes as long as the first two-thirds. That fourth row is the one worth internalising. Tesla rates the Premium RWD at up to 182 miles of range added in fifteen minutes at a constant 65 mph. That is an average of roughly 164 kW sustained across the session — genuinely quick — and it costs about $15.52 off-peak. Two of those stops covers 364 miles of driving for $31, which is the practical shape of a Model Y road trip.

Your Rate Matters More Than Your Trim

The Model Y’s efficiency is genuinely good — Edmunds measured 22.8 kWh/100 miles on the entry RWD car in its own range test, beating the EPA figure. But no efficiency advantage in the class survives a four-fold difference in electricity price. A Hawaii owner pays more to fill a Model Y at home than a California owner pays on a Supercharger. That is not a criticism of the car; it is a reminder that the fuel cost of an EV is a utility-tariff question first and a vehicle question second. In every state, home charging still beats the gas crossover — but the size of the win ranges from $1,560 a year to $222.

Home Charging Setup for a Model Y

The Model Y accepts up to 11.5 kW on AC, which is the number that decides what hardware makes sense. For most Model Y owners a 32-amp outlet is genuinely sufficient: eleven hours restores the pack from empty, and nobody arrives home empty. The 48-amp Wall Connector earns its extra cost in two situations — a short overnight window, or a second EV sharing the circuit. Hardware runs $300 to $700 and a straightforward install $400 to $1,500, with most homeowners landing near $1,200 all-in. Panel work is what breaks budgets, so insist on a load calculation before comparing quotes.

Five Habits That Change Your Model Y Bill

Battery Warranty and What Degradation Costs You

Tesla warrants the Model Y battery and drive unit for 8 years or 120,000 miles, whichever comes first, with a minimum 70% capacity retention over that period. That figure sets the floor, not the expectation: real-world fleet data puts modern liquid-cooled packs around 2%–2.3% capacity loss per year, so a Model Y is far more likely to be near 80% at year eight than at the 70% warranty threshold. Degradation does not raise your cost per kWh, and this is a point that gets muddled constantly. Electricity costs the same. What changes is that the same trip needs more charging events, and on a road trip that means more stops. A Premium RWD at 85% state of health has roughly 66 kWh usable and about 303 EPA-equivalent miles instead of 357 — still comfortable for daily use, slightly more annoying on a 600-mile drive.
