2026 Tesla Model 3 Performance cost to own in Montana — the true 5-year total
The 2026 Tesla Model 3 Performance starts at $54,490. As of July 1, 2026, over 5 years, owning one (EV) costs about $63,535 in Montana — $1,059/month, $1.06/mile — including depreciation, charging (with the ~12% AC charging loss most calculators ignore), maintenance, insurance, financing and fees. That's $26,893 more than a comparable Honda Civic LX (gas) over the same 5 years. Montana's electricity (13.9¢/kWh) is 26% below the U.S. average, and gas runs $3.95/gal here — both fed straight into the numbers above. The federal $7,500 EV credit expired Sept 30, 2025 and is not applied.

The charging-loss row is the ~10–15% of electricity lost to AC charging that you pay for but never reaches the battery — we include it; most calculators don't.

What else moves your 2026 Tesla Model 3 Performance cost
The 5-year total already folds in depreciation, charging, insurance, maintenance and financing. Here's how the biggest levers work — and the ones that sit outside the total.
- Financing. Borrow the full $54,490 at a typical 7.2% new-car APR over 60 months and interest alone adds about $10,557. Lower the APR or add a down payment in the calculator and the total drops — financing is in the 5-year figure above.
- Insurance. This model averages about $2,750/yr to insure — roughly $550/yr more than a comparable gas car ($2,200/yr), as EV parts and repairs tend to cost more — our own estimate, calibrated to Insurify/Bankrate 2026, and already in the total above.
- Home charger. A Level 2 home charger is a one-time $500–$2,000 installed (depends on your panel and wiring) — not in the total above, but it pays back fast versus public fast-charging.
- Tires. EVs are heavier and make instant torque, so tires can wear ~20% faster — a real running cost most comparisons skip. We fold a higher maintenance rate for EVs into the total.
- Where you charge. Public DC fast-charging can cost 2–3× your home rate. The total assumes 80% home charging; if you can't charge at home, lower that share in the calculator to see the real cost.
2026 Tesla Model 3 Performance battery — replacement cost & lifespan
Most EVs never need a battery replacement inside the 8-year / 100,000-mile warranty, so this is not in the 5-year total above — but it's the cost buyers worry about most, so here it is transparently.
- Out-of-warranty replacement

Cost to charge the 2026 Tesla Model 3 Performance at home
The 2026 Tesla Model 3 Performance runs about $4.68 per 100 mi at home — versus about $13.16 for a typical 30 mpg gas car. Home charging only (the ~12% AC charging loss is included); public DC fast-charging is billed per session by each network — often 2–3× the home rate — and isn't in these figures.
- Per 100 mi at home
- $4.6829.6 kWh/100mi + 12% charging loss × $0.14/kWh
- A typical 30 mpg gas car
