What this Tesla cost-of-ownership calculator actually includes

Most "Tesla savings" calculators only compare fuel to electricity and stop there — which is exactly how you get a rosy number that real ownership never matches. This one models the full total cost of ownership (TCO) for a Tesla versus a comparable gas car, year by year, and tells you the break-even year — the point where the Tesla becomes the cheaper car to own once everything is counted.

Is this an EV vs gas calculator, or just Tesla?

Both. At heart it's an electric car vs gas cost calculator — the underlying math (cheap home electricity vs gasoline, far lower EV maintenance, state EV fees, depreciation, insurance) is the same for any electric car. Tesla is the default because it's the best-selling EV and the one most people cross-shop against a gas car, but the comparison framework is the same whatever EV you're weighing. New to the question? Start with our plain-English EV vs gas cost comparison, then run your exact numbers in the calculator above.

The line items competitors leave out

Two things this calculator does that no other one does

Real-bill charging cost. Your true cost to charge at home is the marginal rate — energy charge plus delivery charge — not a flat national average. Enter your actual rate for an honest charging number.

Time-value of maintenance. Gas cars don't just cost money to maintain — they cost hours (oil changes, inspections, waiting rooms). Turn on "value my maintenance time" to price those hours at your wage. EVs barely have any.

How break-even is calculated

We compute each vehicle's true net cost of ownership through every year: depreciation plus financing interest plus running costs (energy, maintenance, insurance, fees), minus the resale value you'd recover if you sold. The break-even year is when the Tesla's net cost drops at or below the gas car's. Because the Tesla usually costs more up front but less to run — and holds its value differently — the crossover is the number that actually matters.

Honest by design: at low mileage, with no incentives and steep first-year depreciation, a cheap efficient gas car can win — and this calculator will tell you so. See the full methodology and sources →
