Tesla Model 3 Cost of Ownership: A 5-8 Year Reality Check vs a Gas Sedan

The Tesla Model 3 looks cheap to run on paper, but the real Tesla Model 3 cost of ownership depends on more than the sticker price. Over five to eight years, the gap between a Model 3 and a comparable gas sedan comes down to four levers: how much you drive, what you pay for electricity versus gas, insurance, and depreciation. Here is how those numbers actually stack up in 2026, with the recent rule changes that quietly reshaped the math.

Where the Model 3 starts

The Model 3 Standard RWD lists around $36,990 with roughly 321 miles of range and an efficiency near 243 Wh/mi. Step up to the Model 3 Premium RWD and you are closer to $42,490. A directly comparable gas sedan — think a well-equipped midsize — tends to land in the high-$20,000s to mid-$30,000s, so the Model 3 usually starts at a price premium. That premium is the hole the running-cost savings need to fill over your ownership horizon.

One change worth stating plainly: the federal $7,500 EV tax credit ended on September 30, 2025. Buyers today do not get it. If you have read older ownership comparisons, mentally delete that $7,500 — it no longer offsets the Model 3's higher starting price. Our Tesla vs gas cost calculator defaults this incentive to $0 for exactly that reason.

Charging vs gas: the savings engine

This is where the Model 3 earns its keep. At a Texas residential rate near $0.154/kWh and an efficiency of 243 Wh/mi, home charging costs roughly 3.7 cents per mile. A gas sedan getting around 32 mpg on $3.42/gal gas costs about 10.7 cents per mile. Over the US-average 13,500 miles a year, that is roughly $500 in home electricity versus about $1,440 in gas — close to $950 saved annually, or somewhere near $5,000-$7,500 across a 5-8 year hold if you charge mostly at home.

The caveat: Supercharging at around $0.42/kWh erases much of that edge, pushing your per-mile energy cost above 10 cents — roughly gas-equivalent. If you live in an apartment without a home plug and rely on public DC fast charging, the Model 3's charging advantage shrinks dramatically. Honest ownership math means modeling your real charging mix, not the best case.

Insurance, maintenance, and the Texas EV fee

Maintenance favors the Model 3 clearly: about $0.031/mi versus roughly $0.061/mi for a gas car — no oil changes, fewer fluids, and regenerative braking that spares the brake pads. Over 13,500 miles, that is around $400 saved per year, or $2,000-$3,200 over the hold.

Insurance pushes the other way. EVs — and Teslas specifically — tend to run about 25% more to insure than a comparable gas sedan, driven by repair costs and parts availability. On a typical premium that can mean a few hundred dollars more each year, partially offsetting the maintenance win.

Texas owners face one extra line item gas drivers never see: a $400 EV registration surcharge at purchase plus $200 every year after. Across eight years that is roughly $1,800 in fees designed to recover lost gas-tax revenue. It does not break the case for the Model 3, but it does eat into the energy savings, especially for low-mileage drivers.

Depreciation: the biggest number nobody budgets for

Depreciation usually dwarfs fuel and maintenance combined. A Tesla holds value reasonably well — about 40% lost over five years — versus roughly 45% for an average gas car. On a $37,000 Model 3, a 40% drop is about $14,800 of value gone in five years. The percentage edge helps Tesla, but because the Model 3 starts higher, the dollar loss can still be comparable to a cheaper gas sedan losing a larger percentage of a smaller number. Either way, new cars shed the most in year one, so an 8-year hold spreads that hit over far more miles and lowers your true cost per mile.

So who actually comes out ahead?

The Model 3 tends to win for high-mileage drivers who charge at home, hold the car 6-8 years, and value lower maintenance. A gas sedan can win for low-mileage buyers, apartment dwellers dependent on Supercharging, or anyone who trades cars every two or three years and absorbs steep early depreciation on a pricier vehicle. There is no universal answer — only your inputs.

If you want FSD, note it is now subscription-only at $99/month; at 8 years that is over $9,000 and can single-handedly flip the comparison, so model it deliberately rather than assuming it away.

Run your own numbers

These figures are reasonable starting points, but your electricity rate, mileage, charging mix, and how long you keep the car will move the result by thousands of dollars.
