For years, Tesla buyers could count on generous federal help and cheap electricity to make the math work. Heading into 2026, that picture is more complicated, with new rules, higher power bills in some states, and falling used prices all tugging at the bottom line. The question now is not whether a Tesla is cheaper to run than a gas car in theory, but whether it still saves real money for the specific driver who signs the paperwork.
To sort that out, it helps to look past the sticker price and into the full cost of ownership: incentives, energy, maintenance, repairs, and resale. Put together, those pieces show that a Tesla can still be a smart financial move in 2026, but only if the owner’s charging setup, driving habits, and risk tolerance line up with the new reality.
Tax breaks, Trump’s OBBBA and the 2026 purchase decision
The first big swing factor in 2026 is policy. President Trump’s signature on the package known as OBBBA reshaped how federal help for electric vehicles works. Reporting on How Does Trump, OBBBA, Change EV Tax Incentives makes clear that Trump’s overhaul shifted buyers away from the simple, automatic tax credits that once shaved thousands off a new Tesla and toward a more targeted system that depends on income, vehicle price caps, and where the car is built. That means some shoppers who would have qualified for a full federal tax credit a few years ago may now get a smaller break, or none at all, when they look at a Model 3 or Model Y.
At the same time, the broader EV market is adjusting to the end of the old federal subsidy structure. One analysis of Electric car costs notes that when the federal subsidy for electric cars ended, simple math suggested sales would soften because the upfront premium over gas cars became harder to ignore. Yet separate coverage of the EV Industry Outlook for 2026 points out that demand is still expected to grow, helped by cheaper batteries and more models, even as incentives shrink. In that context, How Does Trump, OBBBA, Change EV Tax Incentives is less a death blow to Tesla economics and more a reminder that buyers now have to run their own numbers instead of assuming Washington will pick up a big chunk of the tab.
Energy costs: when charging is cheaper, and when it is not
Once a Tesla is in the driveway, the next question is what it costs to feed. For drivers in states with moderate power prices, the advantage is still clear. A California cost breakdown found that electric vehicles cost approximately $0.03 per mile to power, compared with higher per‑mile fuel costs for gas cars with typical efficiency ratings. That same analysis, labeled True Cost of Owning Gas vs Electric Car in California: 2025 Breakdown, stressed that Higher initial costs are offset by substantially lower operating expenses over time, which is exactly the kind of long game Tesla buyers are betting on.
But electricity is not cheap everywhere, and even within California the story can flip. A Tesla Model X owner in the state laid out winter off‑peak rates of $0.46 per kWh and summer off‑peak rates of $0.50 per kWh, spelling out that at $0.46 to $0.50 per kWh his Winter and Summer charging costs made his EV roughly equal to a 25‑mpg gas SUV, with net savings described as zero dollars. Another comparison of mid‑priced vehicles found that Even in California, ICE powered cars were slightly cheaper to fuel at $14.82 per 100 miles compared with an EV charged mostly at home for $16.9, showing that high residential rates can erase the fuel advantage.
Maintenance, repairs and the risk of big Tesla bills
Where Teslas still shine is routine upkeep. A widely cited analysis titled Consumer Reports Study Finds Electric Vehicle Maintenance Costs Are 50% Less Than Gas, Powered Cars found that electric drivetrains avoid many of the wear items that keep mechanics busy. A separate look at Transportation Electrification asked, Can Electric Vehicles Really Be 50% Cheaper to Maintain Than Gas, Powered Cars, and leaned on the same core idea: fewer moving parts and no oil changes mean a typical EV owner spends far less on scheduled service. Another ownership guide put a finer point on it, stating that Maintenance costs for EVs are 31% cheaper, even after factoring in slightly higher Insurance premiums.
Real‑world Tesla data backs that up, with Most Tesla owners described as spending relatively little on maintenance in the first 5 to 8 years, according to a repair guide that still warns about rare but painful events. That same Most Tesla analysis notes that collision or battery‑adjacent repairs can be prohibitively expensive, which is echoed in another comparison that says EV savings can pile up but that some repairs are often prohibitively expensive. A focused Tesla Cost and Maintenance Comparison asks, Are Teslas really as affordable as they seem, and answers that looking at the total cost, including potential bodywork and out‑of‑warranty fixes, is essential before deciding to own a Tesla, which is why that Tesla Cost and urges buyers to know What to Expect.
The used market adds another wrinkle. Coverage of falling second‑hand prices notes that Used Tesla Prices See a Major Drop, but EV Buyers Need to be aware that Repair costs could be higher since some repairs are usually more expensive on an electric car than on a gas‑powered vehicle. That Repair warning is the flip side of the bargain: a cheaper entry price into a Model 3 or Model Y can be wiped out if a battery‑related issue or complex body repair hits before the car is paid off.
Total cost of ownership: where Teslas still come out ahead
When all the pieces are added up, the long‑term math still leans in Tesla’s favor for many drivers, especially those who rack up miles and can charge cheaply at home. A detailed comparison of EVs and gas cars concluded that if we bring it all together to sum up the EV cost of ownership vs gas, it is clear that the ongoing costs to maintain and fuel an electric vehicle are lower, and that many electric vehicles maintain their value better over time. That Tenet analysis lines up with another breakdown that says Higher initial costs are offset by substantially lower operating expenses over time, and with a separate look at how EV savings can pile up, including a claim from Veloz that an EV can cost roughly 30 dollars less to fully charge than filling a gas tank.
Individual stories echo that pattern. One Tesla driver who shared a detailed cost comparison between their Model 3 and a previous gas car concluded that while fuel accounted for over 15% of overall ownership costs, the EV’s lower running expenses helped offset higher insurance and purchase price. In that account, The OP broke down real‑world spending and invited readers to Click through the numbers, showing how The OP’s experience matched broader data. A separate Substack essay titled Comparing cost of ownership: EVs vs ICE cars noted that At the time, the author knew that battery prices were declining and would likely continue doing so, and argued that instead of focusing on sticker shock, buyers should look at how the cost of electric vehicles is falling as they take a huge share of the market, a point reinforced in the At the analysis.
