With gasoline prices climbing in parts of the country and federal purchase incentives now off the table, more American drivers are asking a practical question: at what point does trading in a functioning gas-powered vehicle for an electric one actually make financial sense?
The answer depends heavily on individual circumstances — but a detailed cost comparison using one Arizona driver’s real numbers offers a useful framework for anyone weighing the decision.
The Question Behind the Numbers
Guadalupe Higuera, a 30-year-old software developer in Phoenix, purchased a 2025 Chevrolet Equinox EV to replace a 2016 Jeep Wrangler he had owned outright. His family runs an auto repair business, so he was raised with the practical mindset that a car worth fixing is a car worth keeping. That background made him genuinely uncertain whether the switch had been wise — even after he made it.
Higuera drives roughly 21,300 miles per year, far above the national average, with a commute of about 35 miles each way. His Jeep averaged around 20 miles per gallon. Those two factors — high mileage and low fuel efficiency — are central to understanding why his switch penciled out.
What the Calculator Showed
Using a U.S. Department of Energy cost calculator that accounts for fuel, tires, maintenance, insurance, registration, and loan payments, Higuera’s situation was modeled against real local data. He entered the Maricopa County gas price from AAA — $4.95 per gallon as of early May — along with Arizona electricity rates and his actual driving habits, which skewed about 60% highway and 40% city.
For the Jeep, the starting cost was set at zero, since he already owned it. For the Equinox, the effective purchase price was calculated at roughly $23,000 — the $45,500 sticker price minus a $7,500 federal tax credit he claimed before Congress eliminated the subsidy, and $15,000 from selling the Jeep.
The results showed first-year ownership costs of approximately $10,456 for the EV versus $8,000 to continue operating the Jeep. That gap, however, narrows steadily. By year five, the cumulative cost difference shrinks to roughly $1,000. After that point, the Equinox becomes the cheaper vehicle to own and operate on an ongoing basis.
“This makes me feel a little bit happier, financially-wise,” Higuera said of the results, noting he hadn’t anticipated the costs would converge so closely before the EV pulled ahead.
By the Numbers
$7,500 — the federal EV tax credit Higuera used, which Congress has since ended
21,300 — miles Higuera drives annually, about 9,000 more than the average U.S. driver
20 mpg — average fuel economy of his previous Jeep Wrangler
12.8 years — the current average age of cars and light trucks on American roads, according to federal transportation data
Year 5 — the point at which cumulative EV ownership costs are projected to fall below those of keeping the Jeep
Why This Math Won’t Work for Everyone
Several conditions made Higuera’s calculation favorable that won’t apply universally. His high annual mileage amplifies fuel savings. His prior vehicle’s poor gas mileage created a large cost gap that electricity can close. And critically, he secured the $7,500 credit before it was eliminated — a factor that meaningfully shifted his effective purchase price.
A driver replacing a fuel-efficient hybrid, such as a Toyota Prius averaging over 50 miles per gallon, would see a dramatically different outcome. With lower gas expenditures to offset, the cost crossover point would arrive much later, if at all.
Insurance costs also run higher for EVs, partly because components like battery packs are expensive to replace. And the calculator used does not account for depreciation — a newer vehicle loses value faster than a 10-year-old car already well into its depreciation curve. Researchers at Carnegie Mellon University note that factoring in resale value introduces additional uncertainty into five-year projections.
The Climate Dimension
On the question of reducing carbon emissions, analysts are more definitive: switching to an EV produces a clear reduction in greenhouse gas output over the vehicle’s lifetime, regardless of the financial calculus. For drivers whose decision involves both environmental and economic goals, the two objectives may point in the same direction — but the financial case requires more careful case-by-case analysis.
Georgia drivers considering the switch should also note that electricity rates vary significantly by state and utility. Georgia Power recently received regulatory approval for a rate adjustment beginning June 1, which could affect the fuel-cost side of any similar calculation run by Georgia residents.
What’s Next
With federal EV incentives now eliminated, prospective buyers have fewer tools to offset the higher upfront cost of electric vehicles. Automakers have responded by introducing lower-priced EV models, and some state-level incentive programs remain in place. Drivers evaluating the switch are advised to run calculations using their own mileage, local electricity and gas prices, and the specific vehicles under consideration — since the break-even point shifts considerably depending on individual circumstances.
