The EV-versus-gas total cost of ownership debate has settled into received wisdom: EVs are more expensive to buy, but cheaper to operate, so they win over time. The reality is more conditional. Depreciation has been brutal on used Teslas and other EVs in 2023 and 2024. Insurance costs are noticeably higher. Battery replacement, while rare in the first decade, is a real tail risk on older vehicles. Whether the math works depends heavily on miles driven, electricity rates, garage access, and how long the buyer plans to keep the car.
Where the savings actually show up
Operating savings are real. At average U.S. residential electricity rates of around 16 cents per kWh, an EV getting 3.5 miles per kWh costs about 4.6 cents per mile in fuel — versus roughly 14 cents per mile for a 30-mpg gas vehicle at $4 gasoline. Over 15,000 annual miles, that’s a difference of about $1,400 per year. Maintenance is meaningfully lower — no oil changes, no spark plugs, less brake wear due to regenerative braking — typically saving $500 to $800 per year compared to comparable gas vehicles. For a household that drives 20,000-plus miles a year and has home charging, the operating advantage compounds quickly.
Where the costs the dealer doesn’t mention show up
Depreciation has been the EV story of 2023 and 2024. Used Tesla Model 3 prices fell roughly 30 percent in 2023 alone, dragging down the broader used EV market. Aggressive new-car price cuts from Tesla and other manufacturers reset residual values across the segment. A buyer who paid $50,000 for a new EV in 2022 and tries to trade it in 2025 may find themselves $15,000 to $20,000 underwater. Insurance is another sleeper cost — EVs cost 20 to 25 percent more to insure on average, according to Insurify and Bankrate data, due to higher repair costs, expensive sensors, and limited body shop networks. And while battery degradation has been better than feared (most EV batteries retain over 85 percent capacity at 100,000 miles), out-of-warranty replacement still runs $10,000 to $20,000 — a possibility that bites the third or fourth owner.
Who actually comes out ahead
The math works best for households that drive a lot, have home charging at residential rates (not condo or apartment), buy a moderately priced EV (not a $90,000 luxury model where depreciation is steepest), and hold the vehicle for at least 7 years. It works less well for low-mileage drivers who would benefit more from a fuel-efficient hybrid, for renters without dedicated charging, for buyers who flip cars every 3 years, and for anyone who needs frequent road trips through regions with sparse fast-charging infrastructure. Federal tax credits and state incentives change the calculus, but they’re moving targets — the 2024 IRA rules tightened sourcing requirements, eliminating credits for several previously-qualifying models.
Bottom line
EVs are a great deal for some drivers and a mediocre deal for others. The marketing case treats them as universally superior. The financial case is conditional. Run the numbers with realistic assumptions about your driving, electricity rate, holding period, and insurance — not the manufacturer’s calculator — and the answer for any given household becomes specific rather than ideological.
