Why Most EV vs. Gas Comparisons Get It Wrong
The internet is full of EV vs. gas comparisons — almost all of which reach a predetermined conclusion. Pro-EV articles use high gas prices, high mileage, full credits, and home charging rates. Anti-EV articles use low mileage, public charging rates, and ignore maintenance savings. Neither approach is useful for making a real purchasing decision.
A rigorous comparison requires seven cost categories modeled side by side: purchase price (adjusted for all applicable credits), financing cost (same loan terms for both vehicles), depreciation (which varies by vehicle type and year), annual fuel cost (based on actual driving patterns and local energy prices), annual maintenance (where EVs have a genuine structural advantage), insurance (where EVs often have a modest disadvantage), and resale value (which affects the true total cost of a vehicle you'll eventually sell).
The Electric vs Gas Calculator runs all seven categories simultaneously for the specific vehicles you're comparing, over your planned ownership period, with your local energy prices. The output is a year-by-year cumulative cost comparison and a winner determination with the dollar-figure advantage — not a generic answer, but your specific answer.

Compare EV vs GasEV vs Gas: 7 Cost Categories Compared
- 1
Purchase price: the credit changes everything
The sticker price gap between an EV and its gas equivalent is typically $5,000–15,000 for mainstream vehicles. After the federal EV tax credit (up to $7,500 for eligible new EVs, $4,000 for used) and any state credits, this gap often narrows to $0–8,000. Add $1,000 for a home charging installation. The net upfront premium is the number you need to recover through savings — not the sticker price difference. In markets where EV stickers are close to gas equivalents (Chevy Equinox EV vs Equinox gas, for example), the credit can make the EV cheaper outright on purchase.
- 2
Financing: same terms, proportional to price
Financing cost scales with the loan amount. At the same interest rate and term, the more expensive vehicle costs more to finance — proportional to the price difference. If the EV costs $8,000 more at 7.2% over 60 months, the additional interest is approximately $1,500. This is a real cost that affects total ownership — though often smaller than people assume relative to the fuel savings differential.
- 3
Depreciation: the great equalizer
Depreciation is now roughly comparable between mainstream EVs and equivalent gas vehicles in most segments. Early EVs (2018–2020) depreciated faster as newer, longer-range models arrived. Recent mainstream EVs (2022+) are holding value comparably to gas equivalents. The exception: luxury and high-end EVs still depreciate faster than comparable luxury gas vehicles. Check current residual values for the specific models you're comparing — generic depreciation assumptions can meaningfully skew the result.
- 4
Fuel cost: the EV's biggest advantage
At average US prices, electricity costs approximately 3–4× less per mile than gasoline. For 12,000 miles/year, the annual fuel cost is approximately $480 for an EV (home charging, $0.14/kWh, 3.5 mi/kWh) versus $1,400 for a 30 MPG gas car at $3.50/gallon — a $920 annual saving. This advantage grows with mileage and narrows with higher electricity rates or lower gas prices. The fuel savings is the most volatile component because it tracks gas prices, which can swing $1.00+/gallon in a year.
- 5
Maintenance: EVs have a structural, durable advantage
EV maintenance savings are not a marketing claim — they're a result of a mechanically simpler drivetrain. EVs have no oil, no transmission, no spark plugs, no timing belt, and significantly reduced brake wear through regenerative braking. Consumer Reports data and fleet operator data consistently show EV maintenance costs running 30–40% below comparable gas vehicles. For most comparisons, the annual maintenance saving runs $600–900, contributing $4,200–6,300 to the EV's total cost advantage over 7 years.
- 6
Insurance: gas vehicles have a modest advantage
EVs typically cost 15–25% more to insure than comparable gas vehicles. The reasons: higher repair costs when batteries or complex electronics are damaged, lower supply of certified EV repair shops, and higher replacement part costs. For a $45,000 EV vs a $32,000 gas car, the insurance premium difference might be $300–500/year. This partially offsets the maintenance advantage. The gap is narrowing as insurers develop better EV data and repair networks expand.
- 7
Resale value: converging, but model-specific
EV resale values are highly model-specific. Tesla Model 3 and Y have held value comparably to top gas alternatives in recent years. Some GM and Ford EV models have depreciated faster due to software and charging reliability concerns in the used market. Research the specific resale value trajectory of the models you're comparing — generic EV depreciation assumptions are particularly unreliable because the market is evolving rapidly and model-specific reputation matters enormously.

The Scenarios Where Each Wins Clearly
EV wins clearly when: you drive 15,000+ miles/year, have home charging at normal residential rates ($0.14–0.18/kWh), qualify for the federal tax credit, plan to own 7+ years, and are comparing vehicles where the EV and gas price gap is under $8,000 after credits. Under these conditions, 7-year total ownership cost typically favors the EV by $8,000–20,000.
Gas wins clearly when: you drive under 8,000 miles/year, rely primarily on public charging at $0.30+/kWh, don't qualify for the tax credit (income above limits or vehicle price above caps), plan to own only 3–4 years, or the EV price premium exceeds $12,000 after credits. Under these conditions, the gas vehicle's lower upfront cost rarely gets overcome by fuel savings in the relevant ownership window.
The middle ground — where the calculator's specific numbers matter most — is the large territory in between: 10,000–14,000 miles/year, mixed home/public charging, partial credit eligibility, and 5–7 year planned ownership. This is where running your actual numbers produces a meaningfully different answer than any national average comparison.
Frequently Asked Questions
Is it worth switching from gas to electric right now?
+
For most drivers who own their home, drive 12,000+ miles/year, and qualify for the federal credit, the financial case for EVs in 2024–2026 is stronger than it has ever been. The credit can make the effective purchase price comparable to gas equivalents, while fuel and maintenance savings accumulate immediately. For renters without home charging, the calculation is much less favorable. The right answer depends on your specific situation — use the calculator with your actual numbers.
How do hybrid cars compare to both EVs and gas cars?
+
Plug-in hybrids (PHEVs) occupy a middle position: lower upfront cost than full EVs, better fuel economy than gas, and up to $7,500 federal credit for qualifying models. For short daily commuters (under 30–40 miles/day) who can charge at home, a PHEV often provides 70–80% of EV fuel savings at a smaller price premium. Standard hybrids (Toyota Prius, Honda Accord Hybrid) don't qualify for the credit but typically have lower maintenance cost than comparable gas cars and significantly better fuel economy. They're worth including in any comparison.
Does it matter which EV model I buy?
+
Significantly. Reliability, resale value, software quality, charging network access, and real-world efficiency vary substantially between manufacturers. Tesla has the most developed charging network (now open to non-Tesla EVs at many locations). Toyota and Honda have reputations for reliability that buyers reasonably project onto their EV models. Some early GM and Ford EV models had software and reliability issues that depressed resale values in the used market. Model-specific research (Consumer Reports reliability data, owner forums) is important — don't generalize from 'EVs are reliable' without checking the specific model.
What happens to the comparison if gas prices spike to $5/gallon?
+
At $5/gallon, EV fuel savings approximately double for gas prices compared to $2.50/gallon. At 12,000 miles/year and 30 MPG, annual gas cost rises from $1,000 to $2,000 while EV charging cost stays at $480 — savings increase from $520/year to $1,520/year. This accelerates EV break-even from year 6 to year 2.5 on a $6,000 net premium. Gas price spikes significantly improve the EV financial case and are one of the strongest arguments for EV ownership as a form of fuel price insurance.
