EV vs. Gas Car: Full 10-Year Cost of Ownership Compared
The sticker price is just the beginning. When you spread ownership over a decade, electric vehicles and gasoline cars trade advantages in ways that surprise most buyers. Purchase price, fuel, insurance, routine maintenance, depreciation, and federal tax credits all move in different directions — and the gap between them depends heavily on how you drive, where you charge, and which models you compare. This article walks through each cost category using data from sources like the U.S. Department of Energy's Alternative Fuels Data Center, the Bureau of Transportation Statistics, Consumer Reports' owner-survey data, and Kelley Blue Book depreciation studies, so you can see exactly where the numbers come from and apply them to your own situation.
Starting Point: Purchase Price and Financing Costs
The average transaction price for a new electric vehicle has been higher than a comparable gasoline model, though the gap is narrowing. As of recent model years, the average new EV transaction price sits roughly $5,000–$10,000 above a comparable gas vehicle in the same segment, though mass-market EVs like the Chevrolet Equinox EV and Tesla Model 3 have pushed entry points closer to $30,000–$35,000 before incentives.
Financing amplifies price differences. On a 60-month loan, a $10,000 higher purchase price at 7% APR adds roughly $200 per month and about $2,000 in additional interest over the loan term. That $12,000 all-in difference is the hole an EV owner needs to dig out of through savings elsewhere. Our gas vs. electric calculator lets you model this with your actual loan terms.

Federal Tax Credits and State Incentives
The Inflation Reduction Act extended and restructured the federal EV tax credit. Eligible new EVs can qualify for up to $7,500, and used EVs priced under $25,000 may qualify for up to $4,000. However, income caps, MSRP limits, and battery sourcing requirements mean not every buyer or every vehicle qualifies — always verify eligibility at fueleconomy.gov before assuming the credit applies.
Many states layer additional rebates on top of the federal credit — ranging from $1,000 to $7,500 depending on the state. Utility companies in some regions offer further rebates or discounted off-peak charging rates. Applied at purchase, a full $7,500 federal credit effectively closes most or all of the initial price gap between an EV and a gas equivalent, making year-one net cost competitive even before fuel and maintenance savings begin.
Fuel Costs Over 10 Years
Fuel is where EVs build their strongest long-term case. The U.S. Department of Energy's eGallon metric — which converts the cost of electricity needed to drive the same distance as a gallon of gas — consistently shows electricity costing 40%–60% less per mile than gasoline. Assuming 15,000 miles per year over 10 years (150,000 miles total):
- Gas car (30 MPG average): 5,000 gallons × $3.50/gallon average = ~$17,500 in fuel
- EV (3.5 miles/kWh average): ~42,857 kWh × $0.16/kWh national average = ~$6,857 in electricity
That's a ~$10,600 fuel savings over the decade, though your actual savings depend on local electricity rates, whether you charge at home or public stations (public charging is significantly more expensive), and whether gas prices rise or fall. Home charging on a Level 2 charger is consistently the most cost-effective option.
The DOE's Alternative Fuels Data Center and EIA monthly electricity and fuel price reports are the most reliable ongoing sources for these figures.
Maintenance and Repair Costs
EVs have fundamentally fewer moving parts than internal combustion vehicles: no oil changes, no transmission fluid, no spark plugs, no timing belts, and regenerative braking reduces brake wear significantly. Consumer Reports' annual owner surveys have consistently found EV owners reporting lower maintenance costs — roughly 30%–40% less per year on average compared to gas vehicle owners.
Over 10 years at 15,000 miles/year, typical maintenance cost estimates look like this:
- Gas car: Oil changes, filters, spark plugs, brake work, transmission service — roughly $800–$1,200/year, totaling $8,000–$12,000 over a decade
- EV: Tire rotations, cabin air filters, brake fluid checks, wiper blades — roughly $300–$500/year, totaling $3,000–$5,000 over a decade
One significant caveat: Battery replacement, while uncommon within 10 years for modern EVs, can cost $10,000–$20,000 if needed outside warranty. Most manufacturers offer 8-year/100,000-mile battery warranties, so buying within warranty coverage provides meaningful protection.
Insurance Costs
Insurance is one area where EVs have historically cost more. EV repairs involve specialized parts and certified technicians, and higher vehicle values mean higher collision and comprehensive premiums. Industry data from sources like the Insurance Institute for Highway Safety and insurer rate filings suggests EV owners pay 10%–25% more for full coverage on average than comparable gas vehicle owners.
On a vehicle with $1,500/year full-coverage premiums, that's an additional $150–$375 per year — or $1,500–$3,750 over 10 years. This gap is narrowing as EV repair networks expand and insurers gather more actuarial data, but it remains a real offset to fuel and maintenance savings that buyers should quote before purchasing.
Depreciation: The Biggest Wildcard
Depreciation is typically the largest single cost of vehicle ownership, and it's the least predictable for EVs. Kelley Blue Book and iSeeCars depreciation studies show that EV depreciation has varied widely by brand and model. Some EVs — particularly Tesla models — have held value better than most gas vehicles. Others, especially earlier-generation models and some non-Tesla brands, have depreciated 50%–60% in five years.
A vehicle that depreciates 50% over 10 years on a $45,000 purchase loses $22,500 in value. A gas vehicle at $35,000 depreciating 55% loses $19,250. The net depreciation difference in this example favors the gas car despite the higher absolute depreciation rate on the cheaper vehicle. This is why total cost of ownership comparisons must always be model-specific, not segment-generic.
Practical guidance: Check iSeeCars.com's depreciation data and KBB's 5-year cost-to-own tool for the specific models you're comparing — aggregate averages mask enormous variation between models.
Putting It Together: 10-Year Totals
Using the mid-range estimates above on a representative comparison (a $42,000 EV vs. a $34,000 gas car, both financed at 7% over 60 months, 15,000 miles/year, national average fuel/electricity costs):
- Net purchase price after $7,500 federal credit: EV $34,500 vs. gas $34,000 — nearly equal
- 10-year fuel cost: EV ~$6,900 vs. gas ~$17,500 — EV saves ~$10,600
- 10-year maintenance: EV ~$4,000 vs. gas ~$10,000 — EV saves ~$6,000
- 10-year insurance premium difference: EV costs ~$2,500 more
- Depreciation: Highly model-dependent; assume roughly equal for this illustration
Rough 10-year EV advantage (pre-depreciation): ~$14,000 — enough to justify the switch for most buyers who qualify for the full credit and charge primarily at home. The advantage shrinks considerably if you rely on public DC fast charging, don't qualify for tax credits, or choose a model with poor resale history.
Frequently asked questions
Where can I find reliable, ongoing data on EV vs. gas car total cost of ownership?
The U.S. Department of Energy's Alternative Fuels Data Center (afdc.energy.gov) and fueleconomy.gov publish regular fuel cost comparisons and the eGallon metric. Consumer Reports' annual auto reliability and owner cost surveys provide maintenance data, while Kelley Blue Book and iSeeCars publish ongoing depreciation studies. Using multiple sources gives you the most complete picture.
Does the $7,500 federal EV tax credit apply to everyone?
No. The credit has income limits ($150,000 for single filers, $300,000 for joint filers for new EVs), MSRP caps ($55,000 for cars, $80,000 for SUVs and trucks), and battery and mineral sourcing requirements that disqualify some popular models. Always verify eligibility for your specific vehicle at fueleconomy.gov before factoring it into your budget.
Is public charging expensive compared to home charging?
Significantly more expensive in most cases. Home Level 2 charging typically costs $0.13–$0.20 per kWh depending on your utility rate, while DC fast chargers at public networks often charge $0.30–$0.50 per kWh or more. EV owners who rely primarily on public fast charging can see their fuel savings cut by 40%–60% compared to those who charge mostly at home.
What happens if an EV battery needs replacement within 10 years?
Most EV manufacturers offer an 8-year/100,000-mile battery warranty that covers degradation below a specified capacity threshold (usually 70%–80%). Full replacement outside warranty can cost $10,000–$20,000 depending on the vehicle. Buying a vehicle still under its battery warranty and checking the battery health report at purchase significantly reduces this risk.
Are these cost comparisons the same for used EVs and used gas cars?
The general categories apply, but the numbers shift. Used EVs may not qualify for the used EV credit unless priced under $25,000, and battery age becomes a more significant factor in both maintenance and depreciation.
