What It Actually Costs to Drive a Gas Car vs. an Electric Vehicle
The real cost difference between gas and electric depends on what you drive, where you live, and how long you keep the car
A gas car costs less upfront. An EV costs less to run. The break-even point — where the EV's lower fuel and maintenance costs make up for its higher purchase price — usually happens somewhere between 5 and 10 years of ownership, but that number shifts based on your electricity rates, gas prices in your area, how many miles you drive yearly, and which specific models you're comparing.
The comparison isn't one number. It's a set of separate costs you can add up yourself: purchase price, fuel cost per mile, maintenance, insurance, and how long you plan to own the vehicle. This guide walks through each one so you can see where the money actually goes.
Key Takeaways
- EVs typically cost $5,000 to $15,000 more to buy than comparable gas cars, but that gap narrows or disappears when you factor in lower fuel and maintenance costs over five to ten years.
- Charging an EV costs roughly one-third to one-half what gas costs per mile in most U.S. regions, but your local electricity rate and the efficiency of your charger matter significantly.
- EV owners spend far less on maintenance because electric motors have fewer moving parts, no oil changes, and regenerative braking reduces brake wear.
- The total cost advantage of an EV grows the more miles you drive annually, because fuel savings compound while the purchase price stays fixed.
- Federal tax credits, state rebates, and utility incentives can reduce EV purchase price by $3,500 to $7,500, which shifts the break-even point earlier.
Purchase price: what you pay at the dealership
A new EV typically costs $5,000 to $15,000 more than a gas car in the same class. A 2024 Tesla Model 3 starts around $43,000. A 2024 Honda Accord, which is roughly the same size and performance class, starts around $28,000. That's a $15,000 gap before incentives.
The gap is smaller for luxury vehicles and larger for compact or economy cars, because EV battery packs cost the same whether the car is small or large. A $25,000 gas compact car might have an EV equivalent at $33,000, but a $60,000 gas luxury sedan might have an EV equivalent at $65,000.
Used EV prices have dropped significantly since 2022. A three-year-old EV that sold for $45,000 new might now sell for $28,000 to $32,000, depending on mileage and battery condition. Used gas cars depreciate too, but the used EV market is still volatile because battery technology and charging networks are changing faster than they are for gas engines.
Fuel cost per mile: electricity vs. gasoline
Charging an EV costs roughly $0.03 to $0.06 per mile in most U.S. regions. Driving a gas car costs roughly $0.08 to $0.12 per mile. That means an EV costs about one-third to one-half as much to fuel.
The exact number depends on three things: your local electricity rate, the efficiency of your charger, and the efficiency of the specific EV model. A Tesla Model 3 in California, where electricity costs $0.18 per kilowatt-hour, costs roughly $0.05 per mile to charge at home. The same car in Louisiana, where electricity costs $0.10 per kilowatt-hour, costs roughly $0.03 per mile. A less efficient EV or a slower charger will cost more per mile.
Public fast-charging stations cost more than home charging — typically $0.25 to $0.45 per mile — because the operator pays for the equipment and the electricity. If you charge only at home, your cost stays low. If you rely on public fast charging for long trips, your per-mile cost rises closer to gas prices.
| Scenario | Cost per mile | Annual cost (12,000 miles) |
|---|---|---|
| EV, home charging, low electricity rate | $0.03 | $360 |
| EV, home charging, high electricity rate | $0.06 | $720 |
| EV, public fast charging | $0.35 | $4,200 |
| Gas car, $3.50 per gallon, 25 mpg | $0.14 | $1,680 |
| Gas car, $3.50 per gallon, 35 mpg | $0.10 | $1,200 |
Over 12,000 miles per year — the U.S. average — an EV charged at home saves $840 to $1,320 annually compared to a gas car. Over ten years, that's $8,400 to $13,200 in fuel savings, which directly offsets the higher purchase price.
Maintenance: what you spend to keep it running
An EV has no oil changes, no transmission fluid, no spark plugs, and no timing belts. The motor has one moving part instead of hundreds. Regenerative braking means the brake pads last two to three times longer than they do on a gas car. Most EV owners spend $0.03 to $0.08 per mile on maintenance. Gas car owners typically spend $0.06 to $0.12 per mile.
Over 150,000 miles, an EV might cost $4,500 to $12,000 in maintenance. A gas car of similar age and mileage typically costs $9,000 to $18,000. The difference compounds because you're not replacing oil, filters, belts, and transmission parts on the EV schedule.
The one major maintenance item for an EV is the battery. Most EV batteries are warrantied for eight years or 100,000 miles, whichever comes first. Battery replacement costs $5,000 to $15,000 depending on the model, but most owners don't face this cost during the warranty period. After warranty expiration, battery degradation is gradual — most EVs retain 80 to 90 percent of their original range after 150,000 miles — so replacement isn't urgent unless you need maximum range.
Insurance and registration: state and insurer variation
EV insurance costs vary by state and insurer more than gas car insurance does. In some states, EVs cost 5 to 10 percent more to insure because repair shops charge more for EV-specific work and parts are less standardized. In other states, insurers offer EV discounts because accident rates are lower. On average, EV insurance runs within 5 to 15 percent of comparable gas car insurance, so the difference is smaller than fuel and maintenance savings.
Registration fees vary by state. Some states charge higher registration for EVs; others charge lower fees or waive them entirely as an incentive. A few states tie registration cost to vehicle weight or value, which means an EV might cost more or less depending on the specific model and your state's formula. Check your state's Department of Motor Vehicles website for the exact fee.
Federal tax credits and state incentives
The federal EV tax credit is up to $7,500 for new vehicles and up to $4,000 for used vehicles, but it has income limits and price caps that exclude some buyers and some vehicles. A married couple filing jointly can earn up to $320,000 and still claim the credit for a new EV. The vehicle itself must cost less than $55,000 (sedan) or $80,000 (SUV or truck). The credit phases out for higher-priced vehicles.
Many states offer additional rebates or tax credits ranging from $500 to $5,000. California, Colorado, New York, and several others have state-level incentives. Some utilities offer rebates for home charger installation, typically $300 to $1,000. These incentives reduce the effective purchase price and shift the break-even point earlier, sometimes by two to three years.
Incentives change frequently and have income or vehicle restrictions. The federal credit, for example, now requires final assembly in North America, which excludes some imported EVs. Check fueleconomy.gov and your state's energy office website for current programs and may be able to access rules.
Total cost of ownership: five-year and ten-year scenarios
A five-year comparison favors gas cars slightly, because the EV's purchase premium hasn't been fully offset by fuel and maintenance savings. A ten-year comparison favors EVs, because fuel and maintenance savings accumulate. The exact crossover depends on your local electricity and gas prices, how many miles you drive, and which models you're comparing.
Example: A buyer in a region with $0.13 per kilowatt-hour electricity and $3.50 per gallon gas, driving 12,000 miles per year, comparing a $43,000 Tesla Model 3 to a $28,000 Honda Accord. Assume no federal credit for simplicity. Over ten years: the Model 3 costs $43,000 upfront plus $7,200 in charging (12,000 miles × 10 years × $0.06 per mile) plus $6,000 in maintenance, totaling $56,200. The Accord costs $28,000 upfront plus $16,800 in gas (12,000 miles × 10 years × $0.14 per mile) plus $12,000 in maintenance, totaling $56,800. The costs are nearly identical, but the Model 3 has more range and lower operating costs in years 6 through 10.
If the same buyer qualifies for a $7,500 federal credit, the Model 3's total cost drops to $48,700 — a $8,100 advantage over ten years. If they drive 18,000 miles per year instead of 12,000, the fuel savings grow and the EV advantage increases to $15,000 or more over ten years.
When a gas car still makes financial sense
A gas car remains the lower-cost option if you drive fewer than 8,000 miles per year, plan to keep the car for three years or less, have no access to home charging, or live in a region where electricity costs nearly as much as gas. Gas cars also make sense if you tow frequently or need maximum range in remote areas without charging infrastructure.
If you drive a used gas car you already own, the math is simple: keep it until major repairs exceed the cost of replacement. Switching from a paid-off gas car to a new EV loan almost never makes financial sense unless you drive very high mileage.
Frequently Asked Questions
Do I need to factor in the cost of installing a home charger?
Yes. A Level 2 home charger costs $500 to $2,500 installed, depending on your electrical panel and how far the charger is from it. Some utilities offer $300 to $1,000 rebates. If you rent or can't install a charger, public charging costs more per mile and reduces the EV's financial advantage. Factor in the charger cost as part of your purchase decision.
What happens to the cost comparison if gas prices spike?
The EV advantage grows. If gas reaches $5 per gallon, a 25-mpg gas car costs $0.20 per mile to fuel, while an EV charged at home still costs $0.03 to $0.06 per mile. Over ten years at 12,000 miles annually, that's $16,800 in gas versus $3,600 to $7,200 in electricity — a $9,600 to $13,200 swing in the EV's favor.
Should I buy used to save money on the purchase price?
Used EVs are cheaper upfront but carry battery age and mileage. A three-year-old EV with 40,000 miles might cost $15,000 less than new, but you have only five years of warranty remaining instead of eight. Used gas cars have the same age-and-mileage tradeoff. Compare the total cost of ownership, not just the sticker price, because a cheaper used EV might have higher maintenance costs later.
Does the federal tax credit apply if I lease instead of buy?
The credit structure changed in 2024. For new leases, the credit transfers to the leasing company, which typically passes it to you as a lower monthly payment. For used vehicle leases, the credit does not apply. Leasing can lower your monthly cost if you want to avoid battery replacement risk, but it doesn't build equity the way ownership does.
How much does battery degradation affect resale value?
Most EVs retain 80 to 90 percent of their original range after 150,000 miles, which is gradual enough that resale value doesn't drop sharply until mileage exceeds 100,000. A five-year-old EV with 60,000 miles typically retains 60 to 70 percent of its original purchase price. A gas car of the same age and mileage retains roughly the same percentage, so battery age is not a unique disadvantage — it's factored into the used EV market price.
