EV vs Gas: The Real 5-Year Cost of Ownership
The two costs that flip the math: fuel and maintenance
An EV's running-cost advantage comes from two places. First, electricity is cheaper per mile than gasoline. At a typical home rate near $0.16 per kWh and an efficiency around 3.5 miles per kWh, an EV costs roughly $0.046 per mile to fuel. A 30-mpg gas car at $3.50 a gallon costs about $0.117 per mile — more than double. Over 12,000 miles a year that is roughly $550 for the EV against $1,400 for gas, an $850 annual gap before you touch a wrench.
Second, EVs have far fewer moving parts: no oil changes, no timing belts, no exhaust system, and regenerative braking that makes brake pads last much longer. Maintenance studies consistently put EV upkeep at roughly half the per-mile cost of a gas car. To turn your own electricity rate, gas price, and mileage into a personalized answer, run the EV vs gas cost calculator.
Five-year total cost, side by side
Here is a representative comparison: a $42,000 EV versus a $32,000 gas car, both driven 12,000 miles a year for five years. The EV assumes a $3,750 tax credit, home charging at $0.16/kWh, and lower maintenance; the gas car assumes $3.50/gallon at 30 mpg. Depreciation and insurance are estimated at market averages.
| Cost category (5 years) | Electric car | Gas car |
|---|---|---|
| Purchase price | $42,000 | $32,000 |
| Federal/state incentive | -$3,750 | $0 |
| Fuel / electricity | ~$2,750 | ~$7,000 |
| Maintenance & repairs | ~$2,000 | ~$4,500 |
| Insurance | ~$7,500 | ~$6,800 |
| Estimated depreciation | ~$21,000 | ~$16,000 |
| Net 5-year cost | ~$31,500 | ~$28,300 |
In this middling scenario the gas car is about $3,200 cheaper over five years — the lower purchase price and slower depreciation still outweigh the fuel savings at 12,000 miles a year. But the result is highly sensitive: raise the mileage, raise the gas price, or lower the EV's price and the EV wins outright.
What tips the balance toward the EV
The EV's case gets stronger fast under a few conditions. High mileage: at 20,000 miles a year the fuel and maintenance gap roughly doubles, often flipping the total in the EV's favor within three years. Cheap home charging: off-peak or solar charging can cut the per-mile fuel cost below $0.03. Expensive gas: in high-cost states, the gas car's per-mile fuel bill can be 3x the EV's. A full tax credit: a $7,500 credit versus a partial one changes the purchase-price gap dramatically. Because these swing the answer so hard, the right move is to model your own inputs rather than trust any single headline number — the true cost of ownership calculator lets you layer all of them together.
The hidden variables people forget
Two factors distort many comparisons. The first is public fast charging: it can cost $0.40 to $0.60 per kWh, several times a home rate, so a driver without home charging loses much of the fuel advantage. The second is depreciation, which for EVs has historically been steeper and more volatile as battery technology and incentives shift, though this varies enormously by model. Insurance also tends to run slightly higher on EVs because of costlier battery repairs. None of these are dealbreakers, but leaving them out of the math produces an EV number that is too rosy — always include charging access and resale in your estimate.
How to run the comparison for your own situation
Because the answer swings so hard on a handful of inputs, the only comparison that matters is the one built from your numbers, not a national average. Start by pulling four figures you actually control or can look up: your home electricity rate per kilowatt-hour from a recent bill, your local gas price, your real annual mileage from the odometer over the past year, and the specific tax credit the model you want qualifies for. Those four inputs move the result more than anything else on the spec sheet.
Next, be honest about charging. If you can charge at home overnight, the EV keeps its full fuel advantage; if you would rely on public fast chargers, cut that advantage sharply and re-run the math. Then estimate how long you will keep the car, because depreciation — the largest single cost for both vehicles — is only realized when you sell, and a longer hold spreads the EV's up-front premium across more years of fuel savings. Finally, do not forget insurance: get a real quote for both specific cars rather than assuming they cost the same, since EV battery repairs can push premiums higher. Feed all of this into the calculators below and you will get a total-cost answer tailored to how you actually drive, which is the only number worth acting on. A driver doing 25,000 miles a year with cheap home power and a full credit will often find the EV wins outright, while a low-mileage buyer without home charging may find gas stays cheaper for the whole five years.
Frequently asked questions
How many miles until an EV pays off versus gas?
The break-even mileage varies by your electricity price, gas price, and the purchase-price gap, but for a typical $8,000 to $10,000 price premium it usually falls between 60,000 and 100,000 total miles. Drivers who cover 20,000 miles a year with cheap home charging can hit break-even in two to three years, while low-mileage drivers may never fully close the up-front gap.
Is EV maintenance really cheaper than gas?
Yes, consistently. EVs skip oil changes, spark plugs, timing belts, exhaust systems, and most transmission service, and regenerative braking extends brake life. Independent cost studies put EV maintenance at roughly half the per-mile cost of an equivalent gas car. The main exception is tires, which can wear faster on heavier, higher-torque EVs.
Does the federal EV tax credit change the comparison a lot?
Substantially. A full $7,500 credit erases most of the typical purchase-price premium, often making the EV cheaper from year one. A partial credit or no credit leaves a larger gap that fuel savings must slowly recover. Because eligibility depends on the model, buyer income, and where the car is assembled, confirm the exact credit you qualify for before running the numbers.
What if I cannot charge at home?
Charging at home is where most of an EV's fuel savings come from. If you rely on public fast charging at $0.40 to $0.60 per kWh, your per-mile fuel cost can approach or exceed a gas car's, wiping out much of the advantage. Without reliable home or cheap workplace charging, the financial case for an EV weakens considerably.
Do EVs depreciate faster than gas cars?
Historically many EVs depreciated faster and less predictably than gas cars, partly because incentives on new models undercut used prices and battery technology moved quickly. This varies enormously by brand and model, and some EVs now hold value well. Since depreciation is often the single largest ownership cost, use a realistic resale estimate for the specific model you are considering.
Does electricity price matter more than gas price?
Both matter, but the ratio between them drives the result. A cheap-electricity, expensive-gas region maximizes the EV's edge, while cheap gas and pricey electricity can neutralize it. Enter your actual home rate per kWh and local gas price rather than national averages — regional variation is large enough to change which car is cheaper.
