⚡ EV Total Cost of Ownership Calculator
The sticker price lies. Add fuel, maintenance, insurance and resale over the years you actually keep the car.

⛽ Your driving & prices
Includes purchase price, energy/fuel, maintenance, insurance, minus estimated resale value. Excludes financing interest and incentives — both usually favor the EV further. Maintenance and resale are estimates; adjust them to match your situation.
What "EV Total Cost of Ownership" Actually Means
When people compare an EV to a gas car, they usually compare sticker prices — and the gas car wins. That's the wrong comparison. The EV total cost of ownership is everything you spend from the day you buy to the day you sell: the purchase price, every gallon or kilowatt-hour, every oil change and brake job, every insurance payment, minus whatever the car is worth when you sell it.
Nobody buys a car to look at the window sticker for eight years. You buy it to drive it. This calculator adds up the parts that actually hit your wallet, so you can see which car is genuinely cheaper for your mileage, your electricity rate, and your ownership period.
Where EVs Win (and Where They Honestly Don't)
Let's be straight about the scoreboard, because EV fans oversell this and skeptics undersell it.
Energy is the EV's biggest win. Driving 12,000 miles a year costs roughly $600–700 in electricity versus $1,400+ in gasoline. That's not a rounding error — it's the single largest running-cost gap, and it grows every year you own the car. Cross-check your own numbers with the EPA's fuel-economy data at fueleconomy.gov.
Maintenance is the second win. No oil changes, no spark plugs, no transmission service, far less brake wear thanks to regenerative braking. Real-world data consistently shows EVs costing 30–50% less to maintain. The calculator defaults to $400/year for the EV versus $800 for gas, which matches published averages — adjust if your situation differs.
Where the EV loses: purchase price and resale. EVs still cost more upfront — typically $5,000–$10,000 more than a comparable gas car. And here's the part EV enthusiasts skip: used EVs have historically depreciated faster than gas cars, partly because battery tech keeps improving (last year's range looks dated) and partly because buyers worry about battery health. The gap is narrowing as the used-EV market matures, but go in with open eyes: the calculator defaults to 35% residual for the EV versus 40% for gas.
Insurance is roughly a wash, slightly worse for EVs. Higher purchase prices and expensive battery repairs nudge EV premiums up. The difference is usually a few hundred dollars a year, not thousands.
A Worked Example: 8 Years, 12,000 Miles a Year
Using the calculator's defaults — a $42,000 EV at 3.3 mi/kWh versus a $32,000 gas car at 30 MPG, $3.50 gas, $0.17/kWh electricity:
- Energy/fuel: ~$620/year (EV) vs ~$1,400/year (gas)
- Maintenance: $400/year (EV) vs $800/year (gas)
- Insurance: $1,800/year (EV) vs $1,600/year (gas)
- Resale after 8 years: $14,700 back (EV) vs $12,800 back (gas)
- All-in total: the EV comes out roughly $8,000–$10,000 cheaper over 8 years
The pattern is consistent: the EV starts $10,000 behind on day one and claws it back at roughly $1,200–$1,500 a year. The break-even point usually lands around year 5–7. Drive more miles per year, and it arrives sooner. Drive very little, and the gas car can stay ahead the whole time — which is exactly why the calculator lets you enter your mileage.
What This Calculator Leaves Out (On Purpose)
No calculator covers everything, and I'd rather tell you what's missing than pretend it's complete:
Financing. If you're taking a loan, interest on a pricier EV adds up. Rough rule: every $10,000 borrowed at 7% over 5 years costs about $1,880 in interest.
Incentives. Federal, state, and utility incentives for EVs (and home charger installation) all improve the EV's case. They're deliberately excluded because they change by location and year — check what's available where you live and mentally subtract it from the EV's total.
Battery replacement. For most owners this never happens within 8 years — EV batteries typically carry 8-year/100,000-mile warranties against excessive degradation. If you plan to keep the car 12+ years, budget for it separately.
Your time. Home charging saves gas-station trips; road trips add charging stops. Worth something, hard to put a number on.
Frequently Asked Questions
Is the EV total cost of ownership really lower than a gas car?
Usually yes, over a typical 6–10 year ownership — the fuel and maintenance savings outweigh the higher purchase price. But it's not automatic: low-mileage drivers, very cheap gas, or very expensive electricity can flip the result. Run your own numbers above.
Why do EVs depreciate faster?
Mostly technology churn — each model year brings more range for less money, which pushes down used values — plus buyer anxiety about battery health. As batteries prove their longevity and the used market deepens, this gap is shrinking.
Does this work for electric bikes, vans, or buses too?
The math is the same, but the defaults are car-sized. For an e-bike, energy costs are nearly zero (pennies per charge) and the whole comparison becomes about purchase price versus a car or transit pass. For vans and buses, multiply the mileage — fleet operators see the fastest payback because fuel savings scale with miles driven.
Should I include the home charger installation cost?
Yes, for completeness — typically $500–$2,000 installed. Mentally add it to the EV's year-one total. Even then, it rarely changes the verdict over a multi-year ownership.
