“EVs are cheaper to run” and “EVs are too expensive” are both repeated constantly, and both are too simple to be useful. The honest answer to whether an EV beats a gas car on cost is: it depends on a handful of specific numbers — your mileage, your electricity rate, where you charge, and the two cars you’re comparing. This guide plugs real 2026 figures into the comparison so you can see exactly where electric wins, where it narrows, and how to find your own break-even.
## The two inputs that decide everythingEnergy cost per mile comes down to two things on each side. For a gas car: the price of gas and the car’s MPG. For an EV: the price of electricity and the car’s efficiency (kWh per mile). Everything else in the “EV vs gas” debate is secondary to these.
As of early 2026: regular gas averages around $2.90 per gallon; residential electricity averages roughly $0.14–$0.17 per kWh. A typical gas car does 25–30 MPG; a typical EV uses about 27–33 kWh per 100 miles (roughly 0.30 kWh/mile).
Cost per mile: the core comparison
Run those numbers and the gap is clear. A home-charged EV costs roughly $0.04–$0.05 per mile in energy. A comparable gas car costs roughly $0.10–$0.13 per mile. That’s about half — sometimes a third — the per-mile energy cost.
The big caveat is where you charge. Public DC fast charging runs $0.25–$0.45 per kWh, which can push an EV’s cost per mile up near $0.10 and narrow the gap with gas considerably. The EV cost advantage is really a home-charging advantage. If you can’t charge at home and rely on public fast charging, the math changes — that’s the single most important question to answer before assuming savings.
Over a typical 12,000-mile year, the per-mile gap works out to roughly $600 a year in energy savings for a home-charging EV driver — about $3,000 over five years on fuel alone. In states that combine cheap electricity with expensive gas (parts of the Northeast, West Coast, Washington state), the annual saving can exceed $1,000. In states where electricity is expensive and gas is cheap, the advantage shrinks but rarely vanishes for home chargers.
Fuel is the headline, but maintenance widens the EV lead. EVs have no oil changes, no spark plugs, no exhaust, no multi-speed transmission, and regenerative braking that extends brake life. Routine maintenance over five years runs consistently lower than a comparable gas car’s. EVs still need tires (often sooner, due to weight and instant torque), cabin filters, and fluids — but the scheduled-service bill is materially smaller.
Where gas still wins
To be fair to the comparison, gas cars hold advantages that don’t show up in per-mile fuel cost:
- Lower purchase price, typically, for comparable models — which feeds lower depreciation in dollar terms.
- No charging logistics — no home-charger install, no range planning on long trips.
- Cheaper insurance, often, since EV repair and replacement costs can run higher.
- Better for low-mileage drivers — if you barely drive, the fuel savings that justify an EV’s higher up-front cost never accumulate.
The EV cost case is strongest for high-mileage drivers who can charge at home. It’s weakest for low-mileage drivers who’d rely on public charging and face higher EV insurance.
Finding your break-even
Because the up-front cost difference is paid back gradually through fuel and maintenance savings, there’s a break-even point — the mileage and time at which the EV’s running-cost advantage overtakes its higher purchase price. For a home-charging high-mileage driver that point comes quickly; for a low-mileage public-charging driver it may never arrive within a typical ownership period.
The only way to find your break-even is to run your actual numbers. Our EV Savings Calculator takes your mileage, electricity rate, and the vehicles you’re weighing, and shows the real comparison for your situation.
Frequently asked questions
Is an EV cheaper than gas over 5 years?
On fuel and maintenance, usually yes for a home-charging driver — roughly $3,000 in fuel savings over five years plus lower maintenance. Whether that offsets a higher purchase price and insurance depends on your mileage and the specific cars.
How much cheaper is an EV per mile?
Home-charged, about half the energy cost of a comparable gas car — roughly $0.045/mile vs $0.11/mile at 2026 prices. Relying on public fast charging narrows that gap.
Do EVs save money if I can’t charge at home?
Much less. Public DC fast charging ($0.25–$0.45/kWh) can erode most of the per-mile advantage. Home charging is what makes the EV cost case work.
What about maintenance — are EVs really cheaper?
Yes, on scheduled maintenance: no oil changes, fewer moving parts, longer brake life. EVs still need tires (sometimes sooner) and fluids, but routine service costs less than a comparable gas car.
When does an EV break even vs gas?
It depends on mileage, charging, and the price gap. High-mileage home-charging drivers break even fast; low-mileage public-charging drivers may not within a typical ownership window. Run your own numbers.
