Database / Guides / EV vs gas: the five-year fuel math

The sticker price is the distraction. Over five years, fuel is where EVs quietly win — here's the math from the EPA's own figures, averaged across every EV in our database.

The headline numbers

The EPA estimates fuel costs assuming 15,000 miles a year. Across the 91 EVs in this database, the average annual fuel cost is $784 — versus $2,855 for the average hybrid, which is already the thriftiest kind of gas car. Against a typical new gasoline vehicle, the average EV here saves $8,082 in fuel over five years. That's the EPA's comparison, not ours.

Cheapest miles in America

The single cheapest EV to fuel in our database is the 2025 Lucid Air: $500 a year in electricity. That's roughly $42 a month — less than one tank of gas for most drivers.

Why the gap is this big

Two reasons. Electricity is simply cheaper per mile than gasoline — about 3–4 cents a mile for an efficient EV versus 13–16 cents for a gas car at current prices. And EVs waste far less of it: an electric motor turns ~90% of its energy into motion, while a gas engine throws away two-thirds as heat. Efficiency compounds the price advantage.

The honest caveats

The EPA's figures use national-average electricity and gas prices — yours will differ. Expensive California electricity or cheap Texas gas narrows the gap; cheap overnight charging rates widen it. Fast public charging costs more per kWh than home charging. And fuel is only one cost: insurance, tires, and depreciation matter too. But on fuel alone, the math isn't close.

Questions, answered

How much does the average EV save on fuel over five years?

It varies by model, but the EPA's five-year savings figure — versus a typical new gasoline vehicle — averages several thousand dollars across the EVs in our database. See the guide for the exact average.

Are EPA fuel cost estimates accurate?

They're standardized, which makes them fair for comparison. They assume 15,000 miles a year at national-average energy prices — your electricity and gas rates will shift the numbers. Our fuel-cost calculator lets you plug in your own.

Do hybrids beat EVs on fuel cost?

No — the average EV in our database costs less per year to fuel than the average hybrid, which is already the thriftiest gas-powered option. Electricity is simply cheaper per mile.
