The average used EV sold for $34,653 in March, according to Cox Automotive. The average used gas car: $33,551. The $1,102 gap is the narrowest it's ever been. A year ago that same premium was $3,923.
How the Gap Closed in 12 Months
Two things happened simultaneously. Used EV supply expanded fast as off-lease vehicles returned in volume: Cox Automotive projects EVs will represent 8% of all lease returns in 2026, up from 2% in 2025. Vehicles leased during the 2022 and 2023 EV incentive wave are hitting the market now, all at once. Used EV prices fell 6.1% year over year through March.
Meanwhile, gas climbed. The national average hit $4.55 a gallon in early May, per AAA, up roughly 47% from the same period a year ago. Middle East supply disruptions ran longer than markets expected.
93,500 used EVs sold in Q1 2026, up 12% year over year per Cox Automotive. Buyers are running the numbers.
The 3-Year Cost Comparison
This table assumes 15,000 miles per year and home charging access for the EV buyer:
| Cost | Used gas car | Used EV | Basis |
|---|---|---|---|
| Purchase | $33,551 | $34,653 | Cox Automotive, March 2026 |
| 3-yr fuel | $8,531 | $2,250 | $4.55/gal at 24 MPG vs. $0.05/mi charging (DOE avg) |
| 3-yr insurance | $5,400 | $6,984 | EV runs ~$44/mo more per NAIC data |
| 3-yr maintenance | $3,600 | $1,500 | EVs skip oil changes and most fluid services |
| 3-yr total | $51,082 | $45,387 |
The EV runs about $5,700 cheaper over three years, even starting with a higher purchase price. Fuel does most of the work: $8,531 in gas versus $2,250 in electricity. Insurance goes the other way, adding roughly $1,584 more over three years on the EV side.
Three costs the table doesn't capture can change the outcome.
The Risks That Aren't in the Numbers
Battery replacement. A Model 3 battery pack replacement runs $10,000 to $16,000 depending on year and configuration. Most used EVs won't need one: batteries have held up better than early estimates predicted. But the cost exists and isn't reflected in ownership averages. Before signing, get a Recurrent battery health report. Many listings include one; request it if yours doesn't.
Charging access. The $0.05/mile figure assumes a home charger. DC fast charging at public stations runs $0.25 to $0.35 per mile on major networks. If that's your primary charging method, the fuel savings disappear entirely and the gas car wins on operating cost.
Collision repairs. EV repairs average about 25% more than equivalent gas car repairs, per RepairSmith data, largely due to battery and structural complexity. This is already baked into the insurance premium, but out-of-pocket exposure on an at-fault incident is meaningfully higher.
The Under-$25,000 Case
44% of used EVs sold for under $25,000 in Q1 2026, per Recurrent Auto. At that price the math shifts again: a 2020 Chevy Bolt at $22,000, a 2019 Nissan Leaf Plus at $21,000, or a 2021 Hyundai Kona Electric often costs less than a comparable-age Civic or Corolla in solid condition. Fuel savings layer on top of a lower purchase price rather than offsetting a premium.
The under-$25,000 segment carries a specific risk: older battery chemistry. 2018 to 2021 Nissan Leafs in particular show meaningful range loss by year five or six. Check range remaining, not just mileage.
No Federal Credit Anymore
The used EV federal tax credit, which covered up to $4,000 on qualifying vehicles priced under $25,000, expired September 30, 2025 under the One Big Beautiful Bill Act. There's no federal credit for used EV purchases in 2026. Some states still offer their own programs; check your state energy office for what's currently available, since programs vary widely.
Who This Works For
The used EV TCO case is strongest if you own your home or have reliable workplace charging, drive 12,000 or more miles per year, plan to keep the car at least four years, and choose a model with an established track record. The Model 3, Model Y, Chevy Bolt, and Hyundai Ioniq 6 have enough real-world data now to assess battery trends, repair frequency, and resale trajectories with confidence.
The gas car still wins if you rent without dedicated charging, drive under 10,000 miles annually, or need the predictability of a lower purchase price and a more established repair ecosystem.
How does the total cost of owning a used EV compare to a used gas car in 2026?
Over three years at 15,000 miles per year, a used EV runs about $5,700 cheaper to own than a comparable gas car, even starting with a $1,102 higher purchase price. Fuel savings drive the gap: $8,531 in gas costs versus $2,250 in electricity at home-charging rates. Higher EV insurance (about $44/month more per NAIC) partially offsets it.
Is $4.55 gas making used EVs a better deal than they were a year ago?
Significantly. A year ago the used EV price premium over a gas car averaged $3,923. Now it's $1,102, per Cox Automotive March 2026 data. At $4.55/gallon, that $1,102 purchase premium washes out in under a year of fuel savings for drivers doing 15,000 miles annually with home charging.
What's the biggest risk when buying a used EV in 2026?
Battery replacement cost. A full pack replacement on a 2019 to 2022 EV runs $10,000 to $16,000. Most used EVs don't need one, but it's the tail risk that can erase years of fuel savings in a single repair bill. Request a Recurrent battery health report before committing.
