Cheapest EVs vs Gas: Total Cost Comparison 2026

The gas MINI costs $14,520 in 5-year depreciation vs $13,905 for the SE — essentially equal. The difference is running costs. You pay $533/year to charge the SE vs $1,371/year in gas for the hardtop. That $838/year gap compounds fast. The 114-mile range limits the SE to city driving, but within that use case, the math is unambiguous.

This comparison isn't close. The Bolt saves $885/year in fuel vs the Corolla, $500/year in maintenance (no oil changes), and carries almost identical depreciation despite costing $2K more at purchase. The Corolla is a benchmark efficient gas car — and the Bolt beats it by $6,376 over 5 years without any tax credit.

Same vehicle, different powertrain. The gas Equinox costs $1,846/year in fuel (26 MPG at $3.20/gallon) vs $706/year to charge the EV. The gas version also costs more to maintain and is slightly cheaper to buy — but fuel and maintenance savings close the $6,195 sticker gap in under 4 years. With the $7,500 federal tax credit, the EV wins before year 2.

The Sportage is $12,110 cheaper to buy. But 27 MPG at current gas prices costs $1,129/year more than charging the Niro EV, and Kia's lower EV maintenance adds another $500/year. Those annual savings erode the sticker gap over 5 years and put the Niro EV ahead by $3,351. No tax credit complicates the calculus for buyers sensitive to upfront cost.

The CX-5 is a well-regarded compact SUV with strong resale — yet the EV6 beats it by $2,435. The EV6 starts $11,400 higher and depreciates more in dollar terms, but $1,099/year in lower fuel and maintenance costs close that gap by year 5. Mazda's 28 MPG is good for a gas SUV. 3.9 mi/kWh is good for an EV. In this class, the EV has a structural operating cost advantage.

The Tucson is $11,250 cheaper upfront, and its lower purchase price keeps depreciation loss smaller. But $1,092/year less in fuel and maintenance for the Ioniq 5 adds up to $5,460 over 5 years — more than enough to cover that cost gap and still come out ahead by $2,210. With the $7,500 federal tax credit on the Ioniq 5, the EV wins by roughly $9,000.

The ID.4 is the least efficient EV on this list at 3.1 mi/kWh, which hurts its charging cost advantage. Yet it still beats the Tiguan by $2,140, largely because VW's maintenance costs are high on both — the EV just has fewer service items. The $7,500 tax credit on US-assembled ID.4 models swings this comparison to roughly $9,500 in the EV's favor.

The Sonata is a legitimate benchmark here — 33 MPG, reliable, and $11,665 cheaper to buy. The Ioniq 6's edge comes from 4.1 mi/kWh efficiency ($585/year to charge vs $1,455/year in gas) and lower maintenance. That $1,320/year operating cost gap is the only reason the EV wins despite starting $11,665 higher. Thin margin. With the $7,500 tax credit, it's not thin at all.

This is the tightest EV win on the list. The RAV4 is genuinely efficient at 28 MPG, and it holds value exceptionally well — Toyota's resale keeps depreciation low despite the lower sticker. The bZ4X costs $14,795 more to buy but saves $1,008/year in operating costs. At that rate, breakeven takes about 15 years — but 5-year TCO still lands in the EV's favor by $518. With the $7,500 tax credit, the bZ4X wins by about $4,000.
