By fuel alone, the 2026 EV vs gas contest is a rout: home charging costs about $5.40 per 100 miles against $14.90 for a 30-mpg gas car at September’s $4.48 gasoline — AAA pegs EV charging at 66 to 70% cheaper than fueling. But nobody owns a fuel bill; they own a car. And the same AAA 2026 study that measured the charging savings also found that an EV medium sedan costs $3,080 a year — 29.1% — more to own overall than its gas equivalent, because depreciation swamps everything. The honest answer to “is an EV cheaper?” is therefore not a slogan but a ledger, and this guide builds it line by line with 2026 numbers.
The Fuel Bill: Where EVs Crush Gas
Start with the input prices, because 2026 changed them both. Regular gasoline averaged $4.478 a gallon nationally in late September (EIA), up about $1.31 from a year earlier — a genuine spike, not noise. Home charging averages 18.0¢ per kWh (AAA’s 2026 figure). For a typical driver, 12,000 miles a year:
| Gas car, 30 MPG | EV, 30 kWh/100 mi | |
|---|---|---|
| Cost per 100 miles | $14.93 | $5.40 |
| Cost per year (12,000 mi) | ~$1,790 | ~$650 |
| Five years | ~$8,950 | ~$3,240 |
That’s a $5,700 five-year advantage for the EV — real money, and bigger than it was a year ago because gas spiked while electricity stayed flat. Drive more, or own a thirstier vehicle, and it widens: a 15-MPG truck burns about $3,580 of fuel a year at these prices.
The fine print: the $5.40 assumes home charging at residential rates. Public fast-charging costs meaningfully more per kWh — drivers who rely on DC stations capture only part of that advantage — and renters without a garage face the same problem. The EV fuel win is largest for homeowners who charge overnight.
Where It Reverses: Depreciation
Now the biggest line in ownership. Kelley Blue Book’s 2026 data has the average new vehicle retaining 44.7% of its value after five years, while the worst-depreciating EVs retain far less — a Tesla Model 3 keeps 35.0%, a Porsche Taycan 37.8%. On comparable stickers, that gap alone adds $4,000 to $6,000 of five-year loss for the EV.
This is what AAA’s 2026 total-cost finding is made of: the EV medium sedan’s $3,080-a-year (29.1%) ownership premium over its gas twin is driven primarily by roughly double the depreciation — a higher sticker price compounded by a lower retained percentage. And the one policy that used to offset it is gone: the $7,500 federal EV credit expired September 30, 2025, with no replacement as of late 2026. The sticker is now the sticker.
The Rest of the Ledger
Maintenance: EVs genuinely cost less to maintain — fewer fluids, no oil changes, less brake wear from regenerative braking — and federal fuel-economy data confirms the qualitative advantage. The size of the saving depends heavily on the specific cars and how long you keep them; treat “EVs save ~half on maintenance” as plausible, not gospel, and price your specific models.
Insurance: EVs run meaningfully more to insure — about 42% more on average at full coverage per Insurify’s quotes data ($3,159 vs $2,218 a year), narrowing to ~18% on newer models. See the full breakdown in our EV insurance guide — but get real quotes on both candidates, since the spread between insurers can exceed the EV premium itself.
Upfront price: with the credit gone, the EV’s price premium over a comparable gas vehicle is back to being whatever the window sticker says — and it varies by segment more than any other input here. This is the line to check first, because every other calculation scales from it.
The Five-Year Ledger on Two Realistic Cars
Modeled with our car cost calculator inputs — 12,000 miles a year, September 2026 energy prices, KBB 2026 resale rates, estimated insurance and maintenance (the assumptions are adjustable, and you should adjust them):
| Line | Gas car ($40,000) | EV ($46,000) |
|---|---|---|
| Depreciation (45% vs 35% resale) | $22,000 | $29,900 |
| Fuel / charging | $8,950 | $3,240 |
| Insurance (est.) | $9,500 | $10,450 |
| Maintenance + tires (est.) | $4,500 | $3,500 |
| Registration + fees | $1,500 | $1,500 |
| Five-year total | ~$46,450 | ~$48,590 |
The EV’s charging advantage ($5,700) covers most of its extra depreciation in this model, but not all — the gas car lands about $2,100 cheaper over five years ($35 a month), close enough to AAA’s direction that the honest summary is: at 2026 prices, the total costs are roughly comparable, and the decision rests on the specific models’ prices and resale figures, not on fuel.
Three things flip it decisively in either direction. A high-mileage driver (20,000+ miles a year) pushes the fuel savings past $9,000 and the EV wins. Choosing the worst-resale EV against the best-resale gas car widens the gap to $5,000-plus the other way. And buying the EV used — letting the first owner eat the depreciation cliff — is where the EV math turns genuinely dominant, because the running-cost advantage arrives without the resale penalty.
When Each Side Wins
The EV wins when: you charge at home overnight, you drive high mileage, you buy it 2–3 years old at the depreciation discount, or your state still offers incentives (check DSIRE — state and utility programs survived the federal expiration).
The gas car wins when: you can’t charge at home, you resell within five years, you’re comparing a high-resale gas model against a fast-depreciating EV, or the segment’s EV price premium is unusually large.
Both lose to: a hybrid, quietly, in the middle — no charging dependency, near-EV fuel economy in town, and Toyota-class resale. The Sienna in KBB’s 2026 top ten is the pattern, not the exception.
Bottom Line
In 2026 the EV-vs-gas question is no longer about the pump: at $4.48 gas and 18¢ home charging, the EV’s fuel advantage is about $1,140 a year and growing with every gas spike. It’s about what happens at resale — and there, a 35% EV resale figure against 45% average still hands the win to the gas car on most five-year ledgers, which is why AAA’s measured total shows the EV costing $3,080 more a year despite the charging savings. Run both of your actual candidates through the car cost of ownership calculator with their real resale numbers from the 2026 rankings — the ledger, not the ideology, decides it.
FAQ
Is charging an EV really cheaper than buying gas in 2026?
Yes, dramatically — about $5.40 per 100 miles charging at home versus $14.90 for a 30-MPG gas car at September 2026 prices ($4.478/gal regular per EIA, 18.0¢/kWh home average per AAA). That’s roughly $650 a year versus $1,790 at 12,000 miles. The advantage shrinks if you rely on public fast charging and disappears somewhat for renters without home charging access.
Why do EVs cost more to own if charging is so cheap?
Depreciation. EVs at the bottom of the resale table retain 35 to 38% of their value after five years versus a 44.7% industry average, and their stickers often run higher than gas equivalents — so the value they lose outruns the fuel they save. AAA’s 2026 study measured the result: an EV medium sedan cost $3,080 more per year to own than its gas twin, driven primarily by depreciation.
Do EVs save money on maintenance?
Generally yes — no oil changes, fewer fluids, and regenerative braking extends brake life, and federal data confirms the direction. The exact dollar saving varies by model and ownership length, so treat it as a few hundred dollars a year rather than a fixed number, and don’t let it carry the whole comparison; insurance can run higher on EVs and claw part of it back.
Is it still worth buying an EV with the federal tax credit gone?
For the right buyer, yes — but the math changed. Since the $7,500 credit expired September 30, 2025, the sticker carries the full premium, which makes resale performance and high mileage more decisive. The strongest 2026 EV play is a 2-to-3-year-old used EV at the depreciation discount with home charging; the weakest is a new, fast-depreciating model bought to resell quickly.
