Gas vs Electric Car: Total Cost of Ownership
The sticker is only the first line. Over 8 years at 15,000 miles a year, a $35,000 gas car at 30 MPG and $4.27 a gallon burns $17,080 in fuel, while a $42,000 EV at 18.3¢/kWh uses $6,588 in electricity — and with maintenance at $1,000 vs $500 a year, the EV wins by $7,492 even with no tax credit. Change any input and the verdict recomputes. The federal $7,500 EV credit ended September 30, 2025 — so the calculator treats it as an input, defaulting to $0.
What the comparison shows
At the defaults — $35,000 gas car at 30 MPG vs $42,000 EV at 30 kWh/100mi, 15,000 miles a year for 8 years, $4.27/gal gas, 18.3¢/kWh home electricity, maintenance $1,000 vs $500 a year, $0 tax credit — the gas car costs $60,080 total ($35,000 purchase + $17,080 fuel + $8,000 maintenance) and the EV costs $52,588 total ($42,000 + $6,588 energy + $4,000 maintenance). The EV saves $7,492: $10,492 on fuel vs energy, minus a $7,000 purchase premium, plus $4,000 on maintenance.
| Output | Formula | What it means |
|---|---|---|
| Total cost: gas | price + (miles ÷ MPG × $/gal × years) + (maint × years) | Everything you spend on the gas car: $60,080 at the defaults. |
| Total cost: EV | price + (miles × kWh/100 × ¢/100 × years) + (maint × years) − credit | Everything you spend on the EV, minus any credit: $52,588 at the defaults. |
| The gap | gas total − EV total | Positive means the EV wins. Here: +$7,492 over 8 years — about $936 a year. |
| Fuel vs energy saved | gas fuel − EV energy | The engine of the EV’s win: $10,492 over 8 years ($2,135/yr vs $824/yr). |
| Maintenance saved | gas maint − EV maint | No oil changes, no exhaust: $4,000 over 8 years at the defaults. |
The honest wrinkle: this compares purchase + fuel/energy + maintenance only — not insurance, financing, or depreciation. AAA’s 2026 Your Driving Costs study found EVs average $12,704 a year in total ownership vs $9,910 for hybrids, because EVs carry the highest insurance costs of any vehicle type and depreciate faster. The fuel math favors the EV; the insurance bill fights back. See the full series on the X vs Y comparisons hub.
Who uses this
- The high-mileage commuter: driving 20,000+ miles a year makes the $2,135-vs-$824 annual fuel gap the whole story — they type their real mileage and watch the EV gap widen.
- The cheap-electricity homeowner: on a 12¢/kWh rate or overnight time-of-use plan, the EV’s energy line nearly halves — they rerun the math with their utility bill number.
- The skeptical spreadsheet driver: burned by old comparisons that subtracted a $7,500 credit — they set the credit to $0 and want the honest post-credit answer.
- The used-car shopper: they price a $25,000 used EV against a $22,000 used gas car and discover the fuel math can flip even a small price premium.
Accuracy & limitations
This is a purchase + fuel/energy + maintenance comparison — it does not model insurance (EVs cost more to insure, per AAA), financing interest, depreciation/resale (EVs have depreciated faster in 2026, narrowing the gap), registration surcharges (some states charge EVs up to $400 extra), battery replacement (rare, but a tail risk), or public-charging prices (typically far above home rates). Gas prices and electricity rates are entered as flat averages — real prices move. Treat this as the direction and scale of the answer; get insurance quotes and check your utility’s EV rate before buying.

Is an electric car cheaper than a gas car in 2026?
On fuel and maintenance alone, usually yes — our defaults show the EV saving $7,492 over 8 years ($2,135/yr fuel vs $824/yr energy, plus $4,000 less maintenance). But the full picture is tighter: AAA’s 2026 Your Driving Costs study found EVs average $12,704 a year in total ownership vs $9,910 for hybrids, because EVs carry the highest insurance costs and steeper depreciation. Run the calculator with your mileage and rates — then get insurance quotes before deciding.
Does the $7,500 EV tax credit still exist in 2026?
No. The federal $7,500 new-EV credit (and the $4,000 used-EV credit) ended for vehicles acquired after September 30, 2025 under the One Big Beautiful Bill Act — with only a narrow binding-contract transition rule for buyers who ordered before the cutoff. That’s why the calculator defaults the credit to $0. Some states (Colorado, New York, Massachusetts) and utilities still offer their own incentives — enter those in the credit field.
How many miles do I need to drive for an EV to pay off?
It depends on the price premium and your fuel gap — but at the defaults the EV saves about $936 a year, so it covers its $7,000 price premium in roughly 7–8 years at 15,000 miles a year. Drive 20,000+ miles a year and payback lands in year 5; drive 8,000 and it may never come. Type your real mileage in the calculator — that one input moves the answer more than any other.
Is home charging really that much cheaper than public charging?
Yes — dramatically. At the 18.3¢/kWh US average, 12,000 miles costs about $630 a year at home; public DC fast charging is typically priced well above residential rates and can erase most of the fuel savings. AAA reported public charging near 41¢/kWh in October 2026 — more than double the home rate. The calculator assumes home charging; if you’ll mostly use public chargers, type 35–45¢ and watch the gap shrink.
What about battery replacement costs?
Modern EV batteries are warrantied for 8 years / 100,000 miles (federal minimum), and outright replacement outside warranty can run $10,000–20,000 — the tail risk that scares buyers most. In practice, data shows most packs lose 10–15% of capacity over a decade rather than dying outright. The calculator doesn’t model replacement; if you plan to keep the car past the warranty, mentally add a risk premium to the EV side.
Should I buy a hybrid instead?
Maybe — hybrids are the quiet winners of 2026. AAA found hybrids had the lowest average yearly operating cost of any category studied (~$9,910/year), and hybrid sales ran above 216,000 a month all summer. A hybrid splits the difference: no charging needed, much of the fuel saving. Price one against both doors in the calculator by entering its price and MPG as the “EV” with electricity at $0.
