EV Breakeven Mileage: How Many Miles Before an Electric Car Pays for Itself
Fast Facts
- $7,995 — the real-world premium: 2026 Equinox EV LT1 ($36,795, KBB) versus the gas Equinox LT ($28,800, Edmunds), both before destination.
- 9.8¢ — the fuel saving per mile at October 2026 prices: $4.33/gal regular (AAA) against 18¢/kWh home charging with a 12% charging loss (our calculation).
- $552 — the yearly maintenance, repair, and tire saving of a compact electric SUV over its gas twin (AAA Your Driving Costs 2026).
- ~59,400 miles, about 4 years — our breakeven calculation at 15,000 miles a year. Drive 8,000 miles a year and it stretches past 6 years.
- Effectively never — if you mostly DC fast-charge at ~55¢/kWh, the fuel saving disappears entirely.
Short Answer
At October 2026 US prices, an electric SUV that costs about $8,000 more than its gas twin breaks even after roughly 60,000 miles — about four years at 15,000 miles a year. Drive less and it takes longer; charge mostly at public fast chargers and it may never happen. The single biggest lever is the purchase premium, not the fuel price.
Ask “do EVs save money?” and you will get a sermon. Ask “after how many miles?” and you get a number you can argue with. That second question is the honest one, because every part of the EV money story — fuel, maintenance, the price gap — scales with miles. This article works the breakeven math with current prices, shows the formula so you can check it, and gives you a calculator to run your own numbers. Along the way it flags the one thing the formula hides: depreciation.
The Formula That Actually Answers It
Breakeven mileage is one division problem. Take the price premium — what the EV costs over the gas car you would otherwise buy — and divide it by the saving per mile the EV earns back:
Breakeven miles = price premium ÷ (fuel saving per mile + maintenance saving per mile)
That is the whole machine. Fuel saving per mile is the gas cost per mile (price per gallon ÷ mpg) minus the electricity cost per mile (kWh per mile × your rate, plus charging losses). Maintenance saving per mile is the yearly saving divided by your yearly miles. Notice what the formula says: the premium is fixed, so everything that matters — your miles, your gas price, where you charge — enters through the saving per mile. Two people can buy the same two cars and get completely different answers. The cheapest EVs to own are usually the ones with the smallest premium to recover, not the ones with the flashiest efficiency number.
Worked Example: One EV, One Gas Car, October 2026 Prices
Let us run the formula on a real pair, the 2026 Chevrolet Equinox EV against the gas 2026 Equinox — same nameplate, closest thing to an apples-to-apples comparison in the US market. Every input is sourced; the arithmetic is ours.
| Line item | Figure | Source |
|---|---|---|
| Equinox EV LT1 MSRP | $36,795 | Kelley Blue Book (KBB’s fair purchase price is lower, at $34,200) |
| Gas Equinox LT MSRP | $28,800 | Edmunds (both prices exclude destination, so they compare cleanly) |
| Price premium | $7,995 | Our calculation |
| Regular gas, national average | $4.33/gal | AAA, 15 Oct 2026 — record highs for autumn |
| Gas Equinox economy | 27 mpg combined | Edmunds, same page (EPA 26 city / 29 highway) |
| Gas cost per mile | 16.0¢ | Our calculation: $4.33 ÷ 27 |
| Equinox EV efficiency | 108 MPGe combined | CarPro review, EPA figure; our conversion: 33.7 kWh per gallon-equivalent ÷ 108 = 31.2 kWh/100 mi |
| Home electricity rate | 18¢/kWh | AAA Your Driving Costs 2026 charging basis (same fact sheet); EIA’s July 2026 national residential average was 18.31¢ |
| EV energy cost per mile | 6.3¢ | Our calculation: 0.312 kWh/mi × 1.12 charging loss × $0.18 |
| Fuel saving per mile | 9.8¢ | Our calculation: 16.0¢ − 6.3¢ |
| Maintenance/repair/tire saving | $552/year | AAA Your Driving Costs 2026: compact SUV EV $1,402 vs gas $1,954 |
At 15,000 miles a year, the $552 maintenance saving is worth 3.7¢ a mile. Add the 9.8¢ fuel saving and the EV earns back 13.5¢ a mile. Divide the $7,995 premium by $0.135 and you get about 59,400 miles — roughly 4 years at that mileage. That is the honest answer for this pair, at these prices, with home charging.
Same Car, Different Driver: The Mileage Table
Here is the part most breakeven articles skip: your yearly mileage changes the answer twice. More miles means more saving per year (faster payback in years), but the fixed yearly maintenance saving spreads thinner per mile (slower payback in miles). Same Equinox pair, our calculation:
| Miles per year | Saving per mile | Breakeven miles | Breakeven years |
|---|---|---|---|
| 8,000 | 16.7¢ | ~47,900 | ~6.0 |
| 10,000 | 15.3¢ | ~52,200 | ~5.2 |
| 12,000 | 14.4¢ | ~55,600 | ~4.6 |
| 15,000 | 13.5¢ | ~59,400 | ~4.0 |
| 20,000 | 12.6¢ | ~63,700 | ~3.2 |
The counterintuitive bit: the high-mileage driver needs more miles to break even, but gets there in fewer years. Years are what your loan term and your patience actually measure, so years are the number to watch.
Run Your Own Numbers
The calculator below uses the exact formula from the worked example. The defaults are the Equinox example above — replace every one with your own figures. Defaults are examples only, not recommendations.
How the tool computes it. Gas cost per mile is the gas price divided by the gas car’s mpg. EV energy per mile is the kWh-per-100-miles figure divided by 100, multiplied by 1.12 to account for roughly 12% charging loss between the wall and the battery (established in our home-charging analysis), then multiplied by your electricity rate. The fuel saving per mile plus the yearly maintenance saving divided by yearly miles gives the total saving per mile; the premium divided by that is the breakeven mileage, and dividing by yearly miles gives the years. Zero or empty inputs fall back to the example defaults so the tool never divides by zero.
What the Formula Quietly Leaves Out
The breakeven formula is honest about running costs and silent about everything else. Before you treat the answer as the whole truth, account for what it ignores:
Depreciation. This is the big one. AAA’s 2026 fact sheet puts depreciation at $4,334 a year on average — the single largest ownership cost for any car — and its per-class tables show electric versions shedding thousands more per year than their gas equivalents (per secondary reporting of the full 2026 tables, the electric medium sedan’s extra depreciation alone exceeds its entire operating-cost disadvantage). A car can break even on fuel and maintenance and still lose on total cost if it loses value faster. Our five-year EV versus gas comparison covers the full-cost view.
Where you charge. The whole 9.8¢ fuel saving assumes home charging at 18¢/kWh. The national DC fast-charging average sits around 55¢/kWh — at that rate the Equinox EV’s energy costs about 19¢ a mile, more than the gas car’s 16¢. A driver who mostly fast-charges may never break even, premium or not. This is why home charging economics matter more than any efficiency rating.
Insurance and financing. EVs often cost more to insure, and a bigger purchase price means bigger finance charges. Neither appears in the formula. Get real quotes before you commit.
Tires. EVs wear tires faster — tires are the single biggest recurring EV maintenance cost at roughly 2.7¢ a mile versus 1.0¢ for petrol cars. AAA’s $552 maintenance figure already includes one tire replacement set, but aggressive drivers will land above it. See our EV tire cost and wear guide for the details.
The charger itself. A home charger plus installation runs $500 to $2,000. Add it to the premium if you need one — it is part of the price of going electric.
Who Should Not Count on a Breakeven
Run the formula with brutal inputs and it will tell you no. That is a feature, not a bug. Skip the breakeven dream if you drive under about 8,000 miles a year and the EV costs $10,000+ more than the gas alternative — the math stretches past a typical ownership period, as our low-mileage EV analysis shows in detail. The same applies if you cannot charge at home, or if the gas car you are comparing against is a 40+ mpg hybrid: hybrids halve the fuel saving per mile, which roughly doubles the breakeven distance.
And one more uncomfortable truth: if you keep cars only three years, compare the three-year numbers, not the five-year ones. Breakeven at year four is a loss at year three.
Frequently Asked Questions
Does charging mostly at public fast chargers change the breakeven?
Completely. At roughly 55¢/kWh, the example EV’s energy costs about 19¢ a mile versus 16¢ for the gas car — the fuel saving goes negative and only the maintenance saving remains, pushing breakeven past 1.2 million miles. Home charging is the entire foundation of the EV fuel-saving story.
What if gas prices fall back to $3 a gallon?
The fuel saving for the worked example shrinks from 9.8¢ to about 4.9¢ a mile (our calculation: $3 ÷ 27 mpg − 6.3¢ EV energy). At 15,000 miles a year, breakeven stretches from ~4 years to ~6.2 years. Gas price is the second-biggest lever after the purchase premium.
Should I include the home charger installation in the price premium?
Yes. If you need a Level 2 charger installed, add its full cost to the EV’s premium before dividing. A $1,200 installation on top of a $7,995 premium pushes our example’s breakeven from ~59,400 to ~68,300 miles (our calculation). If the house already has a 240V outlet in the garage, the addition is zero.
Does a used EV change the answer?
Usually in your favor. The first owner absorbed the steepest depreciation, so a 2–3-year-old EV often carries a small premium — or none — over a comparable new gas car. With little or no premium to recover, breakeven can be effectively day one on running costs. Battery health is the risk to check; see our used-EV guidance.
Why do different articles give different breakeven numbers?
Because the inputs differ, not because the math does. Gas price, yearly miles, home versus public charging, and whether maintenance is included all move the answer by years. Any breakeven claim that does not show its inputs is a guess wearing a lab coat. Run the calculator above with your own numbers and keep the result.
Does this math include insurance?
No. The formula covers fuel and maintenance only. EVs frequently cost more to insure, which works against the breakeven. Treat insurance as a separate line item with real quotes, the same way you should treat financing costs on the larger purchase price.
The Short Version
EV breakeven is one division: the purchase premium divided by the saving per mile. At October 2026 prices — record autumn gas, 18¢ home electricity — a compact electric SUV costing $8,000 more than its gas twin pays back in roughly 60,000 miles, or four years of average driving. High-mileage drivers get there in fewer years; low-mileage drivers may never get there at all; public-charging drivers should not bother with the math. And remember what the formula omits: depreciation can erase the whole saving, so run the full-cost comparison before you sign.
These are estimates from public data, not financial advice. Your insurance, taxes, and local electricity rates will move the numbers — confirm the big ones with your dealer and insurer before buying.
