The honest answer to "is an electric car cheaper?" is: it depends on four numbers, and most comparisons only show you one of them. Fuel cost is where EVs win decisively. Maintenance is a solid second win. Insurance is a consistent loss. And purchase price and depreciation are where the whole thing is decided.
This is the full comparison, line by line, with 2026 figures. No assumed tax credits — those ended for vehicles acquired after September 30, 2025 — and no hand-waving about "typical savings". At the end there is a break-even framework you can run against your own mileage and electricity rate.
1. Fuel: The EV's Biggest Win
This is the line item that carries the entire argument, and it is not close when you charge at home.
At the 2026 US national average residential electricity rate of 17.65 cents per kWh (EIA data), a typical EV doing about 3.5 miles per kWh costs roughly 5.0 cents per mile. A comparable 28 mpg gas car at $3.86 per gallon costs about 13.8 cents per mile. Over 12,000 miles a year, that is roughly $600 for the EV against roughly $1,656 for the gas car — a saving of about $1,050 annually, which matches AAA's finding that EV owners pay around $1,000 a year less for fuel.
But the spread across states is enormous, and it is the variable most likely to change your personal answer:
| Scenario | Rate | Cost per mile | 12,000 mi / year |
|---|---|---|---|
| Home, off-peak TOU | ~$0.10 / kWh | ~$0.029 | ~$343 |
| Home, Idaho average | $0.126 / kWh | ~$0.036 | ~$432 |
| Home, US average | $0.1765 / kWh | ~$0.050 | ~$605 |
| Home, California average | ~$0.33 / kWh | ~$0.094 | ~$1,131 |
| Public DC fast charging | $0.35 – $0.60 / kWh | ~$0.10 – $0.17 | ~$1,200 – $2,057 |
| Gas car, 28 mpg | $3.86 / gal | ~$0.138 | ~$1,656 |
Assumes 3.5 miles per kWh. Efficiency drops in cold weather and at sustained highway speeds.
The pattern is worth stating plainly: a home-charged EV in a cheap-electricity state is dramatically cheaper to fuel than any gas car. An EV charged exclusively on public fast chargers is not cheaper than a gas car at all. Everything else in this comparison is a rounding error next to that distinction, which is why our home charging guide is the first thing to read before buying.
2. Maintenance: A Consistent, Modest Win
Electric drivetrains have far fewer moving parts. There is no oil to change, no spark plugs, no timing belt, no exhaust system, no fuel filter, and no transmission fluid in most designs. Regenerative braking does much of the slowing, so brake pads and rotors routinely last two to three times longer than on a gas car.
AAA's Your Driving Costs research puts EV maintenance at roughly $330 per year less than a comparable gas vehicle, with EVs averaging around $949 annually. Over five years, total maintenance for a mid-size EV typically runs near $1,500 against $4,000 to $4,500 for the gas equivalent — a saving in the region of $2,500 to $3,000 across the period.
Two caveats. Tyres wear faster on EVs, because they are heavier and deliver instant torque; budget for replacement 20 to 30 percent sooner. And cabin air filters, brake fluid, coolant for the battery thermal system, and suspension components all still need servicing on the normal schedule.
3. Insurance: The EV's Consistent Loss
Insurers price policies on what it costs to repair the car, and EVs are more expensive to repair. Battery packs are costly, structural damage near the pack often requires specialist procedures or write-off, and the certified repair network is thinner than for gas cars.
The result is a premium gap of roughly $200 to $600 per year, with Consumer Reports data putting the average around $230. That gap widened slightly across 2025 and 2026. It is not enough to overturn the fuel savings, but it is enough to matter on a five-year comparison — roughly $1,000 to $3,000 over the period.
Get quotes before you sign
The insurance gap varies enormously between models, not just between EVs and gas cars. Two similarly priced EVs can differ by several hundred dollars a year depending on repair costs and claims history. This is invisible until you actually request a quote, so do it during the test-drive stage rather than after the purchase agreement.
4. Purchase Price and Depreciation
This is where the comparison is decided, and where the end of federal incentives changed the picture. Before October 2025, a $7,500 credit made many EVs cheaper than their gas equivalents on day one. Without it, most EVs carry a purchase premium of roughly $3,000 to $8,000 against a comparable gas model — though in the budget segment that gap has narrowed sharply, with cars like the $29,990 Nissan Leaf priced close to conventional rivals.
Depreciation is the wildcard, and it cuts both ways. EVs depreciated heavily between 2021 and 2024 as new models improved rapidly and prices fell, which hurt early owners badly. That is excellent news if you are buying used and poor news if you are buying new and plan to sell in three years. The market has stabilised somewhat as the technology has matured, but EV residual values remain harder to predict than gas-car values, so build in a margin of caution if you are a frequent trader rather than a long-term keeper.
One partial offset: a federal deduction allows up to $10,000 per year of interest on a qualifying new car loan for a US-assembled vehicle, running through 2028, phasing out above $100,000 of income for single filers and $200,000 for joint filers. It is a deduction rather than a credit, so its real value is a fraction of the old $7,500 — but it is worth raising with your tax preparer.
5. The Five-Year Picture
Putting it together for a driver covering 12,000 miles a year with home charging at the US average electricity rate:
| Cost over 5 years | Electric | Gas (28 mpg) | Difference |
|---|---|---|---|
| Fuel / electricity | ~$3,000 | ~$8,280 | EV saves ~$5,280 |
| Maintenance | ~$1,500 | ~$4,250 | EV saves ~$2,750 |
| Insurance premium gap | +$1,150 | — | Gas saves ~$1,150 |
| Home charger install | ~$1,700 once | — | Gas saves ~$1,700 |
| Purchase premium | +$3,000 – $8,000 | — | Gas saves $3,000 – $8,000 |
| Net position | EV ahead by roughly $180 to $5,180 over five years | ||
Illustrative figures for a US driver at 12,000 miles per year, home charging at $0.1765/kWh, gas at $3.86/gal. Excludes depreciation, which varies by model. Your result will differ.
The honest reading of that table is that the EV wins, but the size of the win depends almost entirely on which end of the purchase-premium range you land on. Buy a budget EV priced close to its gas equivalent and you are ahead within two years. Pay an $8,000 premium and drive modestly and you may be roughly even at the five-year mark.
6. Working Out Your Own Break-Even
Rather than trusting any generic figure, run these four steps with your own numbers.
Step 1: Find your fuel saving per mile. Take your electricity rate, divide by your candidate EV's efficiency in miles per kWh (3 to 4 is typical), and you have your EV cost per mile. Then divide your local gas price by your current car's real mpg. The difference between the two, multiplied by your annual mileage, is your yearly fuel saving.
Step 2: Add $330 for maintenance. This is AAA's average annual difference and is a reasonable planning figure.
Step 3: Subtract your insurance gap. Use real quotes, not an average. Typically $200 to $600.
Step 4: Divide. Take the purchase premium plus your charger installation cost, and divide it by the annual net saving from steps 1 to 3. That is your break-even in years. If it is under the number of years you plan to keep the car, the EV is cheaper for you.
The three conditions that decide it
An EV is almost certainly cheaper for you if all three are true: you can charge at home, you drive more than about 12,000 miles a year, and you keep cars for five years or more. If none of those are true, a fuel-efficient gas or hybrid car will very likely cost you less. Most people fall in between, which is why running your own numbers beats any generic verdict.
7. Costs Both Sides of the Argument Forget
Tyres. Heavier cars and instant torque mean EV tyres wear faster, and EV-specific tyres cost more. Add roughly $100 to $200 a year against the EV.
Cold weather. Winter range losses of 20 to 30 percent mean 20 to 30 percent more kWh purchased for the same miles during cold months. If you live somewhere with real winters, adjust your fuel saving down accordingly — a heat pump reduces but does not eliminate this.
Road-trip charging. Even a home charger owner uses public fast charging on long trips, at two to three times the home rate. If 15 percent of your miles are road trips, your blended fuel cost is meaningfully higher than the home-charging figure.
Registration fees. Many states now levy an annual EV surcharge, typically $50 to $250, to replace lost fuel tax revenue. Check yours; it comes straight off the saving.
On the gas side: oil changes, emissions testing, transmission service, exhaust repairs, and fuel price volatility. The $3.86 per gallon in this analysis is a snapshot, and gas prices have historically moved far more than electricity rates.
Frequently Asked Questions
Is an electric car cheaper than a gas car in 2026?
For most drivers who can charge at home, yes — but the margin narrowed when the $7,500 federal credit ended in September 2025. A typical owner saves roughly $1,000 a year on fuel and about $330 a year on maintenance, offset by $200 to $600 a year in higher insurance, for a net operating saving of around $800 to $1,100 annually. Whether that beats a higher purchase price depends on your mileage, your electricity rate, and how long you keep the car.
How much does it cost per mile to drive an electric car?
At the 2026 US average electricity rate of about 17.65 cents per kWh, home charging costs roughly 4 to 5 cents per mile. A comparable 28 mpg gas car at $3.86 per gallon costs about 12 to 14 cents per mile — roughly three times more. Public DC fast charging at $0.35 to $0.60 per kWh raises the EV figure to roughly 10 to 17 cents per mile, which largely erases the advantage.
Why is EV insurance more expensive?
Insurers price on repair cost, and EVs are more expensive to repair. Battery packs are costly to replace, structural repairs near the pack often require specialist procedures, and the network of certified repair shops is smaller. The typical gap is $200 to $600 per year, with Consumer Reports data putting the average at around $230. The gap widened slightly in 2025 and 2026, so get quotes on the specific model before you buy.
At what mileage does an EV become cheaper than a gas car?
The break-even point moves with your driving. At 12,000 miles a year with home charging, most owners recover a $4,000 to $6,000 price premium in roughly four to five years. Drive 20,000 miles a year and it can happen in under three. Drive 5,000 miles a year and it may never happen, because fuel savings scale with distance while the purchase premium and insurance gap do not.
The Bottom Line
For a driver who charges at home, covers 12,000 or more miles a year, and keeps a car for five years, an electric car in 2026 is still clearly the cheaper option — on the order of $1,300 to $1,500 a year in operating savings before accounting for the purchase premium. Fuel is where the win comes from, maintenance adds a solid second layer, and higher insurance takes a predictable bite out of both.
What has changed is that the case no longer makes itself. With the federal credits gone, the purchase premium is real money that you have to earn back through use, which means low-mileage drivers and anyone without home charging should run the numbers carefully rather than assume. The four-step break-even calculation above takes about ten minutes and is worth far more than any average.
