EV Cost Comparison Calculator USA
Compare the full ownership cost of an EV and a gas car over the years you actually expect to keep them. See which option wins, how much the gap is worth per month, and the annual mileage where the economics can flip.
Method, current data anchors and model limits
How the ownership model is built
EV ownership cost = depreciation + financing interest paid during the ownership period + charging + maintenance + insurance + optional charger/setup cost − verified incentives.
Gas ownership cost = depreciation + financing interest paid during the ownership period + fuel + maintenance + insurance.
Depreciation is purchase price minus the resale value you enter. Loan principal repayment is not counted twice: principal buys the vehicle, while depreciation measures the part of that asset value consumed during ownership.
EV Crossover™ solves for annual miles where the gas fuel cost per mile minus EV charging cost per mile offsets the remaining fixed ownership gap. Annual maintenance and insurance remain fixed annual assumptions rather than being converted into fake per-mile costs.
Model version: EV-TCO-US 6.0 • Source review: 2026-08-12.
Included: vehicle price, financing, depreciation, energy/fuel, maintenance, insurance, verified incentives and optional EV setup cost. Excluded unless already inside your purchase-price or annual-cost inputs: sales tax, registration, parking, tolls, repairs from accidents, battery replacement outside your chosen maintenance allowance and the time value of money.
The example defaults are planning inputs, not claims about the price, APR, insurance or resale value of a typical U.S. vehicle. Replace them with quotes for the two vehicles you are actually considering.
Official references used for this model
Current federal-credit note: the IRS states that the New Clean Vehicle, Previously-Owned Clean Vehicle and Qualified Commercial Clean Vehicle credits are not available for vehicles acquired after September 30, 2025. The legacy federal-credit input therefore defaults to $0 and should only be used for an eligible earlier acquisition.
Start with the numbers that can actually change the winner
Use the two vehicles you would genuinely buy. Core driving and energy assumptions stay visible; financing, insurance, resale and legacy incentives sit inside Advanced assumptions so the first screen stays readable without hiding the factors that matter.

Before you trust the result
Which vehicle is cheaper to own?
The gas car still wins—even though the EV is cheaper to fuel
Using the example inputs on the left and a $0 current federal credit, the EV saves on energy and maintenance but does not fully overcome the larger depreciation, financing and insurance burden over five years.
The gap is roughly $36 per ownership month. The EV needs about 21,600 miles per year under these assumptions before lower energy cost closes the fixed ownership gap.
Example only — enter your numbers for a personal estimate. Example prices, APR, insurance, maintenance and resale are planning assumptions; electricity and gasoline rate seeds reflect the source review noted above.
The result will compare all-in ownership cost and explain whether the margin is strong or fragile.
The memorable number is the difference after all modeled ownership costs.

Where the EV saves money—and where it gives those savings back
The table reconciles the same calculation used by the Smart Result, crossover visual, charts and Excel export. Amounts are economic ownership costs over your selected horizon.

See which cost driver matters now—and which one matters if your mileage changes
The first chart explains the final ownership structure. The second changes only annual mileage so you can see whether the winner is robust or sitting close to the crossover.
Five ownership buckets: EV vs gas
Depreciation, financing, energy/fuel, maintenance and insurance/setup effects over the same horizon.
Ownership gap as annual mileage changes
Positive values mean the EV is cheaper. Negative values mean the gas car is cheaper.
Keep the comparison with the assumptions attached
The Excel report includes the verdict, both ownership totals, every input, the forensic breakdown and source-review metadata so the number is not separated from the assumptions that produced it.
Why cheaper charging does not automatically make the EV cheaper to own
Fuel or electricity is only the part of the cost that moves with every mile. The larger ownership decision often sits in depreciation, financing and insurance.
Resale can erase years of charging savings
If the EV loses several thousand dollars more value than the gas car over the same period, energy savings have to recover that gap before the EV is financially ahead.
Home charging and public charging are different economics
A driver with dependable home charging can have a very different cost per mile from someone who regularly depends on DC fast charging.
The price premium also carries interest
A higher purchase price can create a second cost through loan interest. The model calculates interest actually paid during the ownership period instead of treating every payment as interest-free principal.
The right question is not “Are EVs cheaper?”
Ask whether this EV, at your charging mix, against the gas vehicle you would actually buy, is cheaper over the years you expect to keep it. A national average cannot make that decision for you.
How much driving is enough to overcome the fixed EV ownership gap?
The crossover calculation separates fixed horizon costs from variable energy cost per mile. That makes the threshold easier to interpret and prevents annual maintenance allowances from being incorrectly turned into mileage-dependent costs.
Suppose the EV costs more after depreciation, financing and insurance, but saves about six or seven cents on every mile of energy. At low annual mileage, those cents accumulate too slowly. At higher mileage, the energy advantage can eventually recover the fixed gap. EV Crossover™ solves that threshold directly.
A threshold below your normal driving level strengthens the EV case. A threshold far above your actual mileage is a warning that the EV win depends on something else—such as a large verified incentive or an optimistic resale assumption. If there is no mileage-only crossover, the tool says so rather than inventing one.
Which assumption can flip the result first?
A strong decision should survive a reasonable change in the assumptions you cannot know perfectly today.
Lower the EV resale value by 5 points
If a small resale change reverses the winner, the result is depreciation-sensitive. That is not a reason to reject the EV; it is a reason to price the uncertainty before signing.
Add 20 percentage points of public charging
This catches the common case where home charging is expected but apartment living, travel or convenience pushes more sessions onto paid public networks.
Reduce annual mileage by 20%
Lower driving weakens the part of the EV advantage that scales with use. If the EV still wins, the decision is less dependent on an aggressive mileage assumption.
What belongs inside this comparison—and what should stay outside it
Total cost is only useful when the same treatment is applied to both vehicles and uncertain assumptions are visible.
- Use comparable purchase prices. If one price includes sales tax and dealer fees, the other should too.
- Use insurance quotes with comparable coverage. A cheap quote with a different deductible is not a fair EV-vs-gas comparison.
- Treat charger installation as optional setup cost. Enter it when the EV purchase requires new home equipment; leave it at $0 when you already have charging or do not need installation.
- Do not treat a legacy federal credit as current cash. For acquisitions after September 30, 2025, the federal clean-vehicle credits referenced by the IRS are unavailable; the field defaults to $0.
- Do not force environmental value into the dollar verdict. Emissions, performance, convenience and charging access can matter personally, but this page keeps the headline decision focused on modeled ownership cost.
A driver can save thousands on energy and still spend more on the EV
The worked example is intentionally not an EV victory. It shows why the page exists.
With the default comparison, the EV costs $47,000 and the gas alternative costs $36,000. The driver covers 15,000 miles a year for five years, pays the reviewed electricity and gasoline reference rates shown in the inputs, and receives no current federal clean-vehicle credit. The EV uses less money for energy and maintenance, but the larger depreciation, higher financing interest and higher insurance assumption still leave the gas car ahead by roughly $2,160.
The important number is not the $4,900-or-so energy saving by itself. The important number is the ownership gap after every modeled category is reconciled. Under those inputs, annual mileage has to rise to roughly 21,600 miles before the energy advantage becomes large enough to offset the fixed EV cost gap.
Three checks that make the result decision-safe
Run these before treating a narrow calculator win as a purchase recommendation.
Replace both insurance examples
Get quotes for the exact trims. If insurance is the largest swing factor, use the Auto Insurance Cost Calculator USA to pressure-test the annual assumption.
Separate payment comfort from ownership cost
A longer term can make the monthly payment look easier while increasing interest. Use the Auto Loan Calculator USA if financing—not propulsion—is the main uncertainty.
Compare the ownership structure too
If the real choice is lease versus purchase, run the Lease vs Buy Calculator USA before treating two financed purchases as the only options.
EV vs gas ownership questions buyers actually ask
These answers explain the model boundaries and the assumptions most likely to change the decision.
No. Lower energy and routine maintenance cost can be outweighed by a higher purchase price, depreciation, financing, insurance, public charging or setup cost. The answer depends on the two vehicles and your ownership pattern.
Only when you are modeling an acquisition that was actually eligible under the earlier rules. The IRS states that the federal clean-vehicle credits are not available for vehicles acquired after September 30, 2025, so the current default is $0.
Because depreciation often represents one of the largest ownership-cost categories. A few percentage points of resale difference on a $40,000–$50,000 vehicle can be worth more than a year of charging savings.
It is the annual driving level where the variable energy saving per mile offsets the remaining fixed ownership-cost gap over your chosen horizon. It is not a guarantee because resale, insurance and future energy prices can change.
Include it when buying the EV requires new equipment or electrical work that you would not otherwise pay for. Leave it at $0 if you already have suitable charging or the cost does not belong to this vehicle decision.
Yes. Replace the purchase prices, APRs, maintenance, insurance and resale assumptions with values appropriate for the used vehicles. Do not assume an expired federal used-EV credit for a current 2026 acquisition.
