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.

Build the comparison

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.

Which vehicle is cheaper to own?

EV Crossover™
Worked example before you calculate

The gas car still wins—even though the EV is cheaper to fuel

Close gas advantage

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.

Horizon5 years
Driving15,000 mi/yr
EV vs gas price$47k vs $36k
Federal credit$0 current
Gas car ahead by about $2,160

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.

EV TCO≈ $47,093
Gas TCO≈ $44,932
EV energy saved≈ $4,913
Break-even≈ 21.6k mi/yr

The hidden ownership layer

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.

Depreciation

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.

Charging mix

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.

Financing

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.

Advisor lens

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.

Mileage crossover

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.

Pressure-test the winner

Which assumption can flip the result first?

A strong decision should survive a reasonable change in the assumptions you cannot know perfectly today.

Test 01

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.

Test 02

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.

Test 03

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.

Scope and limits

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.
Five-year worked case

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.
