Vehicle EconomicsEV Price Premium Break-Even
What is the most an EV should cost for its charging savings to actually pay off?
Why this comes up
EV vs Gas Break-Even Mileage solves the mileage threshold. This engine solves the other side of the same tradeoff: the maximum sticker price an EV can carry, at your actual annual miles, before its charging savings stop being worth the premium. That's usually the more directly useful number when you're shopping, since you already know roughly how much you drive and are really trying to judge whether a specific EV's price tag is defensible, not trying to hit a hypothetical mileage target.
How we calculated this
The EV's total cost, financing, depreciation, insurance, maintenance, repairs, and charging, is recomputed at a trial price, searching for the price where it ties the gas car's total cost at your entered miles and horizon. Every other input, including the gas car's own price and MPG and the EV's charging rates, stays fixed while the search runs.
Worked example, using this page's own defaults: the EV can cost up to about$79,972 and still break even against a $26,000 gas car at 13,000 miles a year over 12 years.
What this means
- Above this price, the gas car wins even though the EV uses less energy per mile, a bigger sticker premium eventually outweighs any realistic energy savings, no matter how efficient the EV is.
- Financing terms move the justified premium almost as much as the horizon does, a shorter, cheaper loan raises how much premium is affordable, worth checking if your actual EV quote's terms differ from what you entered here.
- Run EV vs Gas Cost Calculator once you have the EV's actual price to see the full decision, including the exact dollar advantage rather than just the ceiling.
Limitations
Reports no solution if no price in a wide searched range ties the two options, meaning one vehicle wins regardless of realistic pricing. Depreciation is a flat planning estimate, not a forecast, for both vehicles. See Methodology.
Methodology
This engine combines Vehicle Economics' fixed-rate amortization model (the standard loan-payment formula run out as a full month-by-month schedule), equity and depreciation projection model (your value and loan payoff projected forward from your own depreciation figure until they cross), ownership total cost model (every ownership cost, depreciation, financing, fuel, insurance, maintenance, repairs, and fees, summed over your horizon), fuel and charging cost model (your own miles, MPG or kWh, and rates converted directly to a dollar cost), and break-even search model (a closed-form solve where one exists, otherwise a bounded search over a stated plausible range). See Methodology for the full detail.
