Vehicle EconomicsEV vs Gas Break-Even Mileage
How many miles a year would you need to drive for an EV to reach total-cost crossover with gas?
Why this comes up
EV vs Gas Cost Calculator solves the break-even year at one specific mileage you enter. This engine solves the mileage threshold directly at your chosen horizon instead, so low-mileage drivers, someone who works from home, or drives a short local commute, can check whether an EV would ever catch up for them at all, rather than running the full comparison repeatedly at different guessed mileages to find out.
How we calculated this
Both candidates' total costs, financing, depreciation, insurance, maintenance, repairs, and fuel or charging, are recomputed at the same trial annual-miles figure, using the same real-financing model as EV vs Gas Cost Calculator, searching for the mileage where the two totals tie at your fixed horizon. Every other input, including both vehicles' prices and rates, stays fixed while the search runs.
Worked example, using this page's own defaults: at a 12-year horizon, the EV needs about3,877 miles a year to reach crossover, comfortably below a typical driver's mileage.
What this means
- Low-mileage drivers may never reach the EV's break-even point within a typical ownership horizon, check this threshold against your real annual miles before assuming the EV eventually wins.
- A longer horizon lowers the required mileage, since more years give energy savings more time to accumulate and offset the EV's higher upfront cost.
- Run EV Price Premium Break-Even instead if you already know your annual miles and want the price threshold rather than the mileage threshold.
Limitations
Reports no solution if no mileage within a 100,000-mile-a-year search ties the two options, meaning one vehicle wins regardless of realistic mileage. 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.
