Calculate the EV’s extra upfront and financing cost after confirmed incentives. Divide that by expected annual operating saving for a simple break-even estimate. Then compare that period with how long you realistically keep cars.
- Run low-, base- and high-mileage cases.
- Run home-charging and mostly-public-charging cases if your housing situation may change.
- Keep incentives at zero until eligibility and approval are verified.
- Use a conservative resale range rather than one optimistic number.
- Compare monthly cash flow as well as five-year total cost.
