Estimate EV battery capacity loss and range over years of use.
Batteries fade roughly linearly over the first years, so multiplying the annual degradation by ownership years gives the remaining capacity, which scales the range directly. Capacity loss reduces both driving range and resale value, so knowing the trajectory helps buyers budget for replacement or trade-in timing.
Battery Degradation
Capacity % = 100 - years x annual degradation%
