The real cost of a charged mile
EV economics come down to one conversion: efficiency in kWh per 100 miles times your electricity price. A typical crossover at 30 kWh/100mi charged at home for 17¢/kWh costs about 5.1¢ per mile — versus roughly 14.7¢ per mile for a 30 mpg gas car at $4.40 a gallon. The gap is the reason home charging dominates the value proposition.
Public DC fast charging changes the arithmetic sharply: at 40–60¢/kWh, a fast-charged mile can cost as much as a gasoline mile. That's not a flaw so much as a pricing reality — you're paying for speed and infrastructure — but it means the share of your charging done on the road is the swing variable in annual cost, which is why this calculator blends the two explicitly.
Two refinements worth knowing: charging isn't lossless (expect 8–12% overhead between the wall and the battery, slightly worse on slow Level 1), and many utilities offer EV time-of-use rates with overnight prices far below the state average — in TOU territory, scheduling your charger is free money.
