The Model 3 is about as cheap to run as a new car gets. At roughly 4 miles per kWh it's one of the most efficient EVs on sale, so each mile costs a fraction of what a 30-mpg gas sedan burns — and the gap only widens as gas prices climb.

Charged at home overnight, the Model 3 routinely costs the equivalent of paying well under a dollar a gallon. The catch is the sticker price: the savings are real, but how fast they pay back the EV premium depends on how many miles you drive and what you'd have paid for gas.

What to keep in mind
