What drives EV savings in Hawaii

Your savings come down to four things: how many miles you drive, your car's MPG, the local price of gas, and your electricity rate. The calculator pulls the latest regional gas price and Hawaii's average residential electricity rate automatically, then compares the cost per mile of your current car against an EV.

Hawaii currently charges no special annual EV registration surcharge, which shortens your break-even versus states that do.
