2027 Mercedes-Benz EQS 400 4matic (SUV): home charging cost in Idaho

At Idaho's residential electricity rate of 12.8¢/kWh, a 2027 Mercedes-Benz EQS 400 4matic (SUV) (rated 43 kWh per 100 miles by the EPA) costs $5.5 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home costs a fraction of what gas would here: 65.6% less than gas per mile, here specifically.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
