2026 Porsche Macan 4S Electric: home charging cost in Idaho

In Idaho, home electricity runs 12.8¢/kWh — put a 2026 Porsche Macan 4S Electric's EPA-rated 36.8 kWh/100mi against that and 100 miles costs $4.71, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 70.6% less than gas per mile, here specifically.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Porsche Macan 4S Electric charged at home in Idaho costs about $706/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,697 a year.

Cost of a full charge

A 2026 Porsche Macan 4S Electric needs roughly 106.7 kWh to reach its EPA-rated 290-mile range, which runs about $13.66 at 12.8¢/kWh in Idaho.

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.
