2026 Toyota bZ (energy capacity 200 Ah): home charging cost in Montana

At Montana's residential electricity rate of 13.77¢/kWh, a 2026 Toyota bZ (energy capacity 200 Ah) (rated 25.8 kWh per 100 miles by the EPA) costs $3.56 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: 77.8% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Toyota bZ (energy capacity 200 Ah) charged at home in Montana costs about $534/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,869 a year.

Cost of a full charge

A 2026 Toyota bZ (energy capacity 200 Ah) needs roughly 61 kWh to reach its EPA-rated 236-mile range, which runs about $8.4 at 13.77¢/kWh in Montana.

Where this ranks

Before you install a home charger in Montana

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.
