2027 Vinfast VF 8 Plus: home charging cost in Montana

At Montana's residential electricity rate of 13.77¢/kWh, a 2027 Vinfast VF 8 Plus (rated 76.1 kWh per 100 miles by the EPA) costs $10.48 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 is cheaper than gas here: 34.6% 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 2027 Vinfast VF 8 Plus charged at home in Montana costs about $1,572/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $831 a year.

Filling up the 2027 Vinfast VF 8 Plus, in dollars

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.

Ask a licensed Montana electrician to quote the install before this math becomes a real decision.
