Idaho home charging cost for the 2027 Vinfast VF 7 Plus

In Idaho, home electricity runs 12.8¢/kWh — put a 2027 Vinfast VF 7 Plus's EPA-rated 44.4 kWh/100mi against that and 100 miles costs $5.68, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 64.5% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2027 Vinfast VF 7 Plus costs roughly $852 a year to charge at home in Idaho, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,551 a year.

Filling up the 2027 Vinfast VF 7 Plus, in dollars

Covering the 2027 Vinfast VF 7 Plus's EPA-rated 209-mile range takes about 92.7 kWh, which costs about $11.87 at Idaho's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

How this compares nationally

This combination ranks 7,906 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Vinfast VF 7 Plus alone ranks 352 of 400 models for efficiency; Idaho alone ranks 3 of 51 states for electricity price.

Before you install a home charger 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.
