Montana home charging cost for the 2027 Chevrolet BOLT

In Montana, home electricity runs 13.77¢/kWh — put a 2027 Chevrolet BOLT's EPA-rated 28.2 kWh/100mi against that and 100 miles costs $3.88, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 75.8% 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 Chevrolet BOLT costs roughly $582 a year to charge at home in Montana, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,821 a year.

What one full charge costs

Covering the 2027 Chevrolet BOLT's EPA-rated 262-mile range takes about 73.9 kWh, which costs about $10.17 at Montana'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 656 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Chevrolet BOLT alone ranks 30 of 400 models for efficiency; Montana alone ranks 10 of 51 states for electricity price.

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.
