EV vs. Gas Cost in Montana (2026)
In Montana, gas averages about $4.37/gallon and home electricity about $0.13/kWh. Driving 13,000 miles a year, that's roughly $2,272 in gas versus about $497 to charge an EV at home — about $1,775/year before purchase price, maintenance, and resale.
The federal EV tax credit is now $0 (it ended for vehicles acquired after September 30, 2025), so these numbers don't assume a $7,500 discount that no longer exists.
