EV vs. Gas Cost in Montana (2026)
Run the numbers for your situation →
Calculate your Montana EV vs gas costsIn Montana, gas averages about $4.29/gallon and home electricity about $0.13/kWh. Driving 13,000 miles a year, that's roughly $2,231 in gas versus about $497 to charge an EV at home — about $1,734/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.
In Montana, home electricity averages about $0.13/kWh while gas runs around $4.29/gallon (AAA average, as of Aug 2026 — gas prices change often; edit for your area). At those prices, charging at home costs a fraction of what it costs to fuel a comparable gas car per mile.* Whether an EV actually pays off for you depends on your annual miles, how long you keep the car, and the vehicle prices you compare — run your own numbers to see your break-even point.
* This is a general cost comparison based on average state electricity and gas prices, not a calculated break-even. Actual savings depend on your specific vehicles, mileage, charging mix, and how long you keep the car, and energy prices change over time.
