- Montana averages around $2,268/year — moderate overall, but rising from wildlife and winter driving costs
- Rates rose +16% since 2023 — rural geography inflates repair costs due to limited shop density
- Wildlife collisions (deer, elk, moose) drive comprehensive claims at rates far above most states
- State Farm and GEICO are the primary options; fewer national carriers actively compete in Montana
- Full coverage is particularly important here — wildlife-related damage is near-certain over any multi-year period
Montana is a mid-priced state for auto insurance, with a statewide average of $2,268 per year for full coverage. That's roughly in line with the national average of ~$2,500, but averages mask a wide range. Urban drivers in Billings and Missoula pay meaningfully more than rural drivers on the high plains, where low traffic density and few uninsured drivers keep costs down.
Weather risk is the primary rate driver in Montana. Severe hail, ice, and deer collisions — Montana has one of the highest deer strike rates in the country — push comprehensive claims higher than the state's relatively low accident rates would suggest. Carriers price these risks into premiums across the state, even in areas with light traffic.
How to find the best rate in Montana
Because Montana has relatively few major urban centers, carrier competition can be thinner than in coastal states. That makes comparison shopping especially important — not every carrier writes aggressively in every Montana ZIP code. Getting 3–4 quotes at renewal is the most reliable way to find savings of $300–$600 per year.
Montana average: $2,268/year full coverage. National average: ~$2,500. Montana drivers pay slightly below the national average, but individual rates vary widely by ZIP and carrier.

Enter your ZIP to compare.
What are Montana's minimum auto insurance requirements?
Montana requires 25/50/20 liability coverage — $25,000 per person / $50,000 per accident bodily injury and $20,000 property damage. Montana is a tort state with no mandatory PIP. Uninsured motorist coverage is required unless waived in writing. Montana's road conditions — including wildlife and winter weather — make comprehensive coverage worthwhile even on older vehicles.
Why is Montana one of the cheapest states for auto insurance?
Montana's very low population density, rural road network, and limited urban congestion mean fewer accidents per driver and lower claims costs. Billings and Missoula are the largest cities but remain small by national standards. The limited regional carrier competition is offset by national carriers pricing aggressively for Montana's low-risk driver pool.
Should I carry comprehensive coverage in Montana?
Yes — Montana has significant deer-vehicle collision risk, particularly in rural areas and at dawn/dusk. Comprehensive coverage pays for animal strikes, hail damage (Montana can see hail), and theft. Given Montana's low base rates, the incremental cost of comprehensive is relatively small compared to the risk. If your vehicle is worth more than $5,000, comprehensive is generally worth carrying.
