Montana's median homeowners premium per policy was $1,823 in 2022 in the Treasury file, above the national $1,551 and ranked 17 of 51, after a rise of +10.2% after inflation from 2018. Only 167 Montana ZIP codes reach the file's threshold, most of them in the western valleys and the larger towns. Cascade County, Great Falls, rose fastest of the large counties, +15.4%, to $1,713. Missoula County paid $1,628 and Flathead County $1,608. The resort ZIP code 59716 at Big Sky paid $7,599, and 59730 near Bozeman $3,565. Claims were infrequent but large, $18,544 on average, ranked 8 of 51, the profile of fire and winter water losses. Nonrenewals tripled from 0.27% in 2020 to 0.90% in 2022, as insurers pulled back from wildfire areas. Montana has no FAIR plan for homes. The data stop in 2022.
The western valleys
Missoula County had 12 ZIP codes in the file and a median of $1,628 in 2022, up +10.1% after inflation. Flathead County, around Kalispell and Whitefish, paid $1,608, and Lake County, around Flathead Lake and Polson, $1,836. Both sit next to national forest, and wildfire is the risk insurers price there. The cheapest ZIP codes were 59919 in Flathead County at $1,179 and 59845 in Sanders County at $1,186.
Big Sky, Bozeman and second homes
ZIP 59716, in the Madison County part of Big Sky, paid $7,599 per policy, and 59730 in Gallatin County $3,565. Those are very large houses, often second homes, with high dwelling limits. A vacant home in a Montana winter carries a risk of freezing that many policies limit unless the heat is kept on or the water is shut off and drained. The state's range from the cheapest tenth of ZIP codes, under $1,448, to the dearest, over $2,464, is wide for a rural state.

Rare claims, large claims
Montana insurers paid 3.8 claims per 100 policies a year, ranked 35 of 51, at an average of $18,544. When losses are mostly fires, the dwelling limit decides how much of a rebuild the policy pays. Remote building sites, a short construction season and the demand surge after a wildfire push rebuild costs above what a quick estimate gives, so the calculator above is worth running with a builder's figure. The dwelling coverage page explains the replacement cost condition.
Nonrenewals and the regulator
Montana's median nonrenewal rate went 0.41%, 0.32%, 0.27%, 0.59%, 0.90% from 2018 to 2022. Montana has no residual market plan for homes listed in the Treasury report, so a home declined by admitted insurers goes to the surplus lines market. The office of the Montana Commissioner of Securities and Insurance handles complaints. Creating defensible space around the house and a fire-resistant roof can help with both renewal and price.
