What the cost means for Montana
Montana's average premium of $942 is close to the national average premium. Most of the difference between states comes down to flood risk: river overflow, flash floods and heavy rainfall are the main hazards inland. Since FEMA fully adopted Risk Rating 2.0 in 2023, premiums are priced on each individual property rather than a flat zone rate — so two homes in the same town can pay very different amounts. The 2,217 NFIP claims paid in Montana since 1978 put it #44 of 51 for total claim activity.
Flood zones that matter in Montana
Montana's mapped floodplains are dominated by these FEMA flood zones. Zones beginning with A or V are high-risk Special Flood Hazard Areas where insurance is usually mandatory with a federally backed mortgage:
- Zone AE — The most common high-risk zone: the base floodplain where Base Flood Elevations (BFEs) are determined and shown on the map. (high-risk, insurance usually mandatory)
- Zone A — High-risk area subject to the 1%-annual-chance flood, with no detailed analysis, so no Base Flood Elevations (BFEs) are shown. (high-risk, insurance usually mandatory)
- Zone X (unshaded) — Minimal-risk area outside the 0.2%-annual-chance (500-year) floodplain; insurance optional and lowest-cost. (not high-risk, insurance optional)
Estimate your premium
Use the flood-insurance calculator to get a rough annual cost for Montana from your coverage amount and flood zone. For example, $250,000 of building coverage in a Zone AE area of Montana estimates near $942 a year before property-specific Risk Rating 2.0 factors. It is a benchmark, not a quote.

That ranks Montana #35 of 51 states and DC by premium. Your own cost depends on your property under Risk Rating 2.0, so treat this as a benchmark, not a quote.
Do I need flood insurance in Montana?
If your property is in a high-risk Special Flood Hazard Area (FEMA zones beginning with A or V) and you have a federally backed mortgage, flood insurance is mandatory. Montana's mapped floodplains are dominated by zones AE, A, X. Even outside high-risk zones it is optional but recommended, because roughly a quarter to 40% of NFIP claims come from lower-risk areas.
How many flood insurance claims has Montana had?
The NFIP has paid out on 2,217 flood-insurance claims in Montana since the program's records began in 1978 (OpenFEMA NFIP claims dataset), ranking it #44 of 51. Riverine and heavy-rainfall flooding drives most losses here.
Why is flood insurance more expensive in Montana?
Under FEMA's Risk Rating 2.0, premiums reflect each property's true flood risk — distance to water, flood type, foundation, elevation and rebuild cost. Montana's average of $942 is close to the national average premium, shaped by its inland river and rainfall flooding and the mix of flood zones (AE, A, X). Compare with similar states below.
