These are benchmark premiums, not your price. Every dollar figure here is the individual rate at age 21 for a non-tobacco user, before any premium tax credit — the standard way plans are compared like for like. What you actually pay depends on your age, county, household and income. Estimate your real cost.

One carrier files 62% of Montana's Silver plans.

Blue Cross and Blue Shield of Montana accounts for 21 of the 34 Silver plans in Montana. A long plan list can look like a wide choice while most of it resolves to one network and one formulary — worth knowing before you treat plan count as a measure of competition.

Montana Silver premiums rank 18th cheapest of 30.

Averaged across all 34 plans, Silver coverage in Montana costs $556 a month before subsidies — 18th lowest of the 30 states with federal-marketplace data. Premiums vary far more by county and age than this single number suggests.

Metal tiers describe roughly what share of covered costs a plan pays, not the quality of its care or network. How the metal tiers actually differ walks through the trade, and how ACA subsidies work explains why the prices below are rarely what anyone pays.

Common questions

Montana Silver plans, answered

What are the copays on a Montana Silver plan?
Copays vary plan by plan rather than by tier — the metal level sets roughly what share of total care costs the plan covers, not the individual amounts. Across the 34 Silver plans in Montana, deductibles average $5,593 and the out-of-pocket maximum averages $8,543. Open any plan below to see its full cost-sharing schedule, including primary care, specialist and prescription tiers.
Who is eligible for a Silver plan in Montana?
Anyone eligible to buy Marketplace coverage in Montana can pick a Silver plan — there is no separate test for the tier. What Silver uniquely unlocks is cost-sharing reductions, available if your household income is roughly 100–250% of the federal poverty level. Those reductions apply only to Silver plans, which is why Silver is usually the right choice at those incomes even though its sticker price here ($556 a month on average) is higher than Gold in some states.
What is the deductible on a Montana Silver plan?
The average across all 34 Silver plans in Montana is $5,593, with an average out-of-pocket maximum of $8,543. The range within the tier is wide, so two plans at a similar premium can differ by thousands in what you would actually pay during a year with significant care. Deductible is usually a better basis for comparison than premium alone.
Are Silver plans available in my Montana county?
Silver plans are sold in 56 Montana counties, from 3 insurers. Which specific plans you can buy depends on where you live — a plan offered in a metro county is often not sold in a rural one. Enter your ZIP code to narrow the list to plans actually available to you.
When can I enroll in a Montana Marketplace plan?
Montana uses the federal Marketplace, so open enrollment runs November 1 to January 15. Outside that window you need a qualifying life event — losing job-based coverage, moving, marriage, or a birth — to open a special enrollment period. Cheapest Silver premiums in Montana start at $382 a month before any subsidy.
