Short answer: For plan year 2026, Michigan has 7 marketplace carriers offering 3,383 plan options across its 83 counties and 16 rating areas. The typical county has 4 carriers to choose from (up to 7), which makes it a competitive market. Full-price premiums for a 40-year-old run from about $345 to $1,217 per month before subsidies, with a median around $614. Most enrollees pay far less after premium tax credits.

Who Actually Sells Marketplace Plans in Michigan
Carrier availability in Michigan is decided county by county, not statewide. A carrier with a big statewide reputation may not file plans where you live, and that single fact drives more of your real options than any national comparison chart. Here is how the 7 carriers in Michigan actually cover the state's 83 counties for 2026:
| Carrier | Counties served | Share of state |
|---|---|---|
| Blue Cross Blue Shield of Michigan Mutual Insurance Company | 83 | 100% |
| Blue Care Network of Michigan | 83 | 100% |
| Priority Health | 68 | 82% |
| McLaren Health Plan Community | 60 | 72% |
| Ambetter from Meridian | 30 | 36% |
| UnitedHealthcare | 12 | 14% |
| Oscar Insurance Company | 4 | 5% |
Every one of Michigan's 83 counties has at least two competing marketplace carriers, which is better than many states and generally means more network and price choice.
Lowest-Cost Michigan Plan in Each Metal Tier (Age 40)
These are the lowest-premium plans available somewhere in Michigan at each metal level, with the deductible and out-of-pocket maximum that come with them. Premiums shown are full price before subsidies for a 40-year-old; your actual cost depends on your rating area, age, household, and income.
| Tier | Plan | Carrier | Type | Premium (age 40) | Deductible | OOP max |
|---|---|---|---|---|---|---|
| Catastrophic | Blue Cross® Select HMO Value | Blue Care Network of Michigan | HMO | $351 | $10,600 | $10,600 |
| Expanded Bronze | Bronze Classic Standard | Oscar Insurance Company | EPO | $356 | $7,500 | $10,000 |
| Bronze | Blue Cross® Local HMO Bronze Secure | Blue Care Network of Michigan | HMO | $345 | $10,600 | $10,600 |
| Silver | Clear Silver | Ambetter from Meridian | HMO | $385 | $7,000 | $7,000 |
| Gold | Standard Gold | Ambetter from Meridian | HMO | $409 | $2,000 | $8,200 |
Reading this table: notice how the premium and the deductible move in opposite directions. A Bronze plan wins on monthly cost and loses badly if you actually use care. The right tier depends on your expected utilization and, critically, whether your income qualifies you for cost-sharing reductions — which only attach to Silver plans.
What Age Does to a Michigan Premium
The ACA lets insurers charge a 64-year-old up to three times what they charge a 21-year-old for the same plan. That age curve, not your health, is the biggest driver of your sticker price. Using Michigan's lowest-cost Silver plan as the reference point:
| Age | Full-price monthly premium |
|---|---|
| Age 21 | $301 |
| Age 27 | $316 |
| Age 30 | $342 |
| Age 40 | $385 |
| Age 50 | $538 |
| Age 60 | $818 |
This is exactly why subsidies matter more as you get older: the same income at 60 buys a much larger premium tax credit than at 30, because the credit is calculated against the benchmark plan's cost in your area.
Plan Types and Metal Levels Available in Michigan
Plan types: HMO (2,619 plans), PPO (732 plans), EPO (32 plans). Plan type governs out-of-network access — HMO and EPO plans typically cover out-of-network care only in an emergency, while PPO and POS designs cover it at higher cost sharing. If keeping a specific hospital or specialist matters to you, that decision comes before price.
Metal levels: Silver (1,220), Expanded Bronze (870), Gold (786), Bronze (281), Catastrophic (226). Not every tier is offered in every county, so the mix above is statewide availability rather than a guarantee for your ZIP code.
Before enrolling in any Michigan plan, confirm your hospital and physicians participate in that specific plan's network — not just the carrier's. See how to verify a hospital is in-network.
Subsidies Change These Numbers Completely
Every premium on this page is the unsubsidized sticker price. Premium tax credits are based on household income relative to the federal poverty level and on the benchmark Silver plan in your rating area — which is why two people with identical income in different Michigan counties can receive different credits. If your income falls in the subsidy range, your net premium can be a small fraction of the figures above. If you're self-employed, the calculation runs on your net income after business deductions, which is the single most common place people misestimate and overpay. See how ACA subsidies work and the subsidy estimator.

How much does health insurance cost per month in Michigan in 2026?

Bronze plans carry the highest deductibles, and if your income qualifies you for cost-sharing reductions, a Silver plan usually delivers far better value than Bronze despite the higher premium.
Do Michigan marketplace plans cover pre-existing conditions?
Yes. Every ACA marketplace plan in Michigan must cover pre-existing conditions with no waiting period and no health underwriting, and must include the ten essential health benefits. Carriers cannot deny you or charge more because of health history. Premiums vary only by age, ZIP code rating area, household size, and tobacco use.

If you need a specific hospital or specialist, verify the network before enrolling rather than choosing on premium alone.
When can I enroll in a Michigan marketplace plan?
