Reading the Michigan Marketplace
The ACA marketplace in Michigan lists 116 plans from 7 issuers spread across 83 counties. The statewide average premium is $525/mo for a 27-year-old, $640/mo at age 40, and $1,359/mo at age 60, reflecting the ACA's 3-to-1 age rating band. Individual plan premiums run from $283 at the low end to $998 at the high end, before subsidies.
Geography drives most of the within-state variation: Alger posts the highest Silver average at $735/mo, while Genesee sits at $493/mo, a gap shaped by local issuer competition, hospital pricing, and risk-pool composition rather than benefit differences, since every marketplace plan must cover the same 10 essential health benefits. The statewide average annual deductible is $5,919, the amount most enrollees must pay before non-preventive coverage begins.
Premium tax credits (APTCs) further reduce what most enrollees pay out of pocket, with the size of the subsidy keyed to each county's benchmark (second-lowest Silver) premium.
