Reading the Ohio Marketplace
The ACA marketplace in Ohio lists 189 plans from 11 issuers spread across 88 counties. The statewide average premium is $520/mo for a 27-year-old, $634/mo at age 40, and $1,347/mo at age 60, reflecting the ACA's 3-to-1 age rating band. Individual plan premiums run from $292 at the low end to $1,012 at the high end, before subsidies.
Geography drives most of the within-state variation: Knox posts the highest Silver average at $617/mo, while Ashland sits at $484/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 $5,047, 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.
