Reading the Iowa Marketplace

The ACA marketplace in Iowa lists 121 plans from 6 issuers spread across 99 counties. The statewide average premium is $458/mo for a 27-year-old, $558/mo at age 40, and $1,185/mo at age 60, reflecting the ACA's 3-to-1 age rating band. Individual plan premiums run from $246 at the low end to $877 at the high end, before subsidies.

Geography drives most of the within-state variation: Allamakee posts the highest Silver average at $707/mo, while Polk sits at $420/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 $5,045, 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.
