Reading the New Hampshire Marketplace

The ACA marketplace in New Hampshire lists 46 plans from 4 issuers spread across 10 counties. The statewide average premium is $391/mo for a 27-year-old, $476/mo at age 40, and $1,012/mo at age 60, reflecting the ACA's 3-to-1 age rating band. Individual plan premiums run from $228 at the low end to $587 at the high end, before subsidies.

Geography drives most of the within-state variation: Carroll posts the highest Silver average at $412/mo, while Belknap sits at $395/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 $4,944, 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.
