These are benchmark premiums, not your price. Every dollar figure here is the individual rate at age 21 for a non-tobacco user, before any premium tax credit — the standard way plans are compared like for like. What you actually pay depends on your age, county, household and income. Estimate your real cost.

South Dakota Silver premiums rank 15th cheapest of 30.

Averaged across all 22 plans, Silver coverage in South Dakota costs $528 a month before subsidies — 15th lowest of the 30 states with federal-marketplace data. Premiums vary far more by county and age than this single number suggests.

Metal tiers describe roughly what share of covered costs a plan pays, not the quality of its care or network. How the metal tiers actually differ walks through the trade, and how ACA subsidies work explains why the prices below are rarely what anyone pays.

Common questions

South Dakota Silver plans, answered

What are the copays on a South Dakota Silver plan?
Copays vary plan by plan rather than by tier — the metal level sets roughly what share of total care costs the plan covers, not the individual amounts. Across the 22 Silver plans in South Dakota, deductibles average $4,545 and the out-of-pocket maximum averages $9,330. Open any plan below to see its full cost-sharing schedule, including primary care, specialist and prescription tiers.
Who is eligible for a Silver plan in South Dakota?
Anyone eligible to buy Marketplace coverage in South Dakota can pick a Silver plan — there is no separate test for the tier. What Silver uniquely unlocks is cost-sharing reductions, available if your household income is roughly 100–250% of the federal poverty level. Those reductions apply only to Silver plans, which is why Silver is usually the right choice at those incomes even though its sticker price here ($528 a month on average) is higher than Gold in some states.
What is the deductible on a South Dakota Silver plan?
The average across all 22 Silver plans in South Dakota is $4,545, with an average out-of-pocket maximum of $9,330. The range within the tier is wide, so two plans at a similar premium can differ by thousands in what you would actually pay during a year with significant care. Deductible is usually a better basis for comparison than premium alone.
Are Silver plans available in my South Dakota county?
Silver plans are sold in 66 South Dakota counties, from 3 insurers. Which specific plans you can buy depends on where you live — a plan offered in a metro county is often not sold in a rural one. Enter your ZIP code to narrow the list to plans actually available to you.
When can I enroll in a South Dakota Marketplace plan?
South Dakota uses the federal Marketplace, so open enrollment runs November 1 to January 15. Outside that window you need a qualifying life event — losing job-based coverage, moving, marriage, or a birth — to open a special enrollment period. Cheapest Silver premiums in South Dakota start at $401 a month before any subsidy.
