How the ACA Subsidy Cliff Works in South Carolina
South Carolina residents shopping for 2026 health insurance on the federal marketplace (HealthCare.gov) face the return of the 400% FPL subsidy cliff. The benchmark second-lowest-cost silver plan (SLCSP) in South Carolina averages $564/month for a 40-year-old — adjusted up or down by the federal 3:1 age curve for other ages.
South Carolina has not expanded Medicaid, which means there is a coverage gap for some low-income residents. The ACA subsidy cliff is most relevant for South Carolina residents with income between 100% and 400% FPL.
The calculator above uses South Carolina-specific SLCSP data and the standard federal poverty guidelines to calculate your exact subsidy and show how pre-tax contributions (HSA, IRA, Solo 401k) can help you stay below the cliff.
