Between the port, the aerospace plant, the medical university, and a tourism industry that never really has an off season, Charleston's job market pulls in newcomers faster than almost any city in the Southeast. Plenty of them arrive self-employed or between employer plans, and South Carolina gives that group a wider set of tools than most states, with one number worth memorizing: 33 months, not 36.

What one person pays for coverage in South Carolina
Average monthly premiums for individual coverage. Family pricing differs; quotes are individual.

| ACA marketplace (before subsidy) | $655 avg. | State average, before tax credits (CMS Marketplace OEP, 2026).1 |
| ACA marketplace (after average subsidy) | $76 after credit | State average, after the average tax credit, among subsidized enrollees (CMS Marketplace OEP, 2026).1 |
| Employer coverage (single / family) | $682 / $2023 single / family | State average total monthly premium, single / family; employee pays about $152/mo toward single coverage (MEPS-IC, 2024).2 |

Charleston's self-employed, from charter captains to independent consultants, price from the individual marketplace benchmark above. Subsidy eligibility follows projected household income and size for the year, an estimate never guarantees the credit, and a licensed agent can run your actual household before you pick a plan.

Charleston at a glance
Charleston anchors a fast-growing coastal metro built on the port, aerospace manufacturing, military installations, and the Medical University of South Carolina, with tourism layered over all of it. Steady in-migration from the Northeast and Midwest keeps a stream of new residents shopping for coverage before their local employment settles.
| Population | County | Metro |
|---|---|---|
| ~150,000 | Charleston (FIPS 45019) | Charleston-North Charleston |
Three Charleston situations
Whit, 40, moved from New Jersey to launch a consulting practice. His first-year income projection is a guess, which makes subsidy math shaky. An extended short-term plan can hold an underwritten rate for up to 33 months while revenue stabilizes, and he re-evaluates against the marketplace each open enrollment.
Keisha, 34, hospitality manager between resort employers. Her new role starts in ten weeks with benefits after 60 days. A short-term plan with an 11-month initial term easily covers the stretch, and she cancels when group coverage begins.
Earl, 61, shrimper with diabetes. Underwriting will exclude what he most needs covered, so short-term products are the wrong shelf. A marketplace plan covers his condition without exclusions, and at his income the subsidy may do real work.
How South Carolina's rules work
South Carolina permits short-term plans with initial terms up to 11 months and renewals up to 33 months of total coverage, per state Department of Insurance bulletins. That is nearly the multi-year flexibility of Florida or Texas, but not quite: the cap is 33 months here, and anyone quoting 36 is describing a different state. The 2024 federal rule that would have squeezed these plans nationally is currently not being enforced per the August 7, 2025 tri-agency statement, leaving South Carolina's own limits in charge.
The other side of the ledger: South Carolina did not expand Medicaid. Adults earning below the federal poverty level who fit no traditional Medicaid category can fall into the coverage gap, earning too little for marketplace subsidies and too much for nothing. For those households, fixed indemnity or supplemental products are sometimes the only affordable protection, and honesty requires saying plainly that they are limited products, not major medical insurance. Marketplace plans run through HealthCare.gov with open enrollment November 1 through January 15.

Premium data methodology. 1 Marketplace premium averages reflect the average monthly premium before advance premium tax credits, the average monthly premium after advance premium tax credits among subsidized enrollees, and the percentage of enrollees receiving advance premium tax credits, for South Carolina, as reported in the Centers for Medicare & Medicaid Services (CMS) Marketplace Open Enrollment Period Public Use Files, 2026 plan year, available at cms.gov. Figures are statewide averages across all metal tiers, ages, and household sizes; your premium will differ based on your age, household, income, county, and plan selection.
2 Employer coverage averages reflect the average total monthly premium for single and family coverage at private-sector establishments in South Carolina, including both employer and employee contributions, as reported in the Medical Expenditure Panel Survey Insurance Component (MEPS-IC), Agency for Healthcare Research and Quality, 2024 tables, available at meps.ahrq.gov. Employee contribution figure reflects the average employee share of the single-coverage premium. Employer plan costs vary by employer, plan design, and firm size.
4 No federal or state agency publishes average premium data for short-term limited duration insurance or fixed indemnity insurance. Where we do not display a client-base figure for these products, it is because we do not have sufficient policy volume in that state to report a meaningful average. Short-term and fixed indemnity products are medically underwritten, are not major medical coverage, are not required to cover pre-existing conditions or essential health benefits, and do not constitute minimum essential coverage under the Affordable Care Act.
5 Medicaid and CHIP are public programs, not insurance products sold by this agency. Premiums are $0 or nominal for those who qualify; eligibility is determined by your state based on income, household size, and other factors. The figure shown describes program design, not an average. Contact your state Medicaid agency or HealthCare.gov to check eligibility.
