How Much Does Health Insurance Cost in South Carolina? (2026 Real Numbers)
The honest answer is: it depends on one question nobody asks you up front — do you qualify for a subsidy? In South Carolina, that single fact decides whether you're paying $200 a month or $1,200 a month for similar coverage.
Marketplace (HealthCare.gov) prices in South Carolina
If your household income is roughly between 100% and 400% of the federal poverty level, HealthCare.gov applies a premium tax credit and your net cost can be a few hundred dollars a month or less. Above that line — and the enhanced subsidies that briefly extended help above 400% expired after 2025 — you pay the full sticker price. For a healthy 40-year-old in Charleston, full-price Silver plans from BlueCross BlueShield of South Carolina, Ambetter, Molina, and Aetna CVS Health commonly run $550–$850 a month in 2026; a family of four is often $1,500–$2,500.
Private plan prices in South Carolina
Private shared-network plans are priced on age and health instead of income. For a healthy individual in South Carolina, PPO plans on the Cigna, Aetna and PHCS PPO networks typically run $290–$460 a month at age 30, $360–$520 at 45, and $430–$600 at 60. Families land roughly $800–$1,300. Those numbers assume you pass a short health questionnaire — these plans aren't guaranteed-issue.
What moves the number
Age (marketplace plans can charge a 64-year-old three times what a 21-year-old pays; private plans are banded by age too), tobacco use, whether you're covering a spouse or children, the deductible you choose, and — for marketplace plans only — your income. South Carolina has a state income tax, so the self-employed health premium deduction reduces both federal and state taxable income.
The South Carolina-specific wrinkle
South Carolina didn't expand Medicaid, and most marketplace plans here are narrow-network HMOs — which is why a national PPO is the thing self-employed buyers ask about first.
So what should you expect to pay?
If you qualify for a subsidy: use it, and compare HealthCare.gov plans. If you don't and you're healthy: you should expect to pay less than full marketplace price, usually meaningfully less, on a private PPO. If you don't qualify and you have a serious pre-existing condition: the marketplace is still your best option, and a licensed agent should tell you that rather than sell you something that won't cover you.
