How Much Does Health Insurance Cost in South Carolina in 2026?

How Age Affects Your Premium

Under the ACA, insurers can charge older enrollees up to three times more than younger enrollees. This is called the age rating curve, and it has a significant impact on what you pay. A 21-year-old in South Carolina might pay $280 per month for a Silver plan, while a 64-year-old pays $840 for the exact same plan. The good news is that subsidies also scale with age - because the benchmark premium is higher for older enrollees, the subsidy amount is typically larger too.

Here is a rough guide to how age affects Silver plan premiums before subsidies in the Lowcountry: ages 21 to 29 pay roughly $280 to $350 per month, ages 30 to 39 pay $340 to $430, ages 40 to 49 pay $430 to $540, ages 50 to 59 pay $600 to $750, and ages 60 to 64 pay $750 to $840. After subsidies, many people across all age groups end up paying $100 to $300 per month. The subsidy is specifically designed to prevent age from making coverage unaffordable.

Children under 15 are rated at the same premium regardless of exact age, and children 15 to 20 are rated slightly higher. If you are enrolling a family, only the three oldest children under 21 are counted in the premium - additional children are free. This is a federal rule that applies in every state including South Carolina.

Why Coverage Type Matters Beyond the Premium

The monthly premium is the number everyone looks at first, but it is not the only number that matters. Short-term insurance might cost $150 per month compared to $300 for a marketplace Silver plan, but if you need surgery, the short-term plan might leave you with $80,000 in bills that the marketplace plan would have covered for $6,500 out of pocket at most.

Employer-sponsored coverage is usually the best deal when it is available because your employer subsidizes 70 to 80 percent of the premium. But if you lose your job, retire early, become self-employed, or your employer does not offer health benefits, the marketplace is designed to fill that gap. COBRA lets you keep your employer plan temporarily, but you pay the full premium with no employer contribution, making it the most expensive option for most people.

Here is my rule of thumb for clients in the Lowcountry: if you have access to an employer plan, take it. If you do not, check the marketplace first. COBRA only makes sense if you are mid-treatment and need to keep your current doctors. Short-term insurance is a last resort for people who are healthy, need temporary coverage, and do not qualify for marketplace subsidies.

Health Insurance Carriers in South Carolina

In the Charleston, Dorchester, and Berkeley county areas, you have three marketplace carriers to choose from for 2026. Each has different strengths, and the right choice depends on your doctors, your medications, and how much flexibility you want in choosing providers.

BlueCross BlueShield of South Carolina

BlueCross has the widest provider network in the Lowcountry. Most MUSC physicians, Roper St. Francis providers, and Trident Health System doctors accept BlueCross marketplace plans. If keeping your current doctor is a priority, BlueCross is usually the safest bet. Their premiums tend to be slightly higher than Ambetter and Molina, but the network breadth means fewer surprise out-of-network bills. BlueCross offers plans in all four metal tiers and has a well-established prescription drug formulary. For people switching from an employer BlueCross plan to a marketplace BlueCross plan, the transition is often seamless - many of the same providers are in both networks.

Ambetter from Absolute Total Care

Ambetter is the marketplace brand of Absolute Total Care, which is part of the Centene Corporation. Ambetter offers competitive premiums, particularly at the Silver and Bronze levels, and their network covers the major hospital systems in the tri-county area. The network is narrower than BlueCross, which means you need to verify your specific doctors before enrolling. Ambetter tends to be a strong choice for people who are cost-conscious and willing to work within a more defined network. Their Silver plans are often the benchmark or near-benchmark plan, which means choosing Ambetter can maximize your subsidy value.

Molina Healthcare

Molina typically offers the lowest premiums in the Lowcountry market, especially at the Bronze and Silver levels. Their network is the most limited of the three carriers, but it covers essential hospital systems and a solid base of primary care providers. Molina is a strong option for healthy individuals who want the lowest possible premium and do not need access to a large specialist network. If you rarely use healthcare beyond annual checkups and the occasional urgent care visit, Molina can save you significant money each month. Just make sure to verify that any specialists you see regularly are in network before enrolling.

Choosing the Right Carrier

The carrier decision comes down to three questions: Are your current doctors in network? Are your medications on the formulary? And are you willing to pay a higher premium for a broader network? I check all three of these for every client before recommending a plan. It takes about 15 minutes and prevents the most common enrollment mistake - choosing the cheapest plan only to discover your doctor is not covered.

What South Carolina Residents Need to Know

South Carolina has some specific characteristics that affect your health insurance options and costs. Understanding these can help you make better decisions about your coverage.

South Carolina uses the federal marketplace at HealthCare.gov rather than operating a state-based exchange. This means enrollment, plan selection, and subsidy calculations all happen through the federal system. The plans and subsidies work the same way as in states with their own exchanges - the carriers and available plans are just different.

South Carolina has not expanded Medicaid under the ACA. This means adults without children who earn less than 100 percent of the Federal Poverty Level (about $15,060 for an individual in 2026) fall into a coverage gap - they earn too much for traditional Medicaid but too little for marketplace subsidies. If you are in this situation, your options are limited to short-term insurance, health sharing ministries, or community health centers that offer sliding-scale fees. This is a frustrating reality for thousands of South Carolinians, and it is one of the most common issues I help people navigate.

Open Enrollment for 2026 marketplace plans ran from November 1, 2025, through January 15, 2026. If you missed Open Enrollment, you can still enroll if you have a qualifying life event such as losing employer coverage, getting married, having a baby, or moving to a new county. These Special Enrollment Periods typically last 60 days from the qualifying event.
