How South Carolina Calculates Child Support

South Carolina calculates child support using the Income Shares Model as defined in S.C. Code §63-17-1530. Both parents' gross incomes are combined to determine the total support obligation from the state schedule. Each parent's share is then allocated proportionally based on their percentage of the combined income.

Health insurance premiums for the child, work-related childcare costs, and extraordinary expenses are added to the base obligation and shared proportionally between the parents. South Carolina also maintains a self-support reserve of $1,026 per month (2024) to ensure the obligor retains enough for their own basic needs.

South Carolina provides shared custody adjustments and considers extraordinary expenses such as special educational needs and medical expenses not covered by insurance. The court may deviate from the guideline amount when justified by the specific circumstances.
