How South Carolina calculates child support
South Carolina's child support guidelines are established by S.C. Code Regs. 114-4710 to -4750. The state uses an Income Shares model, which combines both parents’ incomes and allocates the basic support obligation between them in proportion to each parent’s share of the combined income.
This calculator applies the current guideline edition: Guidelines eff. 1/15/2024 (DSS Booklet 2819, Nov. 2024 printing).
The result is the presumptive guideline amount — the starting point a South Carolina court uses before considering deviation factors. The court-ready worksheet with the full line-by-line calculation, guideline-edition badge, and statutory citation is available in Aequis with a free 14-day trial.
South Carolina child support FAQ
How is child support calculated in South Carolina?
South Carolina sets child support under its official guidelines (S.C. Code Regs. 114-4710 to -4750), which use a income shares approach. The guideline produces a presumptive monthly amount from the parents' incomes, the number of children, and inputs such as parenting time, childcare, and health insurance costs.
Is this the exact amount a South Carolina court will order?
No. This is an informational estimate of the presumptive guideline amount. Courts can deviate based on statutory factors, and official worksheets may require inputs this calculator does not collect. Always verify against the official guidelines worksheet before relying on any number.
What income counts for child support in South Carolina?
Guidelines generally start from each parent's gross income from most sources, with state-specific definitions, exclusions, and deductions. This calculator uses gross monthly income; consult S.C. Code Regs. 114-4710 to -4750 for what your state includes.
Do overnights affect child support in South Carolina?
Many states adjust the obligation for parenting time once overnights pass a threshold, and this calculator applies South Carolina's guideline treatment of overnights where the guideline provides one. The exact effect depends on the state's formula and the parents' incomes.
