Discover what you need to know about Child Support Laws in South Carolina.
How Does South Carolina Calculate Child Support?
South Carolina calculates child support under South Carolina Code § 63-17-470 and the South Carolina Child Support Guidelines, which use an income shares model.
South Carolina estimates what parents would have spent on the child if living together and divides that obligation proportionally based on each parent’s income and custody arrangement.
The calculation generally considers:
Both parents’ gross monthly incomes
The number of children
The South Carolina guideline support schedule
Custody arrangement (including shared custody adjustments)
Health insurance premiums for the child
Work-related childcare expenses
Extraordinary medical expenses
Other court-approved deviations
South Carolina uses standardized child support worksheets to determine the presumptive support amount.
