How Child Support Is Calculated in South Carolina
Factors That Affect Child Support in South Carolina
Technical details and legal basis
South Carolina uses the Income Shares model (South Carolina Child Support Guidelines (SC Code § 63-17-470)) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.
Important Notes for South Carolina
- • South Carolina uses the Income Shares model, combining both parents' gross incomes to determine the total child support obligation.
- • Each parent's share of the obligation is proportional to their percentage of the combined gross income.
- • South Carolina applies a shared parenting adjustment when the non-custodial parent exercises visitation for more than 109 overnights per year (approximately 30% of the time).
- • The court adds work-related child care costs, health insurance premiums for the children, and extraordinary medical expenses to the basic obligation before dividing between parents.
Example Calculation
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined income: $8,000
Step 2: Parent A's share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation for $8,000 combined and 2 children.
Step 4: Multiply by Parent A's share (62.5%).
Adjustments for health insurance, child care, and parenting time may apply.
