South Carolina Child Support Calculator
Estimate child support in South Carolina based on income, number of children, and custody arrangement. This is a starting point, not legal advice — every case is different.
How is child support calculated in South Carolina?
South Carolina uses the Income Shares Model to calculate child support. Both parents’ gross incomes are combined using the state child support guidelines.
Under the Income Shares model, both parents' incomes are combined and the total child support obligation is based on what the parents would have spent on the child if the household were intact. Each parent's share is proportional to their income.
How long does child support last in South Carolina?
In South Carolina, child support typically continues until the child reaches age 18. Support may end earlier if the child becomes emancipated, marries, or joins the military. In some cases, support may extend beyond the age limit if the child has special needs or is pursuing higher education.
What factors affect child support in South Carolina?
While the income shares model provides the framework, common factors include: both parents' gross or net income, the number of children, custody and parenting time arrangements, childcare costs, health insurance premiums for the children, and any special needs. Judges may deviate from guidelines in certain circumstances.
