What is the South Carolina Child Support Calculator?
A South Carolina child support calculator is a tool designed to estimate the financial support a non-custodial parent is obligated to pay to a custodial parent for the care of their children. The calculation is based on the South Carolina Child Support Guidelines, which use an “Income Shares Model”. This model presumes that children should receive the same proportion of parental income they would have received if their parents lived together. Our calculator simplifies this complex process, providing an estimate that is both reliable and easy to understand.
This tool is for parents, attorneys, and legal professionals in South Carolina who need a quick and accurate estimate of child support payments. It helps in financial planning during a separation or divorce and provides a baseline for legal negotiations. It is important to note this is an estimator; a family court judge has the final authority to determine the amount. Explore our family law resources for more information.
South Carolina Child Support Formula and Explanation
The core of the South Carolina child support calculation is the Income Shares Model. The formula can be summarized as follows:
Total Child Support Obligation = (Basic Obligation + Health Insurance Premiums + Work-Related Childcare Costs)
Here’s a breakdown of the steps:
- Calculate Combined Gross Income: The monthly gross incomes of both parents are added together.
- Determine Basic Obligation: This combined income is cross-referenced with the official South Carolina Schedule of Basic Child Support Obligations. The schedule provides a base amount based on income and the number of children.
- Add Additional Expenses: The costs for the children’s portion of health insurance and any net work-related childcare expenses are added to the basic obligation to get the total obligation.
- Prorate by Income Share: The total obligation is then divided between the parents based on their percentage share of the combined gross income. The non-custodial parent’s share is typically the amount paid to the custodial parent.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Gross Monthly Income | Each parent’s income from all sources before taxes. | US Dollars ($) | $1,000 – $30,000+ |
| Number of Children | The number of shared minor children requiring support. | Count | 1 – 6 |
| Health Insurance Premium | The monthly cost to insure only the children. | US Dollars ($) | $50 – $500 |
| Childcare Costs | Monthly work-related childcare expenses, after tax credits. | US Dollars ($) | $0 – $1,500+ |

Example 1: Average Income Scenario
- Parent A (Custodial) Gross Income: $3,000/month
- Parent B (Non-Custodial) Gross Income: $5,000/month
- Number of Children: 2
- Children’s Health Insurance: $200/month (paid by Parent B)
- Childcare Costs: $400/month (paid by Parent A)
Result: Based on the SC guidelines, the combined income of $8,000 for two children yields a basic obligation of approximately $1,533. Adding the insurance and childcare brings the total obligation to $2,133. Parent B’s income is 62.5% of the total, so their share is $1,333. Since Parent B already pays $200 for insurance, their final estimated child support payment to Parent A is around $1,133 per month.
Example 2: Higher Income Scenario
- Parent A (Custodial) Gross Income: $6,000/month
- Parent B (Non-Custodial) Gross Income: $10,000/month
- Number of Children: 1
- Children’s Health Insurance: $150/month (paid by Parent A)
- Childcare Costs: $0/month
Result: The combined income is $16,000 for one child, giving a basic obligation of about $1,478. The total obligation is $1,628 after adding insurance. Parent B’s income is 62.5% of the total, making their share $1,017.50. Parent A’s share is $610.50, and since they pay the $150 insurance, their net contribution is already accounted for. Parent B’s estimated child support payment would be $1,017.50 per month. Check our divorce process guide for more details.

Key Factors That Affect South Carolina Child Support
- Gross Income of Both Parents: This is the most significant factor. The higher the combined income, the higher the basic support obligation.
- Number of Children: The obligation increases with each additional child, though not in a simple linear fashion.
- Custody Arrangements: This calculator assumes a standard sole custody arrangement. Shared or split custody arrangements involve different calculations and require a custody agreements guide.
- Health Insurance Costs: The amount paid for the children’s health coverage is added to the basic obligation and credited to the paying parent.
- Work-Related Childcare Costs: Necessary childcare expenses are also added, making a significant impact on the final amount.
- Pre-existing Support Obligations: Payments for children from a previous relationship can reduce a parent’s gross income for the current calculation.
- Alimony Payments: Alimony paid to a party in the current case can also adjust the gross income used in the calculation.
- Extraordinary Medical Expenses: Costs for things like braces or special medical needs are typically handled separately but can be ordered by a court. Learn more at our financial planning center.
Frequently Asked Questions (FAQ)
1. Is this south carolina child support calculator official?
This calculator is an estimation tool based on the public guidelines from the South Carolina Department of Social Services. While highly accurate for standard cases, the final amount is always determined by a family court judge.
2. What is included in “gross income”?
Gross income includes salary, wages, bonuses, commissions, pensions, severance pay, and investment income. It generally does not include benefits from means-tested public assistance programs.
3. How are health insurance costs handled?
Only the portion of the health insurance premium that covers the children is included. If a family plan covers the parent and two children, you would use two-thirds of the premium’s cost.
4. What if a parent is unemployed?
If a parent is voluntarily unemployed or underemployed, a judge may “impute” income. This means the court calculates support based on what the parent *could* be earning based on their skills and job history.
5. Does this calculator work for shared custody?
No. This calculator is designed for sole custody arrangements where the child lives primarily with one parent. Shared custody (where each parent has the child for over 109 nights per year) uses a different, more complex formula.
6. When does child support end in South Carolina?
Typically, child support ends when a child turns 18 or graduates from high school, whichever is later, but not beyond the age of 19. Support can be extended for a disabled child.
7. Can child support be modified?
Yes. A child support order can be modified if there is a substantial change in circumstances, such as a significant income change for either parent. For more info, see our guide on modifying support orders.
8. What about college expenses?
In South Carolina, a court may order a parent to contribute to college expenses under specific circumstances, but this is separate from the standard child support calculation for a minor.
