Child Support in North Carolina: How It's Calculated
North Carolina uses the Income Shares Model to determine child support obligations. This guide walks through how the formula works, what factors North Carolina courts consider, and how to modify or enforce an order — with links to official North Carolina resources.
Income Shares Model in North Carolina
North Carolina uses the Income Shares Model under its Child Support Guidelines. Both parents' gross incomes are combined to determine a basic obligation from the schedule, which is allocated proportionally based on each parent's income share.
North Carolina provides a shared physical custody adjustment when the child spends at least 123 overnights per year (approximately 33.7%) with the non-primary parent. North Carolina uses separate worksheets: Worksheet A for primary custody, Worksheet B for joint custody, and Worksheet C for split custody (each parent has primary custody of at least one child). Health insurance and childcare are added to the basic obligation before allocation.
Key Factors North Carolina Courts Consider
- Both parents' gross monthly income
- Number of children
- Overnights with non-primary parent — 123+ triggers the joint custody worksheet (Worksheet B)
- Child's health insurance costs
- Work-related childcare expenses
- Extraordinary expenses for the child
- Split custody situations (separate worksheet)

Step-by-Step: How North Carolina's Formula Works
Here is how North Carolina applies the Income Shares Model to calculate a child support obligation, step by step:
1. Determine each parent's income
North Carolina starts by calculating each parent's income — gross income (before taxes). The specific definition of income is set by Income Shares Model.
2. Combine incomes and find the basic obligation
Both parents' incomes are combined and compared to North Carolina's child support schedule. The schedule produces a basic child support obligation based on combined income and the number of children.
3. Add health insurance and childcare costs
Health insurance premiums paid for the child and work-related childcare expenses are added to the basic obligation before it is divided between parents.
4. Divide proportionally based on income share
The total obligation is allocated between the parents in proportion to each parent's share of combined income. The parent with the higher income share bears a larger portion of the obligation.
5. Apply parenting time credits
Overnights with non-primary parent — 123+ triggers the joint custody worksheet (Worksheet B) shared physical custody adjustment when the child spends at least 123 overnights per year (approximately 33.
