How child support is calculated in North Carolina

What decides the amount, where to get the real number, and the extra rules.

Checked against official sources: Oct 25, 2026.

Short answer

North Carolina uses the income-shares model: both parents' incomes count, and each parent pays a share of the child's support. Both parents' adjusted gross incomes are added together. The Schedule of Basic Support Obligations shows the support for that combined income and number of children, and each parent's share is in proportion to income.

Health insurance in North Carolina

The order must address the child's health care. Health insurance is reasonable in cost if covering the child costs the parent no more than 5% of the parent's gross income (cost of adding the child, child-only coverage, or the difference between self-only and family coverage). The court may also order dental or vision insurance and split uninsured expenses.

If the paying parent earns little in North Carolina

If the paying parent's adjusted gross income is under $1,150 a month, a minimum order of $50 a month is set unless the judge deviates. Above that, the schedule includes a self-support reserve based on the 2022 federal poverty level for one person ($1,133 a month); in the shaded area of the schedule, support is based only on the paying parent's income.

State guidelines may not treat time in jail or prison as choosing not to work, when support is set or changed.

Law: 45 CFR 302.56(c)(3)

How this kind of formula works

The income-shares model looks up an amount for the parents' combined income, then splits it by each parent's share of that income. Parenting time and costs can change it.

Every state must have one set of child support guidelines, review them at least every 4 years, and use the guideline amount unless a written finding says it would be unjust.

Law: 45 CFR 302.56
