Child Support in North Carolina: How Much Will You Owe?

Quick answer: it depends on both parents' incomes, how many children you have, and the parenting schedule. The calculator on this page turns those numbers into a real guideline estimate in about a minute. It is an educational estimate, not legal advice, and the judge always sets the final amount.

Wondering how much child support you will owe or receive in North Carolina? The state uses one formula everywhere, so the same math applies in every county. This page explains how it works, lets you run a live estimate, and links to a dedicated page for each county at the bottom.

North Carolina follows the Income Shares model under the North Carolina Child Support Guidelines under N.C. Gen. Stat. § 50-13.4. The court combines both parents' monthly gross incomes, looks up the basic support obligation on the state's guideline schedule for that income level and number of children, then prorates the obligation between the parents according to each parent's percentage share of the combined income.

What counts as income? North Carolina runs the formula on gross income, meaning income before taxes come out. Gross income from any source including wages, self-employment, severance, pensions, retirement, Social Security, workers' compensation, unemployment, and recurring gifts. Self-employment income is net of reasonable business expenses.

Parenting time matters directly in North Carolina: the number of overnights each parent has changes the math itself. North Carolina uses a shared-care formula tied to overnights. When each parent has the child for at least 123 overnights a year, the court switches from Worksheet A (primary custody) to Worksheet B (shared custody), which adjusts the basic obligation for the time each parent spends with the child. With fewer than 123 overnights for one parent, Worksheet A applies and parenting time does not change the formula. Worksheet C handles split custody where each parent has primary care of at least one child.

When does it end? North Carolina child support generally ends at age 18 but continues to age 20 if the child is still in primary or secondary school making satisfactory progress. Continuing support for disabled adult children is available.

Can the amount change later? File a motion in district court or request review through North Carolina CSS. A 15% variance or substantial change in circumstances supports modification.

If payments fall behind, North Carolina has real enforcement tools. North Carolina CSS enforces through immediate income withholding, tax intercept, license suspension, lien filings, credit reporting, and contempt referrals.

Child support cases in North Carolina are generally handled through the state's District Court, and North Carolina Child Support Services (Department of Health and Human Services) runs the state's child support services program.
