2026 North Carolina Child Support Calculator — Estimate Your Monthly Obligation
To calculate North Carolina child support under NC Gen. Stat. §50-13.4, enter both parents' gross monthly incomes and the number of overnights — the Income Shares table returns the base obligation, and each parent pays their proportional share. Enter the inputs below to get an instant estimate based on North Carolina's current 2026 guidelines. The result includes a line-item breakdown showing exactly how the obligation was calculated.
To calculate accurately, you will need: (1) both parents' monthly gross income from all sources including wages, bonuses, and self-employment; (2) the number of qualifying children covered by this order; (3) the number of overnights the child spends with the non-custodial parent annually out of 365; and (4) any monthly costs either parent pays for the child's health insurance and work-related childcare. These add-ons are allocated proportionally and affect the final obligation.
North Carolina's child support guidelines under NC Gen. Stat. §50-13.4 reflect Gross income basis; shared custody adjustment at 123+ overnights. Courts in North Carolina apply the statutory formula as a rebuttable presumption — the guideline amount is the correct amount unless a party presents evidence that deviation is in the child's best interest.

Frequently Asked Questions
- How do I use the North Carolina child support calculator?
- To calculate North Carolina child support under NC Gen. Stat. §50-13.4, enter both parents' gross monthly incomes and the number of overnights — the Income Shares table returns the base obligation, and each parent pays their proportional share. Enter both parents' monthly income, the number of qualifying children, and the annual overnights for the non-custodial parent. The calculator applies the 2026 NC Gen. Stat. §50-13.4 guidelines and returns an estimated monthly obligation with a line-item breakdown.
- How accurate is the North Carolina child support calculator?
- Our calculator applies NC Gen. Stat. §50-13.4 directly and uses the current 2026 income schedule. Results are accurate for standard cases. They may differ from a court's actual order if either parent has complex self-employment deductions, there are multiple households with prior support obligations, or the case involves income imputation. Always verify with a North Carolina family law attorney.
- What income is excluded from the North Carolina child support calculation?
- Most states exclude: SSI (Supplemental Security Income), one-time gifts and inheritances, non-recurring windfalls, public assistance benefits, and income of a new spouse or partner. What counts as includable income is defined by NC Gen. Stat. §50-13.4. The calculator uses includable income only.
- What if one parent is self-employed in North Carolina?
- Self-employment income in North Carolina is gross self-employment receipts minus allowable ordinary and necessary business expenses. Courts may disallow excessive expenses. If a self-employed parent minimizes income through deductions, the court can impute income based on earning capacity, prior earnings history, or available job market data.
- Does 50/50 custody eliminate child support in North Carolina?
- Not automatically. North Carolina calculates a base obligation from both parents' incomes, then applies a shared parenting adjustment. The adjustment triggers at 123+ overnights. The parent with the higher income typically still owes some support in equal custody, reflecting the income disparity between households.
- When can North Carolina child support be modified?
- North Carolina child support can be modified when there is a material change in circumstances — typically a 15–20% change in either parent's income, a significant change in custody time, or a change in the child's needs. File a petition with the court that issued the original order. Modifications are only retroactive to the petition date.
