CoBalance helps you track due dates, payments, and payment history while keeping child support separate from shared expenses.
How North Carolina calculates child support
North Carolina uses an Income Shares model under the statewide child support guidelines. Both parents’ adjusted gross incomes identify a starting amount from the official schedule.
Worksheet A applies when one parent has at least 243 overnights per year. Worksheet B applies when each parent has at least 123 overnights and each assumes financial responsibility while the children are with that parent. Worksheet B multiplies the basic amount by 1.5, then applies each parent’s income share, overnight share, and eligible expense credits.
This free calculator supports Worksheets A and B for children who share one schedule. Use the official North Carolina calculator for Worksheet C split custody or a court worksheet.
Frequently asked questions
Is this the official North Carolina child support calculator?
No. This is a free educational estimate based on North Carolina’s official guidelines and Worksheet A or Worksheet B. Use the official state calculator for court worksheets.
How is North Carolina child support calculated?
North Carolina uses an Income Shares model. The official schedule provides a starting amount, then the appropriate worksheet applies income shares, overnights, health insurance, childcare, and payer credits.
Is my information private?
No account is required. Your entries are sent securely to calculate the estimate, and CoBalance does not store the income or parenting-time details you enter.
When does North Carolina use Worksheet B?
Worksheet B applies when each parent has at least 123 overnights per year and each assumes financial responsibility while the children are with that parent. At 122 overnights or fewer, Worksheet A applies instead.
Do I need both parents’ incomes?
Yes. North Carolina’s Income Shares guidelines start from both parents’ gross monthly incomes. If you are unsure of the other parent’s income, try a reasonable range and compare estimates.
How accurate is this North Carolina child support estimate?
It follows the official Worksheet A and Worksheet B formulas for the common inputs on this page. It does not include split custody, existing support or other-child deductions, extraordinary expenses, court deviations, or combined income above the published schedule. Treat it as a planning starting point.
Can I use this instead of talking to a lawyer?
No. This is a planning estimate, not legal advice or a court order. Use it to understand a possible outcome, then talk with your co-parent, mediator, attorney, or child-support agency. After support is set, the child support payment tracker can help keep due dates and payment history clear.
What if the children have different living arrangements?
Different living arrangements may require Worksheet C or a combined Worksheet B calculation. Use the official North Carolina calculator.
