Child support is meant to reflect the child’s needs and each parent’s ability to contribute. Shane Kennedy Law, PLLC helps parents establish, modify, and enforce support with clear explanations of how the numbers are built—not just what the final line says.
Income shares in plain language
North Carolina follows an income-shares model. In general terms, the guidelines estimate what both parents together would spend on the child if the household were intact, then allocate responsibility in proportion to each parent’s income (with adjustments). That is why accurate income information—wages, self-employment, bonuses, and other includable sources—matters so much.
Worksheets A, B, and C
Which worksheet applies depends largely on the parenting schedule and family structure:
- Worksheet A — commonly used when one parent has primary physical custody (the other has fewer overnights than the shared-custody threshold)
- Worksheet B — used when parents share custody with a substantial number of overnights (shared physical custody under the guidelines)
- Worksheet C — used in split-custody situations (each parent has primary custody of at least one of the children)
Using the wrong worksheet—or guessing overnight counts—can skew the result. Custody and support often need to be planned together; see also our custody and child support pages.
Childcare, health insurance, and extraordinary expenses
Guideline calculations frequently adjust for:
- Work-related childcare costs
- Health insurance premiums attributable to the child
- Other extraordinary expenses in appropriate cases (for example, certain uninsured medical needs or special circumstances recognized under the guidelines)
Who pays a premium or childcare invoice in real life should be reflected carefully on the worksheet so the order matches reality.
Online calculators are estimates only
Public calculators and apps can be useful for a ballpark figure. They are not a court order. They may omit:
- Self-employment nuances or imputed income issues
- Correct overnight counts under your actual or proposed schedule
- High-income or deviation analysis
- Credits, arrears, or prior order history
Treat calculator output as a starting conversation, not a final answer.
Income details that change the worksheet
Guideline income is broader than a single W-2 line. Overtime patterns, second jobs, self-employment profit, and certain benefits may be part of the picture. Courts can also address situations where a parent appears underemployed. Bringing pay stubs, tax returns, and childcare or insurance invoices to a consultation saves time and reduces guesswork.
If one parent covers health insurance for the child, that cost should appear in the right place on the worksheet so the other parent’s share is calculated fairly. The same is true for work-related daycare or after-school care that exists so a parent can work.
Deviations and high-income situations
Most cases follow the guidelines. In some situations—very high combined income, special needs, or other statutory factors—the court may consider a deviation or additional analysis. Those cases need more than a quick calculator run. Documenting the child’s actual needs and each parent’s resources is part of building a supportable request.
Establishing, modifying, and enforcing
Support may be set in a standalone case or alongside divorce or custody. Later, a substantial change in circumstances—income, overnights, childcare, or medical costs—may support a modification. If payments fall behind, enforcement tools exist; if you are behind, getting advice early is better than waiting. Parents across our four-county service area often need both clarity on the number and a workable path forward.

Frequently asked questions
How is child support calculated in North Carolina?
North Carolina uses an income-shares model under the Child Support Guidelines. Parents’ incomes and certain expenses are entered on Worksheet A, B, or C depending on the parenting schedule and case type. Online calculators are estimates only.
What is the difference between Worksheets A, B, and C?
Worksheet A is commonly used in primary-custody situations; Worksheet B addresses shared (substantial overnight) parenting; Worksheet C is used in split-custody situations where each parent has primary custody of different children. The correct sheet depends on the court-ordered or proposed schedule.
Do childcare and health insurance affect the number?
Yes. Work-related childcare and health-insurance costs for the child are among the adjustments that can change the guideline amount. Extraordinary expenses may also be considered in appropriate cases.
Can support be changed later?
Often yes, if there has been a substantial change in circumstances—such as income, overnight schedule, or major expense shifts. Do not wait while arrears build under an outdated order.
