New Jersey Child Support Calculator
New Jersey's current support workflow runs through the official weekly QuickCalc, the June 1, 2026 guideline update, Rule 5:6A, and the county child support process. Use this page to prepare the right inputs before you rely on the official New Jersey tool.
Before You Open the Official New Jersey Tool
QuickCalc works best when you organize the same weekly inputs the official form asks for.
Core inputs
- Number of children and number of people in the household.
- Sole or shared worksheet type and the non-custodial parent's parenting-time percentage.
- Weekly gross taxable income and prior support orders for both parents.
Facts that often move the result
- Child-care costs, health-insurance costs, and other add-ons.
- Other support or alimony obligations that affect guideline deductions.
- Supporting documents for the hearing or conference, because the calculator is only part of the case.

Weekly formula path
QuickCalc currently asks for weekly incomes, prior support orders, and parenting-time information rather than annual estimates.
Sole and shared worksheets
New Jersey currently routes support through different sole and shared worksheet paths depending on custody structure.
Informational only
QuickCalc currently warns that the result is informational only and that the court has final authority over the ordered amount.
How New Jersey child support is structured
- Start with both parents' income and deductions. New Jersey's guidelines use the parents' incomes, deductions, and shares rather than one parent's income alone.
- Add add-ons and support adjustments. The current NJ Child Support FAQ highlights child care, health insurance, other support, alimony, and poverty tests as part of the calculation path.
- Match the correct worksheet type. The official public calculator distinguishes between sole and shared parenting paths.
- Keep the update date in mind. The current annual update effective June 1, 2026 changed the self-support reserve and refreshed the live guideline baseline.
