NJ child support calculator

New Jersey child support is calculated weekly from both parents’ net income: the paying parent owes their share of the schedule amount, minus a credit for parenting time. With weekly net incomes of $1,300 and $900, one child and 80 overnights, that is about $227 a week under the schedule in force since September 1, 2025.

How the NJ child support calculator works

This NJ child support calculator follows the New Jersey Child Support Guidelines in Appendix IX of the Rules of Court, using the Appendix IX-F schedule revised effective September 1, 2025.[1][2]

  1. Weekly net income: gross taxable income minus withholding taxes, mandatory retirement contributions, union dues and support paid for other dependents. Voluntary 401(k) contributions are not deducted.[3]
  2. Basic support: the schedule amount for combined net income, at the nearest $10 (a $5 remainder rounds up).
  3. Add-ons: net work-related child care and the children’s health insurance premium.
  4. Shares: the noncustodial parent owes their income share of the total, minus what they pay directly.
  5. Parenting time credit: basic support × the noncustodial parent’s share of overnights × 37%, for variable expenses during their time.[2]
  6. Self-support reserve: the paying parent keeps 150% of the poverty guideline, if the other household is above it.

The New Jersey schedule of child support awards

The schedule gives weekly basic support from $180 to $3,600 of combined net income in $10 steps; above $3,600 the top amount is the minimum and the court adds a discretionary amount.[1]

Selected rows of Appendix IX-F (weekly, effective September 1, 2025)
Combined weekly net income1 child2 children3 children4 children
$500$172$224$248$277
$1,000$293$339$390$435
$1,500$369$420$499$557
$2,000$425$481$589$657
$2,500$481$538$674$752
$3,000$561$605$769$858

Below $180 a week the court sets an award between $5 and the $180 amount based on the paying parent’s income and expenses. The schedule must not be extrapolated beyond $3,600.[1]

Parenting time: the credit and the shared worksheet

Below 28% of overnights, the paying parent receives a credit of basic support × their overnight share × 0.37; with 20% of overnights and $100 of basic support, the credit is $7.40.[2] From 28% (about two overnights a week) with separate living accommodations, the shared parenting worksheet credits fixed and variable expenses separately, but a shared award is at the court’s discretion.[2][3]

Self-support reserve

The reserve is 150% of the federal poverty guideline for one person: $460 a week with the 2026 guideline.[2][5] If paying the award would leave the parent below it, and the other household is above it, the award is reduced to the parent’s net income minus the reserve. The guidelines’ dollar figures are updated each year; the June 1, 2026 update also revised the tax tables used to compute net income.[4]

Other New Jersey rules

  • If the first order is entered when a child is 12 or older, the award is increased by 14.6%.
  • Split parenting: two sole-parenting awards are calculated and netted.
  • Alimony set at the same time is decided first and moved from the payer’s income to the recipient’s.
  • Courts can deviate for the factors listed in Appendix IX-A, with reasons stated.[2]

Official New Jersey calculator and agency

New Jersey’s QuickCalc applies the guidelines and the official tax tables to gross income; New Jersey Child Support handles applications and payments.[6][7]

Neighboring New York uses fixed percentages of combined income (New York child support calculator) and Pennsylvania a monthly net-income schedule (PA child support calculator). Indiana is the other weekly state (Indiana child support calculator).
