How child support is calculated in New Jersey

This version estimates a sole-parenting award without a parenting time adjustment. It uses weekly guideline net income, not gross monthly wages. Appendix IX-B rounds dollars to whole numbers and income-share ratios to two decimal places. Combined income is matched to the nearest $10 schedule row. The paying parent's share of the total obligation is reduced by that parent's direct payments.

Official sources and effective dates

Appendix IX-F, complete Schedule of Child Support Awards, effective September 1, 2025. The table runs from $180 through $3,600 combined net weekly income and has columns for one through six children.
Appendix IX-B, worksheet instructions, including amendments effective June 1, 2026. See General Information and sole-parenting lines 6 through 27.
Appendix IX-A, including amendments effective June 1, 2026. See paragraphs 7(h), 9, 13 through 18, and 20.
Appendix IX-C sole-parenting worksheet, Revision September 1, 2021. Current reserve amounts come from the 2026 rules, not a historical dollar figure on a worksheet.

A worked example

Parent A has $1,200 and Parent B has $800 in guideline net weekly income. For one child the $2,000 schedule row is $425. Parent A's rounded income share is 0.60, so the no-add-on sole-parenting amount is $255 weekly. This is an illustrative worksheet calculation, not a published official case example.

What does this version leave out?

This version does not estimate shared or split parenting, PAR Time credits, derivative benefits, other-dependent adjustments, college support, extraordinary expenses, or the age adjustment. Appendix IX-A paragraph 17 requires a 14.6 percent increase when the initial order is entered at age 12 or older. Select separate review if that rule applies or you are unsure. Childcare must already be net of the applicable Appendix IX-E tax credits. Recurring medical expenses must already exclude the first $250 per child annually.

Reserve and schedule limits

The self-support reserve is $460 weekly under the 2026 rules. A reserve reduction requires that the custodial parent's income after that parent's support share remain above the reserve. Very low-income cases and exact reserve boundaries need separate review. Below $180 or above $3,600 combined weekly net income, the court must determine an appropriate award. The schedule is not extrapolated.

Pending changes

This estimate uses the September 1, 2025 schedule and the June 1, 2026 rule updates. No later effective amendment was located in the official materials reviewed on November 6, 2026. The rules should be checked again before any publication.
