How Child Support Is Calculated in New Jersey

New Jersey uses an Income Shares Model, which assumes children should receive the same proportion of parental income they would if the parents lived together. The court follows Appendix IX of the New Jersey Court Rules, which includes worksheets and tables to determine support.

Key elements:

  1. Gross income of both parents

  2. Number of children

  3. Parenting time adjustments (overnights)

  4. Health insurance & childcare costs

  5. Deductions for other obligations

  6. Support guidelines schedule (Appendix IX-F)

Parenting Time & Support in New Jersey

Parenting time plays a significant role in determining child support. There are two primary parenting time categories:

  • Parent of Primary Residence (PPR): The parent with more than 50% overnights

  • Parent of Alternate Residence (PAR): The noncustodial parent

If the noncustodial parent has over 104 overnights per year, a shared parenting worksheet is used, which typically lowers the support amount due to more equal time and direct spending.

What Affects Child Support in New Jersey?
