California Child Support Custody Impact Tables

A 30-volume set that highlights financial calculations in child support depending on a party’s custody percentage and their monthly net disposable income. Each volume highlights a range of income in addition to a number of children from one to ten. The California Child Support Custody Impact Tables, part of the Litigation Support Series by Jeremy J. Salvador, is a reference tool designed for family law attorneys, judges, and mediators to verify calculations, anticipate outcomes, and clearly explain child support guideline results in relation to the party’s custody percentages.

California Child Support Custody Impact Tables, Volume 1
Overview

Every Percentage Point Has a Price

The guideline formula does not treat custodial time as a footnote to income. The approximate percentage of time factor sits inside the same equation as the parents’ earnings, and moving a schedule from a 20% to a 30% timeshare can shift a support order by a meaningful amount every month.

This release covers fifteen income brackets, from $0 to $314,000 in monthly net disposable income, for households of both one to five and six to ten children. Each volume covers the full range of custodial timeshare within its bracket, so users are prepared for any scenario.

Reads Alongside the Guideline Series

These volumes are not a substitute for the California Child Support Guideline Calculations series, they extend it. Both are organized the same way, by income bracket and children count. Where a Guideline volume gives the support number for a standard timeshare assumption, the matching Custody Impact volume shows how that number moves as custodial timeshare changes within the same bracket.

How to Use Both Series Together

Start with the Guideline volume for your income bracket and children count. Then open the matching Custody Impact volume to see how the number shifts across the timeshare arrangement you are negotiating or litigating.
