Child support uses specific inputs
Child support is not a flat percentage, and this site does not calculate it. California has official child-support information through California Courts, county Family Law Facilitators, and Judicial Council information about guideline support calculators. The California Child Support Services online calculator currently carries an official decertification warning because it does not yet reflect certain tax changes from 2025 federal legislation. The state page says users may continue to use it for an estimate, but some tax calculations may not be correct. If you already have a support estimate from an official resource, attorney, mediator, court document, or other qualified source, you can enter it here to test your monthly budget. If you do not have an estimate, leave the support field blank or run a no-support scenario.
Parenting schedules can affect financial inputs
Parenting schedules can affect childcare costs, transportation costs, work hours, housing needs, and support estimates. Because those details are personal and legally sensitive, this calculator does not convert parenting time into a support amount or custody prediction.
Check current calculator status
Child-support rules and calculators can change. Use current California Courts and Judicial Council resources, and check the warning on any calculator page before relying on an estimate.
A calculator estimate is not a court order
A calculator estimate is not the same as a court order. This website cannot tell you what a court will order in your specific situation. If child support is a major part of your budget, confirm the number through an official court resource, county Family Law Facilitator, or qualified professional before relying on it.
How to use this article
Use official California child-support information, Judicial Council calculator-status information, county Family Law Facilitator help, or a qualified professional for support questions. Use this site's calculator only to test how a support estimate you already have would affect your monthly budget.
