Washington State Child Support Schedule Worksheet Calculator

All child support orders entered in our state must apply the Washington State Child Support Schedule (WSCSS), and Worksheets must be completed and filed in every child support proceeding. To help parties estimate the amount of child support that might be ordered in their own cases, the Division of Child Support (DCS) of the Department of Social and Health Services (DSHS) created the Washington State Child Support Schedule Calculator and is happy to provide it for your use.

This version of the WSCSS Worksheet Calculator is based on the most recent changes to the child support laws in Chapter 26.19 RCW which were effective on October 1, 2009, and on the Worksheets and Instructions developed by the Administrative Office of the Courts (AOC) as required by those laws. The on-line help provided is meant only as a guide and is not intended as legal advice, or as a substitute for the statutory definitions and requirements contained in Chapter 26.19 RCW.

Keep in mind that this calculator is not meant to cover every possible fact pattern that could arise, and any amounts calculated are advisory only. The superior court judge, court commissioner, or administrative law judge has the final authority to determine the amount of child support ordered.
