The Washington State Child Support Schedule Calculator, offered by the Washington State Department of Social and Health Services (DSHS) will help you create a set of Washington State Child Support Schedule Worksheets, which are required when you are a party to the entry of a child support order. The Calculator is based on the Washington State Child Support Schedule laws found in Chapter 26.19 RCW and the worksheets and instructions developed by the Administrative Office of the Courts. The Calculator can be used to estimate the amount of child support that might be ordered in your case. It is meant to be advisory only. The superior court judge, court commissioner, or administrative law judge has the final authority to determine the amount of child support ordered.
