At WCSSC, accuracy in child support estimation is our primary mission. Our calculator is engineered to mirror the official Washington State Child Support Schedule (WSCSS).
All calculations performed by WCSSC are based on Chapter 26.19 of the Revised Code of Washington (RCW). We specifically integrate the following standards into our algorithmic logic:
Our system has been updated to reflect the significant January 1, 2026 legislative changes, including:
We support combined monthly net incomes up to $50,000, extending beyond the previous $12,000 limit used in older versions of the schedule.
Our logic accounts for Paid Family and Medical Leave (PFML) premiums as mandatory deductions in net income calculations.
Every calculation is cross-referenced against the Washington State Department of Social and Health Services (DSHS) tools and official manual worksheets to ensure parity.
