Washington Child Support Calculator
Washington's current child support workflow runs through the official DCS quick estimator, the WSCSS worksheets, the January 1, 2026 schedule refresh, and the current self-support-reserve rules. Use this page to prepare the right inputs before you rely on the official Washington tool.
Before You Open the Washington Tool
The current Washington estimator works better when you organize the same information the worksheets and standard calculation rely on.
Core inputs
- Current monthly income for both parents.
- Number of children and the current parenting schedule.
- Child-care, health-insurance, and uninsured health-care expense details.
Facts that often move the result
- Whether the order falls near the $50 presumptive minimum or the self-support-reserve floor.
- Whether nonrecurring income, other children, or a residential-schedule deviation is in play.
- Whether you are setting a first order or modifying an existing one.

Official public estimator
Washington currently makes the DCS quick estimator available to the public as a preparation tool.
Live worksheet baseline
The current WSCSS forms, economic table, and instructions remain the core calculation baseline.
Current lower-limit rules matter
Washington still uses a presumptive minimum support amount and a self-support-reserve check.
How Washington child support is structured
- Start with the current WSCSS framework. Washington child support still runs through the economic table and worksheets reflected in RCW 26.19.020.
- Use current monthly income, not stale assumptions. DCS currently says the live table now spans $2,200 to $50,000 in monthly income after the January 1, 2026 refresh.
- Check the lower-limit rules. RCW 26.19.065 still matters because it handles the self-support reserve and the presumptive $50-per-child minimum.
- Screen for deviations separately. Residential schedule, nonrecurring income, debt, and other-children facts can move the final number away from the standard calculation.
- Treat the estimator as preparation, not the final order. The estimator is useful, but the official case still runs through the worksheet and order process.
Intent check
Need a Washington maintenance calculator or Washington maintenance overview instead? Use the Washington maintenance page, because maintenance follows a separate statute and factor analysis rather than the WSCSS child support framework.
Frequently Asked Questions
Does Washington have an official child support calculator?
Yes. Washington currently provides the DCS Child Support Quick Estimator as the public estimate tool alongside the official worksheets.
What changed in Washington child support most recently?
DCS currently states that the January 1, 2026 update moved the economic-table monthly income range to $2,200 through $50,000 and raised the self-support reserve to 180% of the federal poverty level.
Is the DCS quick estimator itself a court order?
No. The estimator is a preparation and screening tool. Washington support still runs through the WSCSS worksheets and the actual court or DCS order process.
What should I gather before opening the Washington estimator?
You will usually want current monthly income for both parents, the number of children, child-care and health-care costs, and any facts that may affect the standard calculation or a deviation request.
