Washington Child Support Guidelines (2026 Updates)
The transition to a dual-household structure relies on the accurate calculation of support based on your combined net income of $6,600. In Whatcom County, WA, this follows the Income Shares Model to benefit 3 children.
Breakdown of the $6,600 Calculation
For a combined income of $6,600, the 2026 guidelines set the presumptive support for 3 children at $1,995. This ensures the transfer payment fairly reflects the total resources available to the family.
What This Number Means For You
If you're earning between $3,000 and $7,000 a month net, you're in the most common income range Washington courts see, and the 2026 economic table handles this tier cleanly. The SSR of $2,394 isn't a concern at this level, so the presumptive number you're looking at is likely close to what a commissioner would order. That said, close doesn't mean final — if you have your kids more than the standard custody split, a parenting time credit could meaningfully reduce what you pay. Run the full worksheet wizard to see how your actual custody schedule affects the bottom line before assuming the number on this page is what you'll owe.
Number of Children: What To Expect
With three children, deviation requests become more common because extraordinary expenses — daycare, medical costs, school fees — multiply quickly. Courts look carefully at how those costs are split proportionally between parents at this tier.
What To Do After Seeing Your Number
The number on this page is a presumptive estimate — it's where the court starts, not necessarily where it ends. Don't let it panic you before you understand what's actually negotiable. Your parenting time schedule directly affects what you pay, and even a modest increase in overnight stays can produce a meaningful credit under Washington's residential time formula. Extraordinary expenses like daycare and health insurance premiums get added on top of the base, so your real total may be higher than what you see here. You also have the legal right to request a deviation if your circumstances qualify — high debt, other dependents, or a shared custody arrangement all count. Start with the worksheet wizard to see your full picture before your hearing.
