Missouri points to the federal CCPA ceiling
Section 454.505 prevents administrative withholding from exceeding 15 U.S.C. §1673(b).
The ceiling depends on another supported family and whether arrears exceed twelve weeks.
Start with disposable earnings
Then answer the other-family and arrears-age questions; the result is a ceiling, not necessarily the ordered deduction.
What this estimate includes
- All four CCPA support tiers
What it leaves out
- Order allocation
- Employer fee
- Ordinary-debt garnishment
