Child Support by Income in Iowa
This series shows a real scenario table, computed by the site’s own guideline engine, for states whose formula works from gross income. Iowa is not one of them, and this page explains exactly why rather than leaving a broken link or a guessed number.

Why Iowa is not in this series
Requires net income (no gross conversion)
Iowa guideline support (Court Rule ch. 9) is computed on each parent’s adjusted net monthly income. The engine behind this site accepts a gross-income field for Iowa for internal consistency with every other state's data shape, but it performs no gross-to-net conversion: the value supplied is used as net income directly. Feeding it a computed gross figure would silently mislabel gross dollars as net income, so this page family excludes Iowa rather than produce a number built on that mislabeling.
What to use instead
The full Iowa child support calculator on this site runs the same real guideline engine and sources as every other state page. It asks for the net-income figures Iowa's formula actually requires, rather than trying to derive them from a hypothetical weekly gross paycheck the way this series does for states with a gross-based formula.
