A set of child-support calculators for six states, with state-specific guideline formulas and supporting guides.

Landing page captured for the 2026-11-04 issue.

For: Parents comparing child-support estimates across states
Worth noticing: Its guides cover specific calculation factors, including self-employment, 50/50 custody, health insurance, and low-income self-support reserves.

Field notes

The homepage separates state calculators from comparison tools and guides, with guides further grouped by state, income, and situation. Its examples include Texas's percentage-of-net-resources approach and New York's combined-income method up to a cap. Situation-specific topics include imputed income, health insurance, and child care; the extract does not expose the calculators' input fields.
