Child support guidelines by state (2026)
This table compares the child support guidelines of the 51 jurisdictions this site covers: which model each one uses, whether it starts from gross or net income, the period its schedule is written in, where the schedule stops, how parenting time changes the amount, and the protections for low-income parents. Every value is read from the same rules files the calculators use, so the table and the calculators always agree.
Most states use the income shares model: the parents’ incomes are added together, a schedule gives the basic obligation for that combined income and the number of children, and each parent is responsible for their share. Percentage-of-income states take a set percentage of the paying parent’s income instead, and a few states use the Melson formula, which first protects a self-support amount for each parent.

How this data was collected
Each row comes from the official sources for that jurisdiction: state statutes and court rules, the state judiciary and child support agency, and official state calculators. We don’t use commercial calculators, law-firm summaries or secondary compilations. Every value is stored with the address of its source and the date it was checked, and a weekly check flags any source page that changes so the row can be reviewed.
Where we could not find a value in an official source, the row says so and links the state’s child support agency instead of guessing; those rows are left out of counts and have empty values in the CSV. Laws and guidelines change, and courts can deviate from the guidelines in individual cases, so treat this table as a research starting point, not legal advice. See the methodology for each state and theeditorial policy.
