Child Support Calculator

Estimate monthly child support with the common income-shares model: both parents' incomes are combined, each pays their share of a guideline amount that scales with the number of children. Use this as a planning starting point — every state uses its own tables.

Guideline % follows the federal table: 17% / 25% / 29% / 31% / 34% / 35%.
"Both pay share" applies the income-shares formula to each parent.
