How New York calculates support
The Income Shares combines BOTH parents' incomes, looks up the guideline support amount for that combined income and the number of children, then splits the obligation between the parents in proportion to their incomes. Parenting time, health insurance, and childcare costs adjust the result.
New York uses the Child Support Standards Act (CSSA): fixed percentages (17%/1 child, 25%/2, 29%/3, 31%/4, 35%+/5+) applied to combined parental income up to a statutory cap (adjusted biennially; $193,000 combined, effective March 1, 2026). Above the cap courts have full discretion. This estimate may diverge significantly from official CSSA calculations.
Before any court filing, confirm your number with New York's official calculator or worksheet.
