New York child support and spousal support calculator

The worksheet a New York court starts from, line by line, on the caps in force since March 1, 2026. Spousal support is what New York calls maintenance and most people call alimony; the three words mean one thing here. Enter annual amounts; a quick look needs only the two incomes, and every other line is there when you want it. Nothing you type here is sent to us; it stays in this browser.

How New York works these out

Child support is a percentage of the parents' combined income: 17% for one child, 25% for two, 29% for three, 31% for four and at least 35% for five or more, on combined income up to $193,000. Each parent is responsible for the share of that figure that their income bears to the total, and the parent the children live with most of the time receives the other's share. It runs until the child is 21. Childcare, health costs insurance does not cover and education are added on top, split the same way.

Maintenance runs from the higher earner to the lower. Two formulas are worked and the lower result applies, on the higher earner's income up to $241,000. Where the payer also pays child support the percentages are lower. The same formulas set temporary maintenance while a case is pending. The advisory duration for maintenance after the divorce is 15% to 30% of the marriage for a marriage of up to 15 years; 30% to 40% of the marriage for a marriage of 16 to 20 years; 35% to 50% of the marriage for a marriage of over 20 years.

The caps ($193,000 for child support, $241,000 for maintenance), the $21,546 self-support reserve and the $15,960 poverty level are adjusted on 1 March every two years with the cost of living. Above a cap the court decides on the statutory factors in NY Domestic Relations Law § 236(B)(6)(e)(1) and NY Domestic Relations Law § 240(1-b)(f), and it may depart from the guideline for the reasons the statute lists; that is why the options above are shown as arithmetic and nothing more.

Support is one line of it.
