New York child support calculator

How New York calculates child support

• Each parent’s income is gross income minus Social Security and Medicare taxes, New York City or Yonkers income tax, and support already paid under another order.
• The two incomes are added. The combined income, up to $193,000, is multiplied by 17% for one child, 25% for two, 29% for three, 31% for four and at least 35% for five or more.
• The parent the children live with less pays a share equal to their part of the combined income. With equal time, the parent with the higher income pays.
• Low-income rules: if paying would leave that parent below the $21,546 self-support reserve, the amount drops to the greater of $600 a year or their income above the reserve; below the $15,960 poverty guideline it is $300 a year.
• Child care costs needed to work or study are shared in the same proportion.

What the calculator asks

• How many children is the support for?
• Who do the children live with more than half the time?
• Is either of you paying, or asking for, spousal maintenance from the other?
• Your gross income for the year
• Social Security and Medicare taxes you paid for the year
• New York City or Yonkers income tax you paid
• Child support or alimony you already pay under another order
• The other parent’s gross income for the year
• Social Security and Medicare taxes the other parent paid
• New York City or Yonkers income tax the other parent paid
• Child support or alimony the other parent already pays under another order
• Yearly child care cost so the parent who receives support can work or go to school

It never asks for names, Social Security numbers or account numbers, and your answers are not saved.

What the estimate leaves out

• Spousal maintenance between the parents
• Health insurance premiums and unreimbursed medical costs
• Educational and other discretionary add-ons
• Support on combined income above $193,000, which the court decides
• Other income definitions and deductions in FCA § 413(1)(b)(5) (for example business expenses or imputed income)

When a situation is outside what the calculator covers, it says so and points you to the official worksheet instead of guessing.
