This calculator estimates the guideline amount under New York law using the statutory figures effective March 1, 2026. It is general information, not legal advice, and using it does not create an attorney client relationship. A court or a written agreement can arrive at a different number. Nothing you enter is saved or sent to the firm.

How New York calculates child support

New York uses the Child Support Standards Act. The calculator follows the same steps a court does:

Income

Each parent’s gross income is reduced by Social Security and Medicare tax and by maintenance paid to the other parent. Maintenance received is added.

Percentage

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 do not live with pays his or her share of that amount, in proportion to the two incomes.

Child care needed for work or school, the children’s health insurance premium, and uninsured medical costs are shared in the same proportions on top of basic support. Support generally continues until a child turns 21.

What the calculator cannot tell you

Whether income should be imputed to a parent who is underemployed or paid in cash
How a court will treat combined income above the $193,000 cap
Whether a deviation from the formula is justified in your case
Deductions that apply to some parents, such as New York City income tax or support paid for other children
Self employment income, where the tax and expense rules differ

That is where the number in a real case is won or lost. If you and the other parent agree on the figures, an uncontested divorce is a flat fee. If you do not, a free consultation will tell you where you stand. For spousal support, use the maintenance calculator.

Frequently Asked Questions

Is this the amount a court will order?

It is the presumptive guideline amount on the incomes you enter. A court starts there and may adjust it, for example by imputing income, deciding how to treat income above the cap, or finding that the formula result is unjust or inappropriate.

What counts as income for child support in New York?

Generally the gross income reported on your most recent federal tax return, plus certain other income and benefits, less Social Security and Medicare tax and a short list of other deductions. The court can also attribute income to a parent based on earning ability or on money and benefits received from others.

Can we agree to a different amount?

Yes. Parents can agree to a different amount, but the written agreement has to state what the guideline amount would have been and the reasons for departing from it, and the court has to approve it.

What if we share custody equally?

With truly equal parenting time, the parent with the higher income is generally treated as the noncustodial parent and pays support under the formula, unless the parents agree otherwise and the court approves.

What happens when combined income is over $193,000?

The percentages apply automatically to the first $193,000 of combined income. For income above that, the court can apply the same percentage, apply the statutory factors, or both. The calculator shows the capped amount and what the same percentage would add.
