How Child Support Is Calculated in New York

Quick Answer

How is child support calculated in New York?
New York uses a formula under the Child Support Standards Act that considers both parents’ incomes and the number of children involved. The formula provides a starting point, but courts may also consider additional expenses and family circumstances before issuing a final child support order.

When parents divorce or separate, one of the biggest concerns is often child support. Parents want to know how much support may be ordered, who pays it, what expenses are included, and whether the amount will be fair.

At Greebel & Greebel, we understand that child support is not just about numbers. It is about making sure your child has stability, support, and the resources they need while helping both parents move forward with clarity.

For more than 35 years, our firm has helped families across Long Island navigate divorce, custody, and child support matters with compassionate guidance and strong legal representation.

What Is Child Support?

Child support is money paid by one parent to help cover a child’s basic needs. In New York, child support is meant to help provide for things such as food, housing, clothing, education, and medical care. New York courts explain that child support is generally paid to help cover a child’s basic needs, and it usually continues until the child turns 21 unless the child is legally emancipated earlier.

The goal is simple: children should continue to receive financial support from both parents, even when the parents are no longer together.

How Does New York Calculate Child Support?

New York uses a formula under the Child Support Standards Act. This formula looks at the combined parental income and applies a percentage based on the number of children.

According to New York child support guidance, the standard percentages are:

Number of Children Percentage of Combined Parental Income
One child 17%
Two children 25%
Three children 29%
Four children 31%
Five or more children At least 35%

These percentages help determine the basic child support obligation. From there, the amount is generally divided between the parents based on each parent’s share of the combined income.

What Income Is Considered?

Child support is not always based on a paycheck alone. Depending on the situation, the court may consider several types of income.

This may include:

  • Wages and salary
  • Self-employment income
  • Bonuses or commissions
  • Certain benefits
  • Other income sources

Every family’s financial picture is different. That is why it is important to understand what information may be reviewed before making assumptions about what support will look like.

Does Shared Custody Mean No Child Support?

Not necessarily.

Many parents assume that if they share custody or parenting time, no child support will be required. In New York, that is not always how it works.

Even when both parents spend significant time with the child, child support may still be ordered depending on each parent’s income, the custody arrangement, and the child’s needs.

The focus is not on punishing either parent. The focus is on making sure the child is financially supported.

What Expenses Can Be Included Beyond Basic Child Support?

Child support may include more than the basic monthly support amount.

Depending on the case, additional expenses may include:

  • Childcare costs
  • Health insurance
  • Unreimbursed medical expenses
  • Educational expenses
  • Other child-related needs

These additional expenses can make a meaningful difference, especially for families balancing work schedules, medical needs, and school-related costs.

Can Child Support Be Different Than the Formula?

Yes. The formula is important, but it is not always the final word.

Courts may consider whether the standard calculation would be unfair or inappropriate under the circumstances. This can happen when there are unusual financial situations, special needs, significant income differences, or other factors that should be reviewed carefully.

This is one of the reasons it helps to speak with an experienced family law attorney before agreeing to a support amount.

Can Child Support Be Modified Later?

Yes, child support can sometimes be modified after an order is issued.

A modification may be possible if there has been a meaningful change in circumstances, such as:

  • A major income change
  • A change in custody or parenting time
  • A change in the child’s needs
  • Job loss or financial hardship

If your current child support order no longer reflects your situation, it may be worth reviewing your options.
