Step-by-Step Calculation Breakdown ($6,500 vs $3,500 Monthly Gross, 2 Children)
Step 1: Calculate Combined Annual Income & Check $183,000 Cap
• Parent 1 ($6,500/mo = $78,000/yr) + Parent 2 ($3,500/mo = $42,000/yr)
• Combined Annual Parental Income: $120,000 (Within $183,000 statutory cap)
• Parent 1 Proportional Share: 65.0% ($6,500 / $10,000)
Step 2: Apply CSSA Statutory Child Percentage (25% for 2 Children)
• Combined Annual Basic Support: $120,000 × 25.0% = $30,000 / year
• Combined Monthly Basic Support: $30,000 ÷ 12 = $2,500 / month
• Parent 1 Pro-Rata Basic Share (65.0%): $1,625 / month
Step 3: Apportion Mandatory Add-Ons (Healthcare & Childcare)
• Health Insurance ($250) + Childcare ($400) = $650 / month
• Parent 1 Add-On Share (65.0%): +$423 / month
Estimated Total Monthly Child Support: $2,048 / month

Frequently Asked Questions

How does New York calculate child support?
New York calculates support under the Child Support Standards Act (CSSA - Domestic Relations Law § 240 / Family Court Act § 413). Support applies statutory percentage rates (17% for 1 child, 25% for 2, 29% for 3, 31% for 4, 35% for 5+) to combined parental income up to the statutory cap ($183,000), apportioned pro-rata between parents.
What is the New York CSSA statutory income cap?
New York establishes a statutory combined parental income cap (currently $183,000, adjusted every two years for CPI). For income exceeding $183,000, the court exercises judicial discretion to determine whether to apply statutory percentages or order specific add-on support.
Until what age is child support paid in New York?
In New York, parents have a legal duty to support their children until the age of 21 (unlike most states where support terminates at 18/high school graduation), unless the child is legally emancipated earlier through marriage, military enlistment, or full-time self-supporting employment.
How are mandatory add-on expenses divided in New York?
Under NY CSSA, unreimbursed health care expenses and work- or education-related childcare costs are mandatory add-ons divided pro-rata according to each parent's share of combined parental income. Educational and extracurricular expenses are discretionary add-ons.
When can a New York child support order be modified?
Under CSSA, either parent may petition for modification if: 1) Three years have passed since entry; 2) Either parent's gross income has changed by 15% or more; or 3) There is a substantial change in circumstances.
