Disclaimer

This calculator is provided for informational and educational purposes only. It is a general tool based on publicly available formulas under the New York Child Support Standards Act (CSSA) and related statutory guidelines.

It does not constitute legal advice, does not create an attorney–client relationship, and should not be relied upon as a substitute for individualized legal counsel.

The calculator is intended to provide a general estimate of how child support may be calculated under New York law. Actual child support obligations may vary significantly depending on numerous case-specific factors, including but not limited to:

  • Each party’s verified income and applicable statutory deductions

  • The parenting schedule and custodial arrangement

  • Childcare, health insurance, and other add-on expenses

  • Deviations from the statutory formula

  • Income caps and statutory adjustments

  • Court discretion and judicial interpretation

  • Tax considerations and other financial circumstances

Use of this calculator does not guarantee any particular legal outcome, and results may not reflect what a Court would ultimately order or what parties may agree upon in settlement.

For advice specific to your situation, you should consult a qualified New York family law attorney.

By using this calculator, you acknowledge that it is provided “as is,” without warranties of any kind, and that Clark Peshkin and its attorneys are not responsible for any errors, omissions, or outcomes resulting from its use.
