NY Maintenance & Child Support Calculator

Maintenance: Calculated under DRL § 236-B(5-a) (post-divorce) and § 236-B(6) (temporary). Formula A uses 30% of payor − 20% of payee (standard) or 20% of payor − 25% of payee when the payor is also the child-support payor. Formula B uses 40% of combined income − payee income. The guideline amount is the lower of the two (not less than zero). The statutory payor-income cap is $241,000 effective March 1, 2026 under the biennial adjustment published by the NY Office of Court Administration.

Child Support (CSSA): Calculated under FCA § 413 and DRL § 240. Combined parental income is multiplied by 17% / 25% / 29% / 31% / 35% for 1 / 2 / 3 / 4 / 5+ children, then prorated between parents. The combined-income cap is $193,000 effective March 1, 2026. Per FCA § 413(1)(b)(5)(vii), maintenance is deducted from the payor's income and added to the payee's income before calculating child support.

FICA: Social Security tax of 6.2% on wages up to the annual SSA wage base ($183,600 for 2026, as announced by the Social Security Administration in October 2025), Medicare tax of 1.45% on all wages, plus the Additional Medicare Tax of 0.9% on wages above $200,000 under IRC § 3101(b)(2). Because this calculator uses the current-year SSA wage base, FICA totals for high earners may differ by a few hundred dollars from calculators still using the prior year's base. NYC / Yonkers income tax, self-employment tax treatment, pensions, maintenance paid to non-parties, public assistance, and SSI deductions are not currently applied — see your attorney for a full CSSA income calculation.

Add-Ons Not Calculated: Basic child support is shown here. Courts additionally prorate (i) childcare necessary for work, (ii) health insurance premiums, and (iii) unreimbursed health expenses between the parties in proportion to income (FCA § 413(1)(c)). Educational expenses and other discretionary add-ons may also apply.

Consult a matrimonial attorney before relying on these figures for any legal or financial decision. Caps effective March 1, 2026 are subject to biennial adjustment.
