New York State Temporary Maintenance & Child Support Calculator

About the calculator: This page will help you calculate the figures a judge would consider in determining how much should be paid in spousal support (maintenance/alimony) and child support. Note that the formulas only take salary into consideration, not the specifics of any situation – for example, a child’s special needs, or parents who share parenting time equally. In court, a judge would consider many more factors in making an actual determination. Or, through mediation, you and your spouse may decide on a different amount that seems fair.

Also note that the maintenance formula only pertains to temporary maintenance – that which the higher-earning spouse would pay to the lower-earning spouse while the divorce is pending.
