Understanding Child Support Calculations

Child support calculations vary by state but generally consider several key factors. This guide helps you understand the common elements used in determining child support obligations.

Common Factors

Income of both parents: Most states use gross or net income of both parents as the primary factor. Some states impute income if a parent is voluntarily underemployed.

Custody arrangement: The amount of time each parent has physical custody significantly affects the calculation. More parenting time generally means a lower support obligation.

Number of children: Support amounts increase with additional children, though not proportionally.

Special expenses: Healthcare costs, childcare expenses, educational needs, and special needs may be factored separately.

State Models

States use one of three models: the Income Shares Model (most common), the Percentage of Income Model, or the Melson Formula. Each approaches the calculation differently.
