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.
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.
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.
