How Arizona Child Support Works

Arizona uses the Income Shares Model for calculating child support. This model is based on the concept that children should receive the same proportion of parental income they would have received if the parents lived together.

Key Factors

  • Gross Income: Both parents' incomes before taxes and deductions
  • Number of Children: Support increases with more children, but not proportionally
  • Parenting Time: More overnight stays with the paying parent typically reduces support
  • Health Insurance: Costs for children's coverage are factored in
  • Childcare: Work-related childcare expenses are shared

Important Disclaimer

This calculator provides estimates only. Actual child support orders may differ based on specific circumstances, deviations requested by either party, and the court's discretion. For accurate legal advice, please consult with a family law attorney.
