2005 Child Support Calculator

The 2005 Child Support Calculator will calculate a child support amount based on the Arizona Child Support Guidelines that took effect January 1, 2005. 

The purpose of this calculator is informational and educational only and does not constitute legal advice. The amount of child support a court will order for any particular case may be different from the amount estimated by the calculator. The court has the final authority to determine the amount of child support awarded. The amount stated by this calculator is only an estimate and is not a guarantee of the amount of child support that will be awarded. Please see an attorney for more detailed information.

This calculator is intended primarily for cases in which one parent is the sole custodian of the child(ren), although it may be used for cases in which parents share custody of the child(ren). To calculate support for cases in which the time the child(ren) spend with each parent is essentially equal, calculate support as directed below, then look on the "Parent's Worksheet for Child Support Amount" for the line titled "Child Support to be Paid By: Father or Mother". Deduct the lower amount from the higher amount, then divide by two. The resulting amount is paid to the parent with the lower obligation. See Guidelines Section 12 for more information.


Before starting the child support calculation, gather the information listed below, if applicable to your case.

  • Children’s names and dates of birth.
  • Gross income of both parents.
  • Spousal maintenance paid or received by either parent.
  • Court-ordered child support for children of other relationships.
  • Medical, dental and vision insurance costs for children only.
  • Extra education expenses paid.
  • Extraordinary child expenses paid.
  • Parenting time days per year, if not equal parenting time.
  • Court-ordered arrears paid by the noncustodial parent.

The links below will take you to Superior Court websites in each county. You will find information on filing the documents, such as how, where and costs. The last link directs you to contact information for all Clerks of Superior Court in Arizona. You may wish to call the Clerk of the Superior Court in your county to inquire about filing information.
