Arizona Child Support Calculator (Free, Instant Results)
An Arizona Child Support Calculator can give you a quick estimate of monthly child support based on the state’s Child Support Guidelines [1]. Enter each parent’s income, parenting time, health insurance costs and other basic information to see an estimated support amount for your family.
This number is not a court order. It is not the final answer—it’s a starting point. Judges and mediators in Arizona consider parenting time, health insurance, childcare, other children supported, and adjustments that can shift the final figure. Use this estimate to understand the basics, and in mediation, turn it into a fair agreement.
How to Use the Estimate
The calculator follows the Arizona Child Support Guidelines formula, but does not account for every adjustment, credit, or unique fact of your situation. Treat the result as a reference point to discuss in a mediation meeting, not the final number that must appear in your divorce or parenting plan.
If the estimate surprises you, that is useful information. It may mean some details need to be reviewed more carefully, or that you and your co-parent need help understanding how the Child Support Guidelines apply to your family.
In mediation, we review the calculator with parents, explain the law, and help them reach their best possible agreement. Parents may follow the calculator amount, or agree to a higher or lower amount based on the best interests of the children.

An Arizona child support calculator gives you a number. Our Certified attorney-mediators help you turn that number into a real agreement.
In mediation, we’ll help you understand the Arizona Child Support Guidelines, review your real numbers, and resolve child support together with parenting time to prepare the court-ready documents you need to finalize your case.
You pay one flat fee. No hourly billing. No retainer. No surprise invoices. You stay in control. And your children stay at the center of the process.
Frequently asked questions
Arizona uses an Income Shares Model. It factors in both parents’ gross incomes, parenting time, health insurance, childcare, and support paid for other children.
Most gross income counts: wages, salaries, self-employment, bonuses, commissions, and certain benefits. Some income is treated differently or excluded. Accurate numbers from both parents give the best estimate.
Yes. More shared parenting time can reduce the monthly amount one parent pays.
It’s an estimate, not a court order. A judge has discretion to deviate from the Guidelines. In mediation, you and your co-parent decide the final number, subject to court approval.
Yes. You can use the guideline number as a starting point, then craft an agreement that fits your real-life circumstances and your children’s best interests. The court reviews and approves the final terms.
Arizona generally treats a change of 15% or more in the guideline amount as a substantial change. This often follows a job change, a parenting time shift, or a major change in childcare or health insurance costs.
