Factors That Affect Child Support in Arizona

Number of children
Parenting time (overnights per year)
Health insurance premiums for the children
Work-related child care costs
Education expenses for the children
Extraordinary child-related expenses
Support obligations from other relationships
Technical details and legal basis

Arizona uses the Income Shares model (Arizona Child Support Guidelines (A.R.S. § 25-320)) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.

Important Notes for Arizona

  • Arizona uses the Income Shares model, combining both parents' adjusted gross incomes to determine the total child support obligation.
  • Adjusted gross income is calculated by subtracting court-ordered support for other children, spousal maintenance paid, and certain mandatory deductions from gross income.
  • Arizona provides a parenting time adjustment when the non-custodial parent has the children for more than 100 overnights per year (approximately 28% of the time).
  • The court may deviate from guidelines based on the best interests of the child, including educational expenses, extraordinary medical costs, or special needs.

Example Calculation

Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.

Step 1: Combined income: $8,000

Step 2: Parent A's share: $5,000 / $8,000 = 62.5%

Step 3: Look up basic obligation for $8,000 combined and 2 children.

Step 4: Multiply by Parent A's share (62.5%).

Adjustments for health insurance, child care, and parenting time may apply.

Arizona Child Support FAQ

How is child support calculated in Arizona?
Arizona uses the Income Shares model. Both parents' adjusted gross incomes are combined, and a basic child support obligation is determined from the state schedule. Each parent pays their proportional share based on their percentage of the combined income. Adjustments are made for health insurance, child care costs, education expenses, and parenting time.
What income counts for Arizona child support?
Arizona uses adjusted gross income, which includes wages, salaries, commissions, bonuses, self-employment income, rental income, dividends, pensions, and other income sources. Adjustments are made by subtracting court-ordered support for other children and spousal maintenance obligations.
How does parenting time affect child support in Arizona?
Arizona applies a parenting time adjustment when the non-custodial parent has the children for more than 100 overnights per year (about 28% of the time). As parenting time increases, the child support obligation is reduced to reflect the direct costs borne by the non-custodial parent during those overnights.
What is the maximum child support in Arizona?
The Arizona guidelines schedule extends to $30,000 in combined monthly gross income. For incomes above this amount, the court uses its discretion to set an appropriate amount, often considering the child's established standard of living and actual needs.
How long does child support last in Arizona?
In Arizona, child support generally continues until the child turns 18, or until age 19 if the child is still attending high school. Support may continue beyond these ages for a child with a significant physical or mental disability. The court may also order support for college or vocational training in some circumstances.
Is this Arizona child support calculator updated for 2026?
Yes, this calculator uses Arizona's 2022 Schedule of Basic Support Obligations from the Arizona Child Support Guidelines (A.R.S. § 25-320), last checked against the official source on May 31, 2026. The schedule itself has not changed since 2022, so the figures used here remain the current statewide standard.
How much is child support in Arizona for 1 kid?
For one child, Arizona's schedule sets the basic obligation at $413 a month when combined parental income is $2,100, $574 a month at $3,000 combined income, and $2,572 a month at the top of the schedule, $30,000 combined income. Each parent then pays a share of that amount based on their percentage of the combined income.
Does the Arizona child support calculator include alimony or spousal support?
No, this calculator only estimates child support. Alimony, called spousal maintenance in Arizona, is decided separately using different factors, such as the length of the marriage and each spouse's earning ability.
What factors determine child support in Arizona?
Arizona courts consider both parents' adjusted gross monthly incomes, the number of children, and how many overnights each parent has with the children. They also factor in health insurance premiums, work-related child care costs, education expenses, extraordinary child-related expenses, and support obligations from other relationships.
What is the self-support reserve in Arizona child support?
Arizona sets a self-support reserve of $25,212 a year, based on 80% of minimum wage rather than the federal poverty level many other states use. This reserve helps make sure the parent paying support still has enough income left over to cover their own basic needs.
