How Child Support Is Calculated in Arizona
Factors That Affect Child Support in Arizona
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.
