Arizona follows the Income Shares Model, meaning both parents’ incomes are combined to calculate the total cost of raising the child. The obligation is then divided between the parents based on their income and amount of time spent with the child.

Key calculation steps:

1. Determine each parent’s gross income

2. Account for parenting time (number of overnights)

3. Include costs for childcare, health insurance, and education

4. Adjust for other children or existing support orders

5. Use Arizona’s support schedule to determine base support

Arizona law recognizes that more parenting time can reduce the amount of child support owed. The number of overnights each parent has with the child is a key factor.

• Equal parenting time (50/50): Support is adjusted based on both income and shared time

• Sole or primary custody: The non-custodial parent typically pays a higher amount

• Parenting time is calculated on a yearly basis, and deviations may occur if the time is substantially higher or lower than standard

✅ Gross Income

Includes wages, bonuses, tips, rental income, pensions, and self-employment income.

✅ Parenting Time (Overnights)

Time spent with each parent influences how much support is owed.

✅ Other Child Support or Alimony Obligations

Amounts paid for other children or a former spouse may reduce gross income.

✅ Health Insurance Premiums

Only the portion paid for the child is considered.

✅ Work-Related Childcare Costs

Daycare or babysitting costs that allow a parent to work are shared.

✅ Extraordinary Expenses

Courts may adjust support for high medical costs, special education, or travel expenses for visitation.
