This calculator applies Arizona's income-shares model from the 2022 Child Support Guidelines. You enter each parent's gross monthly income, the number of children, and how many parenting-time days each parent has per year. The tool combines the incomes, reads the basic support obligation from the state schedule, adds work-related child care and medical or dental costs, and divides the total in proportion to each parent's income — reducing the paying parent's share for the time the children spend in their care.
Two things move the number most: parenting time and add-on costs. More parenting-time days for the paying parent lowers the transfer, while work-related child care and the children's health-insurance premiums are added on top of the base obligation and split by income. The tool shows each of these steps so you can see exactly how your number is built.
For the official figure used in court, run the same inputs through the Arizona Child Support Calculator on azcourts.gov — our estimate simplifies the self-support-reserve step for very low incomes. Everything here is a preparation estimate, not legal advice.
Gross income from nearly all sources — wages, salary, self-employment, commissions, and often recurring bonuses — before taxes. A court can also attribute income to a parent who is unemployed or underemployed by choice.
Arizona gives the paying parent a parenting-time adjustment based on the number of days per year the children are in their care. More days generally means a lower transfer. Our calculator lets you slide the days and watch the number update.
Yes. Work-related child care and the children's medical, dental, and vision premiums are added to the basic obligation and divided between the parents in proportion to income. Enter who pays each and the tool allocates them.
It follows the same 2022 Guidelines schedule and parenting-time table and reproduces the Guidelines' worked example. For a very low-income case it simplifies the self-support-reserve step, so confirm the exact figure on the official azcourts.gov calculator.
No. It's a preparation estimate to help you understand the guideline benchmark. The court sets the actual order and can deviate for the child's best interest.
