Arizona’s Child Support Guidelines, adopted under A.R.S. § 25-320 appendix and last updated in 2022, run the parents’ combined income through a Basic Support Obligation schedule and then adjust the result for how many days each parent has the children. The self-support reserve built into this calculator tracks the 2026 Arizona minimum wage, so the floor below which a paying parent isn’t squeezed moves with current wage figures rather than a fixed old number.
