Arizona Child Support Calculator 2026

Possibly. A.R.S. section 25-320 requires the supreme court to review the guidelines at least every four years, and the review of the 2022 Guidelines started in January 2024 with a dedicated subcommittee and public comment. As of August 2026 no replacement has been adopted, so the 2022 Guidelines still govern every new order. We track the review and will re-verify this page when an administrative order lands.

By closeness, not by math between rows. The schedule steps by $50, and Section III.A of the guidelines says to use the row closest to your combined income, rounding up when you sit exactly in the middle. Combined income of $5,252 uses the $5,250 row; $5,275 would round up to $5,300. Many unofficial calculators interpolate instead, which produces numbers the official calculator will never show.

No, and the guidelines print examples to prove it. At 164 or more days each, the Parenting Time Table credits the paying parent 0.50 of the basic obligation, but the parent with the higher income still owes their larger share. With $5,000 and $3,000 incomes and two children, the higher earner pays $203 a month even with perfectly equal time. The transfer only reaches zero when incomes and directly paid expenses are equal too.

The Older Child Adjustment adds 10 percent of the basic obligation for each child who is 12 or older. When only some children qualify, the guidelines prorate: each child is assigned an equal slice of the basic obligation and the 10 percent applies to the older children’s slices. It reflects the higher cost of teenagers and it applies automatically, not as a deviation.

A floor that keeps the paying parent above bare subsistence. The SSR equals 80 percent of full-time monthly earnings at the Arizona minimum wage, so it moves every January when the wage does; for 2026 it is 80 percent of $2,626, or $2,100.80. If income minus the SSR is less than the guideline amount, the court may set the order at the remainder instead, after checking the receiving household’s own position. It is a built-in test, not a deviation.

Yes, two, and both are provided statewide through the Superior Court in Maricopa County: an interview-style web calculator aimed at self-represented parents and an Excel workbook version used by professionals. Older calculators stay posted for orders under prior guidelines. This page follows the same 2022 guideline math with every step cited, but the official tools and the court’s worksheet control the enforceable number.

The schedule stops and the $30,000 row becomes the presumptive basic obligation. A parent who wants more than that carries the burden of showing a higher amount is in the children’s best interests. There is no automatic percentage add-on above the cap, which makes Arizona different from states that extrapolate.

Usually yes. A.R.S. section 25-320(N) presumes each parent can work full time at least at the higher of the state or federal minimum wage, which is $15.15 an hour in Arizona for 2026. The presumption bends for good reasons: no income is attributed to an incarcerated parent, and courts can decline to attribute for disability, schooling, a child’s unusual needs, or childcare costs that would eat the paycheck.
