This calculator provides an educational estimate only. Actual court orders may vary based on specific circumstances. This tool is not a substitute for legal advice from a qualified attorney. This is an estimate only, not legal advice.

This version has a limited scope. This version covers two parents, one uniform parenting schedule, and a selected payer who has fewer than 164 whole parenting days. Fractional days, equal or near-equal time, different schedules, reverse transfers, other-family adjustments, benefits, default or historical-guideline cases, discretionary expenses, and self-support reserve reductions require separate review. Income preparation and taxes are not calculated here.

Other circumstances

How child support is estimated in Arizona

The complete schedule contains 586 rows from $750 through $30,000 combined adjusted monthly Child Support Income and columns for one through six children. Section III.A uses the closest $50 row and rounds exact midpoint ties upward. Above-schedule cases need separate review in this version.

Official sources and dates

Administrative Order 2022-116 and attached guidelines, effective January 1, 2022, revised September 21, 2022. See Sections II.C, III.A, III.B.2 through III.B.4, III.B.7, IV, V.D, VI, VIII, X.A.4, and the complete schedule.
U.S. Department of Labor state minimum wage table, updated November 5, 2026. The Arizona rate is $15.15 per hour for 2026. Section VIII.B uses 80 percent of monthly full-time earnings. Using the Section VIII example conversion, $15.15 times 40 hours times 52 weeks divided by 12 times 0.80 gives a $2,100.80 reserve.

Parenting time, older children, and direct expenses

The basic obligation increases by 10 percent for qualifying older children, prorated by their number. The uniform parenting-time adjustment applies to that age-adjusted basic amount, not to the add-ons. The combined obligation is shared in proportion to adjusted income, and the payer receives a credit for supported costs paid directly. Final displayed support rounds to the nearest dollar under Section X.A.4. This version supports only whole parenting-day totals below 164 and does not calculate equal-time or reverse-transfer cases.

A worked example

Parent A has $5,000 and Parent B has $3,000 adjusted monthly income. One child has a basic amount of $1,092 at $8,000 combined income. With no older-child adjustment, parenting days, or add-ons, Parent A pays $1,092 times 0.625, which is $682.50, displayed as $683. This is an illustrative hand calculation, not a published official case example.

Reserve and scope limits

If the payer would be left at or below $2,100.80 after the calculated payment, this version returns separate review. It does not automatically choose a reduction or a nominal award because Section VIII requires consideration of the receiving household. Other-family income adjustments, defaults using older guidelines, derivative benefits, education or extraordinary expenses, fractional parenting days, and different schedules are outside scope.

Pending changes

The court review page describes draft revisions open for comment from October 21 through November 21, 2026. Drafts are not applied here. The minimum wage and reserve must be reviewed for January 1, 2027 before use in that year. No future wage or draft table is substituted.

Small awards

Section X.A.5 addresses amounts below the current Support Clearinghouse Fee. The official court fee notice gives an $8 monthly fee effective April 1, 2020. Positive support amounts below $8 return separate review in this version. The fee is not added to the support estimate.
