Arizona's Spousal Maintenance Guidelines, adopted by the Supreme Court under A.R.S. § 25-319(B) and in their 2025 edition since September 1, 2025, give a duration range the court cannot leave: 3 to 12 months after a marriage under 24 months, 6 to 36 under 60, 6 to 48 under 120, 12 to 60 under 192, and from 192 months 12 months up to 144 months or 50% of the marriage, whichever is greater. Marriage length runs to the service of the divorce petition. The amount is different: the guidelines build it from household spending data in the court's Spousal Maintenance Calculator, with a high-income adjustment from $175,000 a year, so no percentage reproduces it. Our calculator shows the duration range only and sends you to the official calculator for the amount. Eligibility under § 25-319(A) comes first.
Estimated spousal support in Arizona, per month
$0
Duration: 12 months to 5 years
| Months of marriage (to service of the petition) | $144 |
| Duration range | 12 to 60 months |
Arizona sets the amount with the Supreme Court's Spousal Maintenance Calculator (https://www.azcourts.gov/familylaw/Child-Support-Family-Law-Information/Spousal-Maintenance-Guidelines), which uses household spending data rather than a percentage, so no amount is computed here.
Courts may deviate from the amount range but not from the duration ranges.
Estimate under the Arizona formula as published; eligibility, the judge's findings and an agreement between spouses decide the real order. How this is calculated.
Why we show no amount
Arizona is the only state on this site whose official guideline cannot be written as a percentage. The court's calculator takes family size (up to 5 people), both spouses' actual and attributed income, then looks up what a household of that size and income spends according to the Bureau of Labor Statistics Consumer Expenditure Survey. The receiving spouse's share of that spending, in proportion to income, is subtracted, and what remains is the amount range. For high incomes the spending figure rises by 1% for every $2,500 of family income above $175,000, up to 70%. Under $44,000 of combined income the range starts at zero. The spending tables are inside the Supreme Court’s calculator, not in the guideline text, so any number we printed would be a guess.
The ranges, applied
An 8-year marriage gives 6 to 48 months. Seventeen years gives 12 to 144 months, because 50% of 204 months is below 144. Twenty-five years gives 12 to 150 months, the half-marriage figure now being the larger. The judge picks a point inside the range from the statutory factors and may not go outside it, though the amount itself can be adjusted for listed deviation reasons.
The Rule of 65 and other exits
Three situations take the term out of the table. Under the Rule of 65, a requesting spouse aged at least 42, after a marriage of at least 192 months, whose age plus years of marriage reaches 65, gets a duration set case by case. A permanent disability that will never allow self-sufficiency is handled the same way, while an uncertain disability gets a fixed term the recipient can later ask to extend. Extraordinary circumstances proven by clear and convincing evidence, such as caring for a child who prevents work or a catastrophic illness, also lead to a case-by-case term. There are no lifetime awards; marital misconduct plays no part (§ 25-319(C)).
The Arizona rule this calculator applies
Scope. Arizona Spousal Maintenance Guidelines adopted by the Supreme Court under A.R.S. § 25-319(B); current edition effective 09/01/2025 (AO 2025-101), previous 2023 edition effective July 10, 2023. Apply to petitions filed on or after September 24, 2022; also to temporary orders (Section VI).
Amount. No percentage formula. After eligibility under § 25-319(A), the court uses the official Spousal Maintenance Calculator: (1) family size (max 5); (2) combined Spousal Maintenance Income (actual + attributed income of both spouses); (3) the calculator generates combined expenditures from BLS Consumer Expenditure Survey data (per capita method) and the receiving spouse's share proportional to income; (4) amount range = combined expenditures minus the receiving spouse's share. High-income adjustment: +1% for every $2,500 of intact family income from $175,000 a year, up to +70%. Combined income at or below 80% of the state minimum wage gives zero; above that but under $44,000 the range starts at zero. A 4% rate of return may be attributed to income-producing property.
Duration. Guidelines Section IV(B)(2): marriage length = months from marriage to service of the petition. Standard duration ranges: < 24 months: 3 to 12 months; 24 to < 60: 6 to 36 months; 60 to < 120: 6 to 48 months; 120 to < 192: 12 to 60 months; 192 or more (not under the Rule of 65): 12 months up to 144 months or 50% of the marriage length, whichever is greater. Rule of 65: if the requesting spouse is at least 42, the marriage is at least 192 months, and age + marriage years >= 65, duration is discretionary. Courts cannot deviate from the duration ranges.
Eligibility. A.R.S. § 25-319(A): the spouse seeking maintenance lacks sufficient property for reasonable needs, lacks earning ability adequate to be self-sufficient, is the parent of a child whose age or condition prevents outside work, made a significant contribution to the other spouse's education or career or reduced own career, or had a long marriage and is of an age that may preclude adequate employment. Maintenance is ordered without regard to marital misconduct (§ 25-319(C)).
Worth knowing in Arizona
- Arizona's maintenance amount comes from household expenditure data (BLS Consumer Expenditure Survey), not from a percentage of income. source
- There are no lifetime awards under the Guidelines; indefinite awards shift the burden of modification to the paying spouse. source
- Courts may deviate from the amount range but not from the duration ranges (Guidelines Section I). source
- Marriage length is counted only to the date the dissolution petition is served; cohabitation before the wedding is excluded. source
