📌 Quick Answer: Arizona uses Supreme Court guidelines (effective Sept 2025) to estimate spousal maintenance. For a 10-year marriage (120 months) with a $6,000 monthly income gap, the guideline range is roughly $600–$1,500/month for 12–60 months. The court must apply the guideline result unless written findings justify deviation [citation:4][citation:6].

How Arizona Calculates Spousal Maintenance in 2026
Arizona is one of the few states with a formulaic approach to spousal maintenance. The Arizona Supreme Court adopted official guidelines and a standardized calculator effective September 24, 2022, with major updates effective September 1, 2025 [citation:4][citation:6].
The process has two steps. First, the court must find the requesting spouse eligible under A.R.S. § 25-319(A) — for example, lacking sufficient property, unable to be self-sufficient, caring for a young child, contributing to the other spouse's career, or a long marriage combined with age [citation:8]. Only after eligibility is established does the calculator determine the amount and duration [citation:5].
The calculator uses both spouses' gross incomes, family size, and marriage length to produce a monthly amount range and a duration range. The court must apply the guideline result unless it makes written findings that doing so would be "inappropriate or unjust" [citation:4].
Key 2025 Guideline Changes for 2026 Cases
The September 2025 revisions brought significant updates [citation:6]:
High-income threshold: Raised from $100,000 to $175,000. The maximum high-income adjustment was reduced to 70%.
Mortgage principal removed: No longer counted as a living expense, preventing double-counting when the home is divided.
Overtime income: Averaged over the three years before filing, not just the most recent year.
Retirement asset attribution: Income cannot be attributed if withdrawing funds would trigger an early-withdrawal penalty; Social Security cannot be attributed before full retirement age.
Long marriage duration: Marriages of 192+ months not subject to Rule of 65 may qualify for 12–144 months or 50% of marriage length, whichever is greater.
What Is the Rule of 65?
The Rule of 65 is Arizona's exception for older spouses in long marriages. It applies when the requesting spouse's age plus the length of the marriage (in years) equals 65 or more [citation:6].
For example, a 55-year-old spouse married for 12 years would meet the threshold (55 + 12 = 67). When the Rule of 65 applies, the court may extend maintenance beyond the standard duration brackets, potentially up to an indefinite award in appropriate cases [citation:13].
Why the Arizona Calculator Is Only a Starting Point
This calculator provides a simplified estimate based on the guideline framework. The official Arizona Spousal Maintenance Calculator — available through Maricopa and Pima County Superior Courts — uses detailed expenditure tables from the Bureau of Labor Statistics and accounts for factors this simplified tool does not [citation:1][citation:6].
Additionally, the court can deviate from the guideline amount if applying it would be unjust, based on factors like abnormal expenditures, marital waste, or unusual financial circumstances. However, the court must make written findings to do so [citation:9].

💡 Expert Tips for Arizona Spousal Maintenance
Tip #1: Eligibility comes first. If you don't meet one of the five A.R.S. § 25-319(A) factors, the calculator never applies [citation:8].
Tip #2: Document overtime history. The 2025 update requires averaging the 3 years before filing, not just the last year [citation:6].
Tip #3: Check the Rule of 65. If age + marriage years ≥ 65, duration can extend significantly [citation:6].
Tip #4: Use the official AZ calculator for accuracy. This simplified tool is a starting point, not a substitute [citation:1].
Tip #5: Marital misconduct doesn't affect the amount, but "marital waste" (excessive spending on affairs, gambling) can be a deviation factor [citation:9].
