Arizona has no statutory alimony formula
Arizona has no statutory alimony formula, so this figure uses the AAML national guideline (30% of the payor's gross income minus 20% of the payee's, capped at 40% of combined income) purely as a ballpark. The figure below is an estimate to give you a ballpark — a Arizona judge decides the actual amount and duration using the factors listed beneath the calculator. About this method.

Eligibility: Maintenance is not automatic. The court must first find the requesting spouse qualifies under at least one A.R.S. § 25-319(A) gateway (insufficient property for reasonable needs; unable to be self-sufficient through employment; custodial parent of a child whose age/condition makes outside employment inappropriate; contributed to the other spouse's education/career; or a long-duration marriage at an age precluding self-sufficient employment).
Factors Arizona Courts Weigh
- •Standard of living established during the marriage
- •Duration of the marriage
- •Age, employment history, earning ability, and physical and emotional condition of the spouse seeking maintenance
- •Ability of the paying spouse to meet their own needs while paying maintenance
- •Comparative financial resources of the spouses, including their comparative earning abilities
- •Contribution of the spouse seeking maintenance to the earning ability of the other spouse
- •Extent to which the spouse seeking maintenance reduced their income or career opportunities to benefit the other spouse
- •Ability of both parties to contribute to the future educational costs of mutual children
- •Financial resources of the party seeking maintenance and that spouse's ability to meet their needs independently
- •Time needed to acquire education or training for suitable employment, and whether such training is readily available
- •Excessive or abnormal expenditures, destruction, concealment, or fraudulent disposition of jointly-held property
- •Cost of health insurance for the spouse seeking maintenance and ability to convert coverage
- •Damages and judgments from criminal conduct by one spouse against the other or a child
How Arizona Alimony Works
- •Arizona DOES have official spousal-maintenance guidelines and an official state calculator (revised effective September 1, 2025), but the amount depends on a detailed marriage-length schedule that this tool does not reproduce. Use the official Arizona calculator for a precise figure.
- •Arizona uses the term 'spousal maintenance' (not alimony). Unlike most states, it has a real STATE-published guideline calculator producing a presumptive amount and duration range; courts apply it unless they make written findings that it is inappropriate or unjust.
- •Eligibility is a separate threshold from amount: a spouse must first qualify under one of the five A.R.S. § 25-319(A) gateways before any guideline computation occurs.
- •The 2025 revisions (Administrative Order 2025-101, effective Sept. 1, 2025) raised the high-income-adjustment threshold from $100,000 to $175,000 (and lowered the max adjustment from 80% to 70%), stopped counting monthly mortgage-principal payments as income, and raised the duration cap for 16+ year marriages from 8 years to up to 12 years or 50% of the marriage, whichever is greater.
This is an estimate for educational purposes only, not legal advice. Alimony is highly discretionary; a Arizona judge can order a different amount or duration. Consult a licensed Arizona family-law attorney about your situation. See the official Arizona resource.
How Arizona Calculates Alimony
Arizona addresses spousal support under A.R.S. § 25-319. It uses a guideline equation that takes a percentage of the payor's gross income and subtracts a percentage of the payee's gross income, with statutory caps. The calculator above applies that equation to your figures and shows each step.
Unlike child support, alimony is one of the most discretionary areas of family law. Even in states with a guideline equation, the figure is a starting point a judge can adjust after weighing the statutory factors, the length of the marriage, and each spouse's needs and ability to pay. Treat any number here as an informed estimate, not a guaranteed award.

How Long Alimony Lasts in Arizona
The 2025 guidelines suggest a duration RANGE in months by marriage length: 3-12 months for marriages under 2 years; 6-36 months for 2 to under 5 years; 6-48 months for 5 to under 10 years; 12-60 months for 10 to under 16 years; and for 16+ years, 12 months up to 12 years or 50% of the marriage length, whichever is greater. Longer or indefinite support applies under the 'Rule of 65' (recipient over 42, married 16+ years, age + years married >= 65) and where the marriage lasted 20+ years and the recipient is 50 or older.
What Counts as Income
Arizona's calculation uses each spouse’s gross income — earnings before taxes, including wages, bonuses, commissions, self-employment income, and many recurring sources. Courts can also impute income to a spouse who is voluntarily unemployed or underemployed, meaning support can be based on what a spouse could earn rather than what they currently do. Use your most recent pay stubs and tax return for the most accurate estimate.
Eligibility & Modifying an Order
Maintenance is not automatic. The court must first find the requesting spouse qualifies under at least one A.R.S. § 25-319(A) gateway (insufficient property for reasonable needs; unable to be self-sufficient through employment; custodial parent of a child whose age/condition makes outside employment inappropriate; contributed to the other spouse's education/career; or a long-duration marriage at an age precluding self-sufficient employment).
Alimony orders can usually be modified when there is a substantial change in circumstances — for example, a significant change in either spouse's income, the recipient's remarriage or cohabitation, retirement, or the payor's loss of employment. The specific rules and any non-modifiable agreements depend on your court order and Arizona law.
Frequently Asked Questions
Is this Arizona alimony calculator accurate?
It applies the Arizona guideline from A.R.S. § 25-319 to the numbers you enter, so it gives a close estimate of a typical guideline award. It is not an official court calculation — a judge can order a different amount after weighing the statutory factors.
Is alimony taxable in Arizona?
For divorces finalized after December 31, 2018, alimony is not deductible by the payor and is not taxable income to the recipient under federal law. Most states follow the federal treatment, but check Arizona's current rules for state income tax.
Does cheating affect alimony in Arizona?
It depends on the state. Some states let courts consider marital misconduct among the alimony factors, while others bar it entirely. Review A.R.S. § 25-319 and speak with a Arizona attorney about how fault is treated where you live.
Can alimony be changed later?
Usually yes. Alimony can often be modified when there is a substantial change in circumstances — such as a large change in income, the recipient's remarriage or cohabitation, or the payor's retirement — unless your order or agreement makes it non-modifiable.
Disclaimer
This calculator provides estimates for educational purposes only and is not legal advice. Alimony is highly fact-specific and discretionary; the amount and duration a Arizona court actually orders may differ significantly from any estimate here. For advice about your situation, consult a licensed Arizona family-law attorney.
