Arizona Spousal Maintenance Calculator

Arizona does not use a fixed formula to calculate spousal maintenance the way it does for child support. There is no online calculator the court endorses, and no statutory table that produces a dollar amount based on income inputs alone. Instead, judges weigh a list of factors under A.R.S. Section 25-319 to decide whether maintenance is appropriate, how much to award, and for how long.

This makes spousal maintenance one of the most unpredictable parts of an Arizona divorce — and one of the most consequential for self-represented filers to understand before they agree to waive it.

Who Qualifies for Spousal Maintenance

Before a judge considers the amount, they must first determine whether the requesting spouse is eligible at all. Under A.R.S. Section 25-319(A), the court will award maintenance only if the requesting spouse meets at least one of these criteria:

• Lacks sufficient property (including their share of community property) to meet their reasonable needs
• Cannot be self-supporting through appropriate employment, or is the custodian of a child whose age or condition makes outside employment impractical
• Contributed to the other spouse's earning capacity (for example, working while the other spouse completed a degree or professional certification)
• Had a marriage of long duration and is of an age that precludes gaining adequate employment

Factors That Determine the Amount and Duration

Once eligibility is established, the judge evaluates factors including:

• The standard of living established during the marriage
• Duration of the marriage (longer marriages tend to produce longer maintenance awards)
• Age, employment history, earning ability, and physical and emotional condition of the requesting spouse
• The ability of the paying spouse to meet their own needs while making payments
• Each spouse's financial resources and earning abilities after property division
• Whether the requesting spouse contributed as a homemaker
• The time needed for education or training to become self-sufficient

In practice, Maricopa County family law attorneys often use informal guidelines: approximately 20 to 25 percent of the income gap between spouses, for a duration of roughly one-third to one-half the length of the marriage. But these are practitioner rules of thumb, not binding law. A judge can award more or less depending on the specific circumstances.

The Summary Consent Decree Waiver Trap

Couples who qualify for Arizona's Summary Consent Decree (the fastest and cheapest filing path) must permanently waive spousal maintenance as a condition of using it. This waiver is non-modifiable — once the decree is signed, neither spouse can come back to court to request maintenance, regardless of future financial changes.

For couples with roughly equal incomes, this is rarely an issue. But for a couple where one spouse earns significantly more than the other, choosing the Summary Consent path to save on filing fees means the lower-earning spouse forfeits what could be thousands of dollars in monthly support — permanently.

How to Prepare Your Maintenance Position

Whether you are requesting maintenance or expect your spouse to request it, organizing your financial data before negotiations begin (or before trial) is critical:

1. Document both spouses' gross monthly incomes from all sources
2. List the monthly expenses that reflect the marital standard of living
3. Calculate the income gap and the requesting spouse's shortfall
4. Estimate the time needed for education or job reentry
5. Review the length of marriage against the factors listed above

The Arizona Divorce Filing Process Guide includes a spousal maintenance evaluation worksheet that walks you through these calculations step by step, so you can present an organized financial picture to the court or use it as a starting point for negotiation.
