Arizona Alimony Calculator (2026)

Arizona adopted formal Spousal Maintenance Guidelines in 2023, complete with an official calculator that produces a range of amounts and durations based on income and marriage length. Courts normally apply those guidelines unless they find a justified reason to deviate. The estimate below follows a widely used rule‑of‑thumb—not the official guideline output—so treat it as a rough starting point, not a legal determination.

Arizona no tiene una fórmula legal de pensión conyugal. Los tribunales deciden caso por caso bajo A.R.S. § 25-319 and the 2023 Spousal Maintenance Guidelines. La calculadora muestra una regla práctica muy usada (la guía AAML) como punto de partida para negociar — no es la ley y un juez puede fijar cualquier monto que los factores justifiquen.

La ley detrás de esta calculadora: Arizona spousal maintenance — A.R.S. § 25-319 and the 2023 Spousal Maintenance Guidelines.

Cómo lo calcula Arizona

  • There is no statutory alimony formula in Arizona; the court decides case‑by‑case using the factors listed in A.R.S. § 25‑319.
  • The rule‑of‑thumb starts with 30% of the higher‑earning spouse’s gross annual income.
  • Subtract 20% of the lower‑earning spouse’s gross annual income from that amount.
  • If the resulting support would cause the recipient’s total income to exceed 40% of the combined income, reduce the support so the cap is met.
  • Determine duration by marriage length: 30% of months if under 3 years, 50% if 3–10 years, 75% if 10–20 years, and indefinite if over 20 years.

Ejemplo resuelto

In the worked example, the higher earner makes $100,000 per year and the lower earner makes $40,000 per year, with a 12‑year marriage. The rule‑of‑thumb calculation is 30% × $100,000 = $30,000; 20% × $40,000 = $8,000; the difference is $22,000 per year, which is reduced to $16,000 by the 40% cap, yielding roughly $1,333 per month as a starting point. For a 12‑year marriage (which falls in the 10–20‑year bracket), the duration guide is 75% of 144 months, or about 108 months. The court is not bound by any of this.

Preguntas frecuentes

How long can I expect spousal maintenance if my marriage lasted 5 years?

For a marriage between 3 and 10 years, the rule‑of‑thumb suggests a duration equal to 50% of the marriage’s total months, though an Arizona court may order a shorter or longer period if justified.

Is spousal maintenance taxable in Arizona?

Arizona follows federal treatment: the recipient must include maintenance in taxable income, and the paying spouse may deduct it on the federal return, subject to the 2018 tax law changes.

What formula does the 2023 Arizona guideline use to calculate maintenance?

The guideline applies a rule‑of‑thumb: 30% of the higher earner’s gross income minus 20% of the lower earner’s gross income, then caps the recipient’s total income at 40% of the combined income.

Can an Arizona court order a maintenance period that’s longer than the guideline suggests?

Yes. While the guidelines provide a default duration range, the court can deviate and order a longer or shorter period if the statutory factors support such a decision.

What changed in Arizona’s spousal maintenance rules in 2023?

In 2023 Arizona introduced formal Spousal Maintenance Guidelines and an official calculator that generate amount and duration ranges based on the parties’ incomes and marriage length, giving courts a standardized baseline.

¿El cálculo es diferente en Phoenix, Tucson o Mesa?

No. A.R.S. § 25-319 and the 2023 Spousal Maintenance Guidelines rige en todo el estado, así que los tribunales de Phoenix, Tucson, Mesa y de cualquier otro condado parten de la misma guía. La práctica local puede variar en cómo los jueces ponderan los factores, pero la fórmula de esta página es la que se usa en todo Arizona.
