Alaska Alimony Calculator (2026)

Alaska’s courts apply AS 25.24.160(a)(2) – a list of factors rather than a fixed formula – and traditionally favor property division over long‑term spousal support. Most judges award rehabilitative or reorientation alimony, and the numbers below are only a rule‑of‑thumb estimate, not a legal requirement.

Alaska has no statutory alimony formula. Courts decide case by case under AS 25.24.160(a)(2). The calculator below shows a widely used rule of thumb (the AAML guideline) as a negotiation starting point — it is not the law and a judge may land anywhere the factors justify.

The law behind this calculator: Alaska spousal support factors — AS 25.24.160(a)(2).

How Alaska calculates it

  • Identify the higher‑earning spouse’s annual gross income and calculate 30% of that amount.
  • Identify the lower‑earning spouse’s annual gross income and calculate 20% of that amount.
  • Subtract the lower‑earner’s 20% figure from the higher‑earner’s 30% figure.
  • Apply the 40% combined‑income cap so the recipient’s total income does not exceed 40% of the couple’s combined earnings.
  • Determine the support duration by marriage length: under 3 years = 30%, 3–10 years = 50%, 10–20 years = 75%, over 20 years = indefinite.

Worked example

In the example, the higher earner makes $100,000 per year and the lower earner $40,000 per year in a 12‑year marriage. Thirty percent of $100,000 is $30,000; twenty percent of $40,000 is $8,000; the difference is $22,000 per year, which the 40% cap reduces to $16,000 per year, or about $1,333 per month as a rule‑of‑thumb starting point. For a 12‑year marriage the duration guide falls in the 10–20‑year band, so 75% of 144 months yields roughly 108 months of support. The court is not bound by these figures.

Frequently asked questions

How does Alaska estimate alimony amounts?

Alaska has no statutory alimony formula. Courts look at the factors in AS 25.24.160(a)(2) and often use the guideline of 30% of the higher earner’s gross income minus 20% of the lower earner’s gross income, then apply a 40% combined‑income cap.

What duration can I expect for alimony in Alaska?

A common rule‑of‑thumb ties duration to marriage length: 30% of the marriage term for unions under 3 years, 50% for 3–10 years, 75% for 10–20 years, and indefinite support for marriages longer than 20 years. The court ultimately decides.

Is alimony taxable in Alaska?

Alaska does not have a state income tax, so alimony is not taxed at the state level. For federal purposes, alimony received is generally taxable income to the recipient and deductible by the payor, unless a post‑2018 divorce agreement states otherwise.

What factors do Alaska courts consider when awarding alimony?

Courts weigh the statutory factors in AS 25.24.160(a)(2), including each party’s earning capacity, age, health, standard of living during the marriage, duration of the marriage, and any rehabilitative needs such as education or job training.

Have Alaska’s alimony guidelines changed recently?

Alaska has not adopted a statutory alimony formula, and the guideline percentages (30%/20% and the 40% cap) are based on professional practice rather than legislative amendment. Recent case law continues to emphasize short‑term, rehabilitative support over long‑term maintenance.

Is the calculation different in Anchorage, Fairbanks or Juneau?

No. AS 25.24.160(a)(2) applies statewide, so courts in Anchorage, Fairbanks, Juneau and every other county start from the same guideline. Local practice can differ in how judges weigh deviation factors and in typical negotiated outcomes, but the formula on this page is the one used across Alaska.
