Wyoming Alimony Calculator (2026)

Wyo. Stat. § 20‑2‑114 makes clear that Wyoming courts have no statutory alimony formula and generally prefer to equalize property rather than award spousal support. Any alimony order must be "reasonable" and is left to the judge’s discretion. The figures below are a widely‑used rule‑of‑thumb from the American Academy of Matrimonial Lawyers, offered only as an estimate—not legal authority—in Wyoming’s alimony landscape.

Wyoming has no statutory alimony formula. Courts decide case by case under Wyo. Stat. § 20-2-114. 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: Wyoming alimony — Wyo. Stat. § 20-2-114.

How Wyoming calculates it

  • Calculate 30% of the higher‑earning spouse’s gross annual income.
  • Calculate 20% of the lower‑earning spouse’s gross annual income.
  • Subtract the lower‑earner amount from the higher‑earner amount to get a preliminary yearly support figure.
  • Apply a cap so the recipient’s total income does not exceed 40% of the combined income of both spouses.
  • Determine a duration guide: 30% of the marriage length if under 3 years, 50% for marriages of 3–10 years, 75% for 10–20 years, and indefinite for marriages over 20 years.

Worked example

In the example, the higher earner makes $100,000 per year and the lower earner makes $40,000 per year over a 12‑year marriage. Applying the rule‑of‑thumb, 30% of $100,000 equals $30,000 and 20% of $40,000 equals $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 starting point. For a 12‑year marriage, the duration guide (10–20 years bracket) suggests 75% of 144 months, roughly 108 months, though the court is not bound by these figures.

Frequently asked questions

How does Wyoming decide if a spouse is eligible for alimony?

Eligibility is judged case‑by‑case under Wyo. Stat. § 20‑2‑114, which requires the award to be reasonable and considers factors like each party’s earning capacity, the standard of living during the marriage, and the length of the marriage.

Is alimony taxable in Wyoming?

Wyoming does not have a state income tax, so alimony is not subject to state tax. However, for federal tax purposes, the treatment follows the post‑2025 rules: the payer cannot deduct the payments and the recipient does not include them as income.

How long might alimony last after a 12‑year marriage in Wyoming?

Using the rule‑of‑thumb, a 12‑year marriage falls in the 10–20‑year bracket, so the suggested duration is 75% of the marriage length, which equals roughly 108 months.

Can the amount be reduced if the recipient’s own income is high?

Yes. The rule‑of‑thumb caps the recipient’s total income at 40% of the combined income of both spouses, which can lower the support amount if the recipient’s earnings push them above that threshold.

What recent trends affect alimony awards in Wyoming?

Wyoming courts have increasingly emphasized property division over spousal support, and recent case law stresses that alimony should be limited to addressing genuine financial disparity, not as a punitive measure.

Is the calculation different in Cheyenne, Casper or Laramie?

No. Wyo. Stat. § 20-2-114 applies statewide, so courts in Cheyenne, Casper, Laramie 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 Wyoming.
