Nevada Alimony Calculator (2026)

Nevada’s NRS 125.150 makes clear that the state has no statutory alimony formula—the older “Tonopah formula” is not law—so courts weigh eleven statutory factors and may order rehabilitative support for education or training. This estimate uses the widely cited American Academy of Matrimonial Lawyers rule of thumb and is only a starting point, not a legal determination.

Nevada has no statutory alimony formula. Courts decide case by case under NRS 125.150. 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.

How Nevada calculates it

  • Take 30% of the higher‑earning spouse’s gross annual income.
  • Take 20% of the lower‑earning spouse’s gross annual income.
  • Subtract the lower‑earner amount from the higher‑earner amount.
  • Apply a cap so the recipient’s total income does not exceed 40% of the combined income.
  • For duration, use 30% of the marriage length if under 3 years, 50% if 3–10 years, 75% if 10–20 years, and treat it as indefinite if over 20 years.

Worked example

Higher earner $100,000/year, lower earner $40,000/year, 12-year marriage: 30% × $100,000 = $30,000; 20% × $40,000 = $8,000; difference $22,000/year, reduced to $16,000 by the 40% cap ≈ $1,333/month as a rule-of-thumb starting point. Duration guide for 12 years (10–20 years): 75% of 144 months ≈ 108 months. The court is not bound by any of this.

Frequently asked questions

How does Nevada calculate alimony without a statutory formula?

Nevada courts apply the eleven factors listed in NRS 125.150 and often use the AAML rule of thumb—30% of the higher earner’s income minus 20% of the lower earner’s, subject to a 40% combined‑income cap—to arrive at an estimate.

Is alimony taxable in Nevada?

Nevada does not have a state income tax, so alimony is not taxed at the state level. Federal tax treatment follows the IRS rules in effect at the time of the award.

Can I receive alimony for going back to school in Nevada?

Yes. Nevada courts may award rehabilitative alimony to help a spouse obtain education or training that improves future earning potential, as one of the statutory factors.

How long does alimony typically last in Nevada?

Duration is guided by the marriage length: 30% of the term for marriages under 3 years, 50% for 3–10 years, 75% for 10–20 years, and may be indefinite for marriages longer than 20 years, though the court has discretion.

What recent changes affect Nevada alimony awards?

The key change is that Nevada still has no codified formula; courts continue to rely on the eleven NRS 125.150 factors and the AAML rule of thumb, while the older Tonopah formula remains non‑binding.

Is the calculation different in Las Vegas, Henderson or Reno?

No. NRS 125.150 applies statewide, so courts in Las Vegas, Henderson, Reno 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 Nevada.
