Calculate Nevada Alimony Estimate

Estimate potential monthly spousal support and duration using the unofficial Tonopah Formula. The calculation considers the spouses’ gross monthly incomes, child support paid, length of marriage, age, education, and disability status.

Nevada does not have a mandatory alimony formula. Courts determine spousal support under NRS 125.150 after reviewing the financial and personal circumstances of the marriage. This calculator provides an educational estimate only and is not legal advice or a prediction of what a judge will order.

How the Estimate Works

The Tonopah Formula Is an Informal Guideline, Not Nevada Law

The gross-income version of the Tonopah Formula multiplies the monthly income difference by a cumulative percentage derived from the length of the marriage, the lower-earning spouse’s age, education, and disability status. The cumulative percentage is capped at 50 percent. The formula separately produces a suggested duration.

Nevada courts retain discretion to award support that appears just and equitable after considering the statutory factors in NRS 125.150. Property division, financial need, earning capacity, health, marital standard of living, homemaker contributions, and other evidence can materially change the result.
