Utah has no statutory alimony formula
Utah has no statutory alimony formula, so this figure uses the AAML national guideline (30% of the payor's gross income minus 20% of the payee's, capped at 40% of combined income) purely as a ballpark. The figure below is an estimate to give you a ballpark — a Utah judge decides the actual amount and duration using the factors listed beneath the calculator. About this method.

Eligibility: No minimum marriage length to qualify. However, alimony duration is statutorily capped at the length of the marriage (Utah Code 81-4-502(7)(a)), so the marriage length effectively limits the term, not eligibility.
Factors Utah Courts Weigh
- •The standard of living existing during the marriage, including income and the approximate value of real and personal property
- •The financial condition and needs of the payee (who may itemize expenses present during the marriage rather than post-petition expenses)
- •The payee's earning capacity or ability to produce income, including diminished workplace experience from primarily caring for the payor's minor child
- •The ability of the payor to provide support
- •The tax consequences of alimony on each party
- •The length of the marriage
- •Whether the payee has custody of a minor child requiring support
- •Whether the payee worked in a business owned or operated by the payor
- •Whether the payee directly contributed to an increase in the payor's earning power by paying for or enabling the payor's education during the marriage
- •The fault of the parties in causing the breakup of the marriage (adultery, abuse, threats, or undermining the other's financial stability)
How Utah Alimony Works
- •Utah has NO formula or percentage for the alimony amount. The court applies a needs-based analysis: payee's reasonable need (set by the marital standard of living) minus payee's own income/earning capacity equals the shortfall, capped by the payor's ability to pay. This is judicial discretion, not arithmetic.
- •Duration is statutorily capped at the length of the marriage (81-4-502(7)(a)). Temporary alimony already paid counts against this cap, and the cap can be exceeded only for extenuating circumstances or good cause.
- •Standard-of-living equalization is permitted and is a REBUTTABLE PRESUMPTION for marriages of 10+ years where the payee reduced workplace experience by agreement to care for the payor's minor child (81-4-502(4)); this only applies to divorce petitions filed on or after May 1, 2024.
- •Fault matters: adultery, physical abuse, threats of life-threatening harm, or substantially undermining the other spouse's financial stability can affect whether and how much alimony is awarded (81-4-502(2)).
- •Alimony automatically terminates on the payee's remarriage or death, and must be terminated if the payee cohabits with another person (81-4-505). The 2024 Domestic Relations Recodification moved these provisions from former Utah Code 30-3-5 to Title 81, Chapter 4, Part 5, effective September 1, 2024; further amendments took effect via Chapter 249, 2026 General Session (e.g., the aggregate-of-two-marriages rule for remarried-each-other couples filing on or after January 1, 2026).
This is an estimate for educational purposes only, not legal advice. Alimony is highly discretionary; a Utah judge can order a different amount or duration. Consult a licensed Utah family-law attorney about your situation. See the official Utah resource.
How Utah Calculates Alimony
Utah addresses spousal support under Utah Code § 81-4-502. It uses a guideline equation that takes a percentage of the payor's gross income and subtracts a percentage of the payee's gross income, with statutory caps. The calculator above applies that equation to your figures and shows each step.
Unlike child support, alimony is one of the most discretionary areas of family law. Even in states with a guideline equation, the figure is a starting point a judge can adjust after weighing the statutory factors, the length of the marriage, and each spouse's needs and ability to pay. Treat any number here as an informed estimate, not a guaranteed award.
Key Rules in Utah

How Long Alimony Lasts in Utah
Utah Code 81-4-502(7)(a) bars a court from ordering alimony for a period longer than the length of the marriage (years from legal marriage to the filing of the divorce petition). The maximum award duration equals the marriage length; courts often order less. Any temporary (pendente-lite) alimony paid during the divorce counts toward and reduces this cap (81-4-502(7)(b)). A court may exceed the cap only on a finding of extenuating circumstances or good cause (81-4-502(7)(c)). For petitions filed on or after January 1, 2026, where parties married, divorced, and remarried each other, the court aggregates both marriages' durations when applying the cap (81-4-502(8)). Because the cap is years-married, model the duration multiplier as 1.0 of marriage length (an upper bound, not a fixed term).
What Counts as Income
Utah's calculation uses each spouse’s gross income — earnings before taxes, including wages, bonuses, commissions, self-employment income, and many recurring sources. Courts can also impute income to a spouse who is voluntarily unemployed or underemployed, meaning support can be based on what a spouse could earn rather than what they currently do. Use your most recent pay stubs and tax return for the most accurate estimate.
Eligibility & Modifying an Order
No minimum marriage length to qualify. However, alimony duration is statutorily capped at the length of the marriage (Utah Code 81-4-502(7)(a)), so the marriage length effectively limits the term, not eligibility.
Alimony orders can usually be modified when there is a substantial change in circumstances — for example, a significant change in either spouse's income, the recipient's remarriage or cohabitation, retirement, or the payor's loss of employment. The specific rules and any non-modifiable agreements depend on your court order and Utah law.
Frequently Asked Questions
Is this Utah alimony calculator accurate?
It applies the Utah guideline from Utah Code § 81-4-502 to the numbers you enter, so it gives a close estimate of a typical guideline award. It is not an official court calculation — a judge can order a different amount after weighing the statutory factors.
Is alimony taxable in Utah?
For divorces finalized after December 31, 2018, alimony is not deductible by the payor and is not taxable income to the recipient under federal law. Most states follow the federal treatment, but check Utah's current rules for state income tax.
Does cheating affect alimony in Utah?
It depends on the state. Some states let courts consider marital misconduct among the alimony factors, while others bar it entirely. Review Utah Code § 81-4-502 and speak with a Utah attorney about how fault is treated where you live.
Can alimony be changed later?
Usually yes. Alimony can often be modified when there is a substantial change in circumstances — such as a large change in income, the recipient's remarriage or cohabitation, or the payor's retirement — unless your order or agreement makes it non-modifiable.
Disclaimer
This calculator provides estimates for educational purposes only and is not legal advice. Alimony is highly fact-specific and discretionary; the amount and duration a Utah court actually orders may differ significantly from any estimate here.
