Estimation only — Utah Code § 81-4-502. Utah alimony has no statutory formula. Judges apply 8 factors (*Jones v. Jones*, 1985) with broad discretion. This calculator models the needs/ability test and all statutory factors but results are a range, not a guarantee. Consult a mediator or attorney for your specific situation.

Step 1 — Monthly gross income

Before taxes, all sources of income

Step 2 — Employment status & marriage

Courts may impute earning-capacity income if recipient is voluntarily not working (§ 81-4-503). HB 220 (2024) protects stay-at-home caregivers from full imputation.

Step 3 — Monthly expenses (Financial Declaration)
Utah courts require a Financial Declaration (Utah Rule 26.1) documenting all income and monthly expenses. Entering actual figures here produces a more accurate range and prepares you for that form. Leave blank to use estimates.

Krajeski v. Krajeski (2025): Courts reversed a $12,751/mo award because expense figures weren't credibly documented. Inflated expenses destroy credibility. Base these on actual historical spending, backed by bank and credit card statements.

Step 4 — Recipient's circumstances

Total years away from paid employment

Step 5 — Fault & additional factors

Utah courts may consider fault under § 81-4-502(d)(viii). Post-Gardner v. Gardner (2019 UT 61): fault must "substantially contribute" to the breakup — not be the only cause. Courts have broad discretion to reduce amount, shorten duration, or deny alimony entirely. Fault cannot be used as punishment and cannot inflate an award above demonstrated need.

How Utah calculates alimony

Utah has no alimony formula. Instead of plugging numbers into an equation, a judge works through a needs-and-ability analysis: first the receiving spouse's reasonable monthly needs, then that spouse's own ability to meet those needs, and finally the other spouse's ability to pay. Alimony fills the gap that remains — capped by what the paying spouse can actually afford. Because so much is left to the judge's discretion, two similar households can end up with very different awards, which is why this calculator gives a range rather than a single figure.

The factors a Utah judge weighs

  • The financial condition and needs of the receiving spouse
  • That spouse's earning capacity or ability to produce income
  • The paying spouse's ability to provide support
  • The length of the marriage
  • Whether the receiving spouse has custody of minor children requiring support
  • Whether the receiving spouse worked in a business owned or operated by the paying spouse
  • Whether the receiving spouse directly contributed to the other's increased skill or education
  • Fault of a spouse that substantially contributed to the breakup of the marriage

How long alimony lasts

As a general rule, alimony in Utah cannot last longer than the number of years the marriage lasted, unless the court finds extenuating circumstances. Courts generally try to help the receiving spouse become self-supporting, so a short marriage often means little or no alimony, while a long marriage can support a longer award.

When alimony can change or end

Alimony ends automatically when the receiving spouse remarries and terminates if that spouse cohabits with a new partner; it also ends on the death of either former spouse. Short of that, either spouse can ask the court to modify alimony when there is a substantial, material change in circumstances — such as a job loss or a major income change — that wasn't foreseeable when the decree was signed.

Frequently asked questions

Is there an alimony formula in Utah?

No. Unlike child support, Utah has no fixed alimony formula. A judge applies a needs-and-ability analysis — the recipient's reasonable monthly needs, their ability to meet those needs, and the paying spouse's ability to pay — with wide discretion. That's why this calculator returns a low/mid/high range instead of a single number.

How long does alimony last in Utah?

As a general rule, alimony cannot last longer than the number of years the marriage lasted, unless the court finds extenuating circumstances. Courts generally aim to help the receiving spouse become self-supporting, so shorter marriages usually mean shorter — or no — alimony.

Does adultery or fault affect alimony?

It can. Fault during the marriage — including conduct that substantially contributed to the breakup — is one of the factors a Utah court may weigh when deciding alimony, though it is rarely decisive on its own.

Can alimony be changed after the divorce?

Yes. Either spouse can ask the court to modify alimony if there is a substantial, material change in circumstances that was not foreseeable when the decree was entered — for example, a job loss or a significant change in income.

Does alimony end if my ex remarries or moves in with someone?

Alimony ends automatically when the receiving spouse remarries, and it terminates if that spouse cohabits with a new partner. It also ends on the death of either former spouse.

Is alimony taxable in Utah?

For divorces finalized after 2018, federal law (the Tax Cuts and Jobs Act) means alimony is not deductible by the paying spouse and not counted as taxable income to the recipient. See our divorce and taxes guide for details — this is not tax advice.
