Estimate a monthly spousal support range and how long it could last under Utah Code § 81-4-502. Child support is taken out first, the way Utah courts handle it. Nothing you enter is saved or sent anywhere.
With both checked and a marriage of 10+ years, equalizing income is the presumed approach.

Utah has no fixed formula. Under Utah Code § 81-4-502, the court looks at the recipient's financial needs and ability to earn, the payor's ability to pay while meeting their own needs, the length of the marriage, whether the recipient has custody of minor children, the standard of living during the marriage, and the ages, health and retirement prospects of both people.
The goals are to keep the recipient close to the standard of living from the marriage, to equalize the two households where that's fair, and to keep the recipient from needing public assistance.
Alimony can't last longer than the marriage did, unless there are extenuating circumstances. Temporary alimony paid while the divorce was pending counts toward that limit. Alimony ends if either person dies or the recipient remarries, and the court can end it if the recipient lives with a new partner.
This calculator shows a range from half the length of the marriage up to the full length, and uses the midpoint for the totals.
Child support is set under Utah's guidelines before alimony is considered. The paying parent's child support comes out of their income, so it isn't counted again as money available for alimony. Leave child support out of the expense figures above so it's only counted once.
The range comes from three approaches: equalizing what each person has left after expenses, a benchmark based on the difference in incomes (a negotiation reference, not Utah law), and the gap between the recipient's income and the standard of living during the marriage.
