How child support is calculated in Utah
Utah adds both parents' adjusted monthly gross incomes, looks up the base combined child support obligation in a statutory table by income and number of children, and divides it between the parents in proportion to their incomes. Separate rules apply for joint physical custody (overnights above 110), low-income parents and extended parent-time.[1]

The rules behind Utah’s numbers
The guideline is Utah Code § 81-6-204. Open each rule to read the exact words.
- Income counted
Combined adjusted average monthly gross income of both parents
Each parent’s average monthly gross income is reduced by previously ordered alimony and child support actually paid, the two are added, and the table is read at that combined figure.[1]
Official text · Utah Code § 81-6-204(1)(c)
“combining the adjusted average monthly gross incomes for both parents; and”
- Top of the guidelines
Table ends at $100,000/month combined; above it, case-by-case but not less than the top amount
If combined income is above the table’s highest level, the court sets a just amount case by case, but not less than the table’s highest amount for that number of children; there is no maximum.[1]
Official text · Utah Code § 81-6-204(8)(a)
“If the combined adjusted gross income exceeds the highest level specified in the base combined child support obligation table, the court shall order an appropriate and just amount of child support on a case-by-case basis, except that the court may not order an amount that is less than the highest level specified in the table for the number of children due child support.”
- Minimum order
$30 minimum in sole physical custody cases
In a sole physical custody case the base child support award may not be less than $30.[1]
Official text · Utah Code § 81-6-205(5)
“A base child support award in a sole physical custody case may not be less than $30.”
- Low income
Low income table (obligor only); lesser of the two results applies
If a parent’s adjusted income is below the top of the low income table, the award is the lesser of the regular income-shares amount and the low income table amount.[1]
Official text · Utah Code § 81-6-205(4)(a)
“If a parent's individual monthly adjusted gross income is less than the highest amount of monthly adjusted gross income shown in the low income table, the court or administrative agency shall determine that the base child support award is the lesser of:”
- Shared parenting time
Joint physical custody: reductions of .0027 per overnight from 111–130 and .0084 per overnight above 130
In joint physical custody, the parent with fewer overnights has their income share reduced by 0.27% of the base obligation for each overnight from 111 to 130 and 0.84% for each overnight above 130.[1]
Official text · Utah Code § 81-6-206(4)
“multiplying the number of overnights over 110 and under 131 for that parent by .0027;”
- Shared parenting time
Extended parent-time: 50% reduction (25 of 30 days) or 25% (12 of 30 days)
The award is cut by 50% for each child during periods the child is with the noncustodial parent at least 25 of any 30 consecutive days, or by 25% for at least 12 of any 30 consecutive days.[1]
Official text · Utah Code § 81-6-211(1)(a)
“reduced by 50% for each child for time periods during which the child is with the noncustodial parent by order of the court or by written agreement of the parties for at least 25 of any 30 consecutive days of extended parent-time; or”
