How to Use the Utah Child Support Calculator
Enter what you know and press Calculate Estimate. The calculator follows the child support guidelines in Utah Code Title 81, Chapter 6.
- Enter each parent's gross monthly income. Utah uses gross income, not take-home pay.
- Choose the number of children and the parent the children live with most of the time.
- Enter the children's share of the health insurance premium and work-related child care, and say who pays them.
- Enter the overnights a year with the other parent, or tick the equal parent-time box.
Your numbers are sent with the form, not placed in the page address, and this site does not store them. This is a planning estimate. A Utah court or the Office of Recovery Services sets the actual amount.
Utah Child Support Law in 2026
Looking for Utah child support guidelines for 2026? On September 1, 2024 the Utah Child Support Act moved from Title 78B, Chapter 12 to Title 81, Chapter 6 (Chapter 366, 2024 General Session). Old references to 78B-12 now point to sections in 81-6.
- The base combined table in 81-6-304 applies to orders first entered on or after January 1, 2023, and to modifications of older final orders made on or after January 1, 2025.
- The 2026 General Session (Chapter 155) rewrote the child care section. From January 1, 2027, new and modified orders will also include a minimal child care award from the table in 81-6-306, unless the low income table is used.
How Utah Calculates Child Support
- Find each parent's adjusted gross income: gross monthly income (81-6-203) minus alimony and child support previously ordered and paid.
- Add both incomes and find the base combined child support obligation in the table for the total number of children. The amount is for all the children, not per child.
- Multiply it by each parent's percentage of combined income. In sole physical custody the parent without custody pays that share (81-6-205).
- Add the paying parent's half of the children's health insurance premium and work-related child care.
All worksheet figures are rounded to the nearest dollar.
The Utah Base Combined Child Support Table
Sample rows (combined monthly adjusted gross income):
| Combined monthly income | 1 child | 2 children | 3 children |
|---|
| $2,901-$3,000 | $485 | $794 | $918 |
| $4,901-$5,000 | $668 | $1,175 | $1,351 |
| $7,901-$8,000 | $915 | $1,442 | $1,642 |
| $9,901-$10,000 | $1,026 | $1,683 | $1,917 |
| $14,901-$15,000 | $1,340 | $2,155 | $2,452 |
| $28,001-$30,000 | $2,408 | $3,756 | $4,251 |
| $98,001-$100,000 | $5,908 | $8,356 | $9,751 |
The table runs from $1,951 to $100,000 a month: $100 steps up to $20,000 and $2,000 steps above that, for one to six children. Where no amount is listed, the base obligation is $0 and the low income table is used. Above $100,000 the court sets an appropriate amount, but not less than the top of the table.
Low Income Table and Minimum Support
The low income table (81-6-305) uses only the paying parent's own income. If that income is in the table, support in a sole custody case is the lesser of the income-share amount and the low income table amount. The lowest amount is $30 a month, which is also the minimum award in a sole physical custody case.
Joint Physical Custody and Parent-Time
Joint physical custody means the child stays overnight with each parent for more than 30% of the year and both parents contribute to the child's expenses (Utah Code 81-9-101). Then 81-6-206 applies:
- Find the share of the base obligation of the parent with fewer overnights.
- Subtract .0027 x the base obligation for each overnight from 111 to 130.
- Subtract .0084 x the base obligation for each overnight over 130.
- If the result is above $0, that parent pays it; if it is below $0, the other parent pays the difference.
With an equal parent-time schedule, the parent with the lower income is counted as having 183 overnights. Separately, in sole custody cases, extended parent-time of at least 12 of 30 consecutive days reduces support for that period by 25%, and at least 25 of 30 days by 50% (81-6-211).
Utah Child Support Examples
In each example Parent B has the children most of the time. Amounts are monthly and come from this calculator.
Example 1: One child
A earns $5,000 and B earns $3,000 ($8,000 combined). The table gives $915, and A's 62.5% share is $572 a month.
Example 2: Two children with insurance and child care
A earns $6,000 and B earns $4,000. The table gives $1,683 and A's 60% share is $1,010. B pays $200 insurance and $600 child care, and A adds half of each ($100 + $300): $1,410 a month.
Example 3: Equal parent-time
A earns $7,000 and B earns $5,000, two children. The base is $1,892 and A's share is $1,104. A has 182 overnights, so $928 is subtracted: $176 a month.
Example 4: Low income
A earns $1,500 and B earns $5,000, two children. A's income share is $311, but the low income table shows $209 at A's income: $209 a month.
Example 5: 146 overnights
A earns $6,000 and B earns $3,000, one child, 146 overnights with A. A's $647 share minus $183 for overnights over 110: $464 a month.
