Utah sets child support with the income-shares model (Utah Code § 81-6-304): both parents' gross monthly incomes are added together, a base amount for that combined income and number of children is read from the state guideline table, and each parent owes their percentage share. If each parent has at least 111 overnights a year, the joint physical custody worksheet applies instead and the amount is adjusted for the time the child spends in each home (§ 81-6-206(4)(a)). Enter both incomes, the number of children and the overnights below for an estimate.
For estimation purposes only. This calculator uses the official Utah ORS table and guidelines. Actual court orders may vary based on additional factors. Consult an attorney or mediator for your specific situation.
Gross monthly income includes wages, salary, commissions, bonuses, self-employment income, rental income, and regular overtime. Use monthly averages for variable income.
Utah uses the income shares model — both parents' incomes are combined to determine the child's standard of living, then each parent contributes their proportionate share.
Worksheet A applies when one parent has primary custody. Worksheet B (joint custody offset) applies when each parent has 111+ overnights per year. Compare joint vs sole custody in Utah.
This estimate assumes equal sharing of the children’s qualifying health-insurance premiums and work-related childcare costs, separately from base support. The applicable order and statutory requirements control. See Utah Code §§ 81-6-208 and 81-6-209.
Courts can deviate from the guideline amount if the standard would be unjust or inappropriate. Any deviation must be in writing with findings of fact.
It is an estimate for planning, not legal advice and not a court order. The judge decides the final amount and may depart from the guidelines when the standard figure would be unjust, inappropriate or not in the child's best interest (§ 81-6-202). Health insurance and work-related child care are handled separately from base support. To compare, run the same numbers through the Office of Recovery Services' official calculator.

Utah uses the income-shares model (Utah Code § 81-6-304). Both parents' gross monthly incomes are combined, a base support amount is read from the state guideline table for the number of children, and that amount is divided between the parents in proportion to their incomes and the parenting-time schedule.
Gross income from nearly every source, wages, salary, tips, bonuses, commissions, self-employment income, rental income, and more. The court can also impute income to a parent who is voluntarily unemployed or underemployed.
Overnights decide which worksheet applies. Each parent needs at least 111 overnights a year to use the joint physical custody worksheet: § 81-6-206(4)(a) adjusts support only for overnights over 110, so nothing changes until night 111. Utah defines joint physical custody as more than 30% of the year with each parent plus both contributing to the child's expenses beyond child support (§ 81-9-101). Below 111, the sole custody worksheet applies.
Yes. You can ask the court to recalculate support when there is a substantial change in circumstances, and you can generally request a review roughly every three years even without a major change.
Support continues until the child turns 18 or graduates from high school during their normal expected graduation year, whichever is later. It can extend for a child with a disability.
