Child Support spelled in blocks with family figures, a gavel, and cash

This free calculator estimates your monthly child support obligation under Utah’s Income Shares Model, using the same base combined-obligation schedule and overnight-adjustment formulas found in Utah Code Title 81, Chapter 6. Enter each parent’s gross monthly income, the number of children, and the custody arrangement to see an estimate update instantly.

How This Calculator Works

Utah determines child support using the combined gross monthly income of both parents and the number of children to look up a base obligation from the statutory schedule at § 81-6-304. That base amount is then split between the parents proportional to their share of combined income.

  • Sole custody (§ 81-6-205): the non-custodial parent pays their income share of the base obligation.
  • Joint custody (§ 81-6-206, 111+ overnights each): the paying parent’s obligation is reduced based on the number of overnights above 110, at graduated rates.

This tool provides an estimate only — it is not legal advice, and courts retain discretion to deviate from the guideline calculation based on exceptional circumstances under § 81-6-205(2). For a precise number or help applying it to your case, request a consultation with one of our Utah child support attorneys.

Frequently Asked Questions

Is this calculator’s result legally binding?

No. This tool provides an estimate based on Utah’s statutory guidelines. Only a court order, or a stipulation approved by the court, establishes an actual child support obligation.

What counts as gross monthly income?

Per Utah Code Ann. §81-6-203, gross income includes wages, self-employment net income, rental income, dividends, and most other recurring income. Voluntary underemployment may result in income being imputed.

How do overnights affect the calculation in joint custody?

Under §81-6-206, once a parent has at least 111 overnights per year, their share of the base obligation is reduced on a sliding scale for overnights between 111–130 and again for overnights above 130.

Can the court order a different amount than this estimate?

Yes. Courts may deviate from the guideline calculation under §81-6-205(2) based on factors like extraordinary medical costs, special needs, or other exceptional circumstances.
