To calculate Child Support payments you will need:

  • Your last paycheck stub, W-2s, or an estimate of your monthly gross income.
  • Your spouse’s last paycheck stub, W-2s, or an estimate of your spouses’s monthly gross income.
  • The combined income table at the Utah.gov site
  • The appropriate child support worksheet.

In Utah, child support is calculated using a child support worksheet. There are three different child support worksheets. Below you will determine which worksheet you should use.

Child Support Worksheets

  • Sole custody worksheet: Use this worksheet if only one parent has the child(ren) for greater than 111 overnights annually.
  • Joint custody worksheet: Use this worksheet if each parent has the child(ren) for greater than 110 overnights annually.
  • Split custody worksheet: Use this worksheet if there is more than one minor child in the family and each parent has at least one of the children in their home as if they were the sole custodial parent.

Please be sure to read this succinct description of how custody is defined in Utah.

Also, the calculation that you are doing is a rough estimate. The parties gross pay may fluctuate. One of the parties may receive regular and expected overtime as part of their work. One parent may have more than one job or source of income and there is an argument as to which source is the primary source of income. This worksheet calculation is intended to provide you with an idea of the child support that may result in your case. However, it is not intended to constitute legal advice and may or may not be accurate as to what the court will award.

Notice that the calculation is based on gross income while alimony calculations are based on net incomes. There is no alimony worksheet; alimony awards are based on a number of factors and is very difficult to predict.
