Half of what the receiving parent pays is added to the amount; half of what the paying parent pays is credited against it, to the cent. Uninsured medical costs are split equally as they come up.

How Utah works it out
Utah uses the income shares model. The parents' adjusted gross incomes are added together and the statutory table gives the base combined child support obligation for that income and number of children. Each parent is responsible for their share of income.
Gross income from almost all sources counts, before taxes, rounded to the nearest dollar. Child support a parent was previously ordered to pay for other children is subtracted. Alimony ordered in this case is neither added nor subtracted.
When each parent has at least 111 overnights a year (joint physical custody), the parent with fewer overnights takes their share of the table amount and subtracts a credit for the overnights above the threshold. If the result is below zero, the other parent pays the difference. With an equal schedule, the parent with the lower income is treated as having the extra overnight.
