DCF 150.035(1)(b)4. 4. Multiply the amount determined for each parent under subd. 3. by the proportion of the time that the child spends with the other parent to determine each parent’s child support obligation.

DCF 150.035(1)(b)5. 5. Offset resulting amounts under subd. 4. against each other. The parent with a greater child support obligation is the shared-placement payer. The shared-placement payer shall pay the lesser of the amount determined under this subdivision or the amount determined using the designated percentage. If the shared-placement payer is also a low-income or high-income payer, the court may combine the provisions of either s. DCF 150.04 (4) or (5) with the provisions of this section.

DCF 150.035(1)(b)6. 6. In addition to the child support obligation determined under subd. 5., the court shall assign responsibility for payment of the child’s variable costs in proportion to each parent’s share of physical placement, and based upon a detailed list of the variable costs provided by the parties. Due consideration shall be given to a disparity in the parents’ income and the transportation costs associated with each parent’s respective periods of physical placement. The court shall direct the manner of payment of a variable cost order to be either between the parents or from a parent to a third-party service provider. The court shall not direct payment of variable costs to be made to the department or the department’s designee.

DCF 150.035(1)(b)7. 7. A change in the child’s variable costs shall not in and of itself be considered a substantial change in circumstances sufficient to justify a revision of a judgment or order under s. 767.59, Stats.

DCF 150.035 Note Note: The following example shows how to calculate the child support obligations of shared-placement parents.

DCF 150.035 Note Number of children: Two

DCF 150.035 Note Parent A:   $2,000 monthly income available for child support

DCF 150.035 Note   Court-ordered placement of the child for 219 days a year or 60%.

DCF 150.035 Note Parent B:   $3,000 monthly income available for child support

DCF 150.035 Note   Court-ordered placement of the child for 146 days a year or 40%.

DCF 150.035 Note Example of equivalent care:

DCF 150.035 Note Number of children: Two

DCF 150.035 Note Parent A: $2,000 monthly income available for child support

DCF 150.035 Note Parent A has court-ordered placement of the child 271 days a year or 74%.

DCF 150.035 Note Parent B: $3,000 monthly income available for child support

DCF 150.035 Note Parent B has court-ordered placement of the child 94 days a year or 26%.

DCF 150.035 Note Parent B also provides day care 4 days a week from 3 pm – 9 pm and

DCF 150.035 Note Provides dinner to the children 46 weeks per year.

DCF 150.035 Note (4) 6 hour blocks per week = 2 overnights X 46 weeks= 92 overnights per year

DCF 150.035 Note Total number of overnights = 457 (271 + 94 + 92)

DCF 150.035 Note Parent A = 59%

DCF 150.035 Note Parent B = 41%

DCF 150.035 Note Time with Parent A = 59% (271/457 = .59)

DCF 150.035 Note Time with Parent B = 41% (94 +92)/457=.407
