The children's health insurance is shared by income, with a credit for the parent who pays it, and a parent's share is limited to 8% of their net income. Child care, less a federal credit counted at 25% of the eligible expense, and uninsured health costs above $250 per child a year are shared the same way.

How South Dakota works it out
South Dakota uses the income shares model: the schedule gives the support for the parents' combined monthly net income, and the noncustodial parent's share of it, by percentage of combined income, is the order.
Net income is gross income minus federal income tax at the single rate for a monthly payroll period, Social Security and Medicare, retirement plan contributions up to 10% of gross income, work expenses an employer doesn't repay, and payments on other support orders. South Dakota has no income tax. A parent is presumed able to earn at least the state minimum wage of $11.85 an hour for 1,820 hours a year.
With a shared parenting plan of at least 180 nights a year in each home, the court may grant a cross credit: the schedule amount is increased by half, shared by income, and each parent's share is multiplied by the other parent's share of the nights, then offset. A partial abatement for six or more nights a month is up to the court and isn't estimated.
