How the number of children changes the amount in South Dakota

With Parent A earning $60,000 and Parent B $40,000, the guideline amount for 4 children is $1,345 a month, about 1.93 times the $697 for one child. Support rises with each child, but by less than the first child's amount, because the guidelines reflect how households share costs among children.

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.

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.
