How the number of children changes the amount in Missouri
With Parent A earning $60,000 and Parent B $40,000, the guideline amount for 3 children is $1,187 a month, about 1.79 times the $664 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.
Missouri uses the income shares model and the official Form worksheet: the schedule gives the basic amount for the parents' combined monthly income, add-ons are added, and each parent is responsible for their share of the total.
