How the number of children changes the amount in Oregon

With Parent A earning $60,000 and Parent B $40,000, the guideline amount for 4 children is $991 a month, about 1.85 times the $535 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.

Oregon uses the income shares model: the obligation scale gives the basic support obligation for the parents' combined monthly adjusted income and number of children, and each parent is responsible for their percentage share.
