How the number of children changes the amount in Massachusetts

With Parent A earning $60,000 and Parent B $40,000, the guideline amount for 4 children is $1,941 a month, about 1.85 times the $1,049 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.

Massachusetts uses an income shares formula: Table A gives the support for one child from the parents' combined weekly available income, adjusted for the number of children and for children aged 18 or older, and each parent is responsible for their share of income.
