Factors in Child Support Calculation
Parental Income
Both parents’ gross incomes are considered in Massachusetts. This includes wages, salaries, commissions, bonuses, self-employment income, and certain benefits. The combined income determines the basic support obligation according to Massachusetts guidelines.
Number of Children
Support amounts increase with each additional child. Massachusetts uses a combined income model that adjusts based on the total number of children requiring support.
Custody Arrangement
The time each parent spends with the child affects support calculations. Shared custody (where the child spends at least 1/3 of time with each parent) typically reduces the support amount compared to sole custody arrangements.
Additional Expenses
Extraordinary expenses like health insurance premiums, child care costs, educational expenses, and special needs are added to the basic support obligation and allocated between parents based on income share.
