Support Calculator
Calculating for: Massachusetts
Formula Description
Massachusetts combines both parents' available weekly incomes and derives the base order from Table A of the Child Support Guidelines Worksheet. The obligation is allocated according to each parent's share of combined available income.
Rates & Multipliers
Set by a graduated bracket table applied to weekly income, not by flat percentage.
Income Caps
The 2025 Guidelines calculate base support on combined available income up to $450,000 per year, raised from $400,000. Above that figure the guideline amount is the minimum presumptive order and any increase is at the court's discretion.
