This Child Support Calculator uses the June 15, 2018 Massachusetts Child Support Guidelines, which are required for all child support orders in MA beginning June 15, 2018. Please feel free to contact Attorney Julia Rueschemeyer with any questions you have about divorce mediation or uncontested divorce.
After calculating your child support, you can click the button “Save Results to Worksheet PDF”, and the calculator will download a filled-in, court-ready 2018 Child Support Guidelines Worksheet.
If you find that changing childcare and health care costs affects the overall child support amount in strange ways, you might consider consulting the 2018 Deviation Calculator.
Bug Alert: If you used this calculator before the morning of June 19 AND one spouse has income of $0, the calculator may have given an artificially low child support number.
To calculate how much child support you should pay or receive, simply:
a) Enter a name for yourself and your spouse (fake names are fine)
b) Enter the number of children under age 18 that you have together
c) Enter the number of children you have together who i) have turned 18 but not yet turned 23 and ii) live with you or are supported by you. If a child is still attending high school, treat the child as under 18.
d) Indicate the amount of time that the child spends with each parent by choosing from among 4 choices: about 50% time with each parent, about 1/3 of the time with you and 2/3 of the time with your spouse, about 2/3 of the time with you and 1/3 of the time with your spouse, or (less common) “split” custody, in which different children have primary residence with different parents. Choose the one that is closest to your situation.
