Massachusetts: 50/50 Equal Physical Custody Child Support Calculator
When parents share equal physical custody (182.5 or 183 overnights per year), child support calculations shift from traditional sole-custody schedules to shared parenting cross-credit offset formulas. Calculate exact cross-credit amounts and determine how state laws address dual-household expenditures.
Section II.D requires a reciprocal two-step calculation: calculate support as if each parent had sole custody, then pay the net differential.

Key Legal Principles for 50/50 Shared Custody in Massachusetts
Statutory Framework & Court Standards
- Equal physical custody does NOT mean zero child support if parental incomes are unequal.
- Most Income Shares jurisdictions apply a shared parenting multiplier (1.5x) or reciprocal offset method.
- Fixed duplicated child expenditures (housing, bedrooms, clothing, utilities) are accounted for in cross-credit offsets.
- Health insurance and out-of-pocket medical add-ons remain apportioned strictly by income shares.
