How Child Support is Calculated in Pennsylvania


Child support payments in Pennsylvania are calculated using the income shares only method. Payments depend on the combined income of the parents as well as the number of children eligible for support. A bigger combined income or extra children typically means higher payments.

The amounts transferred also depend on each parent’s income share or income percentage. Pennsylvanians paying the most support are non-custodial parents with high incomes. The biggest receivers are low-income parents with primary physical custody and a high-earning payer.

We refer to the method as "income shares only" since Pennsylvania lacks a well-defined way of adjusting payments for the exact amount of parenting time each parent contributes. A parent’s share of care time is not a detailed part of the guidelines, as is usually the case with income sharing models.

The parent with more than 50% of the overnights has primary custody. Note that a parent with partial custody of the child(ren) is entitled to a payments discount if he or she has more than 40% of overnights.

Factors affecting child support calculations are: (a) the physical custody schedule (b) the number of children covered by the support order (c) the monthly after-tax incomes of the parties and (d) certain additional expenses the parties may incur for the care of children.
