Our Pennsylvania child support calculator applies the state's income shares model as outlined in Pennsylvania Rule of Civil Procedure 1910.16-2. The calculation combines both parents' incomes to determine a basic support obligation, then divides this obligation proportionally based on each parent's income share. Custody time and additional expenses are factored into the final support amount.
Step 1: Combined Income = Parent 1 Income + Parent 2 IncomeStep 2: Basic Obligation = Combined Income × Guideline %Step 3: Each Parent's Share = (Income / Combined) × Basic ObligationStep 4: Apply Custody Adjustment (if 40%+ time)Step 5: Add Proportional Share of Additional ExpensesPennsylvania uses guideline percentages that vary by number of children and income level. Shared custody adjustments apply when a parent has 40% or more custody time (approximately 146 overnights per year).
Pennsylvania follows the income shares model, which is based on the economic principle that children should receive the same proportion of parental income they would have received if the parents lived together. The state provides detailed guidelines and schedules based on combined income levels and number of children.
