Note: All incomes must be monthly net (after taxes). The calculator uses Pennsylvania’s 2024 guidelines: combined income × percentage (25% for 1 child, 33% for 2, etc.), then split by each parent’s income share. The larger obligation is displayed.

Frequently Asked Questions
Pennsylvania uses the Income Shares Model. The basic support obligation is determined by the combined monthly net income of both parents and the number of children, using a percentage (e.g., 25% for one child, 33% for two). Each parent's share is proportional to their income.
Net income includes wages, salaries, bonuses, commissions, self-employment income, and certain benefits. Deductions may include taxes, mandatory retirement contributions, and health insurance premiums.
This calculator provides a basic estimate. Pennsylvania courts may adjust support based on custody arrangements (e.g., more than 50% parenting time). Consult a family law attorney for a precise calculation.
