How Child Support is Calculated in Pennsylvania
Pennsylvania uses an Income Shares model based on the statewide support guideline (Pa.R.C.P. 1910.16-3). The combined monthly net income determines a basic support obligation, which is then divided proportionally between the parents. Pennsylvania also includes a self-support reserve to protect low-income obligors.
