* Note: A constant rate of simple interest implies a decreasing effective rate of interest for periods over one year.
This form assumes that interest accrues from the end of the first week through to the end of the payments period. If this assumption is inappropriate for your calculation, please consult another source.
Disclaimer: The appropriate formula for the calculation of statutory interest in accordance with Section 406.1(a) of the Pennsylvania Workers' Compensation Act has not yet been judicially determined with certainty. This calculator provides for two methods to calculate interest, but neither of these methods may ultimately be methods approved by the Court.
