This calculator determines the interest of a series of equal payments for any
date range. All pay periods are assumed to be consecutive. If the last
week for a given date range is fractional, this calculator prorates the weekly
amount accordingly, calculates the number of days late for this fractional
payment, determines the correct Daily Amount, and figures interest accordingly.
This interest is added to the interest for the consecutive whole weeks. If the
rate of payment changes, or it lost time is intermittent, separately calculate
each payment period. For additional calculations, change the values in the
appropriate boxes, and click "calculate."
