This document provides a table showing the present value of a 1 unit annual annuity for "n" periods using interest rates from 1% to 40%. It was created by Angel Higuerey Gómez in November 2000 to calculate the future value of annuities using different interest rates over varying time periods. The table allows the user to look up the present value factor for any number of periods at any whole percentage interest rate between 1% and 40%.
