I do agree with the other person as far as the calculations that are needed to arrive at each annual contribution. However, I disagree with him using the PRESENT VALUE (PV) of AN

document.write( "So, during the 5-YEAR distribution-period, instead of using the PRESENT VALUE of AN ORDINARY ANNUITY of $218,247.16, the PRESENT VALUE of AN ANNUITY DUE of $227,413.55 should be used. \r
