a) Dante Ryan is currently 50 years old. He plans to contribute $5,000 to his Roth IRA at the END of each year for 15 years, when he will retire at 65. Compute the future value of the annuity if this account returns 9%, compounded annually. N= i/y= PV= PMT= FV= 15115 9/1-9% -5000 ??? Remember to enter payment as a negative amount! b) Compute how much interest he earned during the 15-year term. Show work here: c) Dante wishes to run an experiment. If he were to save over a longer term, by starting to save earlier (at age 40 vs. 50), how much would he accumulate in his IRA? Recompute the amount of the annuity. How much will he accumulate (FV)? Still END. N= |i/y= PV= PMT= |FV= 65-40 25 0.09 -5000 ??? d) How much interest does Dante earn over the new 25-year term? e) Would you recommend that Dante start saving for retirement at 40 or 50? Why?
