John Fillmore’s lifelong dream is to own his own fishing boat to use in his retirement. Jack has recently come into an inheritance of $400,000. He estimates that the boat he wants will cost $300,000 when he retires in 5 years. How much of his inheritance must he invest at an annual rate of 12% (compounded annually) to buy the boat at retirement? BE67

Annuity requires the following:
(1) (2) (3) Periodic payments or receipts (called rents) of the same amount, The samelength interval between such rents, and Compounding of interest once each interval. Two Types Ordinary annuity rents occur at the end of each period. Annuity Due rents occur at the beginning of each period. Ordinary v. Annuity Due
Note: The difference between an ordinary annuity and an annuity due is that:
– Each rent or payment compounds (interest added) one more period in a annuity due, future value situation. – Each rent or payment is discounted (interest removed) one less period under the annuity due situation. – Given the same i, n and periodic rent, the annuity due will always yield a greater present value (less interest removed) and a greater future value (more interest added).
