CHAPTER 8
The Time Value of Money
THINKING BEYOND THE QUESTION
How much will it cost to borrow money?
A shorter borrowing period means that a creditor will receive repayment
of a loan sooner than if the borrowing period is longer. Consequently, the
money that is borrowed is at risk over a shorter period. The lender has

Q8-1 Future value and present value are based on the concept of interest. Both
recognize that, when invested at a rate of interest, an amount of money
will grow to a larger amount as time passes. Future value is the amount

The difference relates to the length of time the money is invested.
Time is a powerful component of the value of money. Even though
an investor may be able to save only small amounts, it is important
to begin investing early rather than wait until later and have to invest
larger amounts or look for higher paying, but riskier investments.

C. The amounts are larger in part B because the amount of interest
earned is greater. The reason for the greater amount of interest is
that each $3,000 IRA contribution was on deposit one extra period.
