Appendix C
Time Value of Money



review Questions
Question C-1 (LO C-1) Interest is the cost of borrowing money. Simple
interest is interest we earn on the initial investment only.
Compound interest is the interest we earn on the initial investment plus previous interest. We use
compound interest in calculating the time value of money.

Question C-2 (LO C-2)
To compute a future value, you need to know three amounts: (1) initial investment, (2) the interest
rate per period and (3) the number of periods.

Question C-3 (LO C-2)
Present value tells us the value today of receiving some larger amount in the future. The discount
rate is the rate at which we would be willing to give up current dollars for future dollars.


Question C-4 (LO C-3)
Annuities represent cash payments of equal amounts over equal time intervals.

Question C-5 (LO C-3)
The present value of an annuity is the sum of the present values of a series of cash payments.

Oprah should choose the second option, the investment on which interest is
