Chapter 5 The Time Value of Money
5.1 Learning Objective 1
1) The time value of money is the opportunity cost of passing up the earning potential of a dollar
today.
2) A rational investor would prefer to receive $1,200 today rather than $100 per month for 12
months.
3) A timeline identifies the timing and amount of a stream of cash flows, along with the interest
rate it earns.
4) Timelines are used for simple time value of money problems, but cannot be used for more
complex problems.
5) If you only earned interest on your initial investment, and not on previously earned interest, it
would be called simple interest.
6) An investment earning simple interest is preferred over an investment earning compound
interest because the simplicity adds value.
7) When using a financial calculator, cash outflows generally have to be entered as negative
numbers, because a financial calculator sees money “leaving your hands.”
8) $10,000 invested at 10% per year for 5 years earns interest equal to $6,105.10; therefore,
$10,000 invested at 10% per year for 10 years will earn interest equal to $12,210.20 (2 times
$6,105.10).
9) When solving time value of money problems on a financial calculator, you must select the
“end mode” when you enter the final years cash flow.
10) When solving a problem involving an annuity due, you must select the “beg” or beginning
mode on your financial calculator.
11) When solving time value of money problems using Excel, the type = 0 variable means
payments are made at the end of each period, and the type = 1 variable means payments are
made at the beginning of each period.
12) Inputs using an Excel spreadsheet are almost identical to those on a financial calculator,
except the interest rate is entered either as a decimal (.05) or a whole number followed by a %
sign (5%) rather than simply a whole number (5) as you would enter using a financial calculator.
13) Suppose a corporation can change its depreciation method so that its tax payments will
decrease by $1,000 this year but increase by $1,000 next year.
A) The change will have no impact on the value of the company because its cash flow over time
will be the same.
B) The change will decrease the value of the company because investors don’t like changes in
accounting methods.
C) The change will decrease the value of the company because lower tax payments this year
result from lower reported income.
D) The change will increase the value of the company because the value of the cash savings this
year exceeds the cost of the cash payments next year.
5.2 Learning Objective 2
1) Tim has $100 in a bank account paying 2% interest per year. At the end of 5 years, Tim’s bank
account balance will be $110 if interest is not compounded, but will be greater than $110 if
interest is compounded.
2) At an annual interest rate of 9%, an initial sum of money will double approximately every 8
years.
3) A car manufacturer offers either $2,000 cash back or zero percent financing for 5 years. A
rational consumer will always take the cash back because money received today is worth more
than money received in the future.
4) The present value of a single future sum of money is inversely related to both the number of
years until payment is received and the discount rate.
5) The same underlying formula is used for computing both the future value and present value.
6) Artificially low interest rates helped create the housing bubble because low interest rates (r
value) create higher values (higher PVs).
7) The present value of a single future sum
A) increases as the number of discount periods increases.
B) is generally larger than the future sum.
C) depends upon the number of discount periods.
D) increases as the discount rate increases.
8) U.S. Savings Bonds are sold at a discount. The face value of the bond represents its value on
its future maturity date. Therefore,
A) the current price of a $50 face value bond that matures in 10 years will be greater than the
current price of a $50 face value bond that matures in 5 years.
B) the current price of a $50 face value bond that matures in 10 years will be less than the current
price of a $50 face value bond that matures on 5 years.
C) the current prices of all $50 face value bonds will be the same, regardless of their maturity
dates because they will all be worth $50 in the future.
D) the current price of a $50 face value bond will be higher if interest rates increase.

using the present value of a lump sum formula, even if the amount of each annuity payment is
unknown.
4) If the interest rate is positive, then the future value of an annuity due will be greater than the
