trust that will be paid to Tom on his 70th birthday, January 1, 2045.
Each year since 2000, the grandfather put an additional $4,000 in the
account on Tom’s birthday, and the grandfather’s own trustee will continue
making the $4,000 payments until January 1, 2045, when a 46th and final
$4,000 contribution will be made on Tom’s 70th birthday. The grandfather
wants Tom to work, not to be a “trust fund baby,” but he also wants to
insure that Tom is well provided for in his old age.
The grandfather has until now has been disappointed with Jerry, hence has
not given him anything, but they recently reconciled, and the grandfather
has decided to make an equivalent provision for Jerry. He will make the
first payment to a trust for Jerry today, and he has instructed his

Answer: c
John and Julie Johnson are interested in saving for their retirement.
John and Julie have the same birthday–both are 50 years old today. They
started saving for their retirement on their 25th birthday, when they
received a $20,000 gift from Julieโs aunt and deposited the money in an
investment account.
Every year thereafter, the couple added another
$5,000 to the account.
(The first contribution was made on their 26th
birthday and the 25th contribution was made today on their 50th birthday.)
John and Julie estimate that they will need to withdraw $150,000 from the
account 3 years from now, to help meet college expenses for their 5
children.
The couple plans to retire on their 58th birthday, 8 years
from today. They will make a total of 8 more contributions, one on each
of their next 8 birthdays with the last payment made on their 58th
birthday. If the couple continues to contribute $5,000 to the account on
their birthday, how much money will be in the account when they retire?
Assume that the investment account earns 12% a year.

Kelly and Brian Johnson are a recently married couple whose parents
advised them to start saving immediately in order to have enough money
down the road to pay for their retirement and their childrenโs college
expenses. Today (t = 0) is their 25th birthday (the couple shares the
same birthday).
The couple plan to have two children (Dick and Jane). Dick is expected
to enter college 20 years from now (t = 20); Jane is expected to enter
college 22 years from now (t = 22).
So in years t = 22 and t = 23
there will be two children in college. Each child will take 4 years to
complete college, and college costs are paid at the beginning of each
year of college.

Answer: d
Hillary is trying to determine the cost of health care to college
students and parentsโ ability to cover those costs.
She assumes that
the cost of one year of health care for a college student is $1,000
today, that the average student is 18 when he or she enters college,
that inflation in health care cost is rising at the rate of 10% per
year, and that parents can save $100 per year to help cover their
childrenโs costs.
All payments occur at the end of the relevant
period, and the $100/year savings will stop the day the child enters
college (hence 18 payments will be made). Savings can be invested at a
nominal rate of 6%, annual compounding.
Hillary wants a health care
plan that covers the fully inflated cost of health care for a student
for 4 years, during Years 19 through 22 (with payments made at the end
of Years 19 through 22).
How much would the government have to set
aside now (when a child is born), to supplement the average parentโs
share of a childโs college health care cost?

independently for 3 years. He wants a retirement income that has, in the
first year, the same purchasing power as $40,000 has today. However, his
retirement income will be a fixed amount, so his real income will decline
over time. His retirement income will start the day he retires, 2 years
from today, and he will receive a total of 3 retirement payments.
Inflation is expected to be constant at 5%. Your father has $100,000

157. Today is Rachelโs 30th birthday.
Five years ago, Rachel opened a
brokerage account when her grandmother gave her $25,000 for her 25 th
birthday.
Rachel added $2,000 to this account on her 26 th birthday,
$3,000 on her 27th birthday, $4,000 on her 28th birthday, and $5,000 on
her 29th birthday. Rachelโs goal is to have $400,000 in the account by
her 40th birthday.
Starting today, she plans to contribute a fixed amount to the account
each year on her birthday. She will make 11 contributions, the first
one will occur today, and the final contribution will occur on her 40 th
birthday.
Complicating things somewhat is the fact that Rachel plans
to withdraw $20,000 from the account on her 35th birthday to finance the
down payment on a home. How large does each of these 11 contributions

Suppose you are deciding whether to buy or lease a car. If you buy the
car, it will cost $17,000 today (t = 0). You expect to sell the car four
years (48 months) from now for $6,000 (at t = 48). As an alternative to
buying the car, you can lease the car for 48 months. All lease payments
would be made at the end of the month.
The first lease payment would
occur next month (t = 1) and the final lease payment would occur 48
months from now (t = 48). If you buy the car, you would do so with cash,
so there is no need to consider financing.
If you lease the car, there
is no option to buy it at the end of the contract. Assume that there are
no taxes, and that the operating costs are the same regardless of whether
you buy or lease the car. Assume that all cash flows are discounted at a
nominal annual rate of 12%, so the monthly periodic rate is
1%.

Breakeven annuity payment
169.
Answer: a
Linda needs a new car and is deciding whether to buy or lease the car.
She estimates that if she buys the car, it will cost her $17,000 today (t
= 0) and that she would sell the car four years from now for $7,000 (at t
= 4). If she were to lease the car she would make a fixed lease payment
at the end of each of the next 48 months (4 years).
Assume that the
operating costs are the same regardless of whether she buys or leases the
car.
Assume that if she leases, there are no upfront costs and that
there is no option to buy the car after four years. Linda estimates that
she should use a 6% nominal interest rate to discount the cash flows.
What is the breakeven lease payment?
(That is, at what monthly lease
payment would she be indifferent between buying and leasing the car?)
a. $269.85
b. $271.59

Recall, we used BEGIN mode (because it is an annuity due), so it takes 16 payments before
the lifetime subscription is better. Since the 1st payment occurs today, the 16th payment
occurs at t = 15 (15 years from now). So, you must live for: 16 – 1 = 15 years.

Chapter 2: Time Value of Money
Students must understand that “simple interest with interest paid monthly” means that the
bank gets the interest at the end of each month, hence it can invest it, presumably at the same
nominal rate. This results in the same effective rate as if it were stated as “6%, monthly
compounding.” The problem can be worked most easily using the interest conversion feature
of a calculator. It could also be worked using the conversion formula. We applied the formula
using Excel.

There are 3 cash flow streams: the gift and the two annuities. The gift will grow for 10 years.
Then there is a 5year annuity that will compound for an additional 5 years. Finally, there is a
second 5year annuity. The sum of the compounded values of those three sets of cash flows
is the final amount.

This is a very difficult problem. It would not generally be appropriate for a regular inclass
exam. It would be better for a takehome exam. We must find a value of X such that the PV
of the positive CFs, discounted at 9%, will equal the initial negative CF.
The problem is relatively easy with Excel but quite hard with a calculator because it’s hard to
conceptualize the required setup and steps.
Excel solution: Set the problem up as shown below. Put a guess–we initially guessed
$10,000–in the boxed cell under the first X. The IRR initially is less than 9%, so raise the
guess, and keep iterating until IRR = 9%. This value of X is the required payment for the
investment to provide the 9% rate of return. The problem can be worked faster if you know
how to use Goal Seek; then you tell Excel to change the X cell to the value that causes IRR =

Answer: a EASY

Time value concepts
Answer: e
EASY
67.
Time value concepts
Answer: c
EASY
Statement a is false, because the more compoundings per year, the less
the present value of a lump sum. Statement b is false and statement c
is true, because the periodic rate is 5%.
Statement d is false,
because the more periods a lump sum is discounted, the less its present
value is.
Statement e is false, because the annuity has cash flows
occurring sooner than the lump sum is due, so the sum of the PVs of its
cash flows will be greater.
68.
Time value concepts
Answer: e
EASY
Since the effective rates are all the same, the correct answer must be
the investment that has the largest amount of money compounding for the
longest time, which is statement e. This can be proven by assuming an
effective annual rate and performing the calculations.
69.
Effective annual rate
Answer: b
EASY
The bank account that pays the highest nominal rate with the most
frequent rate of compounding will have the highest EAR. Consequently,
statement b is the correct choice.
70.
Effective annual rate
Answer: d
EASY
The investment with the highest nominal rate and most frequent
compoundings will have the highest effective rate.
For this reason,
Bank 4 (statement d) dominates Banks 13 (statements a, b, and c).
Therefore, Bank 4โs effective rate (8.328%) must be calculated and
compared to Bank 5โs effective rate (8.2%). Therefore, statement d is
the correct choice.
Page 92
Chapter 2: Time Value of Money
71.
Quarterly compounding
Answer: e
EASY
If the nominal rate is 8% and there is quarterly compounding, the periodic
rate must be 8%/4 = 2%.
The effective rate will be greater than the
nominal rate; it will be 8.24%. So the correct answer is statement e.
72.
Annuities
Answer: c
MEDIUM
Statement a is false, because the present value of an annuity due (all
else equal) is greater than the present value of an ordinary annuity,
since cash flows are received sooner and reinvested longer. Statements
b and e are false, because the present and future values of an annuity
due (all else equal) are also greater, since the cash flows are
reinvested longer. Statement c is true for the same reasons. Statement
d is false, because the difference in PVs of the two annuities will
change as interest rates change.
73.
Amortization
Answer: e
MEDIUM
Statement a is false, because the interest rate and annual payments are
positively correlated (higher rates = higher payments, and vice versa).
Statement b is false, because interest during Year 1 would be the interest
rate times the beginning balance, which are identical in both cases.
Statement c is false, because early payments in a loanโs life have a lot
of interest, but later payments include very little interest since the
balance is low at this point.
Statement d is false, because this
composition changes with each payment, as more principal and less interest
is paid with each payment. Statement e is true, because if the interest
rate is higher, then a greater proportion of total payments (and hence,
each individual payment) goes toward interest.
74.
Amortization
Answer: b
MEDIUM
Statement a is false, because the remaining balance will be the loan
amount less the amount paid toward principal.
Statement b is true,
because the percentage paid toward principal increases throughout the
loanโs life.
Statement c is false, because the payment will be same
each month.
Statement d is false, because the balance gets paid off
quicker at the end of a bondโs life when the balance is lower and more
of the payment goes toward principal.
Statement e is false, because
fixedrate means that the interest rate applied to the outstanding
balance (which does change) will be fixed.
75.
Amortization
Answer: a
MEDIUM
Statement a is false, because monthly payments will not decline over time,
they will stay the same. Statement b is true, because the percentage paid
toward interest declines over time. Statement c is true, because interest
due for every payment gets progressively smaller, which means that the
portion toward principal gets larger. Statement d is true, because if the
interest rate is lower, less is paid toward interest.
Statement e is
Chapter 2: Time Value of Money
Page 93
76.
true. Therefore, answer choice a is the correct answer.

FV of an annuity
Answer: d
First, find the present values today of the two withdrawals to occur on
the 25th and 30th birthdays (in the 5th and 10th year of the problem,
respectively).
PV today of $5,000 withdrawal five years from now:
N = 5; I/YR = 12; PMT = 0; FV = 5000; and solve for PV = $2,837.13.
PV today of $10,000 withdrawal 10 years from now:
N = 10; I/YR = 12; PMT = 0; FV = 10000; and solve for PV = $3,219.73.
Now, we subtract the PV of these withdrawals from our initial investment:
$5,000.00 – $2,837.13 – $3,219.73 = $1,056.86.
Finally, we have our simple TVM setup with N, I/YR, PV, and PMT, solving
for FV:
N = 45; I/YR = 12; PV = 1056.86; PMT = 500; and solve for FV =

FV of annuity due
Answer: a
First, convert the 9% return with quarterly compounding to an effective
rate of 9.308332%.
With a financial calculator, NOM% = 9; P/YR = 4;
EFF% = 9.308332%. (Donโt forget to change P/YR = 4 back to P/YR = 1.)
Then calculate the FV of all but the final payment.
BEGIN MODE (1
P/YR) N = 9; I/YR = 9.308332; PV = 0; PMT = 1500; and solve for FV =
$21,627.49. You must then add the $1,500 at t = 9 to find the answer,
$23,127.49.

EAR and FV of annuity
Answer: c
First, we must find the appropriate effective rate of interest.
your calculator enter the following data as inputs as follows:
NOM% = 6; P/YR = 12; and solve for EFF% = 6.167781%.
Using
Since the contributions are being made every 6 months, we need to
determine the nominal annual rate based on semiannual compounding. Enter
the following data in your calculator as follows:
EFF% = 6.167781%; P/YR = 2; and solve for NOM% = 6.0755%.
Now, use the periodic rate 6.0755%/2 = 3.037751% to calculate the FV of
the annuities due. Now, we must solve for the value of all contributions
as of the end of Year 2.
Enter the following data inputs in your
calculator:
N = 4; I/YR = 3.037751; PV = 1000; PMT = 1000; and solve for FV =
$5,313.14.
Chapter 2: Time Value of Money
Page 113
So, these contributions will be worth $5,313.14 as of the end of Year 2.
Now, we must find the value of this investment after the eighth year. For
this calculation, we can use annual periods and the effective annual rate
calculated earlier.
Enter the following data as inputs to your
calculator:
N = 6; I/YR = 6.167781; PV = 5313.14; PMT = 0; and solve for FV =
$7,608.65 ๏ป $7,609.

FV of investment account
Answer: b
We need to figure out how much money they would have saved if they
didnโt pay for the college costs.
N = 40; I/YR = 10; PV = 0; PMT = 12000; and solve for FV = $5,311,110.67.
Now figure out how much they would use for college costs. First get the
college costs at one point in time, t = 20, using the cash flow register.
CF0 = 58045; CF1 = 62108; CF2 = 66,456 ๏ด 2 = 132912 (two kids in school);
CF3 = 71,108 ๏ด 2 = 142216; CF4 = 76086; CF5 = 81411; I/YR = 10; NPV =
$433,718.02.
The value of the college costs at year t = 20 is $433,718.02. What we
want is to know how much this is at t = 40.
N = 20; I/YR = 10; PV = 433718.02; PMT = 0; and solve for FV =
$2,917,837.96.
The amount in the nest egg at t = 40 is the amount saved less the
amount spent on college.
$5,311,110.67 – $2,917,837.96 = $2,393,272.71 ๏ป $2,393,273.

Find out how much Steve and Robert have in their accounts today:
You can get this from analyzing Steveโs account.
END mode: N = 9; I/YR = 6; PV = 5000; PMT = 5000; and solve
for FV = $65,903.9747.
Alternatively, BEGIN mode: N = 9; I/YR = 6; PV = 0; PMT =
5000; and solve for FV = $60,903.9747.
Then add the $5,000 for the last payment to get a total of
$65,903.9747.
This is also the value of Robertโs account today.
Find out how much Robert would have had if he had never
withdrawn anything:
END mode: N = 9; I/YR = 12; PV = 5000; PMT = 5000; and solve
for FV = $87,743.6753.
Alternatively, BEGIN mode: N = 9; I/YR = 12; PV = 0; PMT =
5000; and solve for FV = $82,743.6753.
Then add the $5,000 for the last payment to get a total of
$87,743.6753.
Find the difference in the value of Robertโs account due to
the withdrawal made:
However, since he took money out at age 27, he has only
$65,903.9747. The difference between what he has and what he
would have had is:
$87,743.6753 – $65,903.9747 = $21,839.7006.
Determine the amount of Robertโs withdrawal by discounting the
value found in Step 3:

Nonannual compounding
Answer: a
To compare these alternatives, find the present value of each strategy
and select the option with the highest present value.
Option 1 can be valued as an annuity due.
Enter the following input data in the calculator:
BEGIN mode (to indicate payments will be received at the start of the
period) N = 12; I/YR = 12/12 = 1; PMT = 1000; FV = 0; and solve for PV
= $11,367.63.
Option 2 can be valued as a lump sum payment to be received in the future.
Enter the following input data in the calculator:
END mode (to indicate the lump sum will be received at the end of the year)
N = 2; I/YR = 12/2 = 6; PMT = 0; FV = 12750; and solve for PV =
$11,347.45.
Chapter 2: Time Value of Money
Page 123
Option 3 can be valued as a series of uneven cash flows.
The cash
flows at the end of each period are calculated as follows:
CF0 = $0.00; CF1 = $800.00; CF2 = $800.00(1.20) = $960.00; CF3 = $960.00
(1.20) = $1,152.00; CF4 = $1,152.00(1.20) = $1,382.40; CF5 = $1,382.40
(1.20) = $1,658.88; CF6 = $1,658.88(1.20) = $1,990.66; CF7 = $1,990.66
(1.20) = $2,388.79; CF8 = $2,388.79(1.20) = $2,866.54.
To find the present value of this cash flow stream using your financial
calculator enter:
END mode (to indicate the cash flows will occur at the end of each
period) 0 CFj; 800 CFj; 960 CFj; 1152 CFj; 1382.40 CFj; 1658.88 CFj;
1990.66 CFj; 2388.79 CFj; 2866.54 CFj (to enter the cash flows);I/YR =
