Total value in 3 years = $8,817.98 + $4,665.60 + $4,320 + $4,000 = $21,803.58
(6.1 slides)

Question 12

Suppose you invest $500 in a mutual fund today and $600 in one year.
If the fund pays 9% annually, how much will you have in two years?

Answer 12

FV = $500 × (1.09)2 + $600 × (1.09) = $1,248.05

Question 13

Suppose you plan to deposit $100 into an account in one year and $300 into the account in three years.
How much will be in the account in five years if the interest rate is 8%?

Answer 13

FV = $100 × (1.08)4 + $300 × (1.08)2 = $136.05 + $349.92 = 485.9

Question 14

You are offered an investment that will pay you $200 in one year, $400 the next year, $600 the year after, and $800 at the end of the following year. You can earn 12% on similar investments.
How much is this investment worth today?

Answer 14

Year 1 CF: $200/(1.12)1 = $178.57
Year 2 CF: $400/(1.12)2 = $318.88
Year 3 CF: $600/(1.12)3 = $427.07
Year 4 CF: $800/(1.12)4 = $508.41
=> Total PV = $178.57 + $318.88 + $427.07 + $508.41 = $1,432.93

Question 15

Your broker calls you and tells you that he has this great investment opportunity. If you invest $100 today, you will receive $40 in one year and $75 in two years.
If you require a 15% return on investments of this risk, should you take the investment?

Answer 15

PV = $40/(1.15)1 = $34.78
PV = $75/(1.15)2 = $56.71
=> PV = $34.78 + $56.71= $91.49 < $100

Question 16

You are offered the opportunity to put some money away for retirement. You will receive five annual payments of $25,000 each beginning in 40 years.
How much would you be willing to invest today if you desire an interest rate of 12%?

Answer 16

𝑃𝑉=$25,000/(1+0.12)^40 +$25,000/(1+0.12)^41 +$25,000/(1+0.12)^42 +$25,000/(1+0.12)^43 +$25,000/(1+0.12)^44 =$268.67+$239.88+$214.18+$191.23+$170.74=$1,084.71

Question 17

Suppose you are looking at the following possible cash flows: Year 1 CF = $100; Years 2 and 3 CFs = $200; Years 4 and 5 CFs = $300. The required discount rate is 7%.
What is the value of the cash flows at year 5?
What is the value of the cash flows today?
What is the value of the cash flows at year 3?

Answer 17

Value at year 5 = 131.08 + 245.01 + 228.98 + 321 + 300 = 1226.07
Present value today = 93.46 + 174.69 + 163.26 + 228.87 + 213.90 = 874.18 (difference due to rounding)

Value at year 3 = 114.49 + 214 + 200 + 280.37 + 262.03 = 1070.89

How much can you borrow?

Question 22

Suppose you win the Publishers Clearinghouse $10 million sweepstakes. The money is paid in equal annual installments of $333,333.33 over 30 years.
If the appropriate discount rate is 5%, how much is the sweepstakes actually worth today?

Answer 22

PV = $333,333.33 × [1 – 1/1.0530]/0.05 = $5,124,150.29

Question 23

You know the payment amount for a loan and you want to know how much was borrowed.
Do you compute a present value or a future value?
You want to receive $5,000 per month in retirement. If you can earn 0.75% per month and you expect to need the income for 25 years, how much do you need to have in your account at retirement?

Answer 23

PV = 5000[1 – 1 / 1.0075300] / .0075 = 595,808

Question 24

Suppose you want to borrow $20,000 for a new car. You can borrow at 8% per year, compounded monthly (8%/12 = 0.66667% per month).
If you take a 4-year loan, what is your monthly payment?

Answer 24

$20,000 = C × [1 – 1/1.006666748]/0.0066667
=> C = $488.26

Question 25

You ran a little short on your February vacation, so you put $1,000 on your credit card. You can only afford to make the minimum payment of $20 per month. The interest rate on the credit card is 1.5% per month.
How long will you need to pay off the $1,000

Answer 25

$1,000 = $20 × (1 – 1/1.015t)/0.015
0.75 = 1 – 1/1.015t
1/1.015t = 0.25
1/0.25 = 1.015t
t = ln(1/.25)/ln(1.015) = 93.111 months or 7.76 years

Question 26

Suppose you borrow $2000 at 5% and you are going to make annual payments of $734.42.
How long before you pay off the loan?

Answer 26

=> t = ln(1.157624287)/ln(1.05) = 3 years

Question 27

You want to receive $5000 per month for the next 5 years.
How much would you need to deposit today if you can earn 0.75% per month?

Answer 27

PV = 5000(1 – 1 / 1.007560) / .0075 = 240,867

Question 28

Suppose you begin saving for your retirement by depositing $2000 per year in an RRSP.
If the interest rate is 7.5%, how much will you have in 40 years?

Answer 28

FV = $2,000 × (1.07540 – 1)/0.075 = $454,513.04

Question 29

You are saving for a new house and you put $10,000 per year in an account paying 8% compounded annually. The first payment is made today.
How much will you have at the end of 3 years?

Answer 29

FV = $10,000 × [(1.083 – 1)/0.08] × (1.08) = $35,061.12

Question 30

The Home Bank of Canada want to sell preferred stock at $100 per share. A very similar issue of preferred stock already outstanding has a price of $40 per share and offers a dividend of $1 every quarter.
What dividend would the Home Bank have to offer if its preferred stock is going to sell?

Answer 30

First, find the required return for the comparable issue:
40 = 1/r
=> r = 0.025 or 2.5% per quarter
Then, using the required return found above, find the dividend for new preferred issue:
$100 = C/0.025
=> C = $2.50 per quarter

Question 31

Hoffstein Corporation is expected to pay a dividend of $3 per share next year. Investors anticipate that the annual dividend will rise by 6% per year forever. The required rate of return is 11%.
What is the price of the stock today?

Answer 31

Question 34

You are considering preferred stock that pays a quarterly dividend of $1.50.

If your desired return is 3% per quarter, how much would you be willing to pay?

Answer 34

50

Question 35

What is an effective annual rate

Answer 35

This is the actual rate paid (or received) after accounting for compounding that occurs during the year.
If you want to compare two alternative investments with different compounding periods, you need to compute the EAR for both investments and then compare the EAR’s

Question 36

Annual Percentage rate

Answer 36

This is the annual rate that is quoted by law

By definition APR = period rate times the number of periods per year

Period rate = APR/number of periods per year

Question 37

Suppose you can earn 1% per month on $1 invested today.
What is the APR?
How much are you effectively earning?

Answer 37

APR: 1% × 12 = 12%

Earning: FV = $1 × (1.01)^12 = 1.1268
=> Rate = (1.1268 – 1)/1 = 0.1268 or 12.68%

Question 38

You are looking at two savings accounts. One pays 5.25%, with daily compounding. The other pays 5.3% with semiannual compounding.
Which account should you use?

Answer 38

First account:
EAR = (1 + 0.0525/365)365 – 1 = 0.0539 or 5.39%
Second account:
EAR = (1 + 0.053/2)2 – 1 = 0.0537 or 5.37%
You should choose the first account (the account that compounds daily), because you are earning a higher effective interest rate.

Question 39

Suppose you want to earn an effective rate of 12% and you are looking at an account that compounds on a monthly basis

Answer 39

APR=12 × [(1+0.12)^(1⁄12)−1]=0.1138655152 or 11.39%

Question 40

Suppose you want to buy a new computer system and the store is willing to allow you to make monthly payments. The entire computer system costs $3,500. The loan period is for 2 years and the interest rate is 16.9% with monthly compounding.
What is your monthly payment?

Answer 40

Monthly rate = 0.169/12 =.0140833333
Number of months = 2 × 12 = 24
3500 = C × [1 - (1/1.0140833333)24]/0.0140833333
=> C = 172.88

slide 55

Question 41

Suppose you deposit $50 a month into an account that has an APR of 9%, based on monthly compounding.

How much will you have in the account in 35 years?

Answer 41

Monthly rate = 0.09/12 = 0.0075
Number of months = 35 × 12 = 420
=> FV = $50 × [1.0075420 – 1]/0.0075 = $147,089.22

Question 42

You need $15,000 in 3 years for a new car.
If you can deposit money into an account that pays an APR of 5.5% based on daily compounding, how much would you need to deposit?

Answer 42

Daily rate =0.055/365 = 0.00015068493

Number of days = 3 × 365 = 1095

=> PV = $15,000/(1.00015068493)1095= $12,718.56

Question 43

What is the effective annual rate of 7% compounded continuously?

Answer 43

EAR = e0.07 – 1 = 0.0725 or 7.25%

Question 44

WHat is the reward to risk ratio

Answer 44

The risk-reward ratio is a mathematical calculation used by investors to measure the expected gains of a given investment against the risk of loss.
