14. Since the big promotion and the raise that goes with it finally came through, you have decided to get serious about saving some money. You are going to save $5,000 per year at the end of each of the next 25 years, but are unsure where to invest the money. If you invest the money in certificates of deposit, you forecast that you will earn a 7.5% effective annual rate of return. An alternative is to invest the money in a High Yield bond fund. The fund claims that last year it generated a 14% effective annual rate of return, but notes that past performance may not reflect future returns.

a. Compute the account balance at the end of the twenty-fifth year if you select the certificate of deposit investment alternative.

b. Compute the account balance at the end of the twenty-fifth year if you select the High Yield investment alternative. Assume that the fund earns a 14% annual return.

c. Given the difference in the account balances, why would anyone purchase certificates of deposit?

15. Three years ago you borrowed $30,000 in order to purchase a boat. The lender agreed to a 7 year loan at a 14% annual interest rate. A unique feature of the loan is the requirement that the annual payment of $6,136.64 be made at the beginning of each year. It is the end of the third year and you are about to write a check for the fourth payment. Since this last year was fairly prosperous you have decided to pay off the entire loan balance at this time. How much do you have to pay in order to repay the entire remaining balance on the loan?

16. You have decided to deposit $1,500 per year at the beginning of each of the next 10 years in an account that earns 8% compounded annually. What is the account balance at the end of the tenth year?

1. You deposit $5,000 in an account that earns 12% compounded annually. Compute the account balance at the end of:

a. 1 year

Present value of deposit=PV=$5000

Rate of interest=i=12% per period

Number of periods=n=1 year

Future Value of deposit=FV=?

FV=PV*(1+i)^n=5000*(1+12%)^1=$5600

b. 20 years

Present value of deposit=PV=$5000

Rate of interest=i=12% per period

Number of periods=n=20 years

Future Value of deposit=FV=?

FV=PV*(1+i)^n=5000*(1+12%)^20=$48,231.47

c. 40 years

Present value of deposit=PV=$5000

Rate of interest=i=12% per period

Number of periods=n=40 years

Future Value of deposit=FV=?

FV=PV*(1+i)^n=5000*(1+12%)^40=$465,254.85

2. You deposit $100,000 in an account that earns a 10% annual rate of return. You have decided that at the end of each year you will withdraw the interest that is credited to your account. If you plan on closing the account at the end of the tenth year, how much are you able to withdraw at that point in time?

Since, interest earned during each year is withdrawn, principal amount at the beginning of 10th year will be equal to the initial deposit.

Principal amount at the beginning of 10th year=P=$100000

Rate of interest=i=10%

Number of period=n=1 (10th year)

Interest earned=P*i*n=100000*10%*1=$10,000

Amount available at the end of 10th year=100000+10000=$110000

3. You have the opportunity to deposit $10,000 into one of two accounts. The Optimum account offers to pay 12% compounded annually while the prime account offers to pay 12% compounded monthly. If you plan on leaving the money in the account for 10 years, what will be the difference between the Optimum and Prime account balances at the end of the tenth year?

Optimum Account

Present Value of deposit=PV=$10000

Rate of interest=i=12% per period

Number of periods=n=10

Future Value of deposit=FV=?

FV=PV*(1+i)^n=10000*(1+12%)^10=$31058.48

Prime Account

Present Value of deposit=PV=$10000

Nominal Rate of interest=i=12% per year with monthly compounding

Number of compounding in a year=c=12

Effective Rate of interest=r=(1+(i/c))^c-1=(1+(12%/12))^12-1=12.6825%

Number of periods=n=10

Future Value of deposit=FV=?

FV=PV*(1+r)^n=10000*(1+12.6825%)^10=$33003.86

Difference in balances=33003.86-31058.48=$1945.38

4. If you expect to inherit $50,000 at the end of the 20 years, compute the present value of the inheritance at the following annual interest rates.

a. 6%

Future value of inheritance=FV=$50000

Rate of interest=i=6% per period

Number of periods=n=20

Present Value of inheritance=FV/(1+i)^n=50000/(1+6%)^20=$15,590.24

b. 12%

Future value of inheritance=FV=$50000

Rate of interest=i=12% per period

Number of periods=n=20

Present Value of inheritance=FV/(1+i)^n=50000/(1+12%)^20=$5,183.34

c. 24%

Future value of inheritance=FV=$50000

Rate of interest=i=24% per period

Number of periods=n=20

Present Value of inheritance=FV/(1+i)^n=50000/(1+24%)^20=$676.92

5. If you require a 10% rate of return on the following investment opportunities, which would you prefer--$100,000 today, $250,000 ten years from today, or $12,000 per year at the end of each of the next 20 years?

PV of option 1 i.e. $100,000 ...
