ID: 1249851 • Letter: 1

Question


1. Future Value -- If you deposit $10,000 in a bank account that pays 10 percent interest annually, how much would be in your account after 5 years?









2. Present Value -- What is the present value of a security that will pay $5,000 in 20 years if securities of equal risk pay 7 percent annually?









3. Find the Required Interest Rate -- Your parents will retire in 18 years. They currently have $250,000 and they think they will need $1,000,000 at retirement. What annual interest rate must they earn to reach their goal, assuming they don’t save any additional funds?









4. If you invest $2,000 a year in a retirement account, how much would you have:

?a.?In 5 years at 6 percent?
?b.?In 20 years at 10 percent?
?c.?In 40 years at 12 percent?

  
5. What is the present value of:

?a.?$9,000 in 7 years at 8 percent?
?b.?$20,000 in 5 years at 10 percent?
?c.?$10,000 in 25 years at 6 percent?

Explanation / Answer

1.      Future Value -- If you deposit $10,000 in a bank account that pays 10 percent interest annually, how much would be in your account after 5 years?


To find Future Value (F) given Present Value (P), we can use the factor tables at the end of the textbook or do a manual calculation.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

F = P(1+i)n or F = P( F/P, i,n)

F = P( F/P, i,n)

   = $10,000(F/P, 10, 5)

=$10,000 * 1.611

= $16,110

Thus, the future value is $16,110.

2. Present Value -- What is the present value of a security that will pay $5,000 in 20 years if securities of equal risk pay 7 percent annually?

To find Present Value (P)given Future Value (F), we can use the factor tables at the end of the textbook or do a manual calculation.

P = F(1+i)%u2013n or P = F( P/F, i,n)

P = F( P/F, i,n)

   = $5,000(P/F, 7, 20)

=$5,000 * 0.2584

= $1,292

Thus, the Present Value is $1,292.

3. Find the Required Interest Rate -- Your parents will retire in 18 years. They currently have $250,000 and they think they will need $1,000,000 at retirement. What annual interest rate must they earn to reach their goal, assuming they don%u2019t save any additional funds?


Present value = $250,000

Future value = $1,000,000

N= 18 years and interest rate is calculated by the following expression.


F = P(1+i)n

(1+i)n = F/P

1+i = (F/P)%u2013n

    i = (F/P)%u2013n %u20131

      = ($1,000,000/ $250,000)%u201318 %u20131

      = 4%u201318%u20131

      = 1.08%u20131

     = 0.08 or 8% in percent terms.

Thus, the interest rate is 8%

4. If you invest $2,000 a year in a retirement account, how much would you have:

a) In 5 years at 6 percent?

F = P( F/P, i,n)

   = $2,000(F/P, 6, 5)

=$2,000 * 1.338

= $2,676

Thus, the future value is $2,676.


b) In 20 years at 10 percent?

F = P( F/P, i,n)

   = $2,000(F/P, 10, 20)

=$2,000 * 6.728

= $13,456

Thus, the future value is $13,456.


c.) In 40 years at 12 percent?

F = P( F/P, i,n)

   = $2,000(F/P, 12, 40)

=$2,000 * 93.051

= $186,102

Thus, the future value is $186,102.

-------------------------------------------------------------------------------------------------
5. What is the present value of:

a.)$9,000 in 7 years at 8 percent?

P = F( P/F, i,n)

P = F( P/F, i,n)

   = $9,000(P/F, 8, 7)

=$9,000 * 0.5835

= $5,251.5

Thus, the Present Value is $5,251.5.


b) .$20,000 in 5 years at 10 percent?

P = F( P/F, i,n)

   = $20,000(P/F, 10, 5)

=$20,000 * 0.6209

= $12,418

Thus, the Present Value is $12,418.


c.) $10,000 in 25 years at 6 percent?

P = F( P/F, i,n)

   = $10,000(P/F, 6,25)

=$10,000 * 0.2330

= $2,330

Thus, the Present Value is $2,330.
