Reading 5: The Time Value of Money-LOS e, (Part 4)习题精选

2010, following, interpret, border, center

Reading 5: The Time Value of Money

LOS e, (Part 4): Calculate and interpret a series of unequal cash flows.

 

 

 

The following stream of cash flows will occur at the end of the next five years.

Yr 1

-2,000

Yr 2

-3,000

Yr 3

6,000

Yr 4

25,000

Yr 5

30,000

At a discount rate of 12%, the present value of this cash flow stream is closest to:

A)
 $33,004.
B)
 $36,965.
C)
 $58,165.


 

N = 1; I/Y = 12; PMT = 0; FV = -2,000; CPT → PV = -1,785.71.
N = 2; I/Y = 12; PMT = 0; FV = -3,000; CPT → PV = -2,391.58.
N = 3; I/Y = 12; PMT = 0; FV = 6,000; CPT → PV = 4,270.68.
N = 4; I/Y = 12; PMT = 0; FV = 25,000; CPT → PV = 15,887.95.
N = 5; I/Y = 12; PMT = 0; FV = 30,000; CPT → PV = 17,022.81.
Sum the cash flows: $33,004.15.

Note: If you want to use your calculator's NPV function to solve this problem, you need to enter zero as the initial cash flow (CF0). If you enter -2,000 as CF0, all your cash flows will be one period too soon and you will get one of the wrong answers.

Assuming a discount rate of 10%, which stream of annual payments has the highest present value?

A)
    $20       –$5        $20        $110
B)
 –$100    –$100    –$100    $500
C)
    $110      $20       $10         $5


This is an intuition question. The two cash flow streams that contain the $110 payment have the same total cash flow but the correct answer is the one where the $110 occurs earlier. The cash flow stream that has the $500 that occurs four years hence is overwhelmed by the large negative flows that precede it.

Suppose you are going to deposit $1,000 at the start of this year, $1,500 at the start of next year, and $2,000 at the start of the following year in an savings account. How much money will you have at the end of three years if the rate of interest is 10% each year?

A)
 $4,000.00.
B)
 $5,750.00.
C)
 $5,346.00.

Future value of  $1,000 for 3 periods at 10% = 1,331
Future value of $1,500 for 2 periods at 10% = 1,815
Future value of $2,000 for 1 period at 10% = 2,200
        Total = $5,346

N = 3; PV = -$1,000; I/Y = 10%; CPT → FV = $1,331
N = 2; PV = -$1,500; I/Y = 10%; CPT → FV = $1,815
N = 1; PV = -$2,000; I/Y = 10%; CPT → FV = $2,200

What is the total present value of $200 to be received one year from now, $300 to be received 3 years from now, and $600 to be received 5 years from now assuming an interest rate of 5%?

A)
 $919.74.
B)
 $980.89.
C)
 $905.87.


200 / (1.05) + 300 / (1.05)3 + 600 / (1.05)5 = 919.74.
