Given the following cash flows for a capital project, calculate the NPV and IRR. The
required rate of return is 8 percent.
Year 0 1 2 3 4 5
Cash flow −50,000 15,000 15,000 20,000 10,000 5,000

A $1,905 10.9%
B $1,905 26.0%
C $3,379 10.9% Correct answer- C is correct.

The IRR, found with a financial calculator, is 10.88 percent.
Given the following cash flows for a capital project, calculate its payback period and
discounted payback period. The required rate of return is 8 percent.
Year 0 1 2 3 4 5
Cash flow −50,000 15,000 15,000 20,000 10,000 5,000
The discounted payback period is:
0.16 years longer than the payback period.
0.51 years longer than the payback period.
1.01 years longer than the payback period. Correct answer- C is correct.
Year 0 1 2 3 4 5
Cash flow −50,000 15,000 15,000 20,000 10,000 5,000
Cumulative cash flow −50,000 −35,000 −20,000 0 10,000 15,000
Discounted cash flow −50,000 13,888.89 12,860.08 15,876.64 7,350.30 3,402.92
Cumulative DCF −50,000 −36,111.11 −23,251.03 −7,374.38 −24.09 3,378.83
As the table shows, the cumulative cash flow offsets the initial investment in exactly
three years. The payback period is 3.00 years. The discounted payback period is
between four and five years. The discounted payback period is 4 years plus
, 24.09/3,402.92 = 0.007 of the fifth year cash flow, or 4.007 = 4.01 years. The
discounted payback period is 4.01 − 3.00 = 1.01 years longer than the payback period.
An investment of $100 generates after-tax cash flows of $40 in Year 1, $80 in Year 2,
and $120 in Year 3. The required rate of return is 20 percent. The net present value is
closest to:
$42.22.
$58.33.
$68.52. Correct answer- B is correct.
NPV=∑t=03CFt(1+r)t=−100+401.20+801.202+1201.203=$58.33
An investment of $150,000 is expected to generate an after-tax cash flow of $100,000 in
one year and another $120,000 in two years. The cost of capital is 10 percent. What is
the internal rate of return?
28.39 percent.
28.59 percent.
28.79 percent. Correct answer- C is correct. The IRR can be found using a financial
calculator or with trial and error. Using trial and error, the total PV is equal to zero if the
discount rate is 28.79 percent.
Present Value
Year Cash Flow 28.19% 28.39% 28.59% 28.79%
0 −150,000 −150,000 −150,000 −150,000 −150,000

2 120,000 73,025 72,798 72,572 72,346
Total 1,034 686 338 −8
A more precise IRR of 28.7854 percent has a total PV closer to zero.
Kim Corporation is considering an investment of 750 million won with expected after-tax
cash inflows of 175 million won per year for seven years. The required rate of return is
10 percent. What is the project's:
NPV? IRR?
A 102 million won 14.0%
B 157 million won 23.3%
C 193 million won 10.0% Correct answer- A is correct.
