Question
13. NPV versus IRR. Here are the cash flows for two mutually exclusive projects: (LO8-1 and
LO8-2)
Project C0 C1 C2 C3
A -$20,000 +$8,000 +$8,000 +$ 8,000
B - 20,000 0 0 + 25,000
a. At what interest rates would you prefer project A to B? ( Hint: Try drawing the NPV profile
of each project.) . What is the IRR of each project?
Please provide a formula not in an excel sheet
Explanation / Answer
a. We will prefer Project at the Higher Interest rate and Project B at the Lower Interest rate. Example:
At 4% interest rate, the NAV of Project A = 2.775 * 8000 - 20000 = $2200 and of Project B = 0.889 * 25000 - 20000 = $2225, Project B is preferred.
At 6% interest rate, the NAV of Project A = 2.673 * 8000 - 20000 = $1384 and of Project B = 0.840 * 25000 - 20000 = $1000, Project A is preferred.
b. IRR of Project A = 4% + (22200 - 20000) / (22200 - 21384) * (6 - 4)% = 9.39%
IRR of Project B = 4% + (22225 - 20000) / (22225 - 21000) * (6 - 4)% = 7.63%
