Recall from Chapter 5 that the IRR is defined as the discount rate for which the NPV equals zero. It is the compound rate of return that you get from a series of cash flows.
Here are the two decision rules for using the IRR in capital budgeting.
The IRR rule for deciding whether or not a specific investment is worthwhile: Suppose we are considering a project that has cash flows CF0, CF1, CF2, . . . , CFN . IRR is an interest rate such that
CF0 + CF1
(1 + IRR)
+ CF2
(1 + IRR)2
+ ·· ·+ CFN
(1 + IRR)N
= CF0 +
N
t=1
CFt
(1 + k)t
= 0
Rule: If the appropriate discount rate for a project is r, you should accept the project if its
IRR > r and reject it if its IRR < r.
EXCEL NOTE
EXCEL’S NPV FUNCTION VERSUS THE FINANCE
DEFINITION OF NPV
We reiterate our Excel note from Chapter 5 (p. 94): Excel’s NPV function computes the present value of future cash flows; this does not correspond to the finance notion of NPV, which includes the initial cash flow. To calculate the finance NPV concept in the spreadsheet, we have to include the initial cash flow. Hence, in cell B12, the NPV is calculated as
NPV($B$2,B6:B10)B5 and in cell C12 the calculation is NPV($B$2,C6:C10)C5.
Suppose we apply the NPV criterion to projects A and B:
