IRR is the interest rate at which the sum of all cash flows equals zero, thus it is useful for comparing one investment to another. In the preceding example, if we substitute 8% with 13.92%, the NPV becomes 0, and your IRR becomes zero. As a result, IRR is defined as the discount rate at which a project's NPV becomes zero.
