The internal rate of return (IRR): projections, benchmarks and pitfalls
Abstract
Purpose
The purpose of this paper is to discuss the use of the internal rate of return (IRR) as a principal measure of performance of investments and to highlight some of the weaknesses of the IRR in evaluating investments in this way.
Design/methodology/approach
This Education Briefing is an overview of the limitations of the IRR in making capital budgeting decisions. It is illustrated with a number of counter-intuitive examples.
Findings
The advantage of the IRR is that it is, on the surface, a wonderfully simple benchmark. One figure that tells a story. But, the disadvantage is that if used in isolation the IRR can give misleading results when used to assess investment proposals.
Practical implications
The IRR should be used in conjunction with other analyses to appraise projects, so that the user can determine its veracity in the context of other benchmarks. This context is particularly important when assessing investments with unusual cash flows.
Originality/value
This is a review of existing models.
