INTRODUCTION
The internal rate-of-return (IRR) and adjusted internal rate-of-return (AIRR) methods are members
of a family of economic evaluation methods that provide measures of economic performance of an
investmentovertime.Othermethodsinthisfamilyofevaluationmethodsarelife-cyclecostanalysis,
net benefits and net savings analysis, benefit-to-cost and savings-to-investment ratio analysis, and
payback analysis.
The IRR andAIRR methods are the topic of a single standard practice because they both measure
economic performance as a compound yield on investment.The IRR is the compound rate of interest
that,whenappliedasadiscountratetoaproject’sstreamofdollarbenefitsandcosts,willequatethem.
The AIRR is the overall yield taking into account earnings on receipts reinvested to the end of the
study period.The IRR orAIRR is compared against the investor’s minimum acceptable rate of return
(MARR), and the investment is considered economically attractive if the calculated yield exceeds the
MARR. If an investment entails an initial outlay and a single receipt at the end of the study period,
there is no difference between the IRR and the AIRR. But if cash flows occur over multiple time
periods, the two will normally be different. This arises because theAIRR includes in its measure the
return on reinvestment of receipts, whereas the IRR does not.
The AIRR is recommended for most applications in which a measure of yield is desired. Caution
is recommended in applying either measure, however, because problems arise under certain
conditions.
