Internal Rate of Return (annualized yield rate) is a rate which an investment will return over the estimated period of ownership. It is in fact the discount rate that produces NPV of zero and profitability index of 1.0. There are a few setbacks when using IRR, such as dual IRR in certain cases or problems with negative cash flows in the future.
