IRR calculations are quite difficult when the number of cash flows exceed 5, however for number of cash flows limited to a count of 3 one may use the Quadratic formula to find the two IRR solutions. Here the cash flows take the form of a Quadratic equation that is solved to find the two roots of the 2nd degree polynomial. Here me Abraham A. will take you on a guided lesson that will show the various steps required in solving the quadratic equation to find the two internal rate of return values.

Please go ahead and download InvAppraisal calculator that offers 10 financial functions to analyze investments including one to find internal rate of return. This IRR calculator allows you to find the interest rate on an investment, it is programmed using numerical methods that find the IRR with iterative calculations. This is unlike using the Quadratic formula to find the two IRR values. Here the calculator makes an initial guess of 10% and then to perform iterative calculations to find one or more IRR values. Have a look at the screen shot of this robust, feature rich and easy to use calculator that is shown below.

The IRR - internal rate of return is used by an analyst to help find an investor's return on investment. The investor would be willing to only invest money if there gains are expected or else the investment will be discarded. However finding an internal rate of return is not such an easy task when the number of cash flows exceed the count of three. For cash flows with number of cash flows of three, the IRR may be found using the Quadratic formula. The series of cash flows in the investment form a polynomial of degree 2, thus allowing us to utilize the quadratic equation. The three cash flows of the investments make up the coefficients of the quadratic equation and one can readily solve this equation using the quadratic formula to find the internal rate of return. Here I present you with an IRR document as as Word file that will explain the IRR calculation using the quadratic formula. It will begin by showing you how the series of cash flows are used to define the quadratic equation and from there to use the quadratic formule for find one or two IRR values.
