Cash Flow: Calculate IRRCalculate

In order to find the Internal Rate of Return (IRR) we must attempt to find a Discount Rate that results in a Net Present Value (NPV) of 0. These equations are generally non-linear (hence why a graph is useful) and therefore more than one real root (IRR) is a possibility. (Note that for this very reason, the NPV is far superior to the IRR as an investment appraisal tool).
