This week we learned about the Modified Internal Rate on Return (MIRR) and its comparisons to the standard IRR. The article I researched stated the MIRR is an improvement over the standard IRR as multiple IRR is eliminated and addresses reinvestment rate issue and generates outcomes. The accuracy of forecasting tends to be higher with MIRR as it projects cash flow being reinvested at the cost of capital. Using the capital inflow adjusted with present value WACC provides a more accurate forecast and is preferred by many mangers. Difference Between IRR and MIRR (with Comparison Chart)- Key Differences
