fin.modified-irr Calculator
Calculates Modified IRR (MIRR) using separate reinvestment and finance rates, correcting the IRR assumption that cash flows reinvest at the IRR itself. MIRR is more realistic than IRR when the project's cash flows can't actually be reinvested at the IRR rate.
Inputs
Initial Investment
Upfront cost — the negative cash flow at time zero in NPV/IRR analysis.
Annual Cash Flow
Total net cash received or paid in one year. Used in payback period and simple ROI calculations.
Finance Rate Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Reinvestment Rate Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Years
Reference formula or conversion factor shown for context.
Results
MIRR
IRR (internal rate of return) -- the annualised return rate at which net present value equals zero. If IRR exceeds the hurdle rate, the investment adds value.
terminal value (FV of CFs)
The computed numeric or monetary value.
IRR comparison
IRR (internal rate of return) -- the annualised return rate at which net present value equals zero. If IRR exceeds the hurdle rate, the investment adds value.
finance rate
The value at the specified point or condition.
reinvestment rate
The value at the specified point or condition.
MIRR = (FV/PV)^(1/n) - 1
IRR (internal rate of return) -- the annualised return rate at which net present value equals zero. If IRR exceeds the hurdle rate, the investment adds value.
