MIRR Calculator (Modified Internal Rate of Return)
Calculate MIRR from cash flows with separate finance and reinvestment rates. Avoids IRR multiple-root issues.
Use the MIRR Calculator (Modified Internal Rate of Return)
Enter cash flows, finance rate, and reinvestment rate. MIRR is calculated.
Cash flows and rates
Period 0 is outlay. Finance rate discounts outflows; reinvestment rate compounds inflows.
Results
MIRR (annual)
10.34%
MIRR uses finance rate for outflows and reinvestment rate for inflows. Avoids IRR multiple-root issues.
How this calculator works
PV of outflows at finance rate; FV of inflows at reinvestment rate. MIRR = (FV/|PV|) to power 1/n minus 1.
How to interpret your results
Compare MIRR to your cost of capital. Higher MIRR means better project performance under the assumed rates.
FAQs
What is MIRR?▾
Modified IRR. Uses finance rate for outflows and reinvestment rate for inflows, giving a single solution.
Which inputs do I need?▾
Cash flows (period 0 = outlay, 1-4 = inflows), finance rate (%), and reinvestment rate (%).
When would I use this instead of IRR?▾
When IRR has multiple roots or when you want explicit reinvestment assumptions.
