The MIRR function returns the Modified Internal Rate of Return for a supplied series of periodic cash flows, i.e. a set of values, which includes an initial investment value and a series of net income values.
|values||A range of cells that represents the series of cash flows|
|finance_rate||The interest rate that you pay on the cash flow amounts|
|reinvestment_rate||The interest rate that you receive on the cash flow amounts as they are reinvested|
|3||$3,000||Income (yr 1)|
|4||$5,000||Income (yr 2)|
|5||$1,200||Income (yr 3)|
|6||$4,000||Income (yr 4)|
|7||$3,800||Income (yr 5)|
|8||5.5%||Annual interest rate|
|12||=MIRR(A2:A7,A8,A9)||21.55%||Investments modified rate of return after 5 years|
|13||=MIRR(A2:A5,A8,A9)||10.43%||Modified rate of return after 3 years|
|14||=MIRR(A2:A7,A8,14%)||24.46%||5-year modified rate of return based on a reinvest_rate of 14 percent|
Common Function Error(s)
|Problem||What went wrong|
|#VALUE!||Occurs if any of the supplied arguments are non-numeric values|
|#DIV/0!||Occurs if the supplied values array does not contain at least one negative and at least one positive value|
The Modified Internal Rate of Return (MIRR) indicates the profitability of an investment and therefore is commonly used in business, when choosing between investments. MIRR is calculated as:
- n = number of cash flows in values
- frate = finance_rate
- rrate = reinvest_rate
This calculation uses a schedule of payments (including an initial investment, along with the net income payments), to calculate the compounded return, assuming the Net Present Value of the investment is zero.
The difference between the Modified Internal Rate of Return (MIRR) and the Internal Rate of Return (IRR) is that, in its calculation, the MIRR considers the initial cost of the investment and also the interest received on the reinvestment of cash, whereas the IRR does not consider these.
