How to use MIRR function Excel?

MIRR Excel function is very simple and easy to use. Let’s understand the working of this function by considering some simple MIRR formula examples.

MIRR Function Excel Example #1

Consider an initial loan amount of 25,000 as initial investment amount (loan amount) with an interest rate of 5% yearly and you have earned an interest rate of 8% from the reinvested income. In MIRR excel the loan amount or initial investment amount is always considered as (-ve) value.

Below are the table shows the details of income after regular interval of time. Considering the cash flow of income for 1^st, 2^nd, 3^rd, 4^th, and 5^th years are as follows: 10,911, 14,716, 19,635, 18,700, and 18,477.

Now calculate MIRR in Excel (Modified internal return rate) after 2 years:

=MIRR(B4:B6,B10,B11) and output MIRR is 3%.

Similarly, calculate MIRR in Excel (Modified internal rate of return) after 3 and 5 years:

MIRR after three years will be =MIRR(B4: B7, B10, B11) and output is 25%.

MIRR after five years will be=MIRR(B4: B9, B10, B11) and output is 31%.

MIRR Function Excel Example #2

Consider an initial loan amount of 10,000 as an initial investment with an interest rate of 5% yearly and you have earned an interest rate of 8% from the reinvested income.

Below are the table shows the details of income after regular interval. Considering the cash flow of income for 1^st, 2^nd, 3^rd, 4^th, and 5^th years are as follows: 7,505, 5,338, 9,465, 5,679, and 6,004.

Now calculate MIRR in Excel after 2 years:

=MIRR(B15:B17,B21,B22)and output MIRR is 16%.

Similarly, calculate MIRR in Excel after 3 and 5 years:

MIRR after three years will be =MIRR(B15: B18, B21, B22) and output is 34%.

MIRR after five years will be =MIRR(B15:B20,B21,B22) and output is 32%.

Things to remember about the MIRR Function Excel

Loan amount is always considered as negative value.
The modified internal return rate is always calculated on variable cash flow after regular interval.
Error handling:

#DIV/0!: MIRR excel will return #DIV/0! Exception when the supplied error does not contain at least one negative value of one positive value.

#VALUE!: MIRR excel will return this kind of exception when any of the supplied value is non-numeric.
