**MIRR( values(), **

*finance_rate*

*reinvest_rate*)The **MIRR** function has these named arguments:

Part | Description |

| Required. Array of |

| Required. |

| Required. |

**Remarks**

The modified internal rate of return is the internal rate of return when payments and receipts are financed at different rates. The **MIRR** function takes into account both the cost of the investment (** finance_rate**) and the interest rate received on reinvestment of cash (

**).**

*reinvest_rate*The ** finance_rate** and

**arguments are percentages expressed as decimal values. For example, 12 percent is expressed as 0.12.**

*reinvest_rate*The **MIRR** function uses the order of values within the array to interpret the order of payments and receipts. Be sure to enter your payment and receipt values in the correct sequence.

This example uses the **MIRR** function to return the modified internal rate of return for a series of cash flows contained in the array Values(). LoanAPR represents the financing interest, and InvAPR represents the interest rate received on reinvestment.
