Calculates the modified internal rate of return for a series of periodic cash flows

Returns a value specifying the modified internal rate of return for a series of periodic cash flows (payments and receipts).

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 (FinanceRate)
and the interest rate received on reinvestment of cash (ReinvestRate).

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

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.

Internal rate

Value Array

Array of Double specifying cash-flow values. The array must contain at least one negative value (a payment) and one positive value (a receipt).

Finance Rate

The interest rate paid as the cost of financing.

Reinvest Rate

The interest rate received on gains from cash reinvestment.

With the "*RedCrab Calculator*" use the "*MIRR*" function for the
calculation of the modified internal rate.

a=[123,-143,222,-192]

MIRR(a,0.005,0.003)=0.0152
