MIRR - Modified Internal Rate of Return

The modified internal rate of return (MIRR) is a financial metric that adjusts the internal rate of return (IRR) to account for a different cost of capital and reinvestment rate. Similar behavior and usage to the MIRR function in Excel.

The MIRR assumes that positive cash flows are reinvested at a reinvestment rate, and any negative cash flows are financed at the cost of capital.

Arguments

• cash_flows - A slice of Decimal values representing the cash flows of the investment
• finance_rate - The cost of capital (interest rate) for financing
• reinvest_rate - The reinvestment rate for positive cash flows

Returns

• The modified internal rate of return (MIRR)

Example

• Cash flows of $-100, $50, $40, $30, $20, finance rate of 0.1, reinvestment rate of 0.05

use rust_finprim::rate::mirr;
use rust_decimal_macros::*;

let cash_flows = vec![dec!(-100), dec!(50), dec!(40), dec!(30), dec!(20)];
let finance_rate = dec!(0.1);
let reinvest_rate = dec!(0.05);
mirr(&cash_flows, finance_rate, reinvest_rate);
