| IRR. Returns the internal rate of return for a series of cash flows represented by the numbers in values. These cash flows do not have to be even, as they would be for an annuity. However, the cash flows must occur at regular intervals, such as monthly or annually. The internal rate of return is the interest rate received for an investment consisting of payments (negative values) and income (positive values) that occur at regular periods. Excel Function: IRR(values[,guess]) return: float|string param: mixed $values An array or a reference to cells that contain numbers for which you want param: mixed $guess A number that you guess is close to the result of IRR |
| modifiedRate($values, $financeRate, $reinvestmentRate) X-Ref |
| MIRR. Returns the modified internal rate of return for a series of periodic cash flows. MIRR considers both the cost of the investment and the interest received on reinvestment of cash. Excel Function: MIRR(values,finance_rate, reinvestment_rate) return: float|string Result, or a string containing an error param: mixed $values An array or a reference to cells that contain a series of payments and param: mixed $financeRate The interest rate you pay on the money used in the cash flows param: mixed $reinvestmentRate The interest rate you receive on the cash flows as you reinvest them |
