IRR() returns the aggregated internal rate of return for a series of cash flows represented by the numbers in the expression iterated over a number of records as defined by a group by clause.
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.The function needs at least one positive and one negative value to calculate.
