IRR and XIRR are Excel functions that you can use to determine the rate of return on your investment. IRR assumes all the periods in a series of cash flows are equal and doesn’t consider the timing of the cash flows. XIRR is a more versatile function that gives you the flexibility to assign specific dates to each cash flow, making it suitable for cash flow series that occur at irregular intervals. Essentially, the XIRR formula weighs the timing of cash flows and calculates a more accurate return on investment.
