What is XIRR?
← Back to FAQ
XIRR stands for Extended Internal Rate of Return and is a method used to calculate the return on an investment when cash flows occur at irregular intervals. It provides a more accurate measure of performance compared to standard return calculations when timing varies.
XIRR calculates the annual return of an investment while taking into account the exact timing of each cash flow.
In financial analysis, XIRR is widely used to evaluate investments such as portfolios, private equity, or projects where money is invested and withdrawn at different times. Unlike the traditional internal rate of return, which assumes evenly spaced cash flows, XIRR adjusts for the actual dates of each transaction. This makes it particularly useful for real world scenarios where investors add or withdraw funds over time. The result is expressed as an annual percentage, allowing for easy comparison between different investments. However, XIRR relies on assumptions and can sometimes produce misleading results if cash flows are highly irregular or if multiple solutions exist.
Short example:
Suppose an investor invests $1,000 in January, adds $500 in June, and withdraws $2,000 at the end of the year.
XIRR calculates the annual return by considering the exact timing of each transaction.
The result might show a return of 18 percent, reflecting both the amounts and the timing of the cash flows.
