Frequently Asked Questions

What is XIRR?

XIRR stands for Extended Internal Rate of Return. It is used to calculate the annualized return on investments where cash flows happen at irregular intervals.

When should I use XIRR instead of CAGR?

Use CAGR for a single investment held over a period of time. Use XIRR when you make multiple investments or withdrawals at different dates.

How does inflation affect purchasing power?

Inflation decreases the purchasing power of money over time, meaning the same amount of money will buy fewer goods and services in the future.

Can XIRR handle investments made on different dates?

Yes, XIRR is specifically designed to calculate returns for cash flows that occur on various, irregular dates.

What information is required to calculate XIRR?

You need a series of cash flows (amounts invested or withdrawn) and their corresponding exact dates.
