Welcome to MC Explains, an investor education series by Moneycontrol and Invesco Mutual Fund. In this video, we break down XIRR (Extended Internal Rate of Return) — the most accurate way to measure returns when you’ve made multiple investments over time, like in an SIP or SWP. Are you tracking your investment returns correctly? If you're using only absolute or annualized return to measure your mutual fund or SIP performance, you may be missing the full picture. Whether you're a mutual fund investor or just starting out, understanding XIRR will help you make smarter investment decisions.
