XIRR
Definition
Extended Internal Rate of Return — the actual rate of return for a series of cash flows that are not necessarily periodic. Used to calculate real returns on SIPs and investments with irregular cash flows. More accurate than CAGR for SIP investors.
Why is XIRR Important?
In the context of wealth creation and investing in India, XIRR is a fundamental concept. Whether you are investing in mutual funds via SIPs, fixed deposits, or retirement schemes like PPF and NPS, this metric helps evaluate potential returns and risks. The power of compounding and market volatility make it essential to track this indicator for any long-term portfolio.
Investors are encouraged to use specific investment calculators to project the future value of their corpus. Understanding this term enables better asset allocation, inflation protection, and consistent progress toward your ultimate financial goals.
What is XIRR?
XIRR (Extended Internal Rate of Return) calculates the annualized return on investments with multiple cash flows at irregular intervals — making it the most accurate return metric for SIP investments, partial withdrawals, and additional top-ups.
When to Use XIRR vs. CAGR
| Scenario | Use XIRR | Use CAGR |
|---|---|---|
| Monthly SIP | ✓ Best | ✗ Inaccurate |
| Lump sum investment | ✓ Works | ✓ Best (simpler) |
| SIP + lump sum mix | ✓ Best | ✗ Inaccurate |
| Multiple redemptions | ✓ Best | ✗ Cannot handle |
How to Calculate XIRR
XIRR is best calculated using Excel/Google Sheets: =XIRR(cash_flows, dates). Cash outflows (investments) are entered as negative values and inflows (redemptions/current value) as positive. The final row should be the current portfolio value with today's date.
