XIRR calculators are highly accurate for determining annualized returns on investments with irregular cash flows (e.g., SIPs), often precise to within 0.000001% in tools like Excel. They are superior to CAGR for portfolios with multiple, uneven transactions because they account for the exact timing of each cash flow based on a 365-day year.

How accurate is XIRR?

Yes, XIRR is better than CAGR for SIPs. That's because CAGR only works for one-time lump sum investments, while XIRR factors in multiple investment dates and amounts. It gives a more accurate return rate when you invest in parts over time, like through SIP.

Is XIRR more accurate than IRR?

Together, they help investors assess performance from both a simple and time-sensitive perspective.
