XIRR vs CAGR: Which return metric should Indian investors trust?

Last reviewed: 2026-02-28

Direct answer

Use CAGR for single lump-sum investments without intermediate cash flows. Use XIRR for real-world portfolios with multiple buys/sells/SIPs. For decision quality, pair return metric with post-tax outcome checks through LTCG/STCG calculators.

Why this matters

Many investors optimize only gross return. In practice, the better decision is often the one with better after-tax return and cash-flow timing. That is why XIRR + tax planning beats simple percentage comparisons.

Practical workflow

  1. Measure portfolio-level performance using XIRR.
  2. Estimate exit-tax outcomes with LTCG and STCG calculators.
  3. Choose actions based on post-tax, time-adjusted return.
