Annualized return (CAGR)

ROI% = (Final + Withdrawals − Initial − Contributions) ÷ (Initial + Contributions). CAGR is only shown when contributions and withdrawals are zero (no mid-period flows).

FAQ

How is ROI calculated here?

We net cash flows: ROI% = (Final + Withdrawals − Initial − Contributions) ÷ (Initial + Contributions) × 100.

Why doesn’t CAGR show sometimes?

Annualized return (CAGR) assumes no cash flows during the period. If contributions or withdrawals occurred, timing matters, so we hide CAGR to avoid misleading results.

Does this include fees or taxes?

No. Enter them inside “Withdrawals” if you want to net them out of the result.
