Annualized ROI

Note: Annualized ROI is the constant annual rate of return that would yield the same total ROI over the specified duration. Calculations involving additional contributions or withdrawals assume these transactions occurred evenly or do not precisely model the timing of cash flows for annualization, providing an estimated annualized return. For highly irregular cash flows, more advanced methods like IRR or TWRR might be needed for precise analysis.
