Frequently asked questions
How is annualized ROI different from the plain ROI percentage?
Plain ROI is just (final − initial) ÷ initial × 100 over the whole period. Annualized ROI spreads that same return evenly across however many years you enter, using ((final ÷ initial)^(1/years) − 1) × 100 — the standard CAGR formula.
Why is the investment period field optional?
Because it's only needed for the annualized figure — leave it blank or at 0 and you'll still get net profit and plain ROI, just without the annualized breakdown.
What if my final value is negative?
Plain ROI still calculates fine, but annualized ROI can't — raising a negative ratio to a fractional power isn't a real number, so the tool shows an explicit error for that figure instead of a wrong result.
