What this tool does
Total return tells you how much you made; the annualised rate tells you how fast. A 35 % gain is excellent over one year and modest over ten, which is why the two figures are shown together — the second one is the compound annual growth rate.
Formula
ROI = (gain − cost) ÷ cost × 100
