Frequently Asked Questions
Why does total ROI differ from annualized ROI?▾
Total ROI shows the entire gain over the whole period, while CAGR smooths it into an average per-year growth rate. CAGR is the fair way to compare investments held for different lengths of time.
Does ROI account for taxes and fees?▾
Only if you include them in the numbers you enter. Use the net amount actually invested and the net final value after fees and taxes for an accurate picture.
