Common questions
How is ROI calculated?
ROI = (amount returned - amount invested) / amount invested, shown as a percentage.
What is annualized ROI and why does it differ from total ROI?
Annualized ROI spreads the total return across the holding period as a per-year rate, so a 50% return over two years is about 22.5% per year — lower than the 50% total.
