How it works
ROI = (final value − amount invested) ÷ amount invested × 100. Because a 45% gain over 3 years isn't the same as 45% in one year, the annualized ROI (compound annual growth rate) = (final ÷ invested)^(1 ÷ years) − 1.
FAQ
Does ROI include risk or inflation?
No. Compare it with inflation and with what a safer investment would have returned.
