Frequently Asked Questions
What is ROI?
ROI (Return on Investment) measures the gain or loss generated relative to the amount invested. It is expressed as a percentage: ROI = (Net Profit / Cost of Investment) × 100. A positive ROI means you made money; a negative ROI means you lost money.
What is annualized ROI?
Annualized ROI adjusts the return to a yearly basis, making it easier to compare investments with different holding periods. A 50% ROI over 5 years is very different from 50% ROI in 1 year — annualized ROI accounts for this difference.
