About the ROI Calculator
Return on investment divides the net gain by the amount invested. Investing 1,000 that grows to 1,250 is a gain of 250 and a 25% ROI. Simple ROI ignores time, so the annualized figure spreads the return over the years held: 1,000 growing to 1,210 over two years is about 10% per year, not 21% per year, because annualized returns compound. A final value below the investment gives a negative ROI, shown as a loss.
