ROI is a simple return measure, not an annual rate
Basic ROI equals gain or loss divided by initial cost. Include relevant fees and cash flows when defining both values. ROI does not account for how long the investment was held.
For annualised comparison use the CAGR calculator; for irregular dated cash flows use the XIRR calculator.
