Frequently Asked Questions
How is Annualized ROI different?
Total ROI just shows the overall percentage gained. Annualized ROI breaks that gain down into an average yearly growth rate, making it easier to compare investments of different lengths.
Can ROI be negative?
Yes, if the amount returned is less than the amount invested, you will have a negative ROI, representing a financial loss.
