Frequently asked questions

What is the difference between ROI and annualized return?

ROI is the total gain over the whole period. The annualized return is the steady yearly rate that would give the same result, so investments held for different lengths of time can be compared.

What is the formula?

ROI = (amount back − amount invested) / amount invested × 100. Getting 1,300 back from 1,000 is a 30% ROI.

Should income from the investment be included?

Yes. Dividends, interest or rent the investment paid are part of what you got back.
