Frequently asked questions
What is the difference between ROI and CAGR?
ROI is the total percentage return over the whole period. CAGR is the equivalent smooth annual rate, which lets you compare investments held for different lengths of time.
Is the holding period required?
No. Leave it blank (or zero) for total ROI only; add years to also see the annualized return.
