Frequently Asked Questions
- What's the difference between ROI and CAGR?
- ROI is the total percentage gain over the whole period. CAGR (compound annual growth rate) expresses that as a smoothed per-year rate, which makes investments of different lengths comparable.
- Can ROI be negative?
- Yes. If the final value is less than the initial investment, the ROI and profit are negative — shown in red.
