Frequently Asked Questions
How is ROI calculated?
Subtract the cost from the gain, divide by the cost, and multiply by 100 to express return on investment as a percentage.
What is a good ROI?
It is relative to risk and alternatives; a good ROI beats what you could earn safely elsewhere for comparable risk.
Does ROI account for time?
Basic ROI ignores how long the investment took, so use annualized return or CAGR to compare investments of different lengths.
