Frequently Asked Questions
What is a good ROI?
It depends on the context. For stocks, 7–10% annually is considered good. For real estate or business investments, expectations vary widely.
Does ROI account for time?
Basic ROI does not factor in time. Annualized ROI or metrics like IRR are used when comparing investments over different durations.
