FAQ
Q. What is a good ROI?
It varies by industry and investment type, but generally an annual ROI above 10% is considered favorable. The long-term average stock market return is around 7–10% per year.
Q. What is the difference between ROI and ROAS?
ROI measures net profit relative to total investment cost, while ROAS (Return on Ad Spend) measures revenue relative to advertising spend. ROAS is primarily used to gauge marketing efficiency.
Q. What are the limitations of ROI?
ROI does not account for the time period of an investment. A 20% ROI over one year is very different from 20% over five years. Use annualized ROI or IRR for time-adjusted comparisons.
