What is a good ROI?

It depends on the asset class and risk level. For stocks, a long-term average of 8–12% per year is considered reasonable. Real estate returns vary widely by location. Business investments often target 20%+ to justify the risk. Always compare ROI against the opportunity cost — what you'd earn on a safer alternative.

What is the difference between ROI and annualised ROI?

Simple ROI is the total return regardless of how long the investment was held. Annualised ROI (also called CAGR — Compound Annual Growth Rate) expresses that return as a yearly equivalent, making investments of different durations comparable. A 45% ROI over 2 years is roughly equivalent to a 20.3% annual return.
