❓ Frequently Asked Questions
ROI (Return on Investment) is a key financial metric for measuring investment efficiency. The formula is: (Total Returns - Investment Cost) / Investment Cost x 100%. For example, investing $100,000 and receiving $150,000 gives an ROI of (150-100)/100 x 100% = 50%. Higher ROI indicates better investment returns.
ROI calculates the total return rate for the entire investment period without considering the time factor. Annualized return compounds and converts the total return rate based on the investment period to get the average annual return rate. For example, earning 50% over 3 years gives an annualized return of approximately 14.5%. Annualized return makes it easier to compare projects with different investment periods.
There is no absolute standard, as different types of investment projects vary greatly. General references: 5-8% annualized return is conservative (bonds/wealth management), 8-15% is growth-oriented (index funds), 15%+ is high-risk (stocks/startups). Over the long term, Buffett's ~20% annualized return is considered world-class.
