Question 1

What is ROI and how is it calculated?

Accepted Answer

ROI (Return on Investment) measures the profitability of an investment as a percentage. It is calculated by dividing the net gain (return minus investment) by the original investment amount, then multiplying by 100. For example, investing $10,000 and receiving $13,000 back gives an ROI of 30%.

Question 2

What is a good ROI for a business investment?

Accepted Answer

A good ROI varies by context. For stock market investments, 7-10% annually is historically average. For business projects, 25%+ annualized is generally considered excellent. Real estate typically targets 8-12%. Always compare ROI against your cost of capital — if your ROI is below your borrowing rate, the investment destroys value.

Question 3

What is the difference between total ROI and annualized ROI?

Accepted Answer

Total ROI shows the overall percentage return regardless of time. Annualized ROI adjusts for time to show the equivalent yearly return. A 50% total ROI over 5 years is only about 8.4% annualized. Annualized ROI is more useful for comparing investments with different time horizons.

Question 4

Does ROI account for risk?

Accepted Answer

No — standard ROI does not factor in risk. A 20% ROI from government bonds is far more impressive than 20% from speculative crypto because the risk profiles differ enormously. For risk-adjusted comparison, use metrics like Sharpe ratio or consider the probability of loss alongside the expected return.

Question 5

How does inflation affect my real ROI?

Accepted Answer

Inflation erodes the purchasing power of your returns. If your ROI is 8% but inflation is 3%, your real ROI is approximately 5%. Always subtract the inflation rate from your nominal ROI to estimate real returns. Use our inflation calculator to see the precise impact.

Question 6

Can ROI be negative?

Accepted Answer

Yes — if your return is less than your investment, ROI is negative, indicating a loss. For example, investing $10,000 and receiving $7,000 back gives an ROI of -30%. Negative ROI means the investment destroyed value.

Question 7

How do I compare ROI across different investments?

Accepted Answer

Always compare using annualized ROI to normalize for different time periods. Also consider risk, liquidity, tax implications, and time commitment. A 15% annualized ROI from a hands-off index fund may be better than 20% from a business that requires 60 hours per week of your time.
