Your guide to return on investment
Return on Investment (ROI) is a simple but powerful metric that measures the profitability of an investment. It tells you how much money you made (or lost) relative to the amount you invested. ROI is expressed as a percentage, making it easy to compare different investments. Whether you're a business owner, investor, or just planning your finances, understanding ROI is essential for making smart decisions.
What is return on investment?
Return on Investment measures the efficiency of an investment. It calculates the return (profit) generated from an investment relative to the cost of that investment. A positive ROI means the investment is profitable. A negative ROI means it lost money. ROI can be used to evaluate investments, projects, marketing campaigns, and more.
The ROI formula
The basic formula for ROI is:
Where:
- Final Value: The total amount you received from the investment.
- Cost of Investment: The total amount you invested (including additional contributions).
For investments held over multiple years, the annualized return is:
ROI comparison across different investments
Here's how different investments compare based on ROI:
| Investment Type | Initial Investment | Final Value | Net Profit | ROI |
|---|---|---|---|---|
| High-Yield Savings | $10,000 | $11,500 | $1,500 | 15% |
| Index Fund (S&P 500) | $10,000 | $15,000 | $5,000 | 50% |
| Growth Stocks | $10,000 | $18,500 | $8,500 | 85% |
| Real Estate | $10,000 | $14,200 | $4,200 | 42% |
| Business Investment | $10,000 | $22,000 | $12,000 | 120% |
Higher ROI doesn't always mean better — it also depends on risk and time. A high ROI with low risk is ideal.
ROI vs Annualized Return
Here's how ROI and Annualized Return compare for the same investment over different time periods:
| Investment Period | Total ROI | Annualized Return | Best For Comparison |
|---|---|---|---|
| 1 Year | 12% | 12% | Both |
| 3 Years | 38% | 11.3% | Annualized |
| 5 Years | 70% | 11.2% | Annualized |
| 10 Years | 180% | 10.9% | Annualized |
| 20 Years | 480% | 9.3% | Annualized |
Annualized return is better for comparing investments with different time periods because it normalizes the return to a per-year basis.

Example: Evaluating a business investment
You invested $50,000 in a small business. Over 3 years, you received $75,000 in total returns. You also contributed an additional $5,000 during the period.
- Initial Investment: $50,000
- Additional Contributions: $5,000
- Final Value: $75,000
- Investment Period: 3 years
Total Invested = $55,000
Net Profit = $75,000 - $55,000 = $20,000
ROI = ($20,000 / $55,000) × 100 = 36.36%
Annualized Return = 10.9%
Result: This investment generated a 36.36% total return with an annualized return of 10.9%. This is a solid investment, especially if it's relatively low-risk.

Common mistakes to avoid

- Forgetting additional costs: Include all costs in your calculation.
- Comparing ROI across different timeframes: Use annualized return for fair comparison.
- Ignoring risk: A high ROI may come with high risk.
