ROI Calculator Guide: Maximizing Your Investment Returns
Return on Investment (ROI) is the most fundamental metric for evaluating the profitability of any investment. Whether you're a business owner assessing marketing campaigns, a real estate investor comparing properties, or an individual evaluating stock portfolios, understanding ROI is essential for making informed financial decisions.
What is ROI?
ROI measures the gain or loss generated on an investment relative to the amount of money invested. It's expressed as a percentage and calculated using the formula:
ROI = (Net Profit / Cost of Investment) × 100

2. Forgetting Hidden Costs
Include all expenses:
3. Comparing Unlike Investments
Consider risk levels when comparing ROI. A 15% return on a stable bond is very different from 15% on a volatile cryptocurrency.
4. Short-Term Focus
Don't judge investments solely on immediate returns. Some investments need time to mature.
Interpreting Your ROI Results

Your investment gained value. Higher percentages indicate better performance.
