A Return on Investment (ROI) Calculator is a financial tool designed to help users evaluate the profitability of an investment by calculating the return generated relative to its cost. This calculator is particularly useful for investors, business owners, and anyone looking to assess the financial performance of their investments.

Key Uses of an ROI Calculator:

1. Calculate ROI Percentage:
   Quickly determine the ROI percentage for an investment, allowing users to evaluate how effectively their capital is being utilized.

2. Compare Different Investments:
   Evaluate and compare the ROI of multiple investment options, helping users make informed decisions about where to allocate their resources.

3. Assess Investment Performance:
   Analyze the performance of an investment over time, considering factors such as initial cost, final value, and any associated expenses.

4. Visualize Investment Growth:
   Generate graphs or charts to visualize how an investment has grown over time, providing insights into trends and performance metrics.

5. Estimate Future Returns:
   Allow users to project potential returns on current or future investments based on historical performance and expected market conditions.

Common Input Fields in an ROI Calculator:

• Initial Investment: The total amount of money initially invested.

• Final Value: The total value of the investment at the time of calculation.

• Investment Duration: The length of time the investment was held, typically in months or years (optional).

Output Fields:

• Annualized ROI (if applicable): The average annual return expressed as a percentage, providing a clearer picture of performance over time.

Example Scenario:

Imagine an investor who puts $10,000 into a stock and sells it later for $15,000. The calculator will determine:

• The ROI percentage, which would be 50%.

• The net profit, which would be $5,000.

When to Use It:

• When evaluating potential investment opportunities to understand expected returns.

• During portfolio assessments to analyze the performance of existing investments.
