Creating a simple ROI (Return on Investment) calculator for evaluating potential investments in Tesla can be done using a straightforward formula. The ROI formula is:

[ \text{ROI} = \left( \frac{\text{Net Returns} - \text{Initial Investment}}{\text{Initial Investment}} \right) \times 100 ]

Here's a simple structure for an ROI calculator that you can implement in a web-based format (HTML and JavaScript):

            document.getElementById('result').innerText = "Please enter valid numbers.";
            return;
        }

        const roi = ((netReturns - initialInvestment) / initialInvestment) * 100;
        document.getElementById('result').innerText = `ROI: ${roi.toFixed(2)}%`;
    }

How to Use the Calculator

  1. Initial Investment: Enter the amount of money you plan to invest in Tesla.
  2. Net Returns: Enter the total returns you expect to receive from the investment.
  3. Calculate ROI: Click the "Calculate ROI" button to see the ROI percentage.

Explanation of the Code

  • HTML Structure: The HTML provides a simple form with input fields for the initial investment and net returns, along with a button to trigger the calculation.
  • JavaScript Function: The calculateROI function retrieves the values from the input fields, checks for valid input, and then calculates the ROI using the formula provided. The result is displayed on the page.
  • Styling: Basic CSS is included for better presentation.

You can copy and paste this code into an HTML file and open it in a web browser to use the ROI calculator.
