Build A Simple Interest Calculator with HTML, CSS & JavaScript

Welcome to ByteWebster's JavaScript projects. In this project, we have developed a Simple Interest Calculator using HTML, CSS, and JavaScript, which you can easily integrate into your web development projects.

This JavaScript Simple Interest Calculator is an online utility tool designed to help you calculate the interest on loans or savings. You can determine the simple interest on the principal amount on a daily, monthly, or yearly basis, making it versatile for various financial calculations.

To use the calculator, follow these steps:

1. Enter the principal amount in the designated field.
2. Input the annual rate of interest as a percentage.
3. Specify the time duration in years for which you want to calculate the interest.
4. Click the "Submit" button to see the results.

Upon submission, the calculator performs the following actions:

• Validates the input values to ensure they are positive numbers.
• Calculates the interest using the formula: Interest = (Principal Amount * Rate * Time) / 100.
• Displays the principal amount, calculated interest, and the total amount (principal + interest).

Additionally, the tool provides real-time feedback for incorrect inputs, ensuring a smooth user experience. If invalid values are entered, a toast notification will alert the user to correct the input.

This Simple Interest Calculator is a practical example of how JavaScript can be used to create interactive and user-friendly web applications. It demonstrates fundamental concepts such as input validation, DOM manipulation, and dynamic content generation.

We hope this tool proves useful in your financial planning and educational endeavors. Feel free to explore, use, and customize it for your specific needs.
