This tool helps you calculate the interest you will earn on your savings over a period of time.

## Interest Calculator

This calculator computes the interest based on the principal amount, the annual interest rate, and the time period in years. The interest is calculated using the simple interest formula:

**Simple Interest Formula:** *Interest = Principal * Rate * Time / 100*

### How to Use This Calculator

- Enter the Principal Amount in the corresponding input field.
- Enter the Annual Interest Rate as a percentage.
- Enter the Time period in years.
- Click the “Calculate” button to see the results, which include the interest earned and the total amount.

### Explanation

The calculator works by taking the three inputs (Principal Amount, Annual Interest Rate, and Time in years) and applying the simple interest formula. The interest is calculated as a percentage of the principal amount over the specified period of time, and then it is added to the principal amount to give the total amount.

### Limitations

This calculator assumes that the interest rate is fixed and that it does not account for compounding interest, fees, or other potential variables that could affect the actual interest earned. It provides a straightforward calculation based on the inputs provided and should be used for estimation purposes only.
