1. What is Simple Interest?

Simple interest is a method of calculating interest where the interest is computed only on the original principal amount throughout the entire term of the loan or investment. It is commonly used for short-term investments and loans.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

\[ I = P \times \left(\frac{R}{100}\right) \times T \]

Where:

\( I \) — Interest earned (currency units)
\( P \) — Principal amount (currency units)
\( R \) — Annual interest rate (%)
\( T \) — Time period (years)

Explanation: The formula calculates the interest earned by multiplying the principal amount by the annual interest rate (converted to decimal) and the time period in years.

3. Importance of Interest Calculation

Details: Accurate interest calculation is crucial for financial planning, investment decisions, and understanding the cost of borrowing. It helps investors and borrowers make informed financial decisions.

4. Using the Calculator

Tips: Enter the principal amount in currency units, annual interest rate as a percentage, and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest from previous periods.

Q2: Is simple interest commonly used for CD accounts?
A: While some CDs use simple interest, many modern CD accounts use compound interest. Always check the terms of your specific CD account.

Q3: Can time be entered in months instead of years?
