1. What is Simple Interest?

Simple interest is a method of calculating interest where the interest is computed only on the principal amount throughout the entire duration of the investment or loan. It is commonly used for certificates of deposit (CDs) and short-term investments.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

\[ SI = \frac{P \times R \times T}{100} \]

Where:

\( P \) — Principal amount (initial investment)
\( R \) — Annual interest rate (percentage)
\( T \) — Time period in years
\( SI \) — Simple interest earned

Explanation: The formula calculates the interest earned based on the original principal amount without compounding over the specified time period.

3. Importance of Simple Interest Calculation

Details: Understanding simple interest is crucial for financial planning, investment decisions, and comparing different CD options. It helps investors predict their returns accurately for fixed-term investments.

4. Using the Calculator

Tips: Enter the principal amount in dollars, 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 interest 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: Are CDs always calculated with simple interest?
A: Most traditional CDs use simple interest, but some financial institutions may offer compound interest CDs. Always check the terms of your specific CD.

Q3: How often is interest typically paid on CDs?
A: Interest on CDs can be paid monthly, quarterly, semi-annually, or at maturity, depending on the CD terms.

Q4: Can I withdraw my CD before maturity?
A: Early withdrawal from CDs typically incurs penalties, which may reduce or eliminate the interest earned.

Q5: Is simple interest better than compound interest for CDs?
A: Compound interest generally yields higher returns for the same principal, rate, and time period. However, simple interest CDs are simpler to understand and calculate.
