1. What Is Simple Interest?

Simple interest is a straightforward method of calculating the interest charge on a loan or investment. It is calculated only on the principal amount and does not take compounding into account.

2. How Does The Calculator Work?

The calculator uses the simple interest formula:

\[ Interest = Principal \times \left(\frac{APR}{100}\right) \times Time \]

Where:

\( Principal \) — Initial amount of money (dollars)
\( APR \) — Annual Percentage Rate (%)
\( Time \) — Time period in years

Explanation: This formula calculates the interest earned or paid based on the original principal amount, without considering any accumulated interest from previous periods.

3. Importance Of Interest Calculation

Details: Understanding simple interest calculations is essential for personal finance management, loan comparisons, investment planning, and making informed financial decisions.

4. Using The Calculator

Tips: Enter the principal amount in dollars, APR as a percentage, and time in years. All values must be positive numbers to get accurate results.
