1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or loan where interest is added to the principal at regular intervals, allowing interest to be earned on interest. This formula is essential for understanding how savings grow over time in high-interest accounts like those offered by Amex.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + \frac{R}{n})^{(n \times T)} \]

Where:

\( A \) — Maturity amount (USD)
\( P \) — Principal amount (USD)
\( R \) — Annual interest rate (decimal)
\( n \) — Compounding frequency per year
\( T \) — Time period in years

Explanation: The formula accounts for how often interest is compounded, with more frequent compounding resulting in higher returns over time.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest helps investors make informed decisions about savings and investments. It demonstrates how small, regular contributions can grow significantly over time, especially in high-yield savings accounts like those offered by American Express.

4. Using the Calculator

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