1. What is Compound Interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. For credit card debt, it means you pay interest not only on the original amount borrowed but also on any interest that has been added to your balance.

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

Explanation: The formula calculates how much your debt will grow over time with compound interest, which is particularly important for understanding credit card debt accumulation.

3. Importance of Understanding Compound Interest

Details: Understanding compound interest is crucial for managing credit card debt. It demonstrates how small balances can grow significantly over time if not paid off, highlighting the importance of paying more than the minimum payment.

4. Using the Calculator

Tips: Enter the principal amount (current balance), annual interest rate (APR), compounding frequency (typically monthly for credit cards), and time period. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How often do credit cards compound interest?
A: Most credit cards compound interest daily, but the interest is typically added to your balance monthly.

Q2: What's the difference between APR and interest rate?
A: APR (Annual Percentage Rate) includes both the interest rate and any additional fees, providing a more complete picture of borrowing costs.

Q3: How can I reduce compound interest on credit card debt?
A: Pay more than the minimum payment, make payments more frequently, or consider transferring balances to a lower-interest card.

Q4: Does making minimum payments avoid compound interest?
A: No, making only minimum payments will result in paying significant compound interest over time as your balance decreases slowly.

Q5: How does compound interest work in favor of savers?
A: The same principle applies to savings - your money earns interest on both the principal and accumulated interest, helping your savings grow faster over time.
