1. What is Credit Card Interest?

Credit card interest is the cost of borrowing money on your credit card. It's calculated based on your outstanding balance and the annual percentage rate (APR) of your card.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest ($)
• \( P \) — Principal balance ($)
• \( R \) — Monthly interest rate (APR / 12, as decimal)

Explanation: The formula calculates how much interest you'll pay each month based on your current balance and card's APR.

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with budgeting and shows the true cost of carrying a credit card balance.

4. Using the Calculator

Tips: Enter your current credit card balance and the card's APR. The calculator will show your estimated monthly interest charge.

5. Frequently Asked Questions (FAQ)

Q1: Is this the actual interest I'll pay?
A: This is an estimate. Actual interest may vary based on billing cycle, payment timing, and compounding.

Q2: How can I reduce my interest payments?
A: Pay your balance in full each month, negotiate a lower APR, or transfer to a 0% APR card.

Q3: Does this include fees?
A: No, this calculates only interest. Late fees, annual fees, etc. are not included.

Q4: What if I make partial payments?
A: The calculator assumes no payments. Making payments reduces principal and thus interest.

Q5: How often is interest calculated?
A: Most cards calculate daily (then charge monthly) using your average daily balance.
