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) set by your credit card issuer.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest charge ($)
• \( P \) — 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 APR.

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with budgeting and demonstrates how carrying a balance can become expensive over time.

4. Using the Calculator

Tips: Enter your current credit card balance and 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 your card's billing cycle and when payments are made.

Q2: How can I reduce my interest payments?
A: Pay your balance in full each month, or make larger payments to reduce the principal faster.

Q3: What's a typical credit card APR?
A: Rates vary but typically range from 15% to 25% for most consumer cards.

Q4: Does this include compound interest?

Q5: Why is my interest higher than this calculation?
A: Your card may have fees, penalties, or use daily compounding which increases total interest.
