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 amount ($)
• \( P \) — 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 (found on your statement). 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. Your 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 lower-rate card.

Q3: What's a typical credit card APR?
A: Rates vary but typically range from 15% to 25% APR depending on creditworthiness and card type.

Q4: Does this include fees?
A: No, this calculates interest only. Late fees, annual fees, etc. are additional.

Q5: How is daily interest calculated?
A: Some cards use daily periodic rate (APR ÷ 365) applied to daily balances, which would result in slightly higher interest.
