1. What is Credit Card Interest?

Credit card interest is the amount charged by credit card issuers on outstanding balances. It's calculated based on your annual percentage rate (APR) and principal balance.

2. How Does the Calculator Work?

The calculator uses the credit card interest formula:

Where:

• \( I \) — Monthly interest amount
• \( P \) — Principal balance
• \( R \) — Monthly interest rate (APR ÷ 12)

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

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with budgeting, debt repayment planning, and evaluating the true cost of carrying a balance.

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: How is APR different from interest rate?
A: APR includes both the interest rate and any additional fees, giving a more complete picture of borrowing costs.

Q2: What's a good APR for a credit card?
A: As of 2023, average APRs range from 15-25%. Rates below 15% are considered good, while rates above 25% are high.

Q3: How can I reduce my credit card interest?
A: Pay your balance in full each month, negotiate a lower rate, transfer to a 0% APR card, or pay more than the minimum.

Q4: Does this calculator account for daily compounding?
A: This shows simple monthly interest. Actual charges may be slightly higher due to daily compounding in most cards.

Q5: Why is my interest higher than this calculation?
A: Your card may use daily compounding, or you may have cash advances/purchases with different APRs.
