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 the principal balance you carry from month to month.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest charge
• \( P \) — Principal balance (current amount owed)
• \( R \) — Monthly interest rate (APR ÷ 12, expressed as decimal)

Explanation: The formula calculates how much interest accrues on your balance each month based on your card's APR.

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with debt repayment planning, comparing credit cards, and avoiding excessive interest charges by paying more than the minimum payment.

4. Using the Calculator

Tips: Enter your current credit card balance and the card's APR. The calculator will show how much interest you'll be charged for that month if you don't pay the balance in full.

5. Frequently Asked Questions (FAQ)

Q1: How is APR different from interest rate?
A: APR includes both the interest rate and any fees, giving a more complete picture of borrowing costs.

Q2: When is interest charged on credit cards?
A: Interest is typically charged when you carry a balance past the grace period (usually 21-25 days after statement closing).

Q3: How can I reduce my interest charges?
A: Pay your balance in full each month, make payments early in the billing cycle, or consider balance transfer cards with lower rates.

Q4: Does this calculator account for daily compounding?
A: This shows simple monthly interest. Actual credit cards typically use daily compounding, which would result in slightly higher charges.

Q5: 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 those above 25% are high.
