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 principal balance and annual percentage rate (APR), typically compounded monthly.

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 ÷ 100)

Explanation: This calculates the monthly interest charge before any payments or additional charges are applied.

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with budgeting, comparing credit cards, and making informed decisions about paying down balances.

4. Using the Calculator

Tips: Enter your current balance and annual percentage rate (APR). The calculator will show your estimated monthly interest charge.

5. Frequently Asked Questions (FAQ)

Q2: How can I reduce my interest charges?
A: Pay your balance in full each month, make payments early in the billing cycle, or negotiate a lower APR.

Q3: What's a good APR for a credit card?
A: As of 2023, average APRs range from 15-25%. Rates below 15% are generally considered good.

Q4: Does this include compound interest?
