1. What is the 29.99% Credit Card Interest Calculator?

This calculator estimates the monthly interest you'll pay on credit card debt with a 29.99% Annual Percentage Rate (APR). It helps you understand how much of your payment goes toward interest versus principal.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( P \) — Principal balance (current amount owed)
• \( 0.2999 \) — 29.99% APR expressed as decimal
• \( 12 \) — Number of months in a year
• \( I \) — Monthly interest charge

Explanation: The APR is divided by 12 to get the monthly rate, then multiplied by the principal balance to calculate the monthly interest charge.

3. Importance of Interest Calculation

Details: Understanding your monthly interest helps with budgeting and demonstrates how high-interest debt can quickly accumulate if only minimum payments are made.

4. Using the Calculator

Tips: Enter your current credit card balance (principal). The calculator will show your estimated monthly interest at 29.99% APR.
