1. What is Monthly APR?

Monthly APR (Annual Percentage Rate) represents the monthly cost of borrowing on a credit card, expressed as a percentage. It helps consumers understand the monthly interest charges they'll incur on their credit card balance.

2. How Does the Calculator Work?

The calculator uses the Monthly APR formula:

Where:

• \( \text{Total Interest} \) — Total interest charged during the billing period
• \( \text{Fees} \) — Any additional fees applied
• \( P \) — Principal amount (original balance)
• \( T \) — Billing period in days (typically 30 days)

Explanation: This formula converts the annual percentage rate to a monthly rate by considering the actual billing period and total finance charges.

3. Importance of Monthly APR Calculation

Details: Understanding monthly APR helps consumers make informed decisions about credit card usage, compare different credit card offers, and better manage their debt repayment strategies.

4. Using the Calculator

Tips: Enter all amounts in currency format, ensure the principal is greater than zero, and input the actual billing period in days (typically 30 days for credit cards).
