1. What is the Credit Card Interest Formula?

The credit card interest formula calculates how much interest you'll pay each month on your credit card balance. It's based on your principal balance and annual percentage rate (APR), with the result converted to Canadian dollars using the current exchange rate.

2. How Does the Calculator Work?

The calculator uses the credit card interest formula:

Where:

• \( I \) — Monthly interest (USD)
• \( P \) — Principal balance (USD)
• \( R \) — Monthly interest rate (APR / 12, as a decimal)

Explanation: The formula calculates monthly interest by converting the annual rate to a monthly rate and applying it to your current balance. The result is then converted to CAD using the exchange rate you provide.

3. Importance of Interest Calculation

Details: Understanding how much interest you're paying helps with financial planning and debt management. High interest payments can significantly increase your total debt over time.

4. Using the Calculator

Tips: Enter your current credit card balance in USD, your APR (found in your credit card agreement), and the current USD to CAD exchange rate. Default exchange rate is set to 1.35 CAD per USD.

Q3: How can I reduce my interest payments?
