1. What is Credit Card Interest Calculation?

The credit card interest calculation estimates the interest charged on outstanding credit card balances in Canada. It helps consumers understand how much interest they will pay based on their average daily balance, annual interest rate, and billing cycle length.

2. How Does the Calculator Work?

The calculator uses the standard interest formula:

Where:

• \( ADB \) — Average Daily Balance (currency units)
• \( R \) — Annual Interest Rate (%)
• \( D \) — Number of Days in Billing Cycle (days)

Explanation: The formula calculates daily interest by converting the annual rate to a daily rate (divided by 365 days) and multiplies by the number of days in the billing cycle.

3. Importance of Interest Calculation

Details: Understanding credit card interest helps consumers make informed financial decisions, manage debt effectively, and avoid unnecessary interest charges by paying balances in full each month.

4. Using the Calculator

Tips: Enter your average daily balance in dollars, annual interest rate as a percentage, and the number of days in your billing cycle. All values must be positive numbers.
