💳 How Credit Card Interest Works

Credit card interest is calculated based on your Annual Percentage Rate (APR) and your current balance. When you carry a balance from month to month, interest charges are added — and they can grow fast. The higher your APR and the longer you take to pay off your card, the more you’ll pay in interest over time.

That’s why it’s important to understand how long it will take to pay off your card and how much it will really cost you.
