Understand Credit Card Interest Calculation
Understanding how credit card interest is calculated is crucial for managing your finances effectively. Credit card interest can significantly impact your overall debt, and knowing how it works can help you make better financial decisions.

Understanding APR (Annual Percentage Rate)
APR is the yearly interest rate you'll pay on your credit card balance. However, credit card companies typically divide this rate by 365 to calculate your daily periodic rate, which is then applied to your daily balance.
Understanding Credit Card Interest: The Hidden Costs of Revolving Credit
Many credit card users assume they will be charged interest only on ₹500 for 19 days—the period before the next statement is generated. However, the larger interest component actually stems from the ₹1,000 that remained unpaid for the first 41 days. This means there is no interest-free period, a crucial detail that many customers overlook. Banks classify such users as "Revolvers", applying interest on transactions from the moment they are made.
To avoid high credit card interest rates and maximize your interest-free period, always aim to pay your total outstanding balance on time. Understanding how banks calculate interest can help you manage your finances smarter and save more.
