It is important to note that interest or finance charges on credit cards are compounded daily. This means card issuers calculate finance charges on the daily outstanding balance. This is also one of the main reasons why a credit card overdue quickly escalates. Here is how finance charges are calculated:
Finance Charge = Outstanding Amount × Daily Interest Rate × Number of Days
Here, Daily Interest Rate = Monthly Interest Rate ÷ Number of Days in the Month
Let’s understand this with an example.
Suppose:
- Outstanding Amount: Rs. 30,000
- Monthly Interest Rate: 3.5%
- Payment Made: Rs. 10,000
- Remaining Balance: Rs. 20,000
- Days Outstanding: 30 days
- Monthly Finance Charge: Rs. 20,000 × 3.5% = Rs. 700
Therefore, the cardholder will have to pay an additional Rs. 700 as finance charges, apart from the outstanding balance.
Note: When you have any unpaid balance on your credit card, new transactions you make are not eligible for the interest-free period. This means, in addition to the outstanding dues, you will pay interest on every new purchase from the first day, again leading to quick escalation of your penalties.
