The Hidden Costs of Credit Cards: Interest & Fees Guide (2026)
While credit cards offer convenience and rewards, they are also the most expensive form of debt in India. With interest rates often exceeding 42% per annum, understanding the "fine print" is essential for your financial health.
1. How Interest is Calculated (The ADB Method)
Most Indian banks (HDFC, SBI, ICICI, etc.) use the Average Daily Balance (ADB) method.
The Critical Rule: If you fail to pay the Total Amount Due by the due date, the interest-free "Grace Period" is completely cancelled. Interest is then back-calculated from the date of the original purchase, not the due date.
The Formula:
Interest Amount = Average Daily Balance × Monthly Interest Rate × 12 × Number Off Days / 365
2. Beware of the "Minimum Amount Due" (MAD) Trap
The "Minimum Amount" is usually just 5% of your total bill. Paying only the MAD is one of the fastest ways to fall into a debt trap.
- The Math: If you owe ₹1,00,000 at 42% p.a. and pay only the minimum, it could take you over 10 years to clear the debt, and you would end up paying nearly ₹2,00,000 in interest alone.
- New Spending: If you haven't paid your previous bill in full, every new purchase you make starts accruing interest from Day 1. There is no grace period for new transactions until the entire previous balance is cleared.

4. 🛡️ 3 Rules to Avoid Credit Card Interest
1.The 100% Rule: Always pay the Total Amount Due, never just the Minimum Amount Due.
2.No Cash Withdrawals: Never use your credit card at an ATM. There is no interest-free period on cash; interest starts the second the money leaves the machine.
3.Auto-Debit: Set up an auto-debit for the "Total Amount Due" from your savings account to ensure you never miss a deadline.
Frequently Asked Questions
What is the minimum payment on a credit card?
The minimum payment is typically 5% of the outstanding balance or ₹200, whichever is higher. Paying only the minimum keeps you debt-free on paper but results in massive interest charges over time. Always aim to pay the full statement balance.
What happens if I miss a credit card payment?
Missing a payment triggers late payment fees (up to ₹1,300), the interest-free grace period is forfeited, interest accrues from the purchase date, and your CIBIL score drops. Consecutive missed payments can also result in card blocking.
Is converting outstanding to EMI a good idea?
Credit card EMI conversion typically charges 12–24% p.a. — much lower than the 36–48% revolving interest. If you can't pay the full outstanding immediately, converting to EMI is almost always better than letting interest compound at the revolving rate.
Does paying minimum due protect CIBIL score?
Paying the minimum due protects you from late payment marks on your CIBIL report. However, having a high credit utilization ratio (balance close to limit) still negatively impacts your score. Pay off as much as possible, not just the minimum.
