Credit Card Interest Rates

Credit Card Interest Rates by Top Banks

The table showcases the monthly and annual percentage rates (MPR% and APR%) of credit cards offered by top banks like HDFC, SBI, Axis, HSBC, IndusInd, Kotak Mahindra, RBL, and Yes Bank, providing an overview of their varying interest rate ranges.

How are Credit Card Interest Rates Calculated?

Credit card interest rate is calculated as the Annual Percentage Rate (APR) of the charge. It is the interest rate for the whole year rather than a monthly rate. However, while calculating the interest rate for monthly dues, the monthly percentage rate (MPR) will be applied to the transactions. The APR and MPR vary from one bank to another and one card to another. While applying for a credit card, it’s important to know how much APR is being charged on a particular card.

Understanding how interest is charged on your credit card is important to manage your finances effectively. Here's an illustration to explain how your card issuer calculates interest:

1. Full payment by the due date (26 May 2026): No interest charges are applicable.
2. Partial payment before the due date (26 May 2026): Partial payment: Rs. 5,000
   1. Interest charged on Rs.20,000 for 21 days: [(21 x Rs.20,000 x 3% x 12)] / 365 days = Rs.414.24
   2. Interest charged on the Rs.15,000 balance for 15 days: [(15 x Rs.15,000 x 3% x 12)] / 365 days = Rs.221.91
   3. Total interest payable: Rs.414.24 + Rs.221.91 = Rs.636.15
3. Partial payment after the due date (26 May 2026): Partial payment: Rs.5,000
   1. Interest charged on Rs.20,000 for 28 days: [(28 x Rs.20,000 x 3% x 12)] / 365 days = Rs.552.33
   2. Interest charged on the Rs.15,000 balance for 9 days: [(9 x Rs.15,000 x 3% x 12)] / 365 days = Rs.133.15
   3. Total interest payable: Rs.552.33 + Rs.133.15 = Rs.685.48
4. Partial payment after the due date with fresh transactions: Partial payment: Rs.5,000 +Fresh transaction: Rs.2,000
   1. Interest charged on the outstanding balance for 15 days: [(15 x Rs.20,000 x 3% x 12)] / 365 days = Rs.295.89
   2. Interest charged on new outstanding balance with a fresh transaction for 13 days: [(13 x Rs.22,000 x 3% x 12)] / 365 days = Rs.282.08
   3. Interest charged on balance after partial payment for 9 days: [(9 x Rs.17,000 x 3% x 12)] / 365 days = Rs.150.90
   4. Total interest payable: Rs.295.89 + Rs.282.08 + Rs.150.90 = Rs.728.87

Note: This is an illustrative example. The interest rate on a credit card can vary from bank to bank. To know more about the interest rate on your credit card, contact your bank.

When is Interest Charged on Credit Cards?

As mentioned earlier, if you pay the total amount due (TAD) on your credit card before the due date, the interest charges will not be applied. Let’s see the cases when the finance charges are applicable on credit card transactions.

Case: 1 - When you make no credit card payment: Interest is charged by the bank on the total amount due when a monthly credit card payment is entirely skipped. All new transactions also accumulate interest from their respective transaction dates. Charges are applied until all previous dues are paid in full. Timely payment is essential to preserve the interest-free grace period.

Example:

Note: Interest rates vary from bank to bank. This is an illustrative example with the interest rate taken at 3.00% MPR and calculated by the formula: (Number of days counted from the date of transaction x Outstanding Amount x Interest rate per month x 12 months)/365.  

Case: 2 – When you pay only the minimum amount due: If you only pay the minimum amount due, it also triggers interest charges on the remaining balance. Credit card issuers apply these finance charges to unsecured balances. It is advisable to do full repayment for maintaining the interest-free grace period.

Case: 3 – When you pay less than MAD: Finance charges are applied on the entire outstanding amount and all new transactions when a payment less than the minimum amount due is made. Interest-free grace periods are forfeited by the borrower, whereas timely full payment results in zero finance costs.

Case: 4 – When you withdraw cash: If you withdraw cash using your credit card, you are availing the cash advance facility, hence, the withdrawn amount will attract finance charges from the date of withdrawal till the amount is paid back in full.

Case: 5 – When you carry forward outstanding: The bank carries remaining amounts forward to the next billing cycle when the previous month's outstanding is not cleared entirely. In such cases, interest is charged on the outstanding balance and all new transactions based on the repayment amount. Charges are applied until the previous dues are cleared completely. 

What is a Credit Card Interest Free Period?

The interest-free period is the grace window, which typically ranges between 15 to 50 days, during which the bank does not charge interest on your credit card spends. The length of the interest-free period depends on when the purchase is made within the billing cycle and the payment due date. 

Example: 

• A purchase is made on the 18th day of the billing cycle. 

• The billing cycle ends in 30 days, and the payment due date is 22 days after statement generation. 

• Total interest-free period = 12 days remaining in the cycle + 22 days = 34 days 

• No interest is charged if the full amount is paid within this window.

How to Use the Credit Card Interest-Free Period Effectively?

The ways to use credit card interest-free period effectively are mentioned below: 

• Time Your Purchases Smartly: Maximize your grace period by timing larger purchases to coincide with the start of the billing cycle.

• Pay the Full Bill on Time: The interest-free benefit applies only if the entire statement of balance is paid by the due date.  

• Avoid Cash Withdrawals: Debit withdrawals are processed using existing funds but do not incur the high interest rates associated with credit-based cash advances.

• Distribute Spending Across Multiple Cards: If you hold more than one credit card with different billing dates, use them strategically to enjoy longer grace periods while keeping spending under control. 

• Pay in Advance When Close to the Due Date: Online payment modes ensure immediate credit, but physical cheques require submission well before the due date to avoid interest and late fees. Digital transactions provide real-time processing, whereas bank clearing for paper instruments introduces significant delays.

How to Reduce Credit Card Interest Charges? 

Smart usage and timely payments can help you minimise or completely avoid interest costs on your credit card. 

• To avoid interest entirely, pay the full statement balance on or before the due date. 

• Pay as much as possible if full payment is not possible. 

• Avoid cash withdrawals using your credit card 

• Only if the total cost is low, use low-cost or zero-interest EMI offers. 

• Opt for balance transfers only when promotional rates and fees reduce overall interest. 

Types of Credit Card Interest in India

Credit card interest varies based on how the card is used, such as used while purchasing, during cash withdrawals, or debt transfers, making it important to understand each type. 

Purchase (Retail) Interest 

Charged on regular card spends when the full outstanding amount is not paid by the due date. 

• Applies to unpaid purchases after the interest-free period (usually 20–25 days) 

• Specific categories like shopping, dining, and travel are charged. 

• Interest accrues the unpaid balance until fully repaid. 

Cash Advance Interest 

Applies when cash is withdrawn using a credit card and is the costliest form of credit card interest. 

• Interest starts immediately with no grace period. 

• Rates usually range from 2.5% to 3.5% per month (30% to 42% annually). 

• In addition to interest, a one-time cash withdrawal fee is also charged. 

Balance Transfer Interest 

Applies when outstanding dues are shifted from one credit card to another. 

• Often comes with a promotional rate for a limited period. 

• Introductory rates may range from 0% to 1% for a few months. 

• Standard rates (around 3% to 4% per month) apply after the promo period. 

Promotional or Introductory Interest Rate 

A temporary reduced or zero-interest rate offered on select transactions or tenures. 

• Banks commonly offer these features on new cards, EMIs, or specific spends. 

• Valid only for a limited time and subject to terms and conditions. 

• Standard interest rates are applied once the offer period ends.

Why are Credit Card Interest Rates High?

Credit card interest rates are higher because they involve greater risk and additional costs for banks. 

Unsecured Nature of Credit Cards

Credit cards do not require collateral, increasing the risk for lenders. 

• In case of default, no asset backing the credit. 

• Higher risk leads to higher interest rates. 

Cost of Rewards, Benefits and Fraud Protection

Card benefits and security systems add to operational expenses. 

• Advanced fraud detection and payment infrastructure require investment. 

Compounding of Interest

Interest on credit cards grows faster due to compounding. 

• Interest is calculated daily or monthly. 

• The issuer charges interest on both the principal and the accumulated interest. 

• Results in a higher effective interest rate over time.
