Credit Card Interest Rate in India: 42% APR, Decoded

A credit card offering rewards, cashback, and flexible payments can seem like a smart financial tool, but not when you’re charged interest on the dues.

The credit card interest rate in India on most cards is 3.5% a month. Multiply by 12 and you get 42% a year, which is the APR (annual percentage rate) banks print.

However, the interest you pay is higher than that. Because banks add each month's unpaid interest to what you owe, and the next 3.5% is charged on the bigger number. Twelve months of it amounts to: (1.035^12 − 1) = 51.1%

So, if you owe your card issuer ₹100 and pay nothing for a year, your due amount in twelve months becomes ₹151.10.

TL;DR

• Pay your full statement amount every month, and the interest rate never touches you. Pay less, and the interest starts from the day you swiped.
• A ₹50,000 balance on the minimum due takes 15 years and 5 months to clear. You'd pay ₹99,099 in interest.
• If you can't clear a bill, move it to a card EMI or a personal loan within the week. Don't leave it on the minimum.

3.5% hurts more than it sounds

One short payment ends your interest-free period

If you pay the full statement amount by the due date, your purchases cost nothing. That free window runs roughly 20 to 50 days, depending on where in the billing cycle you bought. But pay even slightly less, and the interest-free window is gone.

HDFC's terms say the free period applies "only if all previous dues are paid in full." All banks have similar terms that may be stated in slightly different combinations of letters.

After the grace period, every new purchase starts collecting interest the day you make it. The bank also charges interest on your whole outstanding balance, not only on the part you didn't pay.

To get your interest-free period back, you have to clear all the dues.

Interest runs from the day you swipe, not the day the bill arrives

Banks levy the interest rate on a per-day basis. So, dividing an annual rate of 42% by 365 comes to 0.115% a day. That’s about ₹11.50 a day on every ₹10,000.

Say you're already carrying a balance and you buy something for ₹10,000 on day 2 of your cycle. Your clock starts ticking from that day itself. By the time the card statement is generated on day 27, that purchase has collected about ₹290 in interest.

Cash advances never get a free day

ATM withdrawals on a credit card have no interest-free period at all. Interest runs from the day the cash comes out until you repay in full. On top of that, HDFC, SBI Card and Kotak publish a cash advance fee of 2.5%, with a minimum of ₹500.

On ₹10,000, 2.5% is only ₹250, so the ₹500 minimum applies. Even if you repay the cash the next morning, you’ll be paying about ₹512 (₹500 + one-day interest); and that’s before GST.

And if you keep that cash advance fee due for a month, it becomes ₹850 (₹500 fee plus ₹350 interest) + GST.

What happens when you can't clear a ₹50,000 statement?

Say ₹50,000 is sitting on your card after a hospital advance or a semester fee. You can't clear it this month, so you pay the minimum due and plan to sort out the rest later.

Now, if we assume an interest rate of 3.5% a month, the minimum due is set at 5% of the bill, no late fees, and no new purchases, here's what it costs you.

Six months in, you've paid ₹14,890 (excluding GST) and still owe ₹45,181. About two-thirds of everything you paid went to interest.

The balance barely moves because the minimum due is small. In month one you pay ₹2,588. Of that, ₹1,750 is interest and only ₹838 reduces what you owe. Next month you owe slightly less, so the minimum is slightly lower too. The payment never speeds up.

Want to know when you’ll clear the full amount due?

• After 12 months, you've paid ₹28,344 and owe ₹40,826.
• The balance halves, to ₹25,000, in month 42. That's three and a half years.
• It reaches zero in month 185. That's 15 years and 5 months.

In those 15 years and 5 months, the total amount paid will be ₹1,49,099. So, the interest alone is going to be ₹99,099, nearly twice the amount you borrowed.

Banks also add 18% GST on the interest, which on ₹99,099 is roughly ₹17,800 more, at least.

Watch out: paying the minimum due isn't wrong in itself. It keeps you clear of the late fee (Kotak charges ₹1,100 to ₹1,300 on balances above ₹25,000) and of a late-payment mark on your CIBIL score. If cash is tight this month, pay the minimum on time. Treat it as a one-month exit, not a long-term plan.

Where your card sits on the rate

Cards don't all charge the same, though the spread is narrower than most people expect. Most mainstream cards sit between 40% and 45%. The gap between 3.35% and 3.75% is ₹200 a month on ₹50,000.

A handful of premium and small-bank cards have a lower interest rate, in the mid-20s. But banks keep revising these terms.

If you can't pay your balance

If you can't pay the full due amount this month, don't let the balance revolve. Move it to something cheaper within the week. It can be a card EMI (roughly 12% to 24% a year) or a personal loan (roughly 9% to 21%). Our credit card EMI vs personal loan guide runs that comparison in full.

On your ₹50,000, a 24% card EMI over 12 months costs about ₹6,700 in interest, against ₹12,090 at 3.5% a month. But both options only work if the card stays near zero afterwards.

If you spend ₹50,000 on the card again the very next month, you owe both. EMI conversion also carries a processing fee and keeps part of your limit blocked until you repay. A personal loan needs approval and leaves a hard enquiry on your report.

A long-term fix is to start building a buffer once the card is clear, even ₹1,000 a month, until you have a cushion. That money should be for the next unwanted surprise. Our emergency fund guide shows how much to aim for.

If you're juggling more than one debt, paying off debt in the right order covers which to clear first. Late payments and high utilisation also feed straight into your score, which our CIBIL improvement guide explains.

Find your own rate in three steps

1. Open your latest statement and look for "finance charges" or "interest rate." It's shown as a percentage per month, with the yearly figure next to it.
2. Read the Most Important Terms and Conditions (MITC) or Key Fact Statement from your bank. Check the interest-free period, the cash advance fee and the minimum due rule.
3. Multiply your balance by the monthly rate. That's roughly what next month's interest will be.

FAQs about credit card interest in India

What is the credit card interest rate in India?

Most major cards charge 3.5% to 3.6% a month, which is 42% to 43.2% a year. A few premium and small-bank cards go down to about 24% to 30% a year, and some go up to 45%. Each bank sets its own rate.

How is credit card interest calculated in India?

Banks divide the annual rate by 365 and apply it daily to your outstanding balance, starting from the transaction date. At 42% that's about ₹11.50 a day on ₹10,000. However, if you pay the full statement amount on time, purchases carry no interest.

Is there a limit on credit card interest rates in India?

No. RBI doesn't cap credit card interest rates. In December 2024 the Supreme Court set aside the consumer commission's 30% ceiling, ruling that rates are for RBI and the banks to decide. Banks must disclose the rate, though, so check your MITC.

Do I pay interest if I only pay the minimum due?

Yes. Paying the minimum due keeps you out of late fees, but it doesn't clear the bill. The interest-free period ends, and interest runs on your whole balance and on new purchases from the day you make them.

Is there any interest if I pay my full bill on time?

Not on purchases, provided your previous dues were also paid in full. Cash advances are different. They collect a fee and interest from day one, whatever you pay.

Does credit card interest compound?

Yes. Unpaid interest is added to your balance, and the next month's interest is charged on the larger amount. So, 3.5% a month works out to 51.1% over a year if you pay nothing. RBI's rules say unpaid fees and taxes can't be compounded, but interest can.
