Key takeaways
- Pay the total amount due by the due date and you pay zero interest on purchases.
- Leave any balance unpaid and interest is charged from each transaction date, not the due date.
- You also lose the interest-free period on new purchases until the balance is cleared.
- Rates are about 3–3.75% a month (roughly 36–45% a year), plus 18% GST on the interest.
Credit card interest in India works differently from most loans, and that's why it gets so expensive so quickly. Here's exactly how it's calculated, with examples.
The interest-free period
Purchases don't attract interest if you pay the total amount due by the due date. That gives you up to about 45–50 days of free credit, depending on when in the cycle you buy. The day after your statement date is best. See the interest-free period calculator.
What happens if you don't pay in full
- Interest is charged from each transaction date, not from the due date, on the purchases in that statement.
- It's calculated daily on your outstanding balance at the monthly rate (for example 3.75% a month ≈ 0.123% a day).
- New purchases lose their interest-free period and attract interest from the day you make them, until the balance is fully cleared.
- 18% GST is added to the interest.
Rates vary by card, from about 3% to 3.75% a month on most cards (Axis Bank raised its finance charge to 3.75% a month in December 2025), with lower rates on some premium or lifetime free cards. Check your card's MITC.
Example 1: paying most of the bill
Your statement (date: 5 June) shows ₹30,000, made up of purchases on 10 May (₹20,000) and 25 May (₹10,000). The due date is 25 June. You pay ₹25,000 on the due date, leaving ₹5,000. At 3.75% a month (about 0.123% a day):
- Interest on ₹20,000 from 10 May to 25 June (46 days): about ₹1,130
- Interest on ₹10,000 from 25 May to 25 June (31 days): about ₹380
- Interest on the remaining ₹5,000 from 25 June to your next statement date (5 July, 10 days): about ₹60
- GST at 18% on all of this: about ₹285
Total: roughly ₹1,860 in interest and GST, even though you paid 83% of the bill. Many banks calculate interest on the whole statement balance from the transaction dates once you don't pay in full, which is why a small shortfall can be so expensive. Methods vary slightly by bank, so check your MITC for the exact method.
Example 2: paying only the minimum
On a ₹50,000 balance at 3.75% a month, paying only the minimum (about 5%) with no new spending can take years to clear, and the total interest plus GST can exceed the original amount. See the exact timeline in our interest calculator and our guide to the minimum amount due.
Example 3: a cash withdrawal
Cash advances have no interest-free period: interest starts on the day you withdraw, plus a fee of about 2.5% (minimum ₹300–₹500) and GST. A ₹20,000 withdrawal repaid after 30 days costs about ₹1,400. See our cash withdrawal guide.
Annual rate vs monthly rate
| Monthly rate | Annual rate (simple) | With 18% GST |
|---|---|---|
| 2.5% | 30% | 35.4% |
| 3% | 36% | 42.5% |
| 3.5% | 42% | 49.6% |
| 3.75% | 45% | 53.1% |
How to stop paying interest
- Pay the total amount due every month, ideally with auto-debit.
- If you can't, convert the balance to EMI at a lower rate, or use a personal loan. Compare them in our EMI vs personal loan guide.
- Stop new spending on the card until the balance is cleared, since new purchases attract interest immediately.
- Consider a balance transfer to a lower-rate card. See the balance transfer calculator.
Your rights
Interest rates and the calculation method must be disclosed in your card's MITC, with illustrations. Banks must give advance notice of rate changes. From 1 April 2027, under RBI's April 2026 amendment, late payment charges apply only to the amount outstanding after the due date. That's a separate rule from interest.
FAQs
Is credit card interest charged from the transaction date?
Yes. If you don't pay the total amount due, interest is usually charged from each transaction date, not the due date.
What is the interest rate on credit cards in India?
Typically about 3–3.75% a month (roughly 36–45% a year), plus 18% GST on the interest. Some cards charge less.
If I pay the full bill, do I pay any interest?
No. Paying the total amount due by the due date means no interest on purchases. Cash withdrawals still attract interest from day one.
Why was I charged interest when I paid most of my bill?
Once you don't pay in full, banks usually charge interest from the transaction dates on the statement's purchases, and new purchases lose their interest-free period.
Is the interest rate the same on every credit card?
No. Rates vary by bank and card, typically about 3–3.75% a month, with some premium or lifetime free cards offering lower rates. Check your MITC.
Does paying before the statement date reduce interest?
If you already carry a balance, paying earlier reduces the daily balance and so the interest. If you pay in full every month, there's no interest anyway.
