How Credit Card Interest Is Calculated in India

Credit card interest in India is calculated using the daily balance method and applied monthly.

  • Most banks charge 3%–3.6% per month (36%–42% annually).
  • GST of 18% is charged on the interest amount, not on the principal.

Credit card interest in India is not simple interest. It is calculated on a daily basis using the APR (Annual Percentage Rate) divided by 365.

If you have an outstanding balance, the Interest-Free Period is immediately revoked. This means every new purchase you make attracts interest from the very first day, in addition to the interest compounding on your previous balance.

Indicative Monthly Interest Rates (May Vary)

  • ICICI / HDFC / Axis~3.5% p.m.
  • SBI Cards~3.0%–3.35% p.m.
  • Premium / Super PremiumMay be lower

* Rates are indicative and subject to change by banks.

Why Your Bill Is Not Reducing

  1. Monthly interest (3%–3.6%) is added to your outstanding balance.
  2. 18% GST is charged on the interest amount (extra cost).
  3. Minimum amount due payments mostly cover just the interest, reducing very little principal.
  4. New purchases lose the interest-free period and attract interest instantly.

The Math

If you pay ₹5,000 (Minimum Due) on a ₹1 Lakh balance, almost ₹3,500 goes towards Interest + GST. Only ₹1,500 is reduced from your principal. EMI interest calculation works differently.

The Result

You will take years to clear the debt, paying 3x to 4x the original amount in pure interest. Compare EMI vs minimum due to save.
