The Interest-free credit period for using your credit limit is up to 62 days. To qualify for this, you must fully repay all outstanding debt as per your Bill Statement by the last day of the month in which the bill is generated. Let’s say you haven’t used your card before, and you make a purchase of ₹1,00,000 on August 1st and another ₹50,000 on August 30th. If you pay off the entire amount before September 30th, you will remain within the Interest-free credit period and pay 0% interest on your credit.
