The interest free grace period could range from 20 to 50 days, depending upon date of transactions, provided there are no previous outstanding on the card. Example: This means that a customer who has a billing date of 1st of the month can spend on his Card from 1st April to 30th April, his bill will be generated on 1st May and his Payment Due Date will be 20th May. Hence a purchase made on 14th April will have interest free grace period of 37 days, while a purchase made on 20th April will have interest free grace period of 31 days. However, this is not applicable if the Previous month’s balance has not been cleared in full or if the Card member has availed of cash from ATM.
