the longest interest-free period of 5 to 56 days will be placed in the most conspicuous position in most credit card related publicity materials, and the interest-free period is also one of the biggest temptations for cardholders in today's increasingly advanced consumption consciousness. But don't take it for granted that as long as you have a credit card, all your overdraft expenses will have an interest-free period of 5 to 56 days. If you study your card instructions and bill details carefully, you will find that in fact, only a few expenses or even none can really enjoy such a long interest-free treatment.

so, how is the interest-free period calculated? Credit cards of different banks have different calculation methods, but there are generally two types: first, it is clearly stipulated that one day of each month is the interest-free deadline, and the interest-free period is the date from the consumption date to the deadline; Second, the cardholder sets a billing date, and then sets the latest repayment date according to the billing date. The interest-free period is the date from the consumption date to the latest repayment date.

the first method is ICBC peony credit card. Among them, ICBC stipulates that this month's consumption will be interest-free until the 25th of next month. Assuming that the cardholder spent on the 3th of last month, the interest-free period will be 25 days as of the 25th of this month. This billing method is relatively easy to understand, and it is easy for cardholders to use the longest interest-free period for smart consumption. For example, your large overdraft occurred on the 1 ST of last month, and your interest-free period may become the longest 56 days, which can save a lot of interest.

the second method allows cardholders to choose more billing days according to their personal situation.
