The time for overdue credit card interest installments depends on the following factors:

1. Number of overdue days: Usually, the longer the overdue time, the more difficult it is to obtain the opportunity to apply for interest suspension installments. Banks will evaluate the borrower's repayment ability and credit risk based on the number of overdue days.

2. Credit record: The bank will comprehensively consider the borrower's credit record, such as past repayment records, the borrower's overdue status in other financial institutions, etc. If the borrower has a good credit record, the bank may be more willing to provide an interest-free installment.

3. Bank policies: Different banks have different policies and regulations. Some banks may have specific requirements on overdue time. For example, interest suspension installments can only be processed if the overdue period is more than 90 days; while other banks may consider it based on the specific circumstances of each case.

According to comprehensive analysis, under normal circumstances, if a credit card is overdue for more than 60 days, the bank may consider requiring the borrower to apply for an interest suspension installment. However, the specific time depends on bank policies, overdue days, credit history and other factors.

In short, the specific time for overdue credit card interest suspension installments depends on the bank's policy and the borrower's personal credit situation. It is recommended to contact the bank in time to understand the specific requirements and possible solutions.

Additional information: Late payments will have a negative impact on an individual's credit record and may have an impact on future borrowing or credit facilities. Therefore, it is recommended to pay off overdue amounts in a timely manner to maintain a good credit record and better protect your own credit status. To avoid late repayments, you can ensure on-time repayments through proper planning and management of personal finances.
