Credit card installments will occupy a fixed amount. According to relevant public information, installment refers to repaying the credit card consumption amount according to the installment plan to reduce the repayment pressure of consumers. The consumption amount of the credit card installment will be immediately frozen and occupy the fixed limit of the credit card. This part of the limit will be used in the installment plan. It cannot be used before the repayment is completed. Therefore, when consumers make installment purchases with credit cards, they need to pay attention to the occupied limit to avoid exceeding the credit card limit.
