According to relevant regulations, the difference between credit card bill installment and cash installment mainly lies in the following aspects: 1. In meaning, bill installment means that after the credit card issues the bill of the current month, if the cardholder is under the pressure of full repayment, he can choose to repay the total bill by installment. Cash installment refers to a method of installment in which the cardholder applies, the issuing bank converts the cardholder's credit card amount into cash, transfers it to the debit card account designated by the cardholder, and the cardholder repays according to the specified number of installments. 2. The object of installment is different: the object of bill installment is "credit card bill" and the object of cash installment is "cash". 3. Different installment numbers and handling fees: In practice, different banks have different handling fees due to different installment numbers. 4. Different limits: All consumption parts in bill installment can apply for bill installment, up to 95% of the current bill amount. The amount of cash installment is specifically related to the cardholder's credit card amount and his own qualifications, and also related to the relevant bank policies.
