Cash installment, sometimes called cash withdrawal installment, is generally a installment method in which the cardholder applies or the issuing bank invites the cardholder to apply, converts the credit limit in the cardholder's credit card into cash, transfers it to the designated debit card (the Bank or other banks), and returns it in specified monthly installments.

Cardholders can use cash in advance only by returning the fixed principal and handling fee every month. Generally, the handling fee rate of cash installment will be higher than that of the issuing bank that consumes installment products and lower than the circulation interest rate of 0.5‰.
