Hello, after the overdue of Guangfa Credit Card, all consumer transactions will receive interest at the overdraft daily interest rate from the transaction date, and compound interest on a monthly basis until the bill amount is paid off. If the installment payment in the bill is not paid off in full, the installment principal/installment fee will be charged with interest, and the overdue repayment penalty, annual fee and cash withdrawal fee will not be charged with interest.

for example, the billing date is 5th, the repayment due date is 25th, and if the circulating daily interest rate is .5%, the annualized interest rate will be 18.25%. Spend RMB 1, on January 1st, settle the bill on January 5th, repay RMB 1 on January 25th, and repay RMB 9 on January 3th. Consumer interest =1 yuan *.5%*24 days (1-24th) +9 yuan *.5%*5 days (25th-29th) =14.25 yuan.
