If you apply for billing installment of CCB, you will apply from the billing date to the final repayment date. You can apply for bill installment between March 26th and April 13th for the bill settled on March 25th. If you successfully apply, the installment amount of the first installment will be settled on the billing date of April 25th.

for example, suppose that the total repayable amount of your 3/25th bill is 5, yuan, and you applied for 4,5 yuan bill installment. If you repay the remaining 5 yuan before 4/14th, your bill will be fully repaid in this period, and consumption will still enjoy the interest-free period. You don't have to continue the repayment before April 14th, but your consumption will not enjoy the interest-free period, and the bank will charge interest in full at five ten thousandths of a day from the date when your consumption is recorded. Then the first installment, the current installment and the handling fee will be settled on the billing date of 4/25, just as 2 days after the billing date is the final repayment date, so you can repay normally. If you repay the loan in full on time, you will also enjoy the interest-free period in installments. If you don't repay the loan in full on time, like consumption, the interest will be charged in full by five ten thousandths of a day from the date of entry. In other words, if you repay in full on time, there will be no interest in installments.

I hope I can help you and hope to adopt it!
