The amount payable in this period refers to the sum of your credit card consumption records last month.
The reasons for the difference between the remaining repayment amount and the current repayment amount are as follows:
1. Did you pay more in the last period?
2. There was one or several refunds in your credit card record last month (for example, Taobao bought something, but it didn't look good, so it was refunded).
You bought something at the beginning of this month and got a refund, just before the due date.
4. Did you return a part in advance? I forgot myself.
Just read the statement carefully.
