If you don’t want to incur interest, you can just pay off the “entire repayment amount of the current period” each time.

The detailed explanation is as follows:

Last period's bill balance: It means that you have only paid part of the full amount of the last period's debt. As shown in the picture, you still have 952.31 yuan to pay.

New accounts in this period: refers to your new consumption in this period.

As shown in your picture, that is, the consumption occurred between the last bill date and August 26.

Amount repaid in this period: It is the amount you have paid in this period. That is 1210 yuan as shown in the picture.

The interest this time is due to the fact that you did not repay the "full repayment amount of the previous period", which is the remaining 952.31 yuan.

Hope this helps.
