If there is an agreement, it depends on the bank contract, which is divided into monthly repayment, quarterly repayment, half-year repayment and one-time repayment of principal and interest, all of which are deducted on the agreed repayment date. Monthly repayment is also divided into daily repayment and fixed repayment. Daily repayment refers to the repayment of principal and interest on the day of the next month corresponding to the lending date, while fixed repayment refers to the repayment of current principal and interest on a fixed day of each month.

When to deduct interest from bank loans depends on the time you agreed with the bank. Generally speaking, debt refers to the behavior that the creditor provides funds to the debtor to obtain interest, and the debtor promises to repay these funds on an agreed date in the future. Personal debt interest refers to the legal act that the creditor provides funds to the debtor, and the debtor promises to repay these funds and their agreed interest on an agreed date in the future. In other words, the deduction time is when you sign a loan contract and have an agreed repayment date with the bank. I hope it helps you.
