To put it simply: if the other company pays you a bank acceptance bill instead of paying you money in the process of selling goods, you can handle the acceptance bill in three ways: first, endorse it and transfer it to others; Second, collect money from your bank when the acceptance bill expires; Third, if you don't return it to others, you will go to the bank for discount before the due date.

Discounting is to use this paper-based bank acceptance bill to exchange money with the bank, and pay certain interest according to the current discount rate of the bank when discounting.

If the face value of your bank acceptance bill is 654.38 million, the bank discount rate is 2.2%, and the maturity date is July 1, then the discount interest you have to pay = current interest rate /30 days * acceptance amount * days = 2.2% * 30 *10000 *10.

In other words, you can withdraw100000-1247 = 98753 yuan from your bank account, which is the paper money value that can be exchanged for this acceptance bill according to the above conditions.
