"Discount interest" is the abbreviation of "discount interest", which refers to the discount interest paid to the bank by the holder of the bill of exchange for the discount face amount applied to the bank.

Calculation method of discount interest:

Discount interest = discount amount × number of discount days × daily discount rate

Daily discount rate = monthly discount rate ÷ 30

Actual payment amount = face amount - discount interest

Interest discounts are divided into three types: housing discounts, loan discounts, and deposit discounts.

Housing subsidy: The full name is "Policy Interest Subsidy Business for Personal Housing Loans". Commercial banks issue loans. The amount of the discount is based on the loan amount that can enjoy the discount, using the provident fund loan interest rate and the commercial bank loan interest rate. The calculated interest difference is paid to the individual by the Housing Provident Fund Management Center;

Loan discount: Subsidy loan is a commercial individual housing loan issued by the Provident Fund Management Center in cooperation with the relevant commercial bank. For loans, for borrowers who meet the interest discount conditions of the Management Center, the Management Center will provide interest discounts based on the interest discount amount that the borrower can apply for and the interest rate difference between commercial personal housing loans and housing provident fund loans;

Deposit interest discounts: It is the negative deposit interest deducted based on the discount rate. For example, if you have an acceptance bill or time deposit certificate due in three months, and you need to use cash now, if you exchange it for cash, the person who accepts it will lose three dollars. If you pay monthly interest, the interest loss needs to be deducted from the cash given to you. The interest deducted is the deposit discount.
