Debt interest calculation formula: Principal X annual interest rate (percentage) X total time of deposit.

Interest refers to the interest earned regularly by fund assets from investing in different types of bonds (treasury bonds, local government bonds, corporate bonds, financial bonds, etc.).

my country's "Interim Measures for the Management of Securities Investment Funds" stipulates that the proportion of a fund investing in government bonds shall not be less than 20% of the fund's net asset value.

Bonds are securities issued by debtors such as governments, enterprises, and banks to raise funds in accordance with legal procedures and promise to repay principal and interest on a specified date.

Bonds are a kind of financial contract. When governments, financial institutions, industrial and commercial enterprises, etc. directly borrow funds from society, they issue them to investors and promise to pay interest at a certain interest rate and repay the principal according to agreed conditions.

The essence of a bond is a certificate of debt, which is legally binding.

The relationship between bond buyers or investors and issuers is a creditor-debt relationship. The bond issuer is the debtor, and the investor (bond buyer) is the creditor.

A bond is a marketable security.

Because the interest on a bond is usually determined in advance, a bond is a type of fixed-interest security (fixed-rate security).

In countries and regions with developed financial markets, bonds can be listed and circulated.

The face value of a bond refers to the face value of the bond. It is the amount of principal that the issuer should repay to the bond holder after the bond matures. It is also the basis for calculating the periodic interest payments by the company to the bond holder.

The face value of the bond is not necessarily consistent with the actual issuance price of the bond. An issuance price greater than the face value is called a premium issue, a price less than the face value is called a discount issue, and an equal price issue is called a par issue.

The bond repayment period refers to the period for repaying the bond principal specified on the corporate bond, that is, the time interval between the bond issuance date and the maturity date.

The company must determine the repayment period of corporate bonds based on its own capital turnover status and various influencing factors in the external capital market.

The interest payment period of a bond refers to the time for interest payments after the company issues the bond.

It can be paid once upon maturity, or once every year, half a year or three months.

Taking into account the time value of money and inflation, the interest payment period has a great impact on the actual return of bond investors.

The interest on a bond that pays interest once upon maturity is usually calculated as simple interest; while the interest on a bond that pays interest in installments during the year is calculated as compound interest.
