1. interest calculation method for periodic interest settlement
Regular interest settlement refers to the bank's calculation of accumulated loan products according to the loan account balance table (the calculation method of loan products is the same as that of deposit products), registration of loan interest-bearing account product table, and calculation of interest at the prescribed interest rate at the end of business on the 20th of each month or quarter.
The interest-bearing days for regular interest settlement are calculated by calendar days, one day is counted as one day, and the whole year is counted as 365 days or 366 days. Counting from the beginning to the end, that is, from the date of lending to the date of repayment. The interest settlement date should be included in the calculation of the interest settlement date.
Its formula is
Loan interest = accumulated loan interest product × daily interest rate
For example, a bank issued a short-term loan of 200,000 yuan on May 2, assuming that the monthly interest rate is 4‰ and the term is 4 months, then:
① When the bank settles interest on June 20th every quarter, the accrued interest of the loan is:
200,000 yuan ×50 days ×4‰÷30= 1333.33 (yuan)
② When the loan is repaid from June to September 2 in 21year, the accrued interest of the loan is:
200,000× 73× 4 ‰-30 =1946.67 (yuan)
③ If the bank fails to receive the interest of 1333.33 yuan on June 20th, the accrued interest of the loan is:
1333.33+(200000+1333.33) × 73× 4 ‰ ÷ 30 = 3292.97 (yuan)
2. Debt service method.
It means that when the borrower repays the loan, the bank should calculate the loan interest according to the loan days from the loan date to the day before the repayment date.
When the loan is full, it will be calculated on an annual basis, and when it is full, it will be calculated on a monthly basis, and the fraction of the whole year (month) can be calculated on a daily basis. 360 days a year, 30 days a month, a fraction of a day.
Its calculation formula is:
Loan interest = loan amount × loan days × daily interest rate.

Influencing factors of interest rate:
1, central bank policy
Generally speaking, when the central bank expands the money supply, the total supply in loanable funds will increase, the supply exceeds demand, and the natural interest rate will decrease accordingly; On the contrary, the central bank implements a tight monetary policy, reducing the money supply, so that loanable funds's demand exceeds supply, and interest rates will rise accordingly.
2. Price level
Market interest rate is the sum of real interest rate and inflation rate. When the price level rises, the market interest rate also rises accordingly, otherwise the real interest rate may be negative. At the same time, due to rising prices, the public's willingness to deposit will decrease, while the loan demand of industrial and commercial enterprises will increase. The imbalance between deposit and loan caused by loan demand exceeding loan supply will inevitably lead to an increase in interest rates.
3. Stock and bond markets
If the securities market is on the rise, the market interest rate will rise; On the contrary, interest rates are relatively low.
4. International economic situation
Changes in a country's economic parameters, especially the exchange rate and interest rate, will also affect the fluctuation of interest rates in other countries. Naturally, the rise and fall of the international securities market will also bring risks to the interest rates faced by international banking business.
