When an enterprise receives a notice of interest payment from a bank, it shall examine the amount of interest receivable and payable according to the term, amount, interest rate of the deposit or loan and the bank's method of calculating interest. At present, the calculation rules and methods of bank deposit and loan interest are as follows: the deposit account of an enterprise unit and the loan account in the form of regular adjustment and lending calculate interest quarterly, and the interest-bearing date is the 20th of each quarter; For the loan accounts of industrial and commercial enterprises that carry out one-by-one nuclear loan, interest shall be calculated quarterly or on the loan recovery date, and the interest-bearing date of quarterly interest shall be the 20th day at the end of each quarter; When the company cancels the account or transfers money, it shall calculate the interest at the time of cancellation.

The calculation formula of deposit and loan interest of the Bank is as follows:

Principal × Term × Interest Rate = Interest

Cumulative interest-bearing products × daily interest rate = interest

Interest principal × term = interest product

Daily interest rate = monthly interest rate ÷30 (days)

Or daily interest rate = annual interest rate ÷360 (days)

Monthly interest rate = annual interest rate12 (month)

The interest period is "beginning but not ending", that is, the deposit is calculated from the date of deposit to the day before payment; From the date of loan to the day before loan repayment, interest shall be calculated according to the actual deposit or loan days.

For deposits and loans with interest on a case-by-case basis, the full moon interest period shall be calculated on a monthly basis. If there are whole months and odd days, they can be converted into whole days; Regardless of the size of the full moon, it is calculated as 30 days; Insufficient days calculated by actual days.

For demand deposits and loans, interest is calculated according to the actual number of days of deposits or loans. If the bank's interest rate is adjusted, the deposit and loan interest will be calculated in sections. The bank calculates separately according to each time period and interest rate, and then accumulates.

When reviewing the deposit and loan interest, an enterprise shall calculate and review the amount of interest receivable and payable according to the bank's interest calculation method. After it is correct, fill in the voucher according to the interest payment notice and register the relevant account books.
