In fact, demand changes more frequently. In order to facilitate the calculation, the banking system calculates its own products every day. When calculating the interest on the account closing or interest settlement date (current account is generally 265438+ the 0 th day of each month), you can directly use the daily interest rate, so you don't have to worry about the previous changes. Interest bearing on deposits and loans is a way for banks to bear interest. It is the basis for calculating interest on demand deposits and loans. The so-called product is the final balance occupied by the deposit and loan account every day, that is, the actual deposit amount or the actual loan amount occupied by the deposit and loan unit in the bank every day. Banks add up the book balances of deposits and loans every day, which is accumulated over time. For example, a deposit company deposits 1 00 yuan on February/day, and withdraws it on the 5th, which accumulates in 400 yuan.

There are two ways for domestic banks to calculate products: one is to copy the daily balance of each sub-account according to the account, and the other is to record the products in the "products" column of the account according to the end-of-day balance of the sub-account (that is, to calculate the products on the account page, the former should be checked with the balance of the same account in the general ledger after adding the accounts, and the latter should be checked with the "accumulated products of this month" in the general ledger at the end of the month. Because the accumulated products calculated by the above method are daily products, and the bank interest rate adopts monthly interest rate or annual interest rate, it is necessary to convert the accumulated products into monthly products or annual products or the interest rate into daily interest rate when calculating interest.

Interest-bearing product is the daily cumulative sum of the customer's deposit or loan balance during the interest-bearing period (if the balance has not changed for several days, it is multiplied by the number of days that have not changed), which is the interest-bearing product. According to the stipulated annual interest rate or monthly interest rate, the daily interest rate multiplied by the interest-bearing product is the interest receivable or payable by the household in the current period. There are two ways to calculate products: using balance tables and using ledgers. Use balance table to calculate products, which is suitable for accounts with frequent balance changes; Use subsidiary ledger to calculate products, which is suitable for accounts with irregular balance changes. The product calculated by the above two methods. Add by account, and check with the interest-bearing product in the general ledger of this account to verify whether the calculated product is wrong.
