Calculation of annualized interest rate of bank loans

1. monthly interest rate: that is, the interest calculated on a monthly basis. The calculation method is: monthly interest rate = annual interest rate ÷ 12 (month).

2. Daily interest rate: The daily interest rate is called the daily interest rate, which is calculated on a daily basis. Its calculation method is: daily interest rate = annual interest rate ÷360 (days) = monthly interest rate ÷30 (days).

3. Annual interest rate: usually expressed as a percentage of the principal, and the interest is calculated in years. The calculation method is: annual interest rate = interest ÷ principal ÷ time × 100%.

4. Annualized interest rate: refers to the interest rate at which the inherent rate of return of products is discounted to the whole year, which is quite different from the calculation method of annual interest rate. Assuming that the yield of a wealth management product is a year and the yield is b, the annualized interest rate R is calculated as R =( 1b)A- 1.

5. Calculation formula of equal principal and interest: [loan principal× monthly interest rate× (1 interest rate )× repayment months] ((1interest rate )× repayment months]

6. Average fund calculation formula: monthly repayment amount = (loan principal ÷ repayment months) (principal-accumulated amount of repaid principal) × monthly interest rate.

How to calculate the annual loan interest rate?

1. Calculation formula of annual loan interest rate: daily interest rate 360 or monthly interest rate 12.

1) If the interest-bearing period is a whole year (month), the interest-bearing formula is: interest = principal × year (month )× year (month) interest rate.

2) If the interest period is a whole year (month) and odd days, the interest formula is: interest = principal× year (month )× year (month) interest rate principal× odd days× daily interest rate.

3) At the same time, banks can choose to convert the interest period into actual days to calculate interest, that is, 365 days per year (366 days in leap years), and each month is the actual number of days in the Gregorian calendar of the current month. The interest-bearing formula is: interest = principal × actual days × daily interest rate.

2. Banks can use product interest method and transaction interest method to calculate interest.

1) Accumulate the account balance daily according to the actual number of days, and multiply the accumulated product by the daily interest rate to calculate the interest. The interest-bearing formula is: interest = accumulated interest-bearing products × daily interest rate, where accumulated interest-bearing products = total daily balance.

2) Transaction-by-transaction interest calculation method calculates interest one by one according to the predetermined interest calculation formula: interest = principal × interest rate × loan term. However, because the interest rate conversion is only 360 days a year, when calculating the actual daily interest rate, it will be 365 days a year, and the result will be slightly biased. The central bank gives financial institutions the right to choose which formula to use. Therefore, the parties and financial institutions can agree on this in the contract.

3. The loan interest rates of different institutions will vary greatly. Comparatively speaking, the annual interest rate of banks will be much lower than that of private enterprises. If you borrow money from a bank, the annual interest rate 10% is relatively high. Ordinary banks don't have such a high annual interest rate, even if the loan term is as long as 5 to 10 years, they won't have such a high loan interest rate. Therefore, if you choose to borrow from a bank, and the annual interest rate of the loan reaches 10%, the customer needs to consider it carefully.

1. Customers will only choose loans when the existing funds are insufficient. Therefore, when choosing loans, it is necessary to have a more detailed understanding of the annual interest rates of loans between different institutions and enterprises.

How to calculate the interest formula of loan annual interest rate

The calculation formula of the loan annual interest rate is: interest = the annual interest rate of the loan amount. If the loan is 654.38 million yuan, the term is 1 year and the annual interest rate is 4.35%, then the interest to be repaid is: 10000 14.35 = 4350 yuan. I suggest you calculate the interest yourself before taking out the loan.

Loan means that banks, credit cooperatives and other institutions lend funds to units or individuals who use money, and generally agree on interest and repayment date.

Loans in a broad sense refer to loans, discounts, overdrafts and other borrowing funds. Banks put concentrated money and monetary funds out through loans, which can meet the needs of expanding social reproduction and promoting economic development. At the same time, banks can also obtain loan interest income and increase their own accumulation.

Interest refers to the remuneration paid by the borrower to the lender in order to obtain the right to use funds, which is the use price of funds in a certain period (that is, the loan principal). The loan interest can be calculated in detail by the loan interest calculator.

In civil law, interest is the legal fruit of principal.

Repayment method

(1) Matching principal and interest repayment method: that is, the sum of loan principal and interest is repaid by monthly matching repayment. Most banks have adopted this method for housing provident fund loans and commercial personal housing loans. In this way, the monthly repayment amount is the same;

(2) Equal principal repayment: a repayment method in which the borrower distributes the loan amount to each installment (month) evenly throughout the repayment period and pays off the loan interest from the previous trading day to the repayment date. In this way, the monthly repayment amount decreases month by month;

(3) Paying interest and principal on a monthly basis: that is, the borrower repays the loan principal in one lump sum on the loan maturity date (applicable to loans with a term of less than one year (including one year)), and the loan bears interest on a daily basis and the interest is repaid on a monthly basis;

(4) Repaying part of the loan in advance: that is, the borrower can repay part of the loan amount in advance when applying to the bank, which is generally an integer multiple of 65,438+0,000 or 65,438+0,000. After repayment, the lending bank will issue a new repayment plan, in which the repayment amount and repayment period change, but the repayment method remains unchanged, and the new repayment period shall not exceed the original loan period.

(5) Repayment of all loans in advance: that is, the borrower can repay all the loan amount in advance when applying to the bank, and the loan bank will terminate the borrower's loan at this time after repayment and handle the corresponding cancellation procedures.

(6) Pay back as you borrow: the interest after borrowing is calculated on a daily basis, and the interest is calculated on a daily basis. You can pay the money in one lump sum at any time without paying a fine.
