The interest rate of the bank is the annual interest rate, such as 10000 yuan, and the interest rate for three months is 1.0%, so the interest you get at the expiration of three months is (100000.05438+0)/4 = 25 yuan; The interest rate for six months is 1.5%, and the interest rate is (100000.05438+05)/2 = 75 yuan; The annual interest rate is 2.0%, and the interest is 100000.02=200 yuan; The interest rate for two years is 2.5%, and the interest rate is 100000.025=250 yuan. At the end of two years, it is 2502=500 yuan. The so-called interest rate is the abbreviation of "interest rate", which refers to the ratio of interest amount to deposit principal or loan principal in a certain period of time. Usually divided into annual interest rate, monthly interest rate and daily interest rate. Daily interest rate = annual interest rate /360, monthly interest rate = annual interest rate/12.
1. Interest rate refers to the ratio of the interest amount due in each period to the par value of the borrowed, deposited or borrowed amount (called the total principal). The total interest of the lent or borrowed amount depends on the total principal, interest rate, compound interest frequency and the length of time of lending, deposit or borrowing. Interest rate is the price that the borrower needs to pay for the money borrowed, and it is also the return that the lender gets by delaying his own consumption and lending it to the borrower. The interest rate is usually calculated by the percentage of one-year interest to the principal.
2. Calculation formula of interest: principal × annual interest rate (percentage) × deposit period.
If the interest tax is X (1-5%)
Total principal and interest = principal interest
The calculation formula of accrued interest is: accrued interest = principal × interest rate × time.
Accrued interest shall be accurate to two decimal places, and the number of interest-bearing days shall be calculated according to the actual holding days.
3. With regard to the starting point of the interest-bearing formula, the starting point of interest-bearing for savings deposits is RMB yuan, and no interest-bearing for points below RMB yuan; The interest amount is calculated to the decimal point, and the decimal point is rounded off when actually paid; All other savings deposits, regardless of the duration of deposit, are paid off with the principal at the time of withdrawal, excluding compound interest, except that the current savings are settled on an annual basis and the interest can be converted into principal; Compound interest: compound interest means adding interest at a certain interest rate. According to the regulations of the central bank, if the borrower fails to repay the interest at the time agreed in the contract, it will be charged with compound interest. Penalty interest: If the lender fails to repay the bank loan within the specified time limit, the penalty interest paid by the bank to the non-observant according to the contract signed with the parties is called bank penalty interest.
How to calculate the interest on bank loans?
1. simple interest method simple interest method means that during the loan term, on the agreed interest collection date, interest is only calculated according to the loan principal, and the interest not collected in the previous period is not used as the basis for calculating the interest in the current period. Commercial banks in China use simple interest method to collect loan interest. The calculation formula is: interest = loan principal × loan daily interest rate × loan days.
2. Compound interest method The compound interest method means that if the interest of the previous period is not received on the agreed interest collection date within the loan term, the interest of the previous period should be included in the principal as a new interest base, and interest should be calculated and collected on this basis. Compound interest is commonly known as "rolling interest". The calculation formula is: sum of principal and interest = loan principal ×( 1 interest rate) n power interest = principal × [( 1 interest rate) n power 1].
3. Discount method Discount method refers to the method that commercial banks deduct interest from the principal in advance when issuing loans, and borrowers repay the principal and interest at one time when due. Commercial banks usually use this method when discounting commercial bills for customers. The calculation formula is: interest = loan principal (or face value) × loan days × discount date interest rate.
4. The principal and interest installment method refers to a method of repaying principal and interest regularly during the loan period. This law is applicable to housing mortgage loans and other loan projects with large amount and long term. There are two different options for commercial banks to repay principal and interest by installments.
How much is the interest on the bank loan?
The calculation formula of bank loan interest is: interest = principal interest rate, loan term, and the annual interest rate of bank loan is about 4.5%, so the interest of loan for 50,000 years is 50,000 times 4.5% = 2,250 yuan.
So the interest on a bank loan of 50,000 yuan a year is about 2,000 yuan, but the interest on applying for a loan in a bank is often not calculated like this. After the loan, you can apply for installment repayment, so the interest generated in each installment will be much lower.
Interest is the use fee of money in a certain period of time, and it refers to the reward that money holders (creditors) get from borrowers (debtors) for lending money or monetary capital. Including deposit interest, loan interest and interest generated by various bonds.
1. Money other than the principal of deposits and loans (different from "principal").
2. The abstract interest point refers to the value added when monetary funds are injected into the real economy and returned. In a less abstract sense, interest generally refers to the remuneration paid by the borrower (debtor) to the lender (creditor) for using the borrowed currency or capital. Also known as the symmetry of sub-fund and parent fund (principal).
The calculation formula of interest is: interest = principal × interest rate × deposit period (i.e. time).
Interest is the reward that the fund owner gets for lending the fund, which comes from a part of the profits that the producer makes by using the fund to play its operational functions. Refers to the value-added amount brought by monetary funds injected into the real economy and returned.
The calculation formula is: interest = principal × interest rate × deposit period × 100%.
3. Classification of bank interest
According to the different nature of banking business, it can be divided into bank interest receivable and bank interest payable.
Interest receivable refers to the remuneration that the bank obtains from the borrower by lending to the borrower; It is the price that the borrower must pay for using the funds; It is also part of the bank's profits.
Interest payable refers to the remuneration paid to depositors by banks to absorb their deposits; It is the price that banks must pay to absorb deposits, and it is also part of the cost of banks.
How to calculate the loan interest?
The calculation formula of loan interest is loan interest = principal x time x interest rate.
Loan interest refers to the reward that the lender gets from the borrower for issuing monetary funds, and it is also the price that the borrower must pay for using the funds.
Bank loan interest rate refers to the ratio of interest amount to principal amount during the loan period. The interest rate of loan contracts with banks and other financial institutions as lenders can only be determined through consultation within the upper and lower interest rate limits stipulated by the People's Bank of China.
If the loan interest rate is high, the repayment amount of the borrower will increase after the loan term, otherwise it will decrease.
There are three factors that determine loan interest: loan amount, loan term and loan interest rate.
How to calculate the loan interest formula
(1) The interest rate conversion formula for RMB business is as follows
1, daily interest rate (0/000)= annual interest rate (%)÷360= monthly interest rate (%) ÷ 30
2. Monthly interest rate (%) = annual interest rate (%)÷ 12.
(two) banks can use the product interest method and the 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 = cumulative interest-bearing product × daily interest rate, where cumulative interest-bearing product = total daily balance.
2. Transaction-by-transaction interest calculation method calculates interest one by one according to the preset interest calculation formula: interest = principal × interest rate × loan term, with three details:
If the interest-bearing period is a whole year (month), the interest-bearing formula is:
① Interest = principal × year (month )× year (month) interest rate
If the interest-bearing period is a whole year (month) and days, the interest-bearing formula is:
② Interest = principal × year (month) × year (month) interest rate principal × odd days × daily interest rate.
At the same time, banks can choose to convert all interest-bearing periods 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 as follows:
③ Interest = principal × actual days × daily interest rate
These three formulas are essentially the same, but because the interest rate conversion is only 360 days a year. However, when calculating the actual daily interest rate, it will be calculated according to 365 days a year, and the result will be slightly biased.
Extended data
The decisive factors of bank loan interest are:
1, bank cost. Any economic activity needs cost-benefit comparison. There are two types of bank costs: borrowing costs-prepaid interest on borrowed funds; Additional cost-the cost of normal business.
2. Average profit rate. Interest is the subdivision of profit, which must be less than the profit rate, and the average profit rate is the highest limit of interest.
3. Supply and demand of loan funds. If the supply exceeds the demand, the loan interest rate will inevitably fall, and vice versa. In addition, the loan interest rate must also consider price changes, securities returns, political factors and so on.
However, some scholars believe that the upper limit of interest rate should be the marginal rate of return of funds. The factor that restricts the interest rate is regarded as the comparison between the profit growth rate of enterprises after borrowing bank loans and the loan interest rate. As long as the former is not lower than the latter, it is possible for enterprises to borrow money from banks.
1, compound interest: compound interest means adding interest at a certain interest rate. According to the regulations of the central bank, if the borrower fails to repay the interest at the time agreed in the contract, it will be charged with compound interest.
2. Penalty interest: If the lender fails to repay the bank loan within the prescribed time limit, the penalty interest paid by the bank to the non-defaulting party according to the contract signed with the parties is called bank penalty interest.
3. loans overdue liquidated damages: the nature is the same as penalty interest, and it is a punitive measure for the defaulting party.
