The calculation of bank loan interest, except for 360 days, is not 365 days: for the convenience of calculation;
There are 12 months every year, and there are only 30 days in a month according to 360 days.
The calculation of bank loan interest, except for 360 days, is not 365 days: for the convenience of calculation; There are 12 months every year, and there are only 30 days in a month according to 360 days.
：
There are two algorithms for bank loan interest: 360 days and 365 days;
The annual interest rate of general loans is converted into daily interest rate according to 360 days; The daily loan interest rate is converted into the annual loan interest rate by 365 days.
Article 3 of the Notice of the People's Bank of China on the Calculation and Settlement of RMB Deposit and Loan Interest stipulates that the daily interest rate shall be calculated at the annual interest rate of /360.
The Notice of the People's Bank of China on Adjusting the Conversion Standard of Daily Interest Rate of Bond Repurchase stipulates: "The daily interest rate shall be uniformly converted by dividing the annual interest rate by 365 days. If it is not divisible, four digits shall be reserved after the decimal point, and the fifth digit shall be rounded off. "
The Standard for People's Handling of Enforcement Cases promulgated by the Supreme People's Executive Board on 20 17 stipulates in Item (3) of Article 161 of the book: "If the non-performance period exceeds 1 year, the interest shall be calculated at the annual rate of the benchmark interest rate for the same period every full year, and the interest shall be calculated at the daily rate of the benchmark interest rate for the remaining period.
The daily interest rate is calculated by dividing the annual interest rate of the benchmark loan interest rate by 365 days. "The two notices of the People's Bank of China have two ways to calculate daily interest, which lies in the way of interest settlement.
In the Notice of the People's Bank of China on the Calculation and Settlement of Interest on RMB Deposits and Loans, the businesses specified in the notice are settled quarterly. In the Notice of the People's Bank of China on Adjusting the Conversion Standard of Interest Rate on Bond Repurchase Day, for the inter-bank bond market, the interest period is calculated according to the actual days of bond repurchase.
What is the difference? According to the quarterly interest settlement method, there are four quarters every year. The quarterly interest rate is calculated by multiplying the monthly interest rate by 3, and the monthly interest rate is calculated by the annual interest rate/12. The interest rate is the same every month and quarter, but we know that the number of days in each quarter is different.
If the daily interest rate is calculated according to the annual interest rate /365, then the monthly interest rates of 28, 29, 30, 3 1 are different, and the interest rates of each quarter are different, which will lead to confusion in interest rate calculation.
After calculating the daily interest rate with an annual interest rate of /360 and the monthly interest rate with an annual interest rate of/12, the interest rate can be guaranteed to be the same every quarter and every month, thus avoiding the confusion visible to the naked eye. However, the method of calculating interest according to the actual number of days does not have the above problems. In order to ensure that the annual interest rate is the same as the daily interest rate, the interest rate is calculated at the annual interest rate of /365.
After comparison, we found it difficult to say whether to divide by 365 or 360. Whether it is correct or not depends on the interest settlement method, and the calculation method that matches the real transaction can be said to be correct. In business execution, interest is calculated on a daily basis, so the daily interest rate is calculated by dividing the annual interest rate by 365.
How to calculate the interest on bank loans?
Interest = principal × interest rate× loan term
As you said, the loan is 200,000 yuan, with the monthly interest rate of 0.7 1% and the monthly interest payable of 2,000,000.71%1=1420 yuan.
The annual interest rate is 0.71%12 = 8.521%.
The loan is 200,000 yuan, the term is 1 year, the annual interest rate is 8.52 1%, and the annual interest is 200,000 yuan 8.52 1% 1 year = 17042 yuan.
The interest rate of savings deposits shall be stipulated by the state and promulgated by the People's Bank of China. Interest rate, also known as interest rate, is the ratio of interest to principal in a certain date, which is generally divided into annual interest rate, monthly interest rate and daily interest rate. The annual interest rate is expressed as a percentage, the monthly interest rate is expressed as one thousandth and the daily interest rate is expressed as one thousandth. If the annual interest rate of 9% is written as 0.9%, that is to say, every thousand yuan deposit will get a regular annual interest rate of 9 yuan, and the monthly interest rate of 6% is written as 6‰, that is, the monthly interest rate of every thousand yuan deposit is written as 6 yuan, and the daily interest rate is written as 1.5‰, that is, the daily interest rate of every thousand yuan deposit is 65438+50 0 yuan. At present, savings deposits in China are listed at the monthly interest rate. In order to facilitate interest calculation, three kinds of interest rates can be converted, and the conversion formula is: annual interest rate ÷ 12= monthly interest rate; Monthly interest rate ÷30= daily interest rate; Annual interest rate ÷360= daily interest rate.
The interest calculation formula is mainly divided into the following four situations. First, the basic formula for calculating interest. The basic formula for calculating the interest of savings deposits is: interest = principal × deposit period × interest rate;
The second is the conversion of interest rate, in which the conversion relationship among annual interest rate, monthly interest rate and daily interest rate is: annual interest rate = monthly interest rate × 12 (month) = daily interest rate ×360 (day); Monthly interest rate = annual interest rate ÷ 12 (month) = daily interest rate ×30 (days); Daily interest rate = annual interest rate ÷360 (days) = monthly interest rate ÷30 (days). In addition, the use of interest rates should be consistent with the deposit term;
III. Starting point of interest calculation formula, 1, starting point of interest of savings deposit is RMB, and no interest is paid for points below RMB; 2. The interest amount shall be calculated to one decimal place and rounded to one decimal place when actually paid; 3. All savings deposits, regardless of the deposit period, are paid with the principal at the time of withdrawal, excluding compound interest, except that the current savings are settled annually and the interest can be converted into the principal;
Fourth, the calculation of the deposit period is in the interest calculation formula, 1, and the calculation of the deposit period adopts the method of not counting the first number and the last number; 2. Every month is counted as 30 days, regardless of big month, small month, flat month and leap month, and every year is counted as 360 days. 3. The maturity date of all kinds of deposits shall be calculated annually and monthly. If the account opening date is the missing date of the due month, the last day of the due month is the due date.
1. When calculating interest, the number of days of deposit is calculated at the beginning, not at the end, that is, from the date of deposit to the day before withdrawal;
2, regardless of leap year, average year, regardless of the size of the month, 360 days a year, 30 days a month;
3. Calculated by year, month and day, the maturity date of various time deposits shall be subject to year, month and day. That is, from the deposit date to the same day of the following year is a pair of years, and the deposit date to the same day of next month is a pair of months;
4. Maturity date of time deposit. For example, if you don't work on legal holidays, you can withdraw one day in advance and calculate interest at maturity. The procedure is the same as that of early withdrawal.
The 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.
PS: The deposit period should correspond to the interest rate, not necessarily the annual interest rate, but also the daily interest rate and the monthly interest rate.
I. Basic formula for calculating interest The basic formula for calculating interest on savings deposits is: interest = principal × deposit period × interest rate.
II. Conversion of Interest Rate The conversion relationship among annual interest rate, monthly interest rate and daily interest rate is: annual interest rate = monthly interest rate × 12 (month) = daily interest rate ×360 (days); Monthly interest rate = annual interest rate ÷ 12 (month) = daily interest rate ×30 (days); Daily interest rate = annual interest rate ÷360 (days) = monthly interest rate ÷30 (days). Pay attention to the consistency with the deposit period when using interest rates.
Third, the starting point of interest calculation
1. The value point of the savings deposit is RMB yuan, and no interest is paid for the points below RMB yuan.
2. The interest amount shall be calculated to one decimal place and rounded to one decimal place when actually paid.
3. Except that the current savings are settled on an annual basis and the interest can be converted into principal, regardless of the deposit period, the interest of other savings deposits will be paid off with the principal at the time of withdrawal, excluding compound interest.
IV. Calculation of Deposit Term
1, the term of deposit should be calculated at the beginning rather than at the end.
2, regardless of the big month, small month, flat month, leap month, every month is calculated as 30 days, and the whole year is calculated as 360 days.
3. The maturity date of all kinds of deposits shall be calculated on an annual and monthly basis. If the account opening date is the missing date of the expiration month, the expiration date should be the last day of the expiration month.
Five, the calculation of interest on savings deposits, savings deposit interest rate according to the interest rate announced by the People's Bank of China, the implementation of the original currency savings, the original currency interest (secondary currency can be converted into RMB payment according to the foreign exchange rate of the day). Its interest-bearing provisions and calculation methods are compared with RMB deposit methods.
