Calculation method of bank loan interest: Generally, compound interest is calculated on a monthly basis. There are two ways to repay by installments: one is equal principal and interest, and the other is average capital.
The specific formula is as follows:
Matching principal and interest: monthly repayment amount = [loan principal × monthly interest rate× (1interest rate) repayment months ]≤[( 1 interest rate) repayment months].
Average fund: monthly repayment amount = (loan principal/repayment months) (principal-accumulated amount of repaid principal) × monthly interest rate.
Generally speaking, the interest rate formula for calculating interest mainly includes:
Monthly interest rate = annual interest rate/12, daily interest rate = annual interest rate /360.
According to different repayment methods, the algorithm of interest is also different, but the basic algorithm is as follows:
Current month loan interest = the monthly interest rate of the remaining loan principal last month.
Principal paid in the current month = repayment amount in the current month-loan interest in the current month.
Last month's remaining principal = total loan-accumulated repaid principal.
Equal principal and interest repayment method: that is, the sum of loan principal and interest is repaid in equal amount every month. Most banks have adopted this method for housing provident fund loans and commercial personal housing loans. So the monthly repayment amount is the same.
Average capital repayment method: that is, the borrower repays the loan in every installment (month) during the whole repayment period, and at the same time 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.
Pay interest on a monthly basis, and repay the principal at maturity: 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.
Repay part of the loan in advance: that is, the borrower can repay part of the loan amount in advance when applying to the bank. The general amount is an integer multiple of 10000 or 10000. After repayment, the lending bank will issue a new repayment plan, and the repayment amount and repayment period will change, but the repayment method will remain unchanged, and the new repayment period shall not exceed the original loan period.
Repay all the loans in advance: that is, the borrower can repay all the loan amount in advance when applying to the bank. After repayment, the lending bank will terminate the borrower's loan and handle the corresponding cancellation procedures.
Borrow and pay back: interest is calculated daily after borrowing, and interest is calculated daily. You can pay the money in one lump sum at any time without any penalty.
What is the interest rate of bank loans in the same period?
1. What is the interest rate of bank loans in the same period?
The current bank loan interest rate is the interest rate implemented in the current year. At present, the interest rates announced by the People's Bank of China for the same period are as follows: 1. Commercial loan: 65,438+0, the loan term is within one year (including one year), and the interest rate is 4.35%; 2. The loan term is one to five years (including five years) and the interest rate is 4.75%; 3. The loan term is more than five years, and the interest rate is 4.90%.
2. Provident fund loan: 1, the loan term is less than five years (including five years), and the interest rate is 2.75%; 2. The loan term is more than five years and the interest rate is 3.25%.
Major commercial banks will float the above benchmark interest rate, and the specific floating ratio will be determined according to the borrower's qualification, loan type and other factors.
After the borrower knows the loan interest rate, loan term and loan amount, he can use the formula "interest = loan principal loan interest rate loan term" to calculate interest.
: 1. The interest rate of bank loans is the ratio of the interest amount to the average loan occupation in a certain period, which is called interest rate for short.
Its calculation formula is: usually expressed as monthly interest rate and annual interest rate. The relationship between monthly interest rate and annual interest rate is: monthly interest rate × 12= annual interest rate ÷ 12= monthly interest rate.
The relationship between interest and interest rate is: interest = interest rate × principal. If the money is compound interest, then: interest = principal, interest-principal. Where: principal and interest = principal ×( 1 interest rate) term; Or: interest = principal ×.
2. The benchmark interest rate of housing mortgage refers to the unified benchmark interest rate of housing mortgage announced by the People's Bank of China, that is, the highest interest rate of housing mortgage.
When the bank loan interest rate is unstable and fluctuating, the bank can take the benchmark interest rate of housing mortgage loan as the highest current interest rate of bank mortgage loan and lower it by 65,438+00% and implement it.
According to the regulations of the People's Bank of China, the mortgage interest rate of individual housing of commercial banks can be lowered by 15%, but it must be the first self-occupied housing or the first housing loan has been settled.
3. The loan interest rate involves finance and credit. Raising the loan interest rate and expanding the deposit-loan spread will increase the bank's profit, reduce the enterprise's profit and reduce the fiscal revenue; On the contrary, lowering the loan interest rate and reducing the deposit-loan spread will reduce the profits of banks and increase the profits of enterprises, thus increasing fiscal revenue.
The upper limit of loan interest rate is a maximum set by the People's Bank of China, the national financial authority, for the specific implementation standards of loan processing limit and loan ceiling.
How to calculate the bank loan interest rate for the same period?
I. Basic formula for calculating interest The basic formula for calculating interest on savings deposits is: interest = principal × term × interest rate 2. 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 (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). Pay attention to the consistency with the deposit period when using interest rates. 3. Interest starting point 1. The starting point of interest for savings deposits is RMB, and no interest is paid for cents below RMB. 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 period 1, and the calculation of deposit period adopts the method of counting the first number and the last number. 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. V. Calculation of Interest on Foreign Currency Savings Deposits The interest rate of foreign currency savings deposits shall be based on the interest rate published by the People's Bank of China, and the original currency shall bear interest (the secondary currency can be converted into RMB according to the foreign exchange quotation of the day). Its interest-bearing provisions and calculation methods are compared with RMB deposit methods.
