I. Calculation formula of equal principal and interest:
[loan principal × monthly interest rate ×(65438+ 10 monthly interest rate) repayment months ]=[(65438+ 10 monthly interest rate) repayment months-1]
Second, the average capital calculation formula:
Monthly repayment amount = (loan principal ÷ repayment months) (principal-accumulated amount of repaid principal) × monthly interest rate, where the symbol represents power.
For example, suppose the principal is 10000 yuan, the bank loan is 10 year, and the benchmark interest rate is 6.65%, and compare the differences between the two loan methods.
Second, how to calculate the bank loan formula?
Matching principal and interest repayment method:
Monthly loan amount = [loan principal × monthly interest rate ×( 1 interest rate )× repayment months ]=[( 1 interest rate )× repayment months]
Monthly interest payable = loan principal × monthly interest rate × [( 1 interest rate )× repayment months -( 1 interest rate) ÷ [( 1 interest rate )× repayment months-1]
Monthly repayment principal = loan principal × monthly interest rate ×(65438+ 10 interest rate) (repayment month serial number-1)÷[(65438+ 10 interest rate) repayment months-1]
Total interest = repayment months × monthly repayment amount-loan principal
Average capital repayment method:
Monthly loan amount = (loan principal ÷ repayment months) (loan principal-accumulated repaid principal) × monthly interest rate.
Monthly repayable principal = loan principal ÷ repayment months
Monthly interest payable = residual principal × monthly interest rate = (loan principal-accumulated principal repayment) × monthly interest rate
Monthly decreasing amount = monthly repayable principal × monthly interest rate = loan principal ÷ repayment months × monthly interest rate.
Total interest = [(total loan amount ÷ repayment months × monthly interest rate) total loan amount ÷ repayment months × (1 monthly interest rate)] ÷ 2× repayment months-total loan amount.
Monthly interest rate = annual interest rate ÷12 154 =15 ×15 (the fourth power of15, that is, the product of four15).
3. How is the bank loan calculated?
That depends on when you borrowed the money. Banks rely on loans to make a living. Before last year, when the interest rate was not adjusted, the interest rate of your loan was similar to the principal. That is to say, your loan for 30 years, after 30W30, you have to pay back about 60W. Now the interest rate has been lowered, the bank has made a 30% discount, and the interest rate of deposit and loan business has been reduced a lot.
4. What are the formulas for calculating the interest rate of bank loans?
There is the following formula: 1, monthly interest rate: that is, monthly interest, and its 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, and its calculation method is: daily interest rate = annual interest rate ÷. The calculation method of interest based on the annual interest period is: annual interest rate = interest ÷ principal ÷ time × 100%. 4. Annualized interest rate: refers to discounting the internal rate of return of products to the annual interest rate, which is quite different from the calculation method of annual interest rate. Assuming that the return period of a wealth management product is one year and the rate of return is B, the annualized interest rate R is calculated as r = (1b) A- 15, and the calculation formula of equal principal and interest is [loan principal × monthly interest rate× (1monthly interest rate) repayment months]; [(65438) Bank loan refers to an economic behavior in which banks lend funds to people in need of funds at a certain interest rate according to national policies and return them. Generally, you need a guarantee, a house mortgage, proof of income and good personal credit information before you can apply. Moreover, in different countries and different development periods of a country, the types of loans classified according to various standards are also different. For example, industrial and commercial loans in the United States mainly include ordinary loan limits, working capital loans, standby loan commitments, and project loans. In Britain, industrial and commercial loans mostly take the form of discounted bills, credit accounts and overdraft accounts. According to different classification standards, there are many types of bank loans. For example, 1 can be divided into short-term loans, medium-term loans and long-term loans according to different repayment periods; 2. According to different repayment methods, it can be divided into demand loans, term loans and overdrafts; 3. According to the different purposes or objects of the loan, it can be divided into industrial and commercial loans, agricultural loans, consumer loans and securities broker loans. ; 4. According to the different loan guarantee conditions, it can be divided into bill discount loan, bill mortgage loan, commodity mortgage loan and credit loan. 5. According to the loan scale, it can be divided into wholesale loans and retail loans; 6. According to the different ways of interest rate agreement, it can be divided into fixed interest rate loans and floating interest rate loans, and so on. Short-term loans refer to loans with a loan term of 1 year (inclusive). Short-term loans are generally used for the liquidity needs of the borrower's production and operation. The currencies of short-term loans include RMB and major convertible currencies of other countries and regions. The term of short-term working capital loans is generally about half a year, and the longest is no more than one year; Short-term loans can only be extended once, and the extension period cannot exceed the original period. The loan interest rate is determined according to the interest rate policy formulated by the People's Bank of China and the floating range of the loan interest rate, according to the nature, currency, use, method, term and risk of the loan, among which the foreign exchange loan interest rate is divided into floating interest rate and fixed interest rate. The loan interest rate is indicated in the loan contract, which customers can check when applying for a loan. There is a penalty interest for overdue loans. The advantages of short-term loans are relatively low interest rates and relatively stable capital supply and repayment. The disadvantage is that it cannot meet the long-term capital needs of enterprises. At the same time, because short-term loans use fixed interest rates, the interests of enterprises may be affected by interest rate fluctuations.
