Now loans have become more and more popular, because it allows people to spend in advance and repay in installments later, greatly reducing the economic burden. In this process, only some loan costs need to be properly paid, and the amount of this loan cost needs to be calculated by the loan interest rate. So, what is the formula for calculating the loan interest rate? Let's take a look together.
I. Calculation formula of loan interest rate
1, daily interest rate = monthly interest rate /30 days = annual interest rate /360 days;
2. Monthly interest rate = daily interest rate for 30 days = annual interest rate/12 months;
3. Annual interest rate = monthly interest rate 12 months = daily interest rate of 360 days;
4. Interest = loan principal loan interest rate loan term;
5. Under the average capital method, interest = the loan interest rate of the remaining principal to be repaid;
6. Under the equal principal and interest method,
Monthly interest = the monthly interest rate of the remaining loan principal.
Monthly repayment amount = [loan principal × monthly interest rate ×( 1 interest rate) repayment months ]≤[( 1 interest rate) repayment months-1],
If the repayment period is 6 and the monthly interest rate is 1%, then (11%) 6 =1.01.0165438.
Second, for example.
Assuming that the loan principal is 6000 yuan, the loan term is 6 months, and the monthly interest rate is 1%, then:
1, average capital model
Monthly repayment amount =6000/6= 1000 yuan,
The first month loan interest =6000 1%=60 yuan;
The loan interest of the next month = (6000-1000)1%= 50 yuan;
Third month interest =(6000-2000) 1%=40 yuan;
The fourth month interest =(6000-3000) 1%=30 yuan;
The fifth month interest =(6000-4000) 1%=20 yuan;
Interest of the 6th month = (6000-5000)1%=10 yuan.
2. Under the equal principal and interest method
Monthly repayment amount = (60001%1.06)/(1.06-1) =1035.29 yuan,
The first month loan interest =6000 1%=60 yuan, and the remaining loan principal = 6000-(1035.29-60) = 5024.71yuan;
The loan interest of the next month is 5024.711%= 50.25 yuan, and the remaining loan principal is 5024.71-(1035.29-50.25) = 4039.67 yuan;
Conversely, the interest of the sixth month = 10.25 yuan.
The above is about the "loan interest rate calculation formula", I hope it can help you.
How to calculate the loan interest rate?
According to the notice of the central bank:
Central bank loan benchmark interest rate:
(1) Short-term loan: within one year (including one year), and the adjusted interest rate is 4.35.
(2) Medium and long-term loans: the adjusted interest rate is 4.75 for one to five years (including five years); The adjusted interest rate for more than five years is 4.90.
(3) Personal housing provident fund loan: after five years (including five years), the menu adjustment interest rate is 2.75; The adjusted interest rate for more than five years is 3.25.
Agricultural Bank, the interest rate of short-term loans (within six months, including six months) is 4.35%; The loan interest rate for half a year to one year (including one year) is 4.35%. The loan interest rate for one year to three years (including three years) is 4.75%, and the loan interest rate for more than five years is 4.9%.
If it is a provident fund loan, the loan interest rate for less than five years (including five years) is 2.75%; The loan interest rate for more than five years is 3.25%.
The loan interest rate is the interest rate charged by banks and other financial institutions to borrowers when they issue loans. It is mainly divided into three categories: the loan interest rate of the central bank to commercial banks; The loan interest rate of commercial banks to customers; Interbank lending rate
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.

How to calculate the bank loan interest rate?
Calculation method of bank loan execution interest rate: execution interest rate = benchmark interest rate × (interest rate floating value 1), where the interest rate is negative. The loan interest rate of the Bank is based on the benchmark loan interest rate published by the People's Bank of China, and fluctuates on the basis of the corresponding term and interest rate. The interest rate actually released by the bank is the executive interest rate. Each bank's loan type and loan term are different, and the execution interest rate is also different. The lowest interest rate is the provident fund loan interest rate. In the past few years, the commercial loan interest rate of mortgage lenders in various banks may have a certain interest rate discount, such as 15% discount, which means that the interest rate will drop 15%, the floating value of interest rate will be-15%, and the long-term housing loan execution interest rate will be 4. 165%. At present, commercial loans generally rise by 20% today, with a floating interest rate of 20% and a long-term housing loan execution rate of 5.88%. And various consumer and commercial loans, if the repayment method is different, the interest rate is also different.
How to calculate the loan interest rate
(1) The interest rate conversion formula for RMB business is (note: common for deposits and loans):
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
