First, the basic knowledge of interest calculation
(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
These three formulas are essentially the same, but because the interest rate conversion is only 360 days a year, when calculating the actual daily interest rate, it will be calculated as 365 days a year, and the result will be slightly biased. Which formula is used specifically, the central bank gives financial institutions the right to choose independently. Therefore, the parties and financial institutions can agree on this in the contract.
(3) 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.
(4) 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 defaulter according to the contract signed with the parties is called bank penalty interest.
(V) loans overdue liquidated damages: penalties for the defaulting party with the same nature as penalty interest.
(six) the formulation and filing of interest calculation methods
The interest-bearing settlement rules and methods for deposit and loan business formulated by national commercial banks as legal persons shall be reported to the head office of the People's Bank of China for the record, and the customers shall be informed; Regional commercial banks and urban credit cooperatives should be reported to the branches of the People's Bank of China and the central branch of the provincial capital for the record, and inform customers; County rural credit cooperatives as legal persons may, according to the actual situation of the county rural credit cooperatives, formulate the rules for interest calculation and settlement and the interest-bearing measures for deposit and loan business, and report them to the branch of the People's Bank of China and the central branch of the provincial capital for the record, and the rural credit cooperatives as legal persons shall notify the customers.
How about the house interest calculator?
The housing interest calculator is as follows:
The house interest device is calculated according to the repayment method, in which the calculation formula of the equal principal and interest is: monthly repayment amount = loan principal x monthly interest rate x( 1 interest rate) ÷( 1 interest rate) repayment months-1. The calculation formula of average capital is: monthly repayment amount = (loan principal ÷ repayment months) remaining unpaid principal x monthly interest rate.
How to get a cost-effective housing loan?
First, the mortgage jumped ship. Simply put, the bank helps customers find a guarantee company, pays off the bank's money, and then applies for a loan. If your bank can't give you a 30% mortgage interest rate, you can jump ship to find the most affordable bank.
Second, adjust the interest rate monthly. 10 years ago, many commercial banks launched fixed-rate mortgage business, but when the business was launched, it was in the channel of rising interest rates, so interest rates fluctuated greatly. As long as the central bank raises interest rates once, its advantages will emerge. However, once interest rates are cut, property buyers will suffer.
Third, the provident fund is transferred to repay the loan. When applying for a portfolio loan, we should use the provident fund as much as possible to extend the loan life. In addition, while enjoying low interest rates, F should try to reduce the monthly payment of provident fund and shorten the life of commercial loans, which is within the economic affordability. Try to increase the monthly repayment amount of commercial loans.
Fourth, repay the loan in advance to shorten the term. Before repaying the loan, it is best to calculate an account, because not all loans are cost-effective. For example, if the repayment period exceeds half, or the principal in the monthly repayment amount is greater than the interest, there is no need to repay in advance.
Down payment for buying a house
In fact, the down payment for the first suite is the same all over the country, that is, the minimum is 30% of the total house price. Therefore, when the total house price is different, the actual down payment for house purchase is also different.
For the purchase of multiple suites, such as two suites and three suites, due to the influence of the purchase restriction policy, different regions have different requirements for the down payment ratio when purchasing these properties, but they are generally higher.
