How to calculate the principal of mortgage interest?
Loan interest is a kind of principal interest that the buyer borrows from the bank and pays at the interest rate stipulated by the bank. The calculation formula of interest is:
Interest = principal × interest rate× deposit period (i.e. time).
The calculation of mortgage interest will be different because of the different loan methods and mortgage repayment methods.
According to the different repayment methods of mortgage, the calculation of mortgage interest can be divided into two calculation methods: equal principal and interest and average capital.
How to calculate the mortgage interest? First of all, we must understand the basic knowledge of interest.
I. The interest rate conversion formula for RMB business is (note: common for deposits and loans):
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 product interest method and 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 carries out transaction-by-transaction interest calculation 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.
The central bank gives financial institutions the right to choose which formula to use. Therefore, the parties and financial institutions can agree on this in the contract.

Calculation method
Tool description
1, operation steps:
Step 1: First, choose whether your repayment method is average capital or equal principal and interest, and fill in the commercial loan term, loan amount and actual loan interest rate;
Step 2: Choose whether to display repayment details, and click "Calculate" to get detailed information such as monthly payment amount, total loan interest and total repayment amount.
point out
1. Commercial loans are loans used to supplement the working capital of industrial and commercial enterprises. Generally, they are short-term loans, with a term of 9 months and no more than one year at most, but there are also a few medium-and long-term loans. This kind of loan is the main part of commercial bank loans, generally accounting for more than one-third of the total loans.
2. Calculate the monthly payment, total interest and total repayment of commercial loans when choosing the repayment method of average capital and equal principal and interest.
According to the general mortgage repayment formula, it can be divided into two types:
I. Calculation formula of equal principal and interest:
Calculation principle: from the beginning of monthly contribution, the bank first charges interest on the remaining principal, and then charges the principal; The proportion of interest in monthly contributions decreases with the decrease of residual principal, and the proportion of principal in monthly contributions increases with the increase, but the total monthly contributions remain unchanged.
It should be pointed out that:
1, the maximum amount of urban provident fund loans should be combined with local conditions;
2. For residents who have borrowed money to buy a house but whose per capita area is lower than the local average, and then apply for buying a second set of ordinary self-occupied housing, the preferential policies for buying ordinary self-occupied housing with the first set of loans shall be implemented mutatis mutandis.
Second, the average capital calculation formula:
Monthly repayment = monthly principal, monthly principal and interest.
Monthly principal = principal/repayment months
Monthly principal and interest = (principal-total accumulated repayment) x monthly interest rate
Calculation principle: the amount of principal returned every month is always the same, and the interest will decrease with the decrease of the remaining principal.
Formula description
According to the above formula
Principal: total loan amount
Number of repayment months: loan term X 12. For example, the repayment period of a 10-year loan is 10X 12= 120 months.
Monthly interest rate: monthly interest rate = annual interest rate/12.
Annual interest rate: that is, in the hot topic of mortgage discussion now, the basic interest rate is 30% off and 15% off.
Cumulative repayment amount: the cumulative repayment amount in the first month of average capital repayment law is 0.
For example: 2009 annual interest rate table
Basic annual interest rate: 5.94%
15% annual interest rate: 5.05%
30% annual interest rate: 4. 16%
Annual interest rate of provident fund: 3.87%
explain
Mr. Wang borrowed 400,000 yuan from the bank to buy a house and paid it off in 20 years. The bank gave Mr. Wang a 30% interest rate discount.
If the annual interest rate is changed to monthly interest rate, the monthly interest rate is 4.16%/12 = 0.00347.
Matching principal repayment method:
Monthly principal = 400,000/240 =1.67
Monthly principal and interest = 400,000× 0.00347 =1388.
Repayment in the first month =1.671388 = 3054.67 (yuan)
