Monthly repayment amount = [loan principal × monthly interest repayment months ]=[( 1 interest rate) repayment months-1]

Monthly repayment amount × number of installments-principal = total interest

Matching principal and interest refers to the monthly repayment and interest during the repayment period of a loan.

Equal principal and interest and average capital are not the same concept. Although the monthly repayment amount may be lower than that in average capital at the beginning, the interest paid in the end will be higher than that in average capital, which is also a method often used by banks.

Interest is the use fee of money in a certain period of time, which refers to the monetary interest generated by borrowers lending money or monetary funds, including deposit interest, loan interest and various bonds. Under the capitalist system, the source of interest is the surplus value created by hired workers. The essence of interest is a special transformation form of surplus value and a part of profit.

Interest (interest) is the reward for the owner of the fund to lend the fund, which comes from the producer's use of the fund as part of his business. Refers to the value-added amount brought by monetary funds injected into the real economic sector and returned, and its calculation formula is: deposit period × 100%.

Classification of bank interest:

According to the different nature of banking business, it can be divided into bank types.

Interest receivable refers to the remuneration that the bank will receive from the borrower; This is the fee that the borrower must pay when using the funds.

Interest payable refers to the remuneration paid to depositors by banks to absorb their deposits; It is the price that banks must pay to absorb deposits, and it is also part of the cost of banks.

What are the mortgage repayment methods?

1. Equal repayment of principal and interest: that is, the sum of loan principal and interest is repaid by equal monthly repayment. The housing loan of the house owner adopts the same monthly repayment amount;

Section 2 Allocate the loan amount to each installment (month) evenly throughout the repayment period, and pay it off from the previous trading day to the repayment day.

In this way, the monthly repayment amount decreases month by month.

3. Pay interest on a monthly basis and repay the principal at maturity: that is, the borrower applies for a loan with a term of less than one year (including one year) on the loan maturity date;

4. Repayment of part of the loan in advance: that is, the loan repays part of the loan in advance, which is generally an integer multiple of 65,438+0,000 or 65,438+0,000. If the repayment amount and repayment period are changed, the new repayment period shall not exceed the original loan period.

Repay all loans in advance: that is, the borrower proposes the amount to the bank. After repayment, the lending bank will terminate the borrower's loan and handle the corresponding loan.

2. The more detailed the calculation process of the matching principal and interest loan formula, the better?

Formula monthly repayment amount = [loan principal × monthly interest rate ×( 1 interest rate )× repayment months ]≤[( 1 interest rate )× repayment months-1] Formula calculation: deduce the repayment formula of equal principal and interest, assuming that the total loan amount is a, the monthly interest rate of the bank is β and the total number of installments is m (months). The monthly loan owed to the bank is: a (1β)-x in the first month and [A( 1β)-X] (1β)-x = a (1β) 2-x [/kloc] It can be concluded that the loan owed after the nth month is: a (1β) n-x [1β) (1β) 2? ( 1β) (n- 1β)]

Third, how to calculate the equal principal and interest?

Matching principal and interest refers to a loan repayment method, that is, repaying the same amount of loans (including principal and interest) every month during the repayment period.

Four, how to calculate the equal principal and interest of housing loans?

The calculation formula of monthly repayment amount is as follows:

[loan principal × monthly interest rate ×( 1 monthly interest rate) repayment months ]=[( 1 monthly interest rate) repayment months]

The following example illustrates the equal principal and interest repayment method.

Suppose that the borrower obtains a personal housing loan of 200,000 yuan from the bank, with a loan term of 20 years and a monthly interest rate of 4.2‰, and repays the principal and interest every month. According to the above formula, the sum of monthly principal and interest payable is 1324.33 yuan.

The above results only give the sum of the principal and interest payable each month, so it is necessary to decompose this sum of principal and interest.

Still based on the above example, a month is a cycle.

The balance of the first loan is 200,000 yuan, the interest payable is 200,000× 4.2 ‰ = 840.00 yuan, and the principal is 484.33 yuan.

Outstanding bank loan 1995 15.67 yuan;

The interest payable in the second phase is199515.67× 4.2 ‰ = 837.96 yuan.

Matching principal and interest refers to a repayment method of housing loans, that is, repaying the same amount of loans (including principal and interest) every month during the repayment period, which is different from the average capital.
