How to calculate the interest of housing loan

Different repayment methods have different interests. At present, there are two common repayment methods: equal principal and interest and average principal. The specific calculation method of interest is as follows: 1, repayment of equal principal and interest: monthly repayment amount = [loan principal × monthly interest rate× (1interest rate) repayment months ]=[( 1 interest rate) repayment months -650. 2. Equal principal repayment: monthly repayment amount = (loan principal/repayment months) remaining outstanding principal × monthly interest rate.

What are the mortgage repayment methods?

1, average capital

The average capital is the principal to be repaid every month, and the interest of the loan will decrease with the decrease of the principal of the loan, and the total repayment amount will decrease with the decrease of interest. Average capital is more suitable for long-term loans, such as mortgages. If you choose this repayment method, the interest will be less than the equal principal and interest, and it is more cost-effective to repay in advance.

2. Equal principal and interest

Matching the principal and interest is to distribute the principal and interest equally every month to ensure that the monthly repayment amount is equal. This repayment method is used for mortgage loans, with a fixed monthly amount and fixed principal and interest. If you repay the loan in advance, most of the interest will be paid in front of the matching principal and interest, so it is not cost-effective to repay the loan in advance with the matching principal and interest.

4. Repay a loan irregularly.

One-time loan and irregular repayment mean that the borrower can repay all or part of the loan at any time according to his income. This repayment method is very flexible, and the use efficiency of funds is also high, but there will be losses for lenders, so it is difficult to get a repayment method from time to time.

5. Pay the interest in one lump sum and return the principal at maturity.

Paying interest in one lump sum means deducting all interest before the loan and repaying the loan principal in one lump sum after the maturity. If the loan is repaid in advance in this way, it will be unfavorable to the borrower, and the interest paid in advance is not protected by law.

I sold my house and borrowed 400 thousand, 20 years' interest. How to pay off the interest?

At present, the annual interest rate of loans for 5-30 years (including 30 years) announced by the People's Bank of China is 4.9%. According to the trial calculation of the benchmark interest rate, with the interest rate unchanged, the repayment method of equal principal and interest is adopted, and the total interest is 228,266.29 yuan, and the average capital method interest is 65,438+096,865,438+06.67 yuan. Since then, the monthly interest repayment amount has decreased and the principal has increased. (without considering the adjustment of interest rate in the middle)

At present, banks generally adopt the method of equal principal and interest repayment.

Matching principal and interest refers to a repayment method of loans. During the repayment period, the same amount of loans will be repaid every month. No matter how many years the term is, the repayment amount is fixed. This repayment method is relatively suitable for some people who have no stable income, and the pressure will be less.

What is the equal principal and interest method:

Matching principal and interest method is a calculation method of repayment after loan. Under this repayment method, the lender pays the same amount in each installment, and the loan interest will be calculated according to the remaining principal after monthly repayment. In the initial repayment of this loan repayment method, the interest of repayment is greater than the principal, and in the later period, due to the increase of the repaid principal, the interest is reduced, and the repaid principal is redundant. This repayment method is not suitable for those who intend to repay in advance, because under this repayment method, most of the initial repayment is interest and the principal is not much, so it is not cost-effective to repay in advance.

Equal principal and interest method. Under the repayment method of equal principal and interest, the borrower pays the same amount in each installment, paying more interest and less principal at the initial stage, and the interest decreases with the decrease of principal at the later stage, and the repaid principal gradually increases. Under the repayment mode of average capital, the borrower repays the same amount of principal in each period, and the interest on loan repayment will decrease month by month with the increase of repayment of principal, so the borrower's monthly repayment amount will decrease month by month. These two repayment methods are different. The monthly repayment of equal principal and interest remains unchanged, while the monthly repayment of average capital gradually decreases, but the similarity between them is that interest decreases with the decrease of remaining principal.

How to calculate interest on second-hand housing loans

1. Second-hand housing loans have different interest calculation methods due to different repayment methods.

2. If the borrower repays the loan with equal principal and interest, the monthly repayment interest amount is the repayable principal x loan interest rate divided by the number of loan periods. If the applicant repays the loan with the same principal, the monthly repayment interest is the principal payable in the current month x the loan interest rate.

3. The principal of second-hand housing loan accounts for 70% of the transaction price of second-hand housing at most and 30% of the transaction price of second-hand housing at least. The specific interest rate is subject to the interest rate agreed in the loan contract, and so is the number of loan periods.
