The repayment method of the loan is:

(1) equal repayment method. During the loan period, the borrower repays the loan principal and interest in full with the same repayment amount every month. The calculation formula is as follows:

In which: R- monthly repayment amount;

P- loan principal;

I- monthly loan interest rate;

N— loan term (year).

(2) Average capital mode. During the loan period, the borrower repays the loan principal in equal amount every month, and the interest decreases month by month. The calculation formula is as follows:

Monthly repayment amount =P/(n× 12) Total amount of remaining loans× i.

In which: p-loan principal;

I- monthly loan interest rate;

N— loan term (year).

(3) Free repayment method:

Free repayment means that the principal determines the minimum repayment amount of each loan after consulting with the borrower to determine the loan amount and term, and the borrower is free to choose the monthly repayment amount under the condition of not less than the minimum repayment amount. The calculation formula of the minimum monthly repayment amount:

1. Formula for calculating the minimum monthly repayment amount with a loan term of five years (including five years):

In which: r- the minimum monthly repayment amount (reserved to RMB, rounded to the whole number);

P- loan principal;

I- monthly loan interest rate;

N— loan term (year).

2. The formula for calculating the minimum monthly repayment amount with a loan term of more than five years (excluding):

The minimum monthly repayment amount of the borrower = the loan principal that should be repaid at least before the loan maturity date (excluding), the monthly repayment amount calculated by the equal monthly repayment method, and the interest generated by each installment of the loan principal that should be repaid in the last installment.

In which: r- the minimum monthly repayment amount (reserved to RMB, rounded to the whole number);

P- loan principal;

P0 —— the loan principal that should be repaid before the last installment according to the depreciation of the building;

I- the monthly interest rate of the loan (used to calculate the minimum monthly repayment);

N— loan term (year).

Note: P0 is determined on the basis of comprehensive consideration of several factors such as housing depreciation rate, loan risk and interest rate risk.

Second, how to calculate the amount of provident fund loans?

The loan amount of housing provident fund can only be determined by comprehensive calculation.

The calculation of provident fund loan amount should be determined according to four conditions: repayment ability, proportion of house price, balance of housing provident fund account and maximum loan amount, and the minimum value calculated by the four conditions is the maximum loanable amount of the borrower.

The calculation method is as follows:

According to the repayment ability calculation formula, {(total monthly salary of the borrower and monthly payment of the borrower's unit housing provident fund) × repayment ability coefficient-total monthly repayment amount of the borrower's existing loan }× loan period (month), {(total monthly salary of both husband and wife and monthly payment of their respective unit housing provident fund )× repayment ability coefficient-total monthly repayment amount of both husband and wife }× loan period (month). Among them, the repayment ability coefficient is 40%, and the total monthly salary = the monthly contribution of the provident fund ÷ (the ratio of unit contribution to individual contribution);

According to the calculation formula of house price, loan amount = house price × loan ratio, in which the loan ratio is determined according to the different types of houses purchased, built and repaired and the number of mortgage loans;

According to the account balance, if an employee applies for a housing provident fund loan, the loan amount shall not be higher than 10 times of the housing provident fund account balance when the employee applies for a loan (if the spouse housing provident fund is used to apply for a housing provident fund loan at the same time, it is the sum of the employee's and spouse's housing provident fund account balances), and if the housing provident fund account balance is less than 20,000, it shall be calculated as 20,000;

According to the maximum amount, the maximum loan amount for applying for housing provident fund loans with my own housing provident fund is 400,000 yuan, the maximum loan amount for applying for housing provident fund loans with my spouse's housing provident fund is 600,000 yuan, the maximum loan amount for applying for housing provident fund loans with my spouse's housing provident fund is 500,000 yuan, and the maximum loan amount for applying for housing provident fund loans with my spouse's housing provident fund is 700,000 yuan.

3. What is the formula for calculating the loan amount of housing provident fund?

Roughly divided into:

(1) Loan amount = (monthly deposit amount of housing provident fund × 12× personal account balance of future housing provident fund )× 2.

(2) The retirement age is subtracted from the current age to calculate the number of years that can be paid in the future. At present, the retirement age in Changsha is calculated according to the age of 60 for male employees and 50 for female employees.

1, calculate the loan amount according to the repayment ability.

The calculation formula is: [(total monthly salary of the borrower, monthly contribution of the housing accumulation fund of the borrower) × repayment ability coefficient-total monthly repayment amount of the borrower's existing loan ]× loan period (month). ?

Step 2 Use your spouse's quota

The calculation formula is: [(total monthly salary of both husband and wife, monthly contribution of housing provident fund of both husband and wife's work units) × repayment ability coefficient-total monthly repayment amount of existing loans of both husband and wife ]× loan period (month)

Among them, the repayment ability coefficient is 40%, and the total monthly salary = the monthly contribution of the provident fund ÷ (the ratio of unit contribution to individual contribution).

3. The loan amount calculated according to the house price

The calculation formula is: loan amount = house price × loan ratio.

4. The loan amount is calculated according to the high loan limit.

If I use my housing provident fund to apply for a housing provident fund loan, the loan ceiling is 400,000 yuan; At the same time, if the spouse's housing provident fund is used to apply for housing provident fund loans, the loan ceiling is 600,000 yuan. I use my housing provident fund to apply for a housing provident fund loan. If I pay the housing provident fund normally when applying for a loan, the loan ceiling is 500,000 yuan; At the same time, if the spouse's housing provident fund is used to apply for a housing provident fund loan, and the spouse or I normally pay a supplementary housing provident fund when applying for a loan, the loan ceiling is 700,000 yuan.

Fourth, how to calculate the amount of provident fund loans?

The calculation of provident fund loan should be based on four conditions: repayment ability, the proportion of housing price, the balance of housing provident fund account and the maximum loan amount, that is, the maximum loanable amount of the lender.

Calculate the monthly income of oneself and the same applicant: monthly income = monthly contribution of individual housing provident fund ÷ contribution ratio of housing provident fund;

Calculate the monthly income of both parties of the maximum loanable amount, the monthly income of retired employees and their children and other applicants, the same below), the remaining amount after deducting the monthly living expenses of at least 400 yuan, and then divide it by the monthly repayment amount of the loan per 10,000 yuan during the loan application period, which is the maximum loanable amount.
