1. Calculation formula of average capital:

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.

Second, the equal interest calculator:

Matching principal and interest repayment method and average capital repayment method are the two most commonly used repayment methods for medium and long-term loans. Equal principal and interest repayment method is equal interest priority repayment method, that is, the amount to be repaid in each period is the same.

Starting from the monthly contribution, the bank collects the interest on the remaining principal first, and then the principal; The proportion of interest in monthly payment decreases with the decrease of residual principal, and the proportion of principal in monthly payment increases with the increase, but the total monthly payment remains 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 amount = 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.
