Will not decrease. The loan amount of provident fund should be determined according to four conditions: repayment ability, proportion to house price, balance of housing provident fund account and maximum loan amount, among which the minimum value calculated by the four conditions is the maximum loanable amount of the lender.

Provident fund loan amount and its calculation method;

[(the total monthly salary of the borrower+the monthly contribution of the housing provident fund of the borrower) × repayment ability coefficient-the total monthly repayment amount of the borrower's existing loan ]× loan term (month);

Use of spouse's quota: [(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);

The repayment ability coefficient is 40%, and the total monthly salary = the monthly contribution of the provident fund ÷ (unit contribution ratio+individual contribution ratio);

The calculation formula of the loan amount calculated according to the house price is: loan amount = house price × loan ratio.
