The rate of interest rate increase does not necessarily change every year. If you choose the LPR floating interest rate, the LPR interest rate will be adjusted once a year. If you choose LPR fixed interest rate, the interest will be calculated according to the fixed interest rate during the loan period.

Extended data:

Interest rate bonus refers to the value of interest rate bonus. For example, the LPR interest rate is 4.8%, and after a certain upward adjustment, the final interest rate is 5.3%, so the interest rate plus point is 0.5% or 50BP. After the user converts the mortgage interest rate into LPR interest rate, the interest rate will be raised to a fixed value and will not change during the loan period. The range of interest rate increase means that when banks apply for loans, they will add or subtract basis points from the LPR interest rate, and one basis point is 0.0 1%, so 100 basis points is equal to 1%. When applying for a loan, different banks give different basis points for addition and subtraction. Generally, the more points are added, the higher the actual loan interest rate of users.
