How much is the mortgage interest rate rising by 30%, and how to calculate it?
A 30% increase in mortgage interest rate means a 30% increase on the basis of the benchmark interest rate. For example, based on the current benchmark interest rate of commercial loans for more than five years of 4.90%, after the mortgage interest rate rises by 30%, the actual principal and interest are equal at the conversion rate of 4.90%*( 1+30%)=6.37%, or the monthly payment is calculated at the average capital.

The mortgage interest rate in China is uniformly stipulated by the People's Bank of China. If there is a real estate loan in a bank, the loan should pay interest at the interest rate stipulated by the bank. This interest rate is the mortgage interest rate. 2065438+June 7, 2002, the central bank issued an urgent document to commercial banks, requiring that the lower limit of the floating range of individual housing loan interest rate of commercial banks should still be 0.7 times of the benchmark interest rate.
