Equal principal and interest method: (equal monthly repayment)

Monthly repayment amount = principal * monthly interest rate *( 1+ monthly interest rate) n/[( 1+ monthly interest rate) n- 1]

Where: monthly interest rate = annual interest rate/12, n represents the number of loan months, and n represents the power of n, for example, 120 represents the power of 120 (loan 10, 120 months). Note: When calculating (1+ monthly interest rate) n- 1, you must first calculate what is in brackets, and then multiply and subtract 1.

Substitute data into the formula:

200000 * 3.375% * ( 1+3.375%) 120/[( 1+3.375%) 120- 1] = 6878.65438.

I think the interest rate is very high this month. Will it be 3.375‰ (3.375 ‰)? If so, the calculated monthly repayment amount is 2029.56 = 2029.66 yuan.

If it is simply a calculation problem, it is also possible.
