I got a housing loan of 7, yuan in China Construction Bank, with monthly interest of 6.6 and annual interest of 7.26. The mortgage payment will be paid off in ten years. How much is the monthly repayment? The loan term is 1 years, and the annual interest rate is 7.26%, with equal repayment of principal and interest: the monthly payment is 822.17 yuan, with a total repayment of 98,66.45 yuan, and the accumulated interest for 1 years is 28,66.45 yuan under the assumption that the interest rate remains unchanged.

but there is a contradiction between the monthly interest and the annual interest you provided. Monthly interest rate (unit: ‰) = annual interest rate (%) ÷ 12× 1

Therefore, when the interest rate was 7.26%, the monthly interest rate was 7.26% ÷ 12× 1 = 6.5 ‰.
