Yearly schedule

Year Paid this year Principal Interest Balance

Equal instalment keeps the payment flat with more interest up front; equal principal repays a fixed amount of principal each month, so payments decline and total interest is lower. Figures are computed in yuan; banks round to the cent and absorb the remainder in the final period, so per-period detail can differ by a few cents.
