The amount paid toward interest and principal (13,894.67 + 1,579.84 = 15,474.51) equals
the total of 12 monthly payments (12 × 1,289.54 = 15,474.51). The remaining balance equals
the initial mortgage, less the amount applied toward principal (180,000 - 1,579.84 =
178,420.16).

The amount paid toward interest and principal (13,767.79 + 1,706.69 = 15,474.51) equals the
total of 12 monthly payments (12 × 1,289.54 = 15,474.51). The remaining balance equals the
initial mortgage less the amount applied toward principal (180,000 - 1,579.84 - 1,706.69 =
176,713.49). More money is applied to principal during the second year rather than the first
year. The succeeding years continue in the same fashion.
