\text{SAC: } A = \frac{P}{n}, \quad PMT_t = A + (P - (t-1)A) \cdot i; \qquad \text{Price: } PMT = P \cdot \frac{i(1+i)^n}{(1+i)^n - 1}In the SAC system, principal amortization is constant every month, resulting in continuously decreasing payments. In the Price system, monthly payments are constant, amortizing principal slower and resulting in significantly higher lifetime interest.
