Marine Loan Payment & Financing Formula

M=P×[r(1+r)n(1+r)n1],P=Price+TaxDown PaymentM = P \times \left[ \frac{r(1+r)^n}{(1+r)^n - 1} \right], \quad P = \text{Price} + \text{Tax} - \text{Down Payment}

Computes the fixed periodic monthly payment (M) on a boat loan based on total financed principal (P), periodic monthly interest rate (r), and total amortization tenure in months (n).
