📐 Mathematical Formula & Methodology

Monthly Principal & Interest (P&I) Formula: Calculated using standard fixed-rate amortization math where $P$ is principal, $r$ is monthly interest rate ($\text{Annual Rate} / 1200$), and $n$ is total months ($N \times 12$):

M = P \cdot \frac{r(1+r)^n}{(1+r)^n - 1}

PITI Total Payment: $\text{Total Monthly} = M + \text{Property Tax}/12 + \text{Insurance}/12 + \text{PMI}$.
