## Mathematical Formula

The standard Equated Monthly Installment (EMI) calculation utilizes the standard amortization formula:

$$EMI = \frac{P \times r \times (1 + r)^n}{(1 + r)^n - 1}$$

Where:
- $P$ = Principal loan amount
- $r$ = Monthly interest rate ($\text{Annual Rate} / 12 / 100$)
- $n$ = Loan tenure in months

- Pure client-side JavaScript execution (no server storage, 100% private).
