The Mathematical Formulation of Equal Periodic Payments

Fixed-rate amortized debt distributes equal payments across \(n\) periods. Monthly interest is computed by multiplying the periodic interest rate \(r = \frac{APR}{12}\) by the remaining principal balance. Because principal reduces slowly initially, early payments consist overwhelmingly of non-equity interest.

Monthly EMI Formula

EMI = [P × r × (1 + r)n] / [(1 + r)n − 1]
