Mathematical Formula & Amortization Logic
The standard retail banking formula for calculating Equated Monthly Installments (EMI) is:
EMI = [P × R × (1 + R)^N] / [(1 + R)^N - 1]
Where: P = Principal Loan Amount, R = Monthly Interest Rate (Annual Rate / 12 / 100), N = Loan Tenure in Months.
Assumptions
- Fixed annual interest rate throughout loan tenure.
- Compounding occurs monthly on a reducing balance basis.
- Excludes processing fees, insurance, or prepayment penalties.
Common Mistakes
- Entering annual interest rate into monthly compounding rate without dividing by 12.
- Confusing flat interest rate loans with reducing balance loans.
