An Equated Monthly Installment is the fixed payment amount made to a lender each calendar month. Understanding how your lender calculates interest ensures you don't overpay and helps you capitalize on early principal prepayments.
Standard commercial banking uses the mathematical reducing balance formula:
Never accept an auto loan or personal loan quote without verifying if it is reducing or flat:
When you make an extra payment earmarked for principal, it immediately reduces the balance against which the lender computes next month's interest. This creates a compounding savings cascade throughout the remaining loan term.
In standard amortization, interest charges are highest when the outstanding principal is highest. Early monthly installments consist mostly of interest. As the balance shrinks, each subsequent payment allocates more to principal.
