Understanding EMI Calculation, Diminishing Balance & Amortization Mechanics
An Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs are structured so that over a fixed number of years, the principal loan amount and accrued interest are completely paid off.
Modern banking and lending institutions predominantly calculate loans using the Diminishing (Reducing) Balance Method. In this structure, interest is calculated solely on the outstanding principal balance remaining at the start of each monthly cycle, rather than on the original full amount. Consequently, in the initial months, a larger proportion of each EMI goes toward paying interest; as the principal reduces over time, each subsequent payment contributes more toward paying down the principal balance.
An Amortization Schedule is an indispensable financial roadmap. It provides month-by-month transparency into how each dollar of your installment is divided between the bank's interest charge and your equity buildup, revealing the exact point at which you transition into paying off more principal than interest.

Frequently Asked Questions (FAQ)
The formula is EMI = [P x r x (1+r)^n] / [(1+r)^n - 1], where P is Principal, r is Monthly Interest Rate (Annual Rate / 12 / 100), and n is Total Number of Monthly Installments.
Because interest is computed on the remaining diminishing balance, any extra principal prepayment directly reduces the outstanding balance for all future months, causing a compounding reduction in interest charges.
