The Actuarial Amortization Formula
Equated Monthly Installments are calculated using the universal reducing-balance loan amortization formula:
The total amount borrowed from the lender.
Annual rate divided by 12 months, then by 100.
Number of monthly payments (Loan years × 12).

Key Financial Strategies for Borrowers
Impact of Extra Principal Repayments
Because interest is calculated monthly on the remaining balance, making even small lump-sum payments directly against the principal substantially reduces overall interest and cuts months or years off your mortgage.
Fixed Rate vs. Variable Rate Amortization
This schedule reflects a fixed-rate loan where the interest rate remains constant. For variable-rate mortgages, your lender will recalculate the monthly EMI whenever benchmark central bank rates change.

Frequently Asked Questions
What is an EMI?
EMI stands for Equated Monthly Installment. It is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs are applied to both interest and principal each month so that over a specified number of years, the loan is fully paid off.
How is loan EMI calculated?
EMI is calculated using the actuarial amortization formula: EMI = [P × r × (1 + r)^n] / [(1 + r)^n − 1], where P is the loan principal, r is the monthly interest rate (annual interest rate divided by 12 and then 100), and n is the total number of monthly payments.
How does the proportion of principal and interest change over time?
In the early months of a loan, a larger portion of each EMI goes toward paying interest because the remaining balance is high. As the balance decreases over time, less interest accrues, and a larger portion of each payment goes toward paying down the principal balance.
Does paying extra reduce total interest?
Yes. Any additional repayment made directly against the loan principal reduces the outstanding balance immediately, which lowers subsequent monthly interest charges and shortens the total loan tenure.
