What is an EMI?
EMI stands for Equated Monthly Installment — the fixed amount you pay a lender every month until your loan is fully repaid. Each EMI has two components: the principal portion (which reduces your loan balance) and the interest portion (the lender's charge).
In the early years of a loan, a larger share of your EMI goes toward interest. As the loan progresses, the principal share increases. This is called amortization.
The EMI Formula
Banks calculate EMI using the formula: EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate divided by 12 and 100), and n is the number of monthly installments.
For example, a ₹10,00,000 loan at 9% annual interest for 5 years (60 months) gives a monthly rate of 0.75% and an EMI of approximately ₹20,758.
How Tenure Affects Your EMI
Longer tenures mean smaller EMIs but much higher total interest. A 20-year home loan at 8.5% on ₹50,00,000 has an EMI of about ₹43,391 and total interest of over ₹54,00,000 — more than the loan itself.
Shortening your tenure by even 2–3 years can save lakhs in interest. Use our EMI calculator to compare different tenure options before you commit.
Tips to Reduce Total Interest
Make prepayments whenever you have surplus cash — prepayments directly reduce the principal and cut future interest. Even one extra EMI payment per year can shorten your loan by several months.
Compare interest rates across lenders before borrowing. A difference of even 0.5% on a large home loan can mean several lakhs in savings over the loan's life.
