What is an EMI?
EMI stands for Equated Monthly Installment — a fixed payment you make every month to repay a loan, made up of a principal portion and an interest portion. Early in the loan, more of each EMI goes toward interest; later on, more goes toward principal, even though the total payment stays the same each month.
How is EMI Calculated?
Lenders use 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 ÷ 12 ÷ 100), and n is the number of monthly installments. For example, a ₹10,00,000 loan at 8.5% annual interest over 5 years works out to roughly ₹20,517 a month — our calculator does this instantly and also shows you the full month-by-month breakdown.
Understanding Your Amortization Schedule
An amortization schedule shows exactly how each EMI splits between interest and principal over the life of the loan. Reviewing it can help you decide whether a lump-sum prepayment makes sense — prepaying early, while the interest portion is highest, generally saves more total interest than prepaying later.
Home Loan vs. Personal Loan vs. Car Loan EMI
The EMI formula is identical across loan types — what differs is the typical interest rate and tenure. Home loans usually carry the lowest rates (often 8–9% p.a.) and longest tenures (up to 30 years), since they're secured against property. Personal loans are unsecured and carry higher rates (10–24% p.a.) with shorter tenures. Car loans typically sit in between, secured against the vehicle itself.
Tips Before You Take a Loan
As a rough guideline, many financial planners suggest keeping all EMIs (combined) under 40% of your monthly take-home income. It's also worth comparing the total interest paid across different tenures — a longer tenure lowers your monthly EMI but increases total interest paid over the life of the loan.
