An Equated Monthly Installment, or EMI, is the fixed amount you pay each month toward a loan until it is fully repaid. Understanding how it is calculated helps you see through advertised interest rates and compare offers on equal footing.
The three numbers that determine your EMI
- Principal — the amount you are borrowing.
- Interest rate — the annual rate charged, usually converted to a monthly rate for the calculation.
- Tenure — how many months you have to repay the loan.
Why a longer tenure is not automatically better
Stretching a loan over more months lowers the monthly payment, which feels more affordable, but it increases the total interest paid over the life of the loan because interest accrues on the outstanding balance for a longer period. A shorter tenure means higher monthly payments but a lower total cost.
What to compare between loan offers
Do not compare offers by monthly payment alone. Two loans with the same EMI can have very different total interest costs if their tenures differ. Always look at total interest paid over the full term, not just the monthly figure.
A quick sanity check
Before committing to a loan, calculate the EMI yourself using the actual rate and tenure quoted, rather than relying on a lender's rounded estimate. Small differences in the interest rate compound meaningfully over a multi-year loan.
