How EMIs Work: Understanding Your Monthly Loan Repayment

An EMI (Equated Monthly Instalment) is the fixed amount you pay your lender every month until a loan is fully repaid. It's "equated" because the amount stays the same each month — but what that amount is actually paying for changes a lot over the life of the loan.

Every EMI is part interest, part principal

Each instalment repays two things at once: interest on the amount you still owe, and a portion of the original amount borrowed (the principal). Early in the loan, most of your EMI goes toward interest, because the outstanding balance is still high. As you keep paying, the balance shrinks, so less of each EMI is interest and more goes toward principal — even though the EMI itself doesn't change.

Why tenure matters more than it looks

A longer tenure lowers your EMI, which is why it's tempting to stretch a loan out. But a longer tenure also means you pay interest for longer, so the total interest paid over the life of the loan is higher — often significantly. A shorter tenure raises the EMI but reduces total interest paid. There's no universally "right" tenure; it depends on what monthly amount is comfortable against your income, and how much the extra interest cost of a longer tenure is worth to you.

What changes your EMI after disbursal

On a fixed-rate loan, your EMI stays constant for the full tenure. On a floating-rate loan, your EMI (or your tenure, depending on the lender's policy) can change if the benchmark interest rate moves. It's worth checking which type of rate you're being offered before you commit — see our guide on fixed vs. floating rates for more.
