What an EMI is

An equated monthly installment is a fixed payment that covers interest due that month plus some principal. Over the term, the interest portion shrinks and the principal portion grows if the rate is fixed.

Why early payments feel “all interest”

Interest is charged on the outstanding balance. At the start the balance is highest, so more of each payment services interest. That is normal amortization — not necessarily a mistake in the calculator.

Variable rates

Products tied to an index (for example Euribor + spread) change over time. A fixed-rate EMI tool can only approximate those with an assumed average rate. Read the lender’s APR and fees for real cost.

FAQ

Does paying extra principal help?
Often yes, by reducing future interest, but prepayment rules vary. Confirm with your contract.
