Home Loan Basics

A home loan EMI is calculated from three inputs: principal, interest rate, and tenure. Extending tenure lowers the EMI but sharply increases total interest paid — stretching a loan from 15 to 25 years might cut the EMI by roughly a third, while nearly doubling the total interest paid over the loan's life. Tenure should be chosen based on genuine affordability, not just to minimize the monthly number.

Floating rate loans move with the broader interest rate environment (linked to an external benchmark like the repo rate in India), while fixed rates stay constant for a period but are usually set higher upfront to compensate the lender for that certainty. Most long-tenure home loans in India are floating rate, since a fixed rate over 15-20 years is rare and typically comes at a real premium.

Prepayment — paying extra toward principal beyond the scheduled EMI — is one of the highest-value moves available on a home loan, especially in the early years when most of each EMI goes to interest rather than principal. Even a modest annual lump-sum prepayment (like a bonus) can meaningfully cut both total interest paid and the effective loan tenure.

Before signing, look past the headline interest rate to the processing fee, prepayment/foreclosure charges (many loans now waive these for floating-rate loans by regulation, but it's worth confirming), and whether the rate is linked transparently to an external benchmark rather than an opaque internal one that the lender can adjust with less visibility.
