What is Interest?

Interest is the cost the borrower pays to the lender for using the loan, expressed as a percentage of the principal. It can be charged on a reducing or flat basis, fixed or floating, and is regulated by the RBI's marginal cost of funds-based lending rate (MCLR) and external benchmark norms.

Detailed explanation

Interest explained in plain English

A practitioner's view written for borrowers and advisors — not a textbook definition.

Interest is the cost the borrower pays to the lender for using the loan, expressed as a percentage of the principal. It can be charged on a reducing or flat basis, fixed or floating, and is regulated by the RBI's marginal cost of funds-based lending rate (MCLR) and external benchmark norms.

In practice, Interest is used most often by borrowers, banks. Each of them sees the term from a slightly different angle: borrowers care about protection and outcomes, lenders care about classification and recovery, regulators care about consistency and disclosure.

The legal anchor for Interest is RBI guidelines on interest rates. RBI master directions, the SARFAESI Act 2002, the RDB Act 1993 and the IBC 2016 commonly interplay, depending on the loan size, security and stage of stress.

Why does it matter? Major cost component; revisions trigger EMI changes. For a stressed borrower, getting this concept right early often saves several months of penal interest, legal cost and credit-score damage.

A real example: A ₹40 lakh home loan at 8.75% annual interest on reducing balance. The mechanics may look complex, but the underlying logic — the bank wants closure, the borrower wants a fair outcome — is straightforward once the right framework is in place.

If you are facing a situation involving Interest, the safest first step is a structured case review with a senior ex-banker who has handled comparable matters across banks and ARCs in India.

Where it is used

Where you'll encounter Interest

With borrowers and guarantors

Whenever a loan moves from "Standard" to "stressed", Interest is one of the words that starts appearing in notices, bank emails and lawyers' opinions.

Inside banks and NBFCs

Sanctioning committees, recovery teams and risk officers use Interest to classify accounts, decide provisioning and approve resolution paths.

Before DRT, NCLT and High Courts

Interest appears in pleadings, securitisation applications, OAs, Section 7/9 petitions and SARFAESI writs as part of the dispute record.

In ARC and investor transactions

When stressed loans are sold to ARCs or special-situations investors, Interest is used in term sheets, assignment agreements and due-diligence reports.
