My floating home loan rate just went up. What does that actually cost me?
No Sign-Up. No Paywall.
When a repo-linked rate rises, most lenders quietly extend the tenure and leave the EMI alone. Nothing changes in your bank statement, which is exactly why the cost goes unnoticed until it has run for years.
The Rate Rise You Never See on Your Statement
Since October 2019 most floating rate retail loans in India have been linked to an external benchmark, usually the repo rate, and they reprice on a fixed cycle. When the benchmark rises, the lender has two ways to pass it on: raise the EMI and keep the tenure, or keep the EMI and extend the tenure. Most choose the second, because it requires no conversation with the borrower.
That choice makes the cost invisible. Your outgo is unchanged, your statement looks the same, and the loan has quietly acquired years of additional payments. On a loan with a long remaining term, a two point rise absorbed entirely through tenure can add many years, and on a loan already close to its natural limit the tenure cannot stretch far enough, at which point the EMI has to rise anyway.
The model below runs both versions so the trade is visible: the higher EMI you would pay to keep the tenure, and the longer tenure you accept to keep the EMI. It also computes the third option nobody is offered, which is the one-time prepayment that leaves both the EMI and the tenure exactly where they were.
Rate Rise Impact Model
Which Version of the Cost You Are Paying
The two lender responses cost different amounts and feel completely different. Raising the EMI keeps the loan on schedule and shows you the price immediately. Extending the tenure keeps your cash flow intact and generally costs more in total interest, because the balance stays outstanding for longer at a higher rate. Neither is a favour; they are two ways of collecting the same repricing.
The tenure route also has a hard limit that borrowers rarely know about. A loan cannot be extended indefinitely, both because lenders cap the term at your expected retirement age and because there is a mathematical ceiling: if the monthly interest on the outstanding balance reaches your EMI, no tenure repays the loan at all. Borrowers near that boundary get the EMI increase whether or not the lender prefers it.
The one-time prepayment that cancels the rise is the option almost nobody is offered, and it is often the most efficient. Paying down enough principal to restore the original schedule at the new rate leaves both the EMI and the end date untouched, and every rupee of it earns a guaranteed return equal to the new loan rate. On a floating rate loan to an individual there is generally no foreclosure charge on part prepayment, so the only cost is the alternative use of the money.
What Changes the Answer
The remaining tenure, more than the size of the loan
A rate rise on a loan with three years left is a minor irritation; the same rise with twenty-two years left is a large number, because the higher rate applies to a big balance for a long time. If you are early in the schedule, the response deserves proper thought rather than acceptance.
Your reset date
External benchmark linked loans reprice on a defined cycle, typically quarterly. The new rate does not apply from the day of the policy announcement but from your next reset, which means there is usually a short window in which a prepayment is made before the higher rate begins accruing.
The spread over the benchmark, which is negotiable and yours
Your rate is the benchmark plus a spread fixed at sanction. Lenders often quote lower spreads to new customers than the one you are carrying. Asking to be moved to the current spread, sometimes for a small conversion fee, can undo an entire rate rise without any refinancing.
Whether the loan should be refinanced instead
If another lender offers a materially lower rate, transferring the balance can be worth more than any prepayment. That decision needs its own arithmetic, because processing fees, legal and valuation charges all have to be recovered before the switch pays for itself.
