Already Paying an EMI? What a 25 bps Rise Does Five and Ten Years Into a Bengaluru Home Loan

Rs 741 a month. That is roughly what a 25 basis point rate rise would add to the EMI on a Rs 80 lakh Bengaluru home loan that is already ten years into a 20-year term, in our worked example. The same rise would add about Rs 1,261 a month to a brand-new loan of the same size. The difference comes from one number most borrowers never look at closely: the outstanding balance.

The RBI website lists the policy repo rate at 5.50 per cent, after the Monetary Policy Committee voted unanimously on 7 October 2026 to raise it by 25 basis points, according to the Governor's statement. Most coverage of a rate change looks at new borrowers. This guide looks at people already repaying. It does not predict rates or describe any lender's terms.

The short answer. In our example, a Rs 80 lakh, 20-year loan at an illustrative 8.25 per cent has an EMI of about Rs 68,165. If the rate rises to 8.50 per cent and the lender raises the EMI, the increase is about Rs 1,261 at the start, Rs 1,026 five years in and Rs 741 ten years in. If the lender keeps the EMI and extends the tenure instead, the loan runs about 12, 6 and 2 months longer respectively. The trade-off: keeping the EMI feels easier each month, but it adds roughly twice as much extra interest as paying the higher EMI, five years into the loan.

Why does the same rate rise hurt less later in a loan?

Because interest is charged on what you still owe. On a reducing-balance home loan, each month's interest is calculated on the outstanding principal. Early on, that balance is close to the original loan. Later, after years of repayment, it is smaller, so the same change in rate produces a smaller change in interest.

In our example, using the standard reducing-balance formula with monthly compounding and assuming the rate stays constant after the change, the outstanding balance on the Rs 80 lakh loan is about Rs 70.26 lakh after five years and about Rs 55.58 lakh after ten years. Those are the amounts the new rate applies to.

The rates used here, 8.25 and 8.50 per cent, are illustrative and are not any lender's quoted rate. Your own loan's rate, spread and reset dates are in your loan documents.

What does the rise do at each stage of the loan?

The table sets out the two routes a lender might take after a rate change: raise the EMI to keep the end date, or keep the EMI and extend the tenure.

The pattern is consistent. The further into the loan, the smaller the monthly increase and the fewer extra months the tenure route adds. But at every stage, keeping the EMI and stretching the tenure costs more in total interest than paying the higher EMI.

Why does extending the tenure cost more?

Because the extra interest compounds over the added months. When the EMI stays the same and the rate rises, a little more of each payment goes to interest and a little less to principal. The balance falls more slowly, so interest is charged on a higher balance for longer, and the loan needs extra months to finish.

In our example, five years into the loan, the higher-EMI route adds about Rs 1.85 lakh of interest over the remaining 15 years. The longer-tenure route adds about Rs 3.80 lakh, roughly double. At the start of the loan the gap is wider: about Rs 3.03 lakh against Rs 8.28 lakh.

That is not an argument that every borrower should choose the higher EMI. If the monthly budget is tight, keeping the EMI may be the right call. It is an argument for knowing which route your lender has applied and what it costs. PropNewz explained the choice between EMI and tenure changes in more detail in our guide to floating-rate resets and the EMI or tenure choice.

What can an existing borrower do after a rate rise?

Start by finding out what has actually changed. Your loan statement is the place to look for the rate applied, the EMI and the remaining tenure. Our guide to reading a quarterly home loan statement explains where to find each figure.

Then compare the figures with the arithmetic. If the EMI has not changed but the rate has, the tenure has probably been extended. Ask the lender for the new end date and the revised total interest. If the EMI has gone up, check that the increase is in line with the rate change on your outstanding balance.

A borrower with spare cash can also consider a part-prepayment, which reduces the balance the higher rate applies to. Whether that makes sense depends on your other needs, such as an emergency fund, and on your loan terms, so check them before you pay.

What would a part-prepayment do five years in?

Reduce both the balance and the time left. Take the same Rs 80 lakh loan five years in, after the rate has risen to 8.50 per cent and the EMI has gone up to about Rs 69,191. If the borrower prepays Rs 5 lakh, the outstanding balance falls from about Rs 70.26 lakh to about Rs 65.26 lakh.

If the EMI stays at about Rs 69,191, our arithmetic shows the remaining term falling from 180 months to about 156 months, two years earlier than planned. Interest over the rest of the loan falls from about Rs 54.28 lakh to about Rs 42.86 lakh, a saving of roughly Rs 11.42 lakh for the Rs 5 lakh paid.

Alternatively, if the lender recalculates the EMI over the original 180 remaining months, the payment would drop to about Rs 64,267, which is lower than the EMI before the rate rise. That route eases the monthly budget but saves less interest than keeping the EMI and finishing early.

These are illustrative figures. Before prepaying, check your loan terms for any conditions, and keep enough cash aside for emergencies.

Does the stage of the loan change the decision?

It changes the stakes. Early in a loan, the choice between a higher EMI and a longer tenure is worth several lakh rupees of interest in our example. Ten years in, the difference shrinks to about half a lakh. A borrower near the end of a loan may reasonably decide the extra few months are not worth worrying about, while a borrower in the first few years has more reason to look closely.

It also changes how much a prepayment is worth. Money paid early in a loan removes principal that would otherwise attract interest for many more years, so the same rupee of prepayment saves more interest at year two than at year twelve.

The same logic applies if rates fall. A cut would reduce interest by more early in the loan than late, and the choice between a lower EMI and a shorter tenure would carry the same kind of trade-off in reverse.

How should an existing Bengaluru borrower respond?

With a short, written review of the loan, rather than waiting for the next statement.

1. Find your current outstanding balance, rate, EMI and remaining months on your latest loan statement.
2. Check your sanction letter or Key Facts Statement for the benchmark, spread and reset frequency.
3. Work out what a 25 basis point change does to your EMI on the outstanding balance, using the remaining months.
4. Ask the lender in writing whether it has raised your EMI or extended your tenure, and request the new end date.
5. Compare the extra interest under each route for your own balance and remaining term.
6. If you prefer the other route, ask the lender whether you can switch and what it requires.
7. Keep a simple record of each reset, with the rate, EMI and tenure before and after.

Frequently asked questions

How much does a 25 bps rise add to an existing Rs 80 lakh EMI?

In our worked example of a 20-year loan at an illustrative 8.25 per cent, a rise to 8.50 per cent adds about Rs 1,261 a month at the start, about Rs 1,026 five years in and about Rs 741 ten years in, because the outstanding balance is smaller later in the loan.

Is it cheaper to raise the EMI or extend the tenure after a rate rise?

In our example, raising the EMI costs less in total interest. Five years into a Rs 80 lakh loan, the higher-EMI route adds about Rs 1.85 lakh of interest over the remaining term, while keeping the EMI and extending the tenure adds about Rs 3.80 lakh.

What is the repo rate now?

The RBI website lists the policy repo rate at 5.50 per cent. The Governor's statement of 7 October 2026 says the Monetary Policy Committee voted unanimously to raise it by 25 basis points, with the standing deposit facility at 5.25 per cent and the marginal standing facility at 5.75 per cent.

How will I know if my lender has changed my rate?

Check your loan statement and any reset communication from the lender, and compare the rate, EMI and remaining tenure with your sanction letter or Key Facts Statement. If the change is unclear, ask the lender in writing to show the old and new figures side by side.
