Fixed or Floating After the Repo Hike? The Break Even Math for a Bengaluru Home Loan

Two weeks after the RBI raised the repo rate, a Bengaluru buyer finalising a 75 lakh rupee home loan is offered a choice. The floating rate is 8.50 percent. A fixed rate for the full 20 years is 9.25 percent. The fixed EMI is about 3,600 rupees a month higher, and the salesperson says it buys peace of mind, because the RBI has signalled that rates will not fall soon. Is that peace of mind worth the price?

There is no way to know where rates will be in five years. But there is a way to know how far rates would have to rise for the fixed loan to come out cheaper. This guide does that arithmetic so that you can judge an offer on numbers rather than on fear.

The short answer. On an illustrative 75 lakh, 20 year loan, a fixed rate of 9.25 percent costs about 89.9 lakh rupees in interest, against about 81.2 lakh if a floating 8.50 percent rate never changes. The floating loan stays cheaper unless its rate rises by around 75 to 100 basis points early in the loan and stays there. The trade-off: a fixed rate buys certainty about the EMI, but at a premium you pay in every scenario except a sustained run of increases, so the decision depends on how much a higher EMI would hurt you.

Why is this question live after October 2026?

The RBI raised the repo rate by 25 basis points to 5.50 percent on 7 October 2026, according to the Monetary Policy Committee resolution. In the Governor's Statement, the RBI said that under its stance of calibrated tightening, rate cuts are off the table in the near term, and the path ahead can only be a rate hike or a pause, depending on growth and inflation data.

That language naturally makes fixed rates look attractive. But a pause is as possible as another hike, and over a 20 year loan, today's stance is only one chapter. The useful question is not whether rates will rise, but how much they would need to rise, and for how long, for a fixed rate to pay off.

How do fixed and floating compare across scenarios?

The table below compares a fixed 9.25 percent loan with a floating loan that starts at 8.50 percent, on 75 lakh rupees over 20 years. In each floating scenario, the EMI is recalculated at each rate change to keep the original end date. These are our illustrative calculations, not any lender's offer.

The fixed loan, at 9.25 percent, has an EMI of about 68,690 rupees and total interest of about 89.9 lakh rupees in every scenario. The pattern is clear. The floating loan stays cheaper even if its rate rises by 50 basis points and stays there for the rest of the loan. It roughly breaks even if rates climb by about 75 basis points over the next year and a half and never come down. Only a sustained rise of around 100 basis points, early in the loan, makes the fixed rate clearly cheaper.

The opposite case matters too. If the floating rate fell to 8.00 percent after two years and stayed there, total interest would drop to about 76.5 lakh rupees, about 13.4 lakh less than the fixed loan, and the EMI would fall to about 62,895 rupees.

What does the fixed premium buy you?

Certainty. With a fixed rate for the full tenure, your EMI does not depend on future RBI decisions, and you can plan the rest of your budget around a number that will not move. For a household whose budget is already stretched, or whose income is fixed, that certainty can be worth paying for, even if the arithmetic says floating is likely to cost less.

The question to ask yourself is practical: if your EMI rose from about 65,087 rupees to about 69,829 rupees, the 9.50 percent case in the table, could you pay it without strain? If yes, the floating loan's lower expected cost is probably the better bet. If no, the fixed rate is less about saving money and more about insurance, and insurance always has a premium.

Look closely at what "fixed" means in the offer. A fixed rate may apply only for an initial period, after which the loan converts to floating. A loan fixed for three years protects you through the near term but not beyond it, and you should compare it against floating on those terms, not as if it were fixed for 20 years.

What if the fixed offer is 9.00 percent instead? The size of the premium changes everything. A fixed rate of 9.00 percent on the same 75 lakh, 20 year loan has an EMI of about 67,479 rupees and total interest of about 87.0 lakh rupees. That is almost exactly what the floating loan costs if its rate rises to 9.00 percent after six months and stays there.

So at 9.00 percent, the break even point moves down to a sustained rise of about 50 basis points. If you think a rise of that size is likely to persist for most of the loan, a 9.00 percent fixed rate starts to look reasonable. At 9.25 percent, you need a bigger and longer lasting increase. Every quarter point of fixed premium matters, so negotiate it as hard as you would the floating spread. Ask each lender for its best fixed and floating quotes on the same day, so that you are comparing prices set under the same conditions.

Does your time horizon change the answer?

Yes, a great deal. Not every buyer keeps the same loan for 20 years; some prepay, refinance or sell. Over the first five years of our 75 lakh loan, the fixed 9.25 percent loan would cost about 33.0 lakh rupees in interest. The floating loan would cost about 30.1 lakh if its rate stayed at 8.50 percent, about 31.8 lakh if it rose to 9.00 percent after six months, and about 33.5 lakh if it rose to 9.50 percent.

In other words, over a five year horizon the fixed loan only comes out ahead if rates rise sharply and early. If you expect to prepay heavily or move within a few years, the case for paying a fixed premium is weaker still, and flexibility on prepayment matters more than the rate type.

What other terms should you compare?

The rate is only part of the comparison. Ask about processing fees and other charges, which can differ between the fixed and floating versions of the same loan. Ask how prepayments are treated on each, since flexibility to prepay matters a great deal over 20 years. And ask whether you can switch between fixed and floating later, at what cost and how many times.

Collect a Key Facts Statement for each option so that you are comparing the full cost on the same basis. Our guide to comparing home loan offers using the Key Facts Statement and APR explains how to read it.

Finally, compare fixed against a well priced floating loan, not against the first floating quote you received. If you can get a lower spread over the benchmark from another lender, the floating option becomes cheaper still, and the bar for the fixed rate rises.

How should a Bengaluru buyer decide?

If you are finalising a loan for a home in a project such as Abhee E-City in Electronic City, work through these steps before you sign:

1. Get written fixed and floating offers for the same amount and tenure.
2. Check whether the fixed rate applies for the full tenure or only an initial period.
3. Calculate the fixed EMI and the floating EMI at today's rate.
4. Test the floating EMI at 50 and 100 basis points higher and see if it still fits.
5. Compare total interest under a few rate scenarios, as in the table above.
6. Compare fees, prepayment terms and switching options on both versions.
7. Choose fixed only if the certainty is worth the premium to your budget.

We covered the wider choice between rate types in our earlier guide to fixed versus floating home loans in Bengaluru, which this update puts into numbers after the October increase.

What do borrowers ask most about fixed and floating rates?

Is a fixed rate home loan better after the October 2026 repo hike?

Not automatically. On an illustrative 75 lakh, 20 year loan, a fixed 9.25 percent costs about 89.9 lakh rupees in interest, while a floating loan at 8.50 percent stays cheaper unless its rate rises by around 75 to 100 basis points early and stays there. Fixed buys certainty at a premium.

How much would rates have to rise for a fixed loan to be cheaper?

In our illustration, with fixed at 9.25 percent and floating starting at 8.50 percent, the floating loan roughly breaks even if its rate climbs about 75 basis points over 18 months and stays there. A sustained 100 basis point rise early in the loan makes fixed about 2.4 lakh rupees cheaper.

What if rates fall instead?

Then the floating loan wins by a wide margin. In our illustration, if the floating rate fell to 8.00 percent after two years and stayed there, total interest would be about 76.5 lakh rupees, roughly 13.4 lakh less than a fixed 9.25 percent loan, with a lower EMI too.

Are fixed rate home loans fixed for the whole tenure?

Not necessarily. A fixed rate offer may apply only for an initial period, after which the loan moves to a floating rate. Read the offer carefully, ask how long the rate is fixed and what happens afterwards, and compare it with floating on those exact terms before you decide.
