One

The chart the bank gives you

When you apply for a home loan, the bank gives you a schedule: an EMI, a number of years, and a table showing every instalment until the loan is paid. It looks precise. It is precise — for one situation only.

Every figure on it assumes the interest rate you are quoted today stays the same for the whole life of the loan. On a floating-rate loan, that is the one thing that will not happen. The rate is tied to the RBI's repo rate, and over twenty years the repo rate will move many times, in both directions.

Your loan, as the bank will show it
Loan{{ amountTxt }} over {{ tenureTxt }}
Rate quoted today{{ rateTxt }}
EMI{{ emiTxt }}
Interest over the loan, if the rate never changes{{ stayInterest }}

Every number in that box rests on the last three words of its final row.

Nobody is hiding this. Since 2023, RBI rules require lenders to explain at sanction how a rate change would affect your EMI or tenure. But the explanation is usually a paragraph in a long document, and nobody works it through for your own loan. This book does.

Two

How your rate actually moves

Three things decide what you pay. Learn them once and the rest of this book follows easily.

The benchmark. For most loans taken after October 2019 this is the RBI's repo rate — the rate at which banks borrow from the central bank. It is public, it changes only when the Monetary Policy Committee decides, and every borrower in the country sees the same number.

The spread. This is your bank's margin on top of the benchmark, fixed for you at the moment you sign. It depends on your credit score, your income and how well you negotiated. Two neighbours with identical loans from the same bank can be on spreads a full half-point apart. Your rate is the benchmark plus your spread, and nothing else.

The reset. A change in the benchmark does not reach you the day it is announced. It reaches you on your own reset date, which falls on a cycle set at disbursal — at least every three months for repo-linked loans, typically once a year for MCLR ones. Between resets your rate is frozen, whichever way the benchmark has moved.

Worth writing down
Your rate = the benchmark today + your spread, applied at your next reset. You can negotiate the spread. You cannot influence the benchmark. Most people spend their energy on the wrong one.

This is why two people can take the same loan, from the same bank, six months apart, and end up in completely different positions. Not because one was cleverer, but because the benchmark was somewhere different when their resets landed.

Three

What a rate cycle does to a twenty-year loan

The clearest way to see it is to take the same loan — ₹50 lakh over twenty years — and borrow it at different points in the real rate history, with the EMI fixed on the day of signing, exactly as a bank does it.

Borrowed EMI Actual term Interest, actual vs promised
Aug 2008, near the topRs 53,83913.8 yrsRs 38L vs Rs 79L
Mar 2023, at the peakRs 45,47017.3 yrsRs 44L vs Rs 59L
Jun 2019, rates fallingRs 43,07518.3 yrsRs 45L vs Rs 53L
Jun 2021, at the floorRs 37,72227.4 yrsRs 74L vs Rs 41L
May 2009, near the bottomRs 39,97430+ yrsRs 96L vs Rs 46L

Loans before October 2019 were priced off MCLR or BPLR, so the 2008 and 2009 rows are illustrative, modelled on the repo rate at a 2.65% spread. From 2019 the mechanics are exact.

The cheapest EMI can be the most expensive loan. The loan that felt expensive to sign can turn out the cheapest to own.

The June 2021 borrower signed at the lowest rate in a generation. Every rise since then lengthened their loan, and because the EMI never changed, they never noticed. The March 2023 borrower signed at the peak, which felt like the worst time — and every cut since has shortened their loan.

None of this is a lesson about timing. Nobody knew in 2021 that rates were about to rise, or in 2023 that they were about to fall. A twenty-year loan lives through three or four cycles. The day you sign is one moment in a long story, and the useful question is not when to borrow but whether your loan can absorb the next rise.

Four

Could you cope?

Before you sign, run one test the bank will not run for you: what happens to your loan if rates rise after you borrow.

When rates rise on a floating loan, your EMI usually stays the same and the loan gets longer. There is a limit to that. Once the loan would stretch past what the lender allows, the EMI has to go up instead. So the question to ask yourself is whether you could pay the higher EMI if you had to.

If rates rise 2% after you borrow
EMI quoted today{{ emiTxt }}
EMI to finish on your original date at +2%{{ stressEmi }}
The difference each month{{ stressGap }}

On your income of {{ incomeTxt }} a month, that is {{ pctNow }} today and {{ pctStress }} after the rise. {{ fitLine }}

Why 2%? Because it has happened. Between May 2022 and February 2023 the repo rate rose by 2.5 percentage points in nine months. A rise of that size during a twenty-year loan is not a worst case; it is something most borrowers will see at least once.

If the higher figure would break your budget, that is worth knowing now, while the choice is still yours. A slightly smaller loan, a longer tenure, or a larger down payment each give you room. None of them is available after you sign.

End of the free chapters

Nine chapters to go.

The rest of the book covers the spread you negotiate, EBLR against MCLR, fixed against floating, reading the sanction letter, what gets sold alongside the loan, your prepayment reserve, your first reset after signing, and what changes if the flat is still being built.

Five

The spread: the one rate you negotiate

Your rate has two parts. One is the repo rate, which the RBI sets and nobody can negotiate. The other is the spread — the bank's margin on top — and that is fixed for you, for the whole life of the loan, on the day you sign.

The spread depends mostly on your credit score and on whether you ask. Two people buying in the same building, from the same bank, on the same day, can be on spreads half a percent apart for twenty years.

What a better spread is worth on your loan
0.25% lower spreadsaves about {{ spreadSave25 }}
0.50% lower spreadsaves about {{ spreadSave50 }}

Over the full loan, at today's rate. It is the largest single saving most buyers leave on the table.

How to ask. Check your credit score before you apply; above 750 gives you leverage. Get two written offers. Ask each bank, in writing, for its spread over the repo rate — not just the headline rate, which moves. Then ask the bank you prefer to match the better spread. Many will.

Six

EBLR or MCLR, and why it isn't a detail

These two words decide how fast a rate cut reaches you, and the difference is not small.

EBLR — also called RLLR at some banks — is tied directly to the RBI repo rate and must be reset at least once a quarter. When the RBI cuts, your rate falls within three months, whether or not you ask.

MCLR is calculated by your bank from its own cost of funds. There is no published formula you can check. It resets annually, and it falls more slowly than the repo rate does, because a bank has little reason to hurry. Roughly a third of floating-rate home loans in India are still on it, mostly because they were taken before 2019 and nobody suggested switching.

How much of the 2025 rate cut reached you
RBI repo EBLR loan MCLR loan
125 bps 50 bps 0 JAN 2025 SEP 2026
The RBI cut 125 basis points between February and December 2025. The EBLR loan had all of it within a quarter of each decision. The MCLR loan, resetting annually and priced off the bank's own cost of funds, was still short of it a year and a half later. Same bank, same borrower, different benchmark.

If you are already on MCLR, you can switch to EBLR later — but it is cheaper to start on the right one. Banks charge a conversion fee, usually a few thousand rupees, and they are not required to offer it unprompted. In a cutting cycle, a single year on the wrong benchmark costs considerably more than the fee. In a rising cycle the calculation reverses, which is exactly why nobody can give you a blanket answer.

Before you buy

Ask which benchmark the offer is on. A new floating-rate home loan from a bank should be linked to an external benchmark such as the repo rate (EBLR). Confirm that in writing, along with the spread and the date of the first reset. If the offer is on anything else, ask why, and ask what your effective rate would be on EBLR.

Both answers are things they already know. Getting them in writing costs you nothing and takes the decision out of the realm of opinion.

Seven

Fixed, floating, and the hybrid pitch

Almost every home loan in India is floating, and most borrowers never actively chose that. It is worth understanding what the alternatives are and why they are offered.

Floating. Your rate follows a benchmark. You carry the risk of rises and get the benefit of falls. It is the cheapest option at signing, because you are absorbing the uncertainty rather than the bank.

Fixed. Your rate is locked. The bank is now carrying the risk, and it charges for that — typically one to two per cent above the floating rate on offer. Read the terms closely: many Indian "fixed" home loans are fixed only for an initial period, after which they convert to floating. A genuinely fixed twenty-year home loan is rare here.

Hybrid. Fixed for two or three years, floating after. Marketed as the best of both. In practice you pay a premium for the fixed period and then inherit whatever the cycle is doing when it ends, which is precisely the risk you paid to avoid.

The question to ask
If a fixed rate is offered, ask exactly how many years it is fixed for, what it converts to afterwards, and what the conversion is benchmarked against. If the answer to the third question is vague, the rate is not as fixed as the brochure suggests.

There is also a real asymmetry worth knowing. Fixed-rate loans frequently carry prepayment penalties, while floating-rate loans to individuals should carry none at all. If closing early is part of your plan, a fixed rate can cost you twice — once in the premium, once in the penalty.

Eight

Your sanction letter: four lines that matter

Before you sign anything else, ask for the sanction letter and read it. It is the document that sets the terms of your loan, and four things in it govern everything that happens for the next two decades.

Look for Why it decides things
The benchmark name
"EBLR", "RLLR", or "MCLR"
Decides whether RBI cuts reach you in months or in years. Chapter six.
The spread or margin
"repo + 2.65%" or similar
Fixed for you, but resettable for a fee. If new borrowers get better today, this is the number to argue about.
The reset frequency
quarterly, annual, or a date
Tells you which months actually matter. Put them in your calendar today.
Prepayment terms
charges, limits, lock-in
On a floating-rate loan to an individual there should be no prepayment penalty at all. If there is, question it.

If the bank offers only a verbal summary, ask for the letter in writing before you sign. Do not accept a phone call or a brochure in its place — you want the document, because the document is what you will quote back at them later.

Nine

What they sell you alongside the loan

The loan is the product you asked for. At the point of signing, several others will be added, usually presented as requirements rather than choices.

Loan protection insurance. A policy that clears the loan if you die. The idea is sound — a family should not inherit an EMI. The execution is often poor: the premium is frequently added to the loan itself, meaning you pay interest on your insurance for twenty years. A plain term life policy for the same cover, bought separately and paid annually, is usually markedly cheaper.

Property insurance. Reasonable, and often genuinely required. But you are not obliged to buy your bank's policy. Ask what it costs, then price the same cover independently.

Processing and administrative fees. Negotiable more often than you would think, particularly if you have a competing sanction letter in hand.

The single most useful sentence you can say at signing is: which of these is legally required, and which is optional? Ask it out loud, and ask for the answer in the document. Regulators have been clear that bundling cannot be made a condition of the loan, but the practice persists because very few borrowers ask.

Anything financed into the loan is not a one-time cost. It is that cost plus twenty years of interest on it. A thirty-thousand-rupee premium added to the principal is not thirty thousand rupees.

Ten

The prepayment reserve

Chapter four gave you a number: how much more a month this loan would need if rates rose 2%. Here is the most useful thing you can do with it.

Set that difference aside every month from the start, in a savings or liquid account you control. Call it your prepayment reserve.

Your reserve
Set aside each month{{ reserveTxt }}
After a year, you would have{{ reserveYear }}

If rates rise, the reserve pays the part-payment that cancels the rise before it reaches your loan. LoanRepo can tell you the exact amount after each RBI decision; it is usually a fraction of a year's reserve.

If rates stay the same or fall, the reserve still works for you. Put it against the principal once a year and the loan finishes years early. Early prepayment does the most good, because every rupee removed in the first years cancels the most future interest.

Either way you are paying a little more than the bank asked for, by choice, and it turns the rate cycle from something that happens to you into something you've already planned for. Keep six months of expenses separate before any of it goes to the loan; money put into a home loan is hard to get back.

Eleven

After you sign: what happens at a reset

Your reset is the only date in the year when your loan can change. Everything else is noise. Here is what to do when one arrives.

Wait for the statement covering that month, then check two numbers and only two.

The effective rate. Did it move, and by how much? Compare it against the repo rate change that preceded it. If the repo fell by 0.25% and your rate fell by less, ask why.

The remaining tenure. This is the number that quietly absorbs everything. Write it down every time. A tenure that grows while your EMI stays flat is the mechanism from chapter three, happening to you, in that month.

If your statement does not show remaining tenure — many do not — ask for it. The bank's system knows it exactly. A request by email creates a written record, which matters if you later disagree.

The thing most people miss
When rates fall, banks usually shorten the tenure and leave the EMI alone — the mirror image of what they do when rates rise. That is fine, and often the better outcome. But you can ask for the reduction as a lower EMI instead if cash flow matters more to you right now. They will not offer. You have to ask.
Twelve

Buying a flat that isn't finished

Everything so far assumed the loan is paid out in one go and the full EMI starts the next month. On a flat that is still being built, that is not what happens.

The lender pays the builder in stages, as the building reaches agreed points. You pay interest only on the amount paid out so far, which is usually called the pre-EMI. The full EMI starts when the last payout is made or at possession. Which of the two applies, and how the rate is re-set in between, is written in your sanction letter, and lenders differ.

An example
A Rs 80 lakh loan over 20 years at 8.25%, paid out in twelve equal payouts, one every three months, over 36 months. In the first month you pay about Rs 4,583 in interest. In the last month, with the whole loan paid out, you pay Rs 55,000. Over the 36 months the interest-only payments total about Rs 10.7 lakh, and you still owe the whole Rs 80 lakh.

The same loan on a ready flat, over the same 36 months, would have taken about Rs 24.5 lakh in EMIs and left about Rs 74.6 lakh owed. Under construction you pay less each month at first, and you have repaid nothing.

The full EMI. If your 20 years count from possession, the EMI is about Rs 68,165. If they count from the first payout, only 17 years are left and the EMI is about Rs 73,057. Ask which one applies before you sign, because the difference is about Rs 4,900 a month.

If the rate moves. On a repo-linked loan the rate is re-set at least every quarter, and a rise applies to everything already paid out and to every later payout. If the rate rose by 0.25% a quarter for eight quarters, the same loan would cost about Rs 12.8 lakh in interest-only payments, the last month would be about Rs 68,300, and the EMI at the end would be about Rs 78,500. That is an illustration, not a forecast.

If possession is late. Once the whole loan has been paid out, every month of delay costs about Rs 55,000 in interest on this loan, on top of any rent you are paying.

How much a lender can give
RBI limits a housing loan to an individual by its size: up to 90% of the price for a loan up to Rs 30 lakh, up to 80% for a loan above that and up to Rs 75 lakh, and up to 75% for a loan above Rs 75 lakh. On a Rs 1 crore flat the most a lender can usually give is therefore about Rs 75 lakh, and the rest has to come from your own money. A lender may set a lower limit than RBI does.

Where the safeguards may stop. The RBI rules that make a lender tell you about a change in your EMI or tenure, and offer you a choice, were written for loans repaid by EMI. Do not assume they apply while you are paying interest only. Ask the lender in writing how they apply.

Questions to ask, and to have answered in writing

While only part of the loan has been paid out, how is my rate re-set, and on what date is the first reset?

Does my tenure count from the first payout or from possession, and what is my EMI under each?

Do the payouts to the builder follow construction stages that I can see in writing?

Can I prepay during construction, and what happens to my payments if possession is late?

Is my quoted rate based on today's repo rate, or on an earlier one?

None of the figures here include GST, stamp duty, registration, or the rent you may pay while you wait. Add those before you decide how much you can afford.

What this book cannot tell you

It cannot tell you where rates go next. Nobody can, and anyone who says otherwise is selling something.

It cannot tell you whether to buy now or wait, which home to buy, or which bank to use. Those depend on your income, your family, your job and your plans — none of which a book knows.

What it can do is make sure you sign knowing what the chart doesn't show: that the rate will move, what each direction does to your loan, and that you have a plan for either. After you sign, The Quiet Years picks up where this book stops.

About this book

Before LoanRepo, I spent close to a decade advising retail investors as a financial adviser. What brought this book into existence was not an idea. It was the same conversation, repeated for years.

A client would call, puzzled, because their loan balance was not falling the way they expected. They had done nothing wrong. They had paid every instalment on time. And they had no way of knowing that the rate cycle had quietly added years to the end of their loan, because nothing they received in the post had ever mentioned it.

Every time, the explanation took about fifteen minutes. Every time, the reaction was the same: nobody told me. And every time, the information had been sitting in public records the whole while, in a form nobody had bothered to assemble for the person it affected.

This book is the part of that conversation that should have happened before signing. The fifteen-minute explanation, written down, with the arithmetic worked out and the questions you should be asking listed in an order that gets answers.

It has no sponsor. LoanRepo earns nothing from your bank, nothing from any lender, and nothing different depending on what you decide to do. That independence is the only reason this book can say some of what it says.
