Three numbers decide everything: how much you borrow, the rate, and the tenure. Most people negotiate the first two and accept whatever tenure makes the EMI comfortable — which is the most expensive of the three decisions.
And one mechanic nobody explains: when interest rates rise, most banks quietly extend your tenure instead of raising your EMI. Your loan gets longer and nothing tells you.
This is the largest sum most people will ever borrow, repaid over a period longer than most marriages have lasted at the point of signing. It is worth understanding the machinery.
Where the money goes
An EMI is one fixed payment covering two very different things: interest on what you still owe, and repayment of the loan itself. Because interest is charged on the outstanding balance, and the balance starts at its largest, the early years are overwhelmingly interest.
On a ₹50,00,000 loan at 8.5 per cent over twenty years, the EMI is ₹43,391. In the first month, about ₹35,417 of that is interest and roughly ₹7,974 reduces the loan. It takes years before the split evens out.
This is not a bank being unfair. It is arithmetic. But it explains why selling in year four feels like you have paid a great deal and owe almost as much as you started with — because you have, and you do.
The tenure decision, which nobody treats as a decision
Ask for a lower EMI and you will be offered a longer tenure. It works, and here is what it costs.
| Tenure | EMI | Total repaid | Total interest |
|---|---|---|---|
| 15 years | ₹49,237 | ₹88,62,656 | ₹38,62,656 |
| 20 years | ₹43,391 | ₹1,04,13,879 | ₹54,13,879 |
| 25 years | ₹40,261 | ₹1,20,78,406 | ₹70,78,406 |
| 30 years | ₹38,446 | ₹1,38,40,443 | ₹88,40,443 |
Stretching from twenty years to thirty lowers the EMI by ₹4,945 a month — about ten per cent — and adds ₹34,26,564 in interest. You would pay more in interest than you borrowed.
Going the other way, shortening from twenty years to fifteen costs ₹5,846 more each month and saves ₹15,51,223.
The useful way to think about tenure is: take the shortest one whose EMI you can service comfortably in a bad year, not a good one. Comfortably means with the emergency fund intact and the investing continuing.
When rates rise, your loan gets longer
Most home loans in India are floating rate, linked to an external benchmark. When the benchmark moves up, the bank has two options: raise your EMI, or keep the EMI and extend the tenure. Most default to extending the tenure, because nothing changes in your bank account and nobody complains.
Here is what that does to a ₹50,00,000 loan taken for twenty years, with the EMI held at ₹43,391 throughout:
- At 8.5% — 20.1 years
- At 9.0% — 22.3 years
- At 9.5% — 25.8 years
- At 10.0% — 32.4 years
A one and a half per cent rise, absorbed silently, adds more than twelve years. Nothing in your statement announces this. Ask your bank for the revised tenure after every rate change, and if you can afford it, ask them to raise the EMI instead.
What decides your rate
Two borrowers at the same bank, on the same day, do not get the same rate. What moves it:
Your credit score. Most lenders now price risk explicitly — the best rate goes to the best scores. A single percentage point on this loan is worth around ₹7.7 lakh, which is covered in the credit score session.
Loan-to-value. Borrowing 90 per cent of the property price costs more than borrowing 70 per cent. A larger down payment buys a better rate as well as a smaller loan.
Your income and where it comes from. Salaried applicants at established employers are usually offered finer rates than self-employed applicants with identical incomes.
Whether you ask. Existing borrowers frequently sit on rates well above what the same bank offers new customers. Banks rarely volunteer a reduction.
The costs that are not the EMI
Budget for these separately, because none of them can be financed:
- Stamp duty and registration — commonly 5 to 7 per cent of the property value depending on the state, payable in cash.
- Processing fee — typically a fraction of a per cent, often negotiable, and frequently waived if you push.
- Legal and technical valuation charges for the bank's own checks.
- Insurance, which will be offered alongside the loan and presented as though it were part of it. A loan protection policy is not compulsory, and bundling it into the loan means paying interest on the premium for twenty years. If you want life cover, plain term insurance is usually cheaper and more flexible.
Two things worth knowing before you sign
You may prepay a floating rate home loan without penalty. Banks are not permitted to levy foreclosure or prepayment charges on floating rate loans taken by individual borrowers. This makes even small, irregular prepayments a genuine option — whether they are the best use of your money is the subject of the next session.
A joint loan with a co-applicant can improve eligibility, and where both are owners and both repay, each may claim the applicable tax benefits separately. Worth structuring correctly at the outset, because ownership is difficult to change afterwards.
The common mistake
Comparing loans on the EMI. The EMI is not the price of the loan — it is a payment schedule. A lower EMI usually means a longer tenure and a larger total cost. Compare total interest over the full tenure, which the sanction letter will not show you and a spreadsheet will.
The second mistake is treating the loan as settled once it is disbursed. Rates move, and the gap between what existing borrowers pay and what new borrowers are offered widens quietly. Reviewing your rate every couple of years — and asking for a reduction, or moving the loan — is one of the highest-value hours you will spend.
Jargon buster
- Principal
- The amount borrowed, as opposed to the interest charged on it.
- Amortisation schedule
- The table showing how each EMI splits between interest and principal across the whole loan. Ask for it.
- Floating rate
- A rate that moves with an external benchmark. Most Indian home loans are floating.
- Loan-to-value (LTV)
- The share of the property price you are borrowing. Lower LTV usually earns a better rate.
- Foreclosure
- Repaying the entire outstanding loan early.
- Balance transfer
- Moving your loan to another lender for a lower rate. Costs a fee, and is worth it when the rate gap is meaningful and the tenure remaining is long.
- Co-applicant
- Someone who applies jointly and is equally liable for repayment.
