Home Loan in India: EMI, Floating Rates, Prepayment and Tax Rules
A ₹50 lakh home loan at 8.5 percent over 20 years has an EMI of about ₹43,400. Over the full term you will pay roughly ₹54 lakh in interest. Now add ₹1 lakh of extra repayment every year. The loan ends in 14 years instead of 20, and the interest falls to about ₹35.6 lakh. Same loan, same bank, about ₹18 lakh saved. (Illustrative numbers. Your rate and EMI will differ.)
That gap is the whole story of home loans: the term is long, the interest is front-loaded, and small decisions early on are worth more than big ones later.
What the bank will actually lend
A home loan is a secured loan, and the property you buy stays mortgaged to the lender until the last EMI. The RBI limits how much of the property’s value a lender can finance. For individual housing loans the loan-to-value cap is 90 percent for loans up to ₹30 lakh, 80 percent for ₹30 to ₹75 lakh and 75 percent above ₹75 lakh. So on a ₹1 crore flat you need to fund at least 25 lakh yourself, and that is before stamp duty, registration and the processing fee, which are not part of the loan.
The other gate is your income. Lenders look at what share of your monthly income already goes to EMIs, and they will cap the new EMI so the total stays within what they consider safe. A good credit score gets you a lower rate rather than just an approval. If your score is under about 750, spend a few months fixing it before you apply, because a half-point rate difference over 20 years is a large sum.
| Illustrative ₹50 lakh loan | EMI | Total interest |
|---|---|---|
| 8.5% for 20 years | ₹43,391 | about ₹54.1 lakh |
| 9% for 20 years | ₹44,986 | about ₹58.0 lakh |
| 8.5% for 15 years | ₹49,237 | about ₹38.6 lakh |
Half a percentage point costs about ₹3.8 lakh over the term. Five fewer years costs about ₹5,800 more each month and saves about ₹15.5 lakh in interest.
Floating rates, and what happens when they move
Most home loans in India are floating. Since October 2019, a new floating-rate retail loan from a bank is linked to an external benchmark, most often the RBI’s repo rate. Your rate is that benchmark plus a spread the bank fixes, and it should reset when the benchmark changes, at least once every quarter. Older loans linked to MCLR or the earlier base rate are still around, and they tend to adjust more slowly. If you are on one, ask your lender about switching to the external benchmark. A switching fee may apply.
What a rate rise does to you depends on the choice made with your lender, and the RBI’s 2023 framework says the lender must give you the choice. You can take a higher EMI, a longer tenure, or a mix. Consider the same loan after five years of 8.5 percent, when about ₹44 lakh is still outstanding. If the rate jumps to 9.5 percent and you leave the EMI untouched, the loan runs about 27 months longer. Quietly, without a notice that feels dramatic, you have signed up for two extra years of payments. Lenders have to tell you when EMI or tenure changes, and they must offer you a switch to fixed, with any switching charges disclosed. Read those notices, because the extra months usually just show up in the statement.
Fixed-rate home loans exist but are usually priced higher and often convert to floating after an initial period. Check what happens at the reset.
Prepaying: the cheapest return you will ever get
On the loan above, roughly four-fifths of the first year’s EMIs are interest. Early on you are barely touching the principal. That is why extra payments in the first few years do the most damage to the total interest.
The RBI’s pre-payment directions bar lenders from charging a prepayment penalty on floating-rate loans to individuals for non-business purposes, partly or fully, whatever the source of the money. They apply to loans sanctioned or renewed on or after 1 January 2026, and many banks already followed this for floating home loans earlier. A fixed-rate loan can still carry a charge, so read the sanction letter.
When you prepay, tell the bank to reduce the tenure rather than the EMI, unless your monthly budget needs the relief. Cutting tenure saves the most interest. Do not drain your emergency fund to prepay either, because a home loan is the cheapest debt you will carry, and a job gap with no cash is far costlier.
Tax: check the numbers for the current year
The Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026, and the old section numbers you may remember no longer apply. As I understand it, the home loan benefits carried over in substance. Interest on a self-occupied home can be deducted up to ₹2 lakh a year, and principal repayment qualifies under the general investment deduction limit of ₹1.5 lakh, but only if you choose the old tax regime. Under the new regime you generally do not get the self-occupied deduction at all. I have not verified these against the Act itself, so check incometax.gov.in or ask your CA before you build a plan around the saving, and especially before choosing a regime.
If you buy jointly with a spouse who also earns, both of you can usually claim on your share of the repayments, subject to the same limits. Some states also give lower stamp duty when a woman is a co-owner, but that depends on the state.
What goes wrong
The rate gap for existing customers. Lenders often advertise a lower spread for new borrowers than they give to people already on their books. If your spread is well above what the same bank offers new customers, ask for a reduction, and compare a balance transfer, but weigh the fees on both sides.
Under-construction flats. You pay interest only on the amount disbursed, in stages. The builder’s payment schedule and the bank’s disbursement schedule do not always line up, so confirm the sequence before you sign.
Bundled insurance. Loan protection cover sold with the loan, often added to the loan amount, may or may not be worth it. Compare it with a plain term plan.
A weak title. The bank’s legal check protects the bank. It is not a guarantee for you, so have your own lawyer verify the title.
Key takeaways
- Early interest dominates. In the ₹50 lakh example, a ₹1 lakh extra payment each year cuts six years off the loan.
- The RBI caps loan-to-value at 90, 80 or 75 percent depending on the loan size, so budget for the down payment and the extra costs.
- On a floating rate, a rise in the rate can quietly add months to the loan. Read every reset notice.
- Floating-rate loans to individuals cannot carry prepayment penalties for loans sanctioned from 1 January 2026.
- Check current tax rules under the new Income-tax Act before counting on a deduction.
FAQ
How much home loan can I get? It depends on your income, existing EMIs, credit score and the property’s value. The RBI’s loan-to-value limit sets the ceiling on the property side, and the lender’s income checks set it on your side. Ask for a sanction in principle before you start house hunting.
Is a fixed or a floating rate better? Floating is far more common and usually cheaper at the start. It moves with the benchmark, so your EMI or tenure can change. A fixed rate gives certainty but is usually priced higher, so confirm whether it converts to floating later.
Can I prepay without a penalty? For floating-rate loans to individuals for non-business purposes, lenders cannot charge a prepayment penalty on loans sanctioned or renewed from 1 January 2026. Fixed-rate loans may differ, so check your sanction letter.
Should I move my loan to another lender? Only if the rate gap is meaningful and the saving over the remaining term beats the processing fee, legal charges and any switching costs. Ask your current bank to match the lower rate first, since that is often free.
