Down Payment for a Home Loan in India: How Much in 2026

"The bank approved 90%, so why do I need so much cash?"

You apply for a home loan on a ₹40 lakh flat, and the bank's sanction letter says it will finance up to 90% of the property value. You do the mental math — 10% of ₹40 lakh is ₹4 lakh, comfortably within your savings — and start planning the move. Then the demand for funds arrives, and it's nowhere near ₹4 lakh. It's closer to ₹7-8 lakh, and you're left wondering what went wrong.

Nothing went wrong — you simply ran into the gap between "down payment" (what the bank calculates its loan-to-value against) and "cash you actually need at closing" (down payment plus stamp duty, registration, GST if applicable, and a buffer). This is one of the most common budgeting shocks for first-time buyers in India, and it happens because the Reserve Bank of India's loan-to-value (LTV) rules set a floor on your deposit percentage — but the property value the bank lends against is not the same as the total cash outlay you'll need.

This article walks through exactly how RBI's LTV bands work by loan size, what "margin money" really means, how much cash you need on a ₹30 lakh, ₹60 lakh and ₹1 crore flat, and how to build your real number before you fall in love with a flat you can't actually close on.

What "down payment" really means vs margin money vs LTV

Three terms get used almost interchangeably by builders and loan agents, but they mean distinct things:

• LTV (loan-to-value) ratio is the percentage of the property's assessed value that a bank is permitted to lend, as capped by RBI guidelines. It is a regulatory ceiling on the lender, not a target for the borrower.
• Margin money is the portion of the property value that you must fund yourself, precisely because the LTV cap prevents the bank from financing 100%. If LTV is capped at 80%, your margin money is at least 20% of that valuation.
• Down payment is the informal, buyer-facing term for margin money — but in everyday use, buyers often conflate it with "all the cash I need," which is where the confusion starts, because margin money is calculated on property value, not on the full transaction cost including stamp duty, registration and GST.

The critical nuance: the bank's LTV percentage applies to the property value (typically the lower of the agreement value or the bank's own valuation) — it does not include stamp duty, registration charges or GST, none of which any lender will finance. So even a buyer who qualifies for the maximum 90% LTV band ends up needing meaningfully more than 10% in cash once these compulsory, non-financeable costs are added.

The 10-25% rule, and why RBI's LTV caps set the floor

RBI's loan-to-value guidelines for housing loans are structured in bands tied to the loan amount, and are widely published across lenders as the industry-standard caps (always confirm the current band and any lender-specific tightening with your bank, since individual lenders may apply stricter internal limits than the regulatory ceiling):

• Loans up to ₹30 lakh: LTV can go up to around 90%, meaning your minimum margin money is roughly 10%.
• Loans between ₹30 lakh and ₹75 lakh: LTV caps at around 80%, meaning your minimum margin money is roughly 20%.
• Loans above ₹75 lakh: LTV caps at around 75%, meaning your minimum margin money is roughly 25%.

This is why you'll hear the popular shorthand "10-25% down payment rule" — it isn't an arbitrary range, it directly mirrors these RBI LTV bands. Importantly, these are caps on the lender, not a promise to the borrower — many banks apply their own tighter internal margin requirements based on your credit profile, income stability, or the specific property, so your actual minimum could be higher than the regulatory floor.

Data table: LTV band, deposit %, and rupee deposit by loan size

The table below applies the standard LTV bands to three illustrative flat prices, assuming the loan amount equals the property value (i.e., the flat price and the loan-eligible value are the same, which won't always hold once stamp duty and GST are excluded from the base).

Notice how the required deposit percentage rises with loan size — the RBI bands are designed to reduce leverage risk as ticket sizes increase, but the practical effect for a buyer stepping from a ₹60 lakh flat to a ₹1 crore flat is that the deposit doesn't just scale proportionally, it scales up in percentage too. A buyer moving into the premium segment should budget for a materially larger margin than they might assume from a mid-market purchase.

Why a "10% down payment" is really more like 18-22% in cash

Here's the part that trips up most first-time buyers: the bank's LTV percentage is calculated on the property value, excluding stamp duty, registration and GST — but none of those costs are financeable by the home loan. You have to pay them entirely out of pocket, on top of your margin money. So even in the best-case 90% LTV band:

• Margin money: ~10% of property value
• Plus stamp duty: typically 5-7% of the property value, varying significantly by state (always confirm the current rate with your state's stamp duty schedule, since some states offer rebates for women co-owners or joint ownership)
• Plus registration: typically around 1% of the property value in most states
• Plus GST (if under-construction, 1% for affordable housing or 5% otherwise; nil for ready-to-move with an occupancy certificate)
• Plus a realistic buffer for moving, initial society charges, and unplanned costs

Add those together and a "10% down payment" flat can realistically require 18-22%+ of the property value in upfront cash — before you've spent a rupee on furnishing. This is exactly the gap that catches buyers off guard when the sanction letter says "90% LTV" and they assume that means "10% cash needed."

Geographic and demographic specifics: stamp duty, GST, and city affordability

State stamp duty rates vary meaningfully — some states charge closer to 5%, others closer to 7%, and several offer a rebate (often 1-2 percentage points) for properties registered solely or jointly in a woman's name. Registration charges are typically around 1% nationally, though exact caps differ by state. Because these are state-subject charges, always verify the current rate for your specific state and municipality before finalizing your budget — a stamp duty calculator is the fastest way to do this reliably.

GST treatment also depends on construction status: an under-construction flat attracts GST (1% for qualifying affordable housing, 5% for other residential categories), while a ready-to-move flat with a valid occupancy certificate attracts no GST at all. This single factor can be a multi-lakh swing in your total cash-needed figure, so confirm the OC status before you assume either GST rate applies.

On top of these transactional costs, it's worth sanity-checking your target loan size against your income using a broad affordability signal. Knight Frank's Affordability Index for H1 2024 found EMI-to-income ratios varying sharply by city — around 51% in Mumbai versus roughly 24% in Pune and Kolkata and about 21% in Ahmedabad — reflecting how much more stretched a Mumbai buyer's monthly budget typically is relative to income compared to several other metros (Knight Frank Affordability Index, Aug 2024, via Outlook Money). If your city sits at the higher end of that range, it's a signal to be more conservative about loan size and lean toward a larger down payment rather than the regulatory minimum, to keep your EMI-to-income ratio manageable.

Mini scenario: a Pune buyer totals the real cash needed on a ₹55 lakh flat

Meera is a first-time buyer in Pune eyeing a ready-to-move flat priced at ₹55 lakh. Because the loan falls in the ₹30-75 lakh band, her bank caps LTV at 80%, so her minimum margin money is ₹11 lakh (20% of ₹55 lakh). She initially budgets exactly ₹11 lakh in savings and assumes she's done.

When she runs the full numbers, though, she finds Maharashtra's stamp duty (illustrative, always confirm current state rate) plus 1% registration add roughly ₹3.85 lakh more on a ₹55 lakh transaction. Because the flat is ready-to-move with an OC, she owes no GST — a relief she wouldn't have had if she'd chosen an under-construction unit instead. Adding a modest ₹1.5 lakh buffer for moving costs and initial society charges, Meera's real cash-needed figure comes to roughly ₹16.35 lakh — about 30% more than the ₹11 lakh she originally budgeted, purely because she was thinking in "margin money" terms instead of "total cash to close" terms.

This is a hypothetical, illustrative scenario to show the calculation method — actual stamp duty, registration and any applicable rebates should always be confirmed against current state rules before you finalize a budget.

Deposit vs. the full cash you actually need

Pro tips

1. Ask your lender for the exact LTV percentage they'll apply to your profile and this property — don't assume the regulatory ceiling is what you'll get.
2. Model your total cash-to-close, not just the margin money, before you shortlist a price range.
3. If your city shows a high EMI-to-income ratio in affordability data, lean toward a larger voluntary down payment to keep your monthly EMI comfortable, not just compliant with the LTV floor.
4. Confirm whether the property is under-construction or ready-to-move early — the GST difference alone can change your cash-needed figure by lakhs.
5. Keep your margin money and stamp-duty funds in a account you can show as verifiable savings well ahead of loan application — lenders scrutinize the source of your own contribution.

Common mistakes to avoid

• Assuming the LTV percentage the bank quotes covers your entire cash requirement.
• Forgetting stamp duty and registration are non-financeable and calculated on top of the margin money.
• Not checking whether GST applies before comparing an under-construction flat's total cost to a ready-to-move one.
• Waiting until loan application to start saving margin money, instead of building it visibly over months.
• Ignoring city-level affordability signals and stretching into an EMI that consumes an outsized share of monthly income.

Once you know your target down payment, model the resulting loan amount, tenure and EMI on the EMI calculator — it's the fastest way to see how increasing your deposit reduces your monthly outgo. For the full financial picture — margin money, stamp duty, registration, GST and a buffer, all in one place — buyer financial planning helps you assemble a single, complete number instead of tracking scattered estimates across notes and spreadsheets. And before you commit to a price range at all, start your free requirements brief to anchor your search to a budget your savings can realistically support, rather than working backward from a flat you've already fallen for.

The value of getting this right before you shop

A gap between "down payment" and "cash needed" discovered after you've already made an offer can mean a scramble for a top-up loan, a delayed registration, or worse, losing a booking amount because you couldn't close in time. Running the numbers upfront costs nothing and takes a few minutes.

Key takeaways

• RBI's LTV bands set a floor on your margin money: roughly 10% up to ₹30 lakh loans, 20% for ₹30-75 lakh, and 25% above ₹75 lakh — always confirm the current band and any lender-specific tightening with your bank.
• LTV is calculated on property value only — it excludes stamp duty, registration and GST, none of which the loan finances.
• A "10% down payment" flat can realistically need 18-22%+ of the property value in total cash once stamp duty, registration and any GST are added.
• Stamp duty (roughly 5-7%) and registration (roughly 1%) are state-specific — always confirm current rates before budgeting.
• GST applies only to under-construction property (1% affordable / 5% other); ready-to-move flats with an occupancy certificate attract no GST.
• City-level EMI-to-income data (e.g., Mumbai far higher than Pune, Kolkata or Ahmedabad per Knight Frank's H1 2024 index) is a useful sanity check on how much loan to actually take, beyond the LTV minimum.
• Model your total cash-to-close, not just margin money, before shortlisting a price range.
• This article is educational information, not financial advice — confirm your specific LTV, stamp duty and GST obligations with your lender, state authority, and a licensed professional.

FAQ

Is the RBI LTV percentage the same at every bank? The LTV bands are regulatory ceilings; individual banks may apply stricter internal margin requirements based on your credit score, income stability, or the specific property. Always confirm your actual sanctioned LTV with your lender.

Does a higher down payment always mean a lower interest rate? Not necessarily an automatic discount, but a lower loan amount relative to property value can improve your risk profile with the lender and may support better negotiating terms — this varies by lender and is not guaranteed.

Can I use a personal loan to cover the shortfall in margin money? Most lenders require margin money to come from your own genuine savings, not borrowed funds, and may ask for a source-of-funds trail. Confirm your specific lender's policy before assuming this route is available.
