Subvention schemes explained: 80:20, 20:80, and beyond

Subvention is one of the most misunderstood words in Indian real estate. Buyers hear "subvention" and think "the developer is giving me free money." Developers hear "subvention" and think "I am borrowing against future cash flow." Banks hear "subvention" and think "I have three parties on the deal, and I need all three of them to stay solvent." Each party is right about their own side; each is wrong about the others.

This guide walks through every major subvention structure used in India in 2026, the economic logic behind each, and when a given structure actually helps you as a buyer. It is written for the buyer weighing a scheme against a plain-vanilla construction-linked plan at a project like Forbes Fab Luxe Residences — Dec 2028 possession.

What subvention actually means

A subvention scheme is a three-party financing structure between the buyer, the bank and the developer. The bank disburses the loan; the buyer signs the loan documents; but the developer bears the EMI (or the interest component of it) during a pre-agreed period — usually the construction period. Once the period ends, the full EMI shifts to the buyer.

The developer "subsidises" the EMI during construction — hence the name. In exchange, the developer typically gets the full loan disbursed upfront as a single working-capital tranche, rather than in construction-milestone tranches. So it is a cash-flow arbitrage: the developer gets the cash earlier in exchange for carrying the EMI burden until possession.

The four most common structures, side by side

Variations and hybrids exist — the numbers shift depending on the developer's working capital need and the bank's risk appetite — but every subvention scheme is a version of one of these four patterns.

80:20 — the classic structure

Under 80:20, you pay 20% of the consideration from own funds at booking. The remaining 80% is sanctioned as a home loan, and typically disbursed in a large tranche to the developer shortly after booking. The developer pays the EMI (or interest portion) during the construction window; at possession, you take over. 80:20 was historically very common; RBI has flagged concerns about the structure and many banks have tightened norms. Some 80:20 variants are still offered; most have moved to 20:80 or 10:80:10.

Advantages for the buyer

• Low monthly outflow during construction — no pre-EMI burden
• Makes monthly cash flow smoother for buyers with large ongoing obligations (school fees, other EMIs, SIPs)
• Effectively lets you "time" the EMI start to possession

Risks for the buyer

• If developer defaults on subvention, EMI shifts to you immediately
• Large early disbursement is on your loan account — you owe the bank 80% of consideration from day one
• Interest is accruing on the full 80% from disbursement date — the developer is paying it, but it is still accumulating against your loan account
• Lower LTV or higher effective rate in some bank pricing

20:80 — the safer cousin

Under 20:80, you still pay 20% own funds at booking, but the 80% loan is not fully disbursed up front. It is disbursed in construction-linked tranches against builder demand notes. During construction, you pay "pre-EMI" — interest only on the disbursed portion. At possession, the loan is fully disbursed and full EMI begins.

20:80 is often described as a subvention, but strictly speaking it is a standard construction-linked plan with a marketing name. Pre-EMI is paid by the buyer, not subsidised — unless a developer specifically offers a pre-EMI waiver, in which case it becomes a genuine subvention. See our payment plans for under-construction property for the full spectrum.

10:80:10 — the current favourite

10:80:10 has become the dominant subvention variant in recent years. Pay 10% at booking from own funds. The bank sanctions 80%; disbursement is either milestone-linked or a single tranche depending on the specific scheme. The developer subsidises the EMI during construction — zero out-of-pocket during the build. At possession, pay the remaining 10% from own funds and begin the full EMI.

• Low out-of-pocket at booking (10%)
• Zero EMI during construction (if the scheme includes interest subvention)
• Moderate out-of-pocket at possession (10% + statutory charges + interiors)
• Full EMI kicks in post-possession

The 10:80:10 is cash-flow friendly for buyers who expect their income to grow over the construction window — a 30-year-old buying at Fab Luxe in 2026 will have higher income by December 2028 possession. The scheme effectively times the full EMI to when the buyer can most comfortably absorb it.

The real economics: who actually pays what

The developer's subsidy payment during construction is not free. It gets priced into the headline unit price — a subvention-scheme unit typically costs 2-5% more than the same unit on a plain construction-linked plan. The developer needs to recover the EMI they are carrying, and they do it through the sticker price.

Questions to ask before signing into a subvention

1. Is the scheme RBI-compliant? RBI has issued circulars tightening what banks can offer. Confirm the specific variant is permitted by your bank's credit policy in writing.
2. Who pays if developer misses a subvention payment? Get the specific answer from the sanction letter, not from the sales team.
3. Is the sticker price higher than the construction-linked variant? Ask for both prices side by side. The difference is what you are "paying" for the subvention.
4. What is the EMI amount from day-one-after-possession? Calculate it at the sanction rate plus 200 basis points as a stress test. This is the payment you will make for years.
5. Is there a pre-payment penalty during construction? Some subvention schemes limit early pre-payment; this removes a valuable option.
6. What is the disbursement timeline? Lump-sum disbursement to developer at booking (80:20) is riskier than milestone-linked.
7. How does the bank's tripartite agreement read? The tripartite agreement (buyer-bank-developer) is the document that governs who pays whom. Get a copy before you sign anything.

When subvention makes genuine sense

• Buyer has lumpy cash flow — annual bonus or business payout — that will land during the construction window
• Buyer is paying rent in another city currently and wants to avoid "double EMI" during construction
• Buyer is NRI and wants to minimise monthly INR outflow during the hold window — see our NRI buyer's guide
• Buyer expects income to step up meaningfully by possession and wants to time the full EMI to that higher income
• Buyer has higher-return use for capital during construction and wants to preserve it

When subvention is the wrong answer

• Buyer's primary concern is total cost — subvention adds 2-5% to the sticker
• Buyer's income is already steady — no cash-flow argument for deferring EMI
• Buyer wants to pre-pay aggressively — subvention often limits pre-payment flexibility
• Developer's balance sheet is not strong enough to carry subvention through a longer-than-expected build
• The scheme relies on a "guaranteed appreciation" or "assured rent" component — these are legally weak and have caused disputes in past projects

The tax angle you might miss

Under a subvention, pre-EMI interest is still interest — it is just being paid by the developer on your behalf. You cannot claim it as your own deduction during construction (the developer is not crediting it to you as income). At possession, the regular pre-construction interest aggregation rule applies — but only for interest you have actually paid. Interest paid by the developer on your behalf under subvention is outside this aggregation.

A clean three-step decision framework

1. Get two quotes: subvention price and construction-linked price for the same unit, same tower, same floor, same facing. The difference is your cost of the subvention.
2. Calculate the NPV: Discount the EMI stream under each plan at your opportunity cost of capital. The plan with the lower NPV is the cheaper one in economic terms.
3. Overlay your cash flow: Can you comfortably service the pre-EMI under the construction-linked plan, or will it crowd out other priorities? If yes, pick construction-linked. If no, the subvention premium is buying something valuable.
