Your Builder Pays ₹5 Per Sq Ft For Delay. You Pay 18% Interest
Usually that gap does not survive for RERA projects. Section 18 entitles you to interest for every month of delay at the prescribed rate, and Section 2(za) requires the interest a builder charges you on default to equal what it pays you.
Open almost any Indian builder-buyer agreement and compare two clauses: what you pay if an instalment is late, and what the builder pays if possession is late. The gap between them is the clearest single indicator of how the document was drafted. This guide shows how large that gap usually is in rupees, what the Real Estate (Regulation and Development) Act, 2016 says about it, how the Supreme Court has viewed one-sided agreements, and what to ask for before you sign or after the possession date has passed.
Key takeaways
- Builder-buyer agreements routinely charge the buyer 15 to 18 per cent interest on late instalments while offering a token per square foot amount for delayed possession.
- Section 2(za) of RERA requires the interest rate chargeable from the allottee on default to equal the rate the promoter pays on its default.
- Section 18 contemplates either withdrawal with a refund and interest, or interest for every month of delay if the allottee stays.
- The Supreme Court has held that buyers are not bound by wholly one-sided builder agreements.
- The possession date, grace period and force majeure clauses decide how much the statutory remedy is worth, so negotiate them before signing.
The two clauses to compare
Find the clause dealing with delayed payment by you. It will usually specify interest at a stated rate per annum on any overdue instalment, frequently in the region of fifteen to eighteen per cent, sometimes compounded, and often with a right to cancel the allotment after a set number of defaults.
Now find the clause dealing with delayed possession by the builder. It will often specify compensation at a fixed amount per square foot per month, such as ₹5 or ₹10, frequently calculated on super built-up area and payable only at the time of possession. On a typical flat this is a fraction of what you are paying in rent or EMI while you wait. The two are not comparable, and they were not drafted to be.
How big is the gap in rupees?
Take a flat in Noida priced at ₹90 lakh, sold as 1,250 sq ft super built-up. By the original possession date the buyer has paid ₹72 lakh, much of it through a home loan.
Under the agreement, delay compensation at ₹5 per sq ft per month comes to ₹6,250 a month. Over a two-year delay, that is ₹1.5 lakh.
Now run the buyer's side. If one instalment of ₹9 lakh is paid two months late at 18 per cent a year, the builder charges about ₹27,000 for those two months alone. Meanwhile the buyer is paying perhaps ₹25,000 a month in rent and ₹60,000 or more in EMI.
By contrast, if the prescribed rate under the State's RERA rules works out to roughly 11 per cent a year (the actual figure depends on the State rule and the benchmark rate at the time), interest on ₹72 lakh is about ₹66,000 a month, or close to ₹16 lakh over two years. That is the difference between the contractual figure and the statutory one, and it is why the clause matters.
What does Section 18 of RERA actually give you?
Section 18 of the Real Estate (Regulation and Development) Act, 2016 addresses the position where a promoter fails to complete or is unable to give possession of an apartment, plot or building in accordance with the terms of the agreement for sale, or by the date specified in it.
It contemplates two routes for the allottee. Where the allottee wishes to withdraw from the project, the section provides for return of the amount received with interest at the prescribed rate, and compensation. Where the allottee does not intend to withdraw, the proviso provides for interest for every month of delay until handing over of possession, at the prescribed rate. Which route suits a particular buyer is a commercial decision as much as a legal one.
The rate is set by State rules rather than by the agreement. Many States prescribe the State Bank of India's highest marginal cost of lending rate plus two per cent, but check the rule in your State, because the figure and the benchmark can differ.
Section 2(za): interest must run both ways
The definition of interest in Section 2(za) of the Act contains an explanation that speaks directly to the asymmetry. It says the rate of interest chargeable from the allottee by the promoter, in case of default, shall be equal to the rate of interest which the promoter shall be liable to pay the allottee, in case of default.
It also fixes the periods. Interest payable by the promoter runs from the date it received the money until the date the money and interest are refunded. Interest payable by the allottee runs from the date of default until payment.
In practical terms, an agreement for a RERA-registered project that charges you 18 per cent while paying you ₹5 per sq ft is out of step with the statute. When you raise it, cite Section 2(za) by number. It is a specific point, not a general complaint about fairness.
Note one consequence that cuts the other way. Equal interest also means the builder can charge you the prescribed rate on genuinely late instalments. Symmetry is not a way out of paying on time; it is a way of making sure the same rule applies to both sides when either of them is late, which is what most buyers actually want.
Clause by clause: what to look for
| Clause | Typical builder draft | RERA position | What to ask for |
|---|---|---|---|
| Interest on late instalments | 15 to 18 per cent a year, sometimes compounded | Section 2(za): same rate as the promoter pays on its default | The prescribed rate, applied equally to both sides |
| Delay compensation | ₹5 to ₹10 per sq ft per month, paid at possession | Section 18: interest for every month of delay at the prescribed rate | Monthly interest on amounts paid, at the same rate you pay |
| Possession date | Expected or tentative date | Section 18 is triggered by the date specified in the agreement | A fixed calendar date stated as a commitment |
| Grace period | Six to twelve months added before liability starts | Any grace period is contractual and is read against the Act | A short grace period, or none |
| Force majeure | Includes approvals, labour shortages, market conditions | Section 6 describes force majeure narrowly: war, flood, drought, fire, cyclone, earthquake or other natural calamity | A definition limited to events actually outside the promoter's control |
Why the contractual clause still matters
A buyer reading Section 18 might reasonably ask why the agreement clause matters at all. In practice it matters for two reasons. First, it is what the builder will point to in correspondence, and most disputes are resolved by correspondence rather than by adjudication. Second, the agreement is where the possession date itself is defined, and a statutory remedy for missing a date depends on the date being clear.
That is why the possession date clause deserves as much attention as the penalty clause. A date expressed as a target, or subject to extension for a long list of circumstances, weakens the position before any question of remedy arises. Section 18 applies to projects that fall under RERA; for an older project outside it, the contract and consumer law carry more of the weight.
The clauses that erode the date
- Possession described as anticipated, expected or targeted rather than committed.
- A grace period of six or twelve months added on top before any liability arises.
- Force majeure drafted so broadly that ordinary construction and approval delays fall inside it.
- Extension permitted for delays in obtaining approvals, which are the promoter's own responsibility to pursue.
- A requirement that the buyer be free of any default before claiming, which turns a single late instalment into a forfeiture of the remedy.
- A clause that the buyer's acceptance of possession waives all claims for delay, which you should strike or qualify.
What have courts said about one-sided builder agreements?
In Pioneer Urban Land and Infrastructure Ltd v Govindan Raghavan (2019), the Supreme Court considered an agreement where the buyer paid 18 per cent interest on delay while the builder paid ₹7 per sq ft per month. The Court held that a buyer cannot be bound by terms that are wholly one-sided, and that using such terms is an unfair trade practice under consumer protection law.
The Supreme Court has also held, in Imperia Structures Ltd v Anil Patni (2020), that the remedy under RERA does not bar a homebuyer from approaching a consumer commission. Which forum suits your case depends on the amount involved, the relief sought and how the local authority functions, which is a question for an advocate.
What to do
Before signing, ask for the possession date to be committed rather than indicative, for the grace period to be short or removed, and for the delay compensation to be expressed on the same basis as the interest you pay. Symmetry is a reasonable ask, it is backed by Section 2(za), and the response tells you a great deal.
Sample wording to propose: "If the Promoter fails to hand over possession by [date], the Promoter shall pay the Allottee interest at the rate prescribed under the applicable RERA rules for every month of delay on all amounts paid by the Allottee, which rate shall be the same rate payable by the Allottee on any delayed payment."
If you are already in a delayed project, write to the promoter citing the possession date, Section 18 and Section 2(za), and keep the reply. The position then depends on your agreement, the project's registration status and how the delay arose. Complaints under the Act are made to the State authority, and that is the point at which advice from an advocate who does RERA work is worth considerably more than a general article.
Whichever stage you are at, keep a ledger of every payment: date, amount, receipt number and bank reference. Delay interest is calculated on the amounts you have paid, and on a refund Section 2(za) runs interest from the date the promoter received each amount, so a clean ledger lets you calculate the claim yourself and check any figure the builder offers in settlement.

Review your builder-buyer agreement contractCommon questions
My agreement says the builder pays a fixed amount per square foot for delay. Is that all I can claim?
Not necessarily. The agreement records what the parties wrote, but for a RERA project Section 18 provides for interest at the prescribed rate for every month of delay, and Section 2(za) requires that rate to match what the builder charges you on default. How the two interact in your case depends on the facts and is worth taking to an advocate.
The builder says the delay was force majeure. Does that end it?
No. Force majeure clauses in builder agreements are often drafted very broadly, and whether a particular cause falls within one is a question of construction and evidence. RERA's own description of force majeure in Section 6 is narrow, covering events such as war, flood, fire or earthquake. A blanket assertion is not the same as establishing it, so ask for specifics in writing.
Should I withdraw or stay and claim interest?
That is a financial decision as much as a legal one, turning on the current value of the property, how far the project has progressed, the promoter's financial health and what you would do with a refund. Section 18 contemplates both routes. Model both in rupees, including rent and EMI you are paying, before choosing.
What is the interest rate for delayed possession under RERA?
It is the rate prescribed in your State's RERA rules. Many States set it at the State Bank of India's highest marginal cost of lending rate plus two per cent, which changes as that benchmark moves. Check the current rule for your State and the benchmark on the relevant dates, rather than relying on a figure quoted by the builder.
Can the builder charge me 18 per cent interest on late payments?
For a RERA project, the builder's charge is tied to the rate it must pay you on its own default under Section 2(za), which is the prescribed rate. An agreement charging 18 per cent while paying a token amount for delay is out of step with that. Raise it in writing before signing, and keep a copy.
Does accepting possession end my claim for delay interest?
Not automatically, but some agreements and possession letters include a waiver of claims. Read the possession letter carefully before signing it, strike or qualify any waiver, and record in writing that you are accepting possession without prejudice to your claim for delay interest. That simple step preserves a position that is otherwise easy to lose.
