RERA's ₹11,000/sq ft Reality: What Thane's 2022 Order Means for Every Navi Mumbai Buyer's Refund

Imagine paying ₹85 lakh for a flat in Kharghar, waiting four years, and then being told possession is delayed indefinitely. You ask for a refund. The builder offers you your money back — with no interest. That's the reality many Navi Mumbai buyers face.

But a RERA order from neighbouring Thane has changed the game. In 2022, a Thane RERA bench ruled that a builder must refund a buyer with 10.65% interest, calculated as SBI's MCLR plus 2% Mumbai Mirror. This order is significant because it sets a clear, transparent benchmark for compensation in refund cases — one that buyers in Navi Mumbai can and should invoke.

Here's what every Navi Mumbai buyer needs to know about this ruling, how the interest formula actually works, and — crucially — why this benchmark might still not be enough.

The Thane RERA Order: A New Compensation Benchmark

The Thane order wasn't a one-off. It applied a formula that many RERA benches across Maharashtra now use: SBI's Marginal Cost of Lending Rate (MCLR) plus 2%. At the time of the order, SBI's MCLR was around 8.65%, so the total interest was 10.65%. The builder was ordered to refund the entire amount paid, along with this interest, for the delay in possession.

Why is this important for Navi Mumbai buyers? Because Navi Mumbai projects — from Panvel to Ulwe to Kharghar — are under the same Maharashtra RERA jurisdiction. While rulings are not binding precedents in the strict legal sense, they carry persuasive weight. When you file a complaint against a Navi Mumbai builder, you can point to the Thane order and demand the same treatment.

How Interest Rates on Refunds Are Actually Calculated

The formula is straightforward: Refund amount + Interest at (SBI MCLR + 2%) from the date of payment until the refund is made.

Let's break that down:

• SBI MCLR: This is the marginal cost of funds-based lending rate, which SBI revises periodically. As of early 2025, it hovers around 8.65% for many tenors. You can check the current rate on SBI's website.
• +2%: This is the compensation for the builder's default. It's meant to account for the opportunity cost of your money.

So, if you paid ₹50 lakh to a builder in Ulwe and the project is delayed by three years, at 10.65% interest, you'd be owed roughly ₹16 lakh in interest alone, on top of your principal. That's a real number — and it's far better than what most builders initially offer.

But here's the catch: The formula is not automatic. You have to ask for it. RERA doesn't proactively calculate interest; you must plead for it in your complaint. And the builder will almost certainly offer a lower settlement first.

Why This Formula Doesn't Always Cover Your Actual Loss

Let's be honest: 10.65% interest might sound good, but it rarely covers what you actually lost. Here's why.

Inflation eats into it. Real estate prices in Navi Mumbai have risen roughly 8-10% per annum in many micro-markets. If your Kharghar flat was worth ₹80 lakh when you booked it in 2021 and is now worth ₹1.1 crore, getting back ₹80 lakh plus 10.65% interest (total around ₹1.05 crore) still leaves you short of what you'd need to buy an equivalent flat today.

Alternate rent is a real cost. If you've been paying rent while waiting for your flat, that's a direct financial loss. But RERA's formula doesn't automatically include it. You must explicitly claim it as 'compensation' under Section 18 of RERA.

Opportunity cost is higher than MCLR. If you'd invested that money elsewhere — say, in mutual funds or even a fixed deposit — you might have earned 7-8% in a relatively safe instrument. But the builder had your money, and the inflation-adjusted loss is often higher than 10.65%.

So, while the Thane order is a victory, it's a partial one. The formula is a floor, not a ceiling.

How to Argue for Higher Compensation in Navi Mumbai RERA

You don't have to accept just the SBI MCLR + 2% formula. RERA allows you to claim 'compensation' for actual losses under Section 18 of the RERA Act. Here's how to strengthen your case:

1. Document alternate rent: Keep rent receipts, leave and licence agreements, and bank statements showing rent payments. This proves a direct financial loss.
2. Show price appreciation: Use government-registered sale deeds from your project or nearby projects to show that the price per sq ft has gone up since you booked. This helps demonstrate that a simple refund doesn't make you whole.
3. Calculate your opportunity cost: If you took a home loan, the interest you paid on that loan (minus the 10.65% refund interest) is a loss. If you used your own funds, show what that money could have earned in a conservative fixed deposit.
4. Cite the Thane order: In your complaint, refer to the Thane RERA order as a benchmark. More importantly, argue that 'actual loss' under Section 18 goes beyond the formula — and ask the authority to apply its discretion.

In practice, many Navi Mumbai RERA complaints that ask for explicit 'compensation for rent' and 'escalation of project cost' have been awarded more than just the MCLR + 2% formula. The key is to ask.

What to Do If Your Builder Offers a Settlement Below the RERA Rate

Builders are smart. They'll often offer a settlement quickly — sometimes within days of you filing a complaint — but at a rate far below what the Thane order mandates. A common offer is 'refund of money with 6% interest' or even 'refund without interest, but quickly.'

Here's the trap: If you accept that offer, you're done. You can't go back and demand more later. So before you sign anything:

• Compare the offer with the Thane benchmark. Calculate what you'd get under the SBI MCLR + 2% formula (check the current SBI MCLR online). If the builder's offer is lower, that's a red flag.
• Ask for a written calculation. Request the builder to show how they arrived at their interest figure. If they can't, it's arbitrary.
• Don't rush. Builders count on your desperation. But a settlement below the RERA benchmark is rarely in your interest. You can always reject it and push for a hearing.
• Negotiate for 'actual loss' too. Even if you settle, you can negotiate for rent compensation or a waiver of your legal costs. Don't settle for the bare minimum.

If the builder refuses to match the RERA benchmark, let the case proceed. The Thane order is on your side — and MahaRERA has been consistently applying this formula in recent orders.

What This Means for Your Navi Mumbai Purchase

The Thane order is a wake-up call for builders across the MMR, including those in Kharghar, Panvel, Ulwe, and Nerul. It signals that RERA benches are willing to impose meaningful interest on delayed refunds.

For buyers, the lesson is twofold:

1. Always read your builder-buyer agreement for refund clauses. Many agreements mention interest at 8-9% or even 'as per RERA.' The RERA rate is higher — make sure you know what you're entitled to.
2. Keep records. Every payment receipt, booking form, and email matters. If you need to file a complaint, you'll need to prove the date of payment.

And if you're already in a dispute, don't settle for less. The legal framework is on your side — but only if you ask.

Bottom Line

The ₹11,000/sq ft figure in the title? It's not a per-square-foot refund. It's a reminder that the interest on your refund is calculated per square foot, per year — and it adds up. At 10.65% on a ₹1 crore payment over three years, that's ₹3.2 lakh in interest. It's real money.

So next time a builder offers a 'quick settlement,' ask yourself: Is this more than what RERA's own formula gives me? If not, you're being short-changed.

File your complaint, cite the Thane order, and demand your due. Navi Mumbai buyers deserve no less.
