Your Builder Owes You Rs 10.85 Lakh on a Rs 50 Lakh Flat Delayed by 2 Years
RERA compensation is calculated at SBI MCLR + 2% simple interest on the total amount you have paid. As of April 2026, SBI’s 1-year MCLR stands at 8.85%. That makes the effective RERA interest rate 10.85% per annum.
On Rs 50 lakh paid to the builder, a 2-year delay means:
Rs 50,00,000 x 10.85% x 2 = Rs 10,85,000
That is Rs 10.85 lakh the builder owes you — by law, not by goodwill. Most buyers never claim it. Of those who do, most do not know the exact amount they are entitled to. This guide fixes both problems.
If you have not yet verified whether your project is even RERA-registered, start with how to verify RERA registration before anything else. And if you are unsure whether RERA is the right forum for your complaint, read RERA vs Consumer Court vs NCLT — which forum to choose.
The RERA Compensation Formula
Section 18 of the Real Estate (Regulation and Development) Act, 2016 mandates that if a builder fails to deliver possession by the agreed date, the buyer is entitled to interest on every rupee paid.
Formula:
Compensation = Total Amount Paid x (SBI MCLR + 2%) x Number of Years Delayed
Key details:
- Interest type: Simple interest in most states (not compound)
- Base rate: SBI’s 1-year Marginal Cost of Funds Based Lending Rate (MCLR)
- Markup: 2% above MCLR (standardized across most states)
- Calculation period: From the promised possession date in the registered agreement to the actual possession date or date of refund
- Applied on: Total amount paid by the buyer, not the agreement value
The interest is calculated on each installment from the date it was paid, not from a single lump-sum date. If you paid Rs 20 lakh in 2021 and Rs 30 lakh in 2022, the interest on the first Rs 20 lakh runs longer.
State-Wise RERA Interest Rates (April 2026)
All major states have converged on SBI MCLR + 2%, but the exact MCLR vintage and any state-specific variations matter.
| State | RERA Interest Rate Formula | Effective Rate (Apr 2026) | Interest Type | Notes |
|---|---|---|---|---|
| Maharashtra | SBI MCLR + 2% | 10.85% | Simple | Most active RERA authority, ~30,000 complaints filed |
| Karnataka | SBI MCLR + 2% | 10.85% | Simple | Online filing available, 8-14 months resolution |
| Tamil Nadu | SBI MCLR + 2% | 10.85% | Simple | Also awards mental agony compensation (Rs 1-2 lakh) |
| Uttar Pradesh | SBI MCLR + 2% | 10.85% | Simple | Covers Noida/Greater Noida, slowest resolution |
| Haryana | SBI MCLR + 2% | 10.85% | Simple | Gurugram projects, heavy caseload |
| West Bengal | SBI MCLR + 2% | 10.85% | Simple | HIRA (state equivalent of RERA) applies |
| Rajasthan | SBI MCLR + 2% | 10.85% | Simple | Online portal launched 2024 |
| Gujarat | SBI MCLR + 2% | 10.85% | Simple | Ahmedabad/Surat heavy volume |
SBI MCLR reference (2025-2026):
| MCLR Tenure | Rate |
|---|---|
| Overnight | 7.90% |
| 1 Month | 8.10% |
| 3 Months | 8.25% |
| 6 Months | 8.65% |
| 1 Year | 8.85% |
RERA uses the 1-year MCLR as the base in most state rulings.
Exact Compensation at Different Flat Values
Here is what you are owed at the current 10.85% rate for common payment amounts and delay periods:
| Amount Paid to Builder | 1-Year Delay | 2-Year Delay | 3-Year Delay | 4-Year Delay |
|---|---|---|---|---|
| Rs 30,00,000 | Rs 3,25,500 | Rs 6,51,000 | Rs 9,76,500 | Rs 13,02,000 |
| Rs 50,00,000 | Rs 5,42,500 | Rs 10,85,000 | Rs 16,27,500 | Rs 21,70,000 |
| Rs 80,00,000 | Rs 8,68,000 | Rs 17,36,000 | Rs 26,04,000 | Rs 34,72,000 |
| Rs 1,00,00,000 | Rs 10,85,000 | Rs 21,70,000 | Rs 32,55,000 | Rs 43,40,000 |
On a Rs 1 crore flat delayed by 3 years, the builder owes you Rs 32.55 lakh. That is not a negotiation — that is Section 18 of the RERA Act.
These numbers assume a flat 10.85% rate. In reality, MCLR changes over the delay period. If MCLR was lower in earlier years (it was 7.40% in 2022), the weighted average rate may be slightly lower. But most RERA orders use the prevailing rate at the time of the order for simplicity.
Section 18: Your Two Options
When your builder misses the possession deadline, RERA Section 18 gives you exactly two choices:
Option A: Terminate and Get Full Refund + Interest
- You withdraw from the project entirely
- Builder must refund every rupee paid — booking amount, installments, GST, everything
- Plus interest at SBI MCLR + 2% on each payment from the date it was made
- Best when: delay exceeds 2 years, builder appears financially unstable, or you have found a better property
Option B: Continue and Collect Monthly Delay Compensation
- You stay in the project and wait for possession
- Builder pays you monthly compensation at SBI MCLR + 2% for the entire delay period
- Compensation runs until actual possession with Occupancy Certificate (OC)
- Best when: delay is under 2 years, property has appreciated significantly, or you genuinely want that specific flat
Which option pays more?
| Scenario | Option A (Refund + Interest) | Option B (Delay Compensation) |
|---|---|---|
| Rs 50L paid, 2-year delay, flat now worth Rs 60L | Rs 60.85L (refund + interest) — you reinvest in a new flat | Keep flat worth Rs 60L + Rs 10.85L compensation = Rs 70.85L total value |
| Rs 50L paid, 3-year delay, builder financially stressed | Rs 66.27L — but execution risk is high if builder is broke | Flat may never complete; you risk losing everything |
| Rs 50L paid, 1-year delay, project 90% complete | Rs 55.42L — but you lose the flat and re-enter the market | Keep flat + Rs 5.42L compensation — better deal |
Bottom line: Option B is better if the flat has appreciated and the builder is solvent. Option A is better if you have lost trust or the builder is in financial trouble. Read our RERA reality check for what actually happens in practice.
Real Case Outcomes — Actual Amounts Awarded
These are not hypothetical numbers. These are actual RERA and appellate tribunal orders:
| Case | Amount Paid | Delay | Compensation Awarded | Forum |
|---|---|---|---|---|
| Abhishek Reddy Gujjala v. Ozone Urbana (Bengaluru) | Rs 31,46,485 | 3+ years | Full refund of Rs 31,46,485 + interest at MCLR + 2% from date of each payment | Karnataka RERA |
| Poomalai Housing (Tamil Nadu, 2024) | Undisclosed | 2+ years | MCLR + 2% interest + Rs 2,00,000 mental agony compensation | Tamil Nadu RERA |
| Various complainants (Tamil Nadu, 2021) | Multiple | 1-3 years | MCLR + 2% interest + Rs 1,00,000 mental agony per complainant | Tamil Nadu RERA |
| Supreme Court — Newtech Promoters v. State of UP (2021) | Multiple | Various | Upheld that RERA interest rate cannot be reduced by agreement; SBI MCLR + 2% is the minimum | Supreme Court |
Key takeaway from the Ozone Urbana case: The buyer received a full refund of Rs 31.46 lakh plus accumulated interest at MCLR + 2% from the date of each payment. On a 3-year delay, the interest component alone was approximately Rs 10.2 lakh.
Tamil Nadu RERA stands out for awarding mental agony compensation on top of the statutory interest — Rs 1-2 lakh in most cases. Other states rarely award this.
The Execution Crisis — Winning Is Not the Same as Getting Paid
Here is the uncomfortable truth that no builder association will tell you: getting a RERA order is easy; getting the money is hard.
The numbers from Maharashtra tell the story:
- 176 execution warrants issued by MahaRERA (as of 2024)
- Only 1 fully executed — the builder actually paid
- Remaining 175 cases: builders either appealed, delayed, or simply ignored the warrant
This is the biggest gap in RERA enforcement. The authority can pass orders, but it lacks the teeth of a civil court for property attachment and arrest.
What happens after you win a RERA order:
- Builder gets 45 days to comply with the order (Section 40)
- If builder does not pay, you file an execution petition with the RERA authority
- RERA can issue a Recovery Certificate (like a civil court decree)
- The Recovery Officer can then:
- Attach the builder’s movable and immovable property
- Freeze the builder’s bank accounts
- Issue an arrest warrant against the builder/promoter
- If RERA execution fails, you can approach the District Collector for recovery as arrears of land revenue
Realistic timelines:
| Stage | Expected Duration |
|---|---|
| RERA complaint to order | 6-18 months |
| Builder compliance (if cooperative) | 1-2 months |
| Execution petition filing to action | 6-12 months |
| Actual recovery after execution | 3-6 months |
| Total (worst case) | 15-36 months |

Step-by-Step: How to File and Enforce a RERA Delay Compensation Claim
Step 1: Gather Documents
- Registered sale agreement or allotment letter (with possession date clause)
- All payment receipts — bank statements showing transfers to builder
- Builder’s communication regarding delay (emails, letters, WhatsApp messages)
- RERA registration number of the project (verify at how to check RERA registration)
Step 2: Calculate Your Claim
Use the formula: Amount Paid x 10.85% x Years Delayed
For installment-based payments, calculate interest on each installment separately from its payment date.
Step 3: File Online at Your State RERA Portal
| State | RERA Portal | Filing Fee |
|---|---|---|
| Maharashtra | maharera.maharashtra.gov.in | Rs 5,000 |
| Karnataka | rera.karnataka.gov.in | Rs 5,000 |
| Tamil Nadu | tnrera.in | Rs 1,000 |
| Uttar Pradesh | up-rera.in | Rs 1,000 |
| Haryana | haryanarera.gov.in | Rs 1,000 |
| Gujarat | gujrera.gujarat.gov.in | Rs 1,000 |
Step 4: Attend Hearings (or Authorize a Representative)
- Most hearings are now hybrid — online video conferencing available
- NRIs can authorize a representative via Power of Attorney
- Typically 3-6 hearing dates over 6-12 months
Step 5: If Builder Does Not Comply — File Execution Petition
- File under Section 40 of the RERA Act
- Attach proof that 45 days have passed since the order
- Request property attachment and bank account freeze
- Consider filing simultaneously in Consumer Court for broader relief
Step 6: Explore the Section 40 Penalty Route
Under Section 63 of RERA, non-compliance with RERA orders can result in:
- Imprisonment up to 3 years for the builder/promoter
- Fine up to 10% of the estimated project cost
- Or both
This is a criminal penalty — a powerful leverage tool even if rarely invoked.
When to Choose Consumer Court Instead of RERA
RERA is not always the best forum. Here is when Consumer Court is the smarter choice:
| Factor | RERA | Consumer Court (NCDRC/State/District) |
|---|---|---|
| Compensation type | Interest only (MCLR + 2%) | Interest + mental agony + rental + litigation costs |
| Mental agony | Rs 0-2 lakh (rare, Tamil Nadu exception) | Rs 3-10 lakh (routinely awarded) |
| Rental compensation | Not typically awarded | Can be awarded (Rs 15,000-50,000/month) |
| Claim limit | No limit | District: up to Rs 50 lakh; State: up to Rs 2 crore; NCDRC: above Rs 2 crore |
| Timeline | 6-18 months | 12-36 months |
| Execution | Weak (execution crisis) | Stronger civil court powers |
| Lawyer needed | Optional | Recommended |
Choose Consumer Court when:
- Your builder is a repeat offender and you want punitive damages
- You have been paying rent due to the delay and want rental compensation
- Your total claim (including mental agony, rental, litigation) exceeds the RERA interest amount
- RERA execution has failed and you need civil court enforcement
Choose RERA when:
- You want a faster initial order
- Your claim is primarily about interest on delayed possession
- The builder is cooperative but slow

Carpet Area Shortfall — The Other Compensation You Might Be Owed
Under Section 14 of RERA, builders are allowed a maximum deviation of 3% from the agreed carpet area. Beyond that, you are entitled to a proportionate refund.
| Agreed Carpet Area | Delivered Carpet Area | Shortfall | Allowable (3%) | Compensable Shortfall | Flat Cost | Refund Owed |
|---|---|---|---|---|---|---|
| 1,000 sq ft | 960 sq ft | 4% | 3% | 1% (10 sq ft) | Rs 80,00,000 | Rs 80,000 |
| 1,000 sq ft | 940 sq ft | 6% | 3% | 3% (30 sq ft) | Rs 80,00,000 | Rs 2,40,000 |
| 1,200 sq ft | 1,100 sq ft | 8.3% | 3% | 5.3% (64 sq ft) | Rs 1,20,00,000 | Rs 6,40,000 |
Get the carpet area independently measured before taking possession. The builder’s measurement is not the final word.
The 5-Year Structural Defect Warranty — Do Not Forget It
Once you do get possession, RERA provides a 5-year warranty on structural defects and workmanship. If the ceiling leaks, walls crack, or plumbing fails within 5 years of possession, the builder must fix it at no cost to you.
This is a separate right from delay compensation. Read the full guide: RERA 5-year warranty — how to claim for structural defects.
What You Should Do Right Now
- Check your agreement — note the exact possession date clause and total amount paid
- Calculate your compensation — use Rs (Amount Paid) x 10.85% x (Years Delayed)
- Send a legal notice — registered post to the builder citing Section 18 of RERA, demanding MCLR + 2% interest
- File online — if no response within 30 days, file at your state RERA portal
- Prepare for execution — have your execution petition ready before the order is even passed
The money is yours by law. The only question is whether you will claim it.
