Notice to Builder for Delay in Handing over the Possession

RERA Interest for Delayed Possession

The Real Estate (Regulation and Development) Act, 2016 (RERA) provides strong protection for homebuyers against delays by builders. One key provision is the builder's liability to pay interest for every day of delay in handing over possession of the property.

How is the Interest Calculated?

The standard rule across most Indian states stipulates that if the builder fails to give possession by the date promised in the agreement, they must pay interest to the homebuyer. The interest is calculated on the total amount paid by the homebuyer for the property.

The formula is:
Interest = Total Amount Paid × (Annual Interest Rate / 100) × (Delay Period in Days / 365)

  • Total Amount Paid: The sum of all installments, booking amounts, and other payments made to the builder.
  • Annual Interest Rate: This is the State Bank of India's (SBI) highest Marginal Cost of Funds based Lending Rate (MCLR) plus 2%. This rate is revised frequently by SBI, and state RERA authorities notify the applicable rate periodically.
  • Delay Period: The number of days from the promised possession date (after any applicable state-specific grace period) until the date you actually receive possession or the date up to which you are claiming. Interest only accrues if this period is positive.

Example Calculation

Suppose you booked an apartment in Maharashtra for ₹50,00,000. The promised possession date was 1st January 2025, but you have not received it yet. Maharashtra allows a 90-day grace period. As of 20th October 2026, the delay starts after 1st April 2025 (90 days later). Assuming the applicable interest rate is 8.65% per annum:

  • Grace Period: 90 days.
  • Interest Start Date: 1st April 2025.
  • Delay Period: From 1st April 2025 to 20th October 2026 = 568 days.
  • Delay in Years: 568 / 365 ≈ 1.5562 years.
  • Interest Payable: ₹50,00,000 × (8.65 / 100) × 1.5562 ≈ ₹6,73,000.
  • The builder would owe you approximately ₹6.73 lakhs in interest as compensation for the delay.

State-Specific Variations

While the central RERA Act sets the framework, state RERA authorities have specific regulations. Key variations include:

  • Grace Period: Some states, like Maharashtra, allow a grace period (e.g., 90 days) after the promised date before interest starts accruing. Other states may not.
  • Interest Rate: The exact method of determining and notifying the SBI MCLR + 2% rate is specified by each state authority. You must use the rate officially declared for your state at the time of calculation.
  • Compounding: The Act is generally interpreted to mandate simple interest, but your agreement or state rules should be checked.

It is crucial to refer to the website of your state's RERA authority for the most precise and up-to-date information on grace periods and interest rates.

What Should You Do Next?

If you are facing a delay, follow these steps:

  1. Calculate Your Dues: Use this calculator to estimate the interest payable. Ensure you have the correct, current interest rate from your state RERA.
  2. Formal Notice: Send a formal legal notice to the builder, citing the RERA provisions and your calculated demand. This serves as an official record and often prompts action.
  3. RERA Complaint: If the builder does not respond satisfactorily, you can file a complaint with your state's RERA authority. The process is designed to be faster than traditional courts.
  4. Legal Counsel: For significant amounts or complex cases, consulting a lawyer specializing in real estate law is advisable.

After calculating your interest, the next logical step is to prepare a Notice to Builder for Delay in Handing over the Possession. This document formally communicates your demand for compensation or possession.

Frequently asked questions

What is the RERA interest rate for delayed possession?

The standard rate is the State Bank of India's (SBI) highest Marginal Cost of Funds based Lending Rate (MCLR) plus 2% per annum. This rate changes frequently. You must check the latest notification from your state's RERA authority for the exact applicable rate at the time of your calculation.

Does the grace period affect interest calculation?

Yes, in some states. For example, Maharashtra's RERA rules commonly include a 90-day grace period after the promised possession date before interest starts accruing. Our calculator uses a table of state-specific grace periods; verify the rule for your state.

Is interest calculated on the total agreement value or the amount paid?

Interest is calculated on the total amount you have actually paid to the builder, not on the full agreement value of the property.

What if I haven't received possession yet?

You can calculate interest up to today's date or any future date. The builder's liability continues until they legally offer possession. Use the 'Calculation Date' field for this purpose. If the calculation date is before the promised date (plus grace), no interest is payable.

Can I cancel the booking and get a refund with interest?

Yes, under RERA, if the delay exceeds the time specified in the law (often one year after the promised date), you have the right to withdraw from the project. The builder must return your entire payment with interest within 45 days.

How do I find my state's current RERA interest rate?

Visit the official website of your state's RERA authority (e.g., MahaRERA for Maharashtra, UP-RERA for Uttar Pradesh). Look for circulars, notifications, or a dedicated section for 'Interest Rate' which specifies the applicable SBI MCLR + 2% rate for the current period.
