RERA delay compensation calculator for Maharashtra

Staying in the project. Section 18(1) of the Real Estate (Regulation and Development) Act, 2016 says a buyer who doesn't withdraw is paid interest for every month of delay, until possession is handed over. The calculator charges simple interest on everything you've paid the promoter, from the possession date in your agreement to the day you get possession. A payment made after that date earns interest from the day you made it.

Withdrawing. A buyer who withdraws gets back the amount paid with interest at the same rate, so each payment earns interest from the day it was made until the refund.

The rate. The Maharashtra RERA rules set the interest rate at the State Bank of India's highest marginal cost of lending rate (MCLR) plus 2%. SBI's highest MCLR is the 3-year rate, 8.95% from 15 October 2026 (SBI MCLR rates), which makes the rate 10.95%. Orders usually apply the rate in force when they are passed, so you can change it in the calculator.

A buyer paid ₹60,00,000 towards a flat with possession promised on 30 June 2023, and got the keys on 30 June 2025: a delay of 731 days. At 10.95% a year:

Amount paid

₹60,00,000

Rate × days

10.95% × 731/365

Delay

731 days

Interest

₹13,15,800

Had the flat still not been handed over, the amount would grow by about ₹54,750 each further month.

• The date in your agreement, not the RERA registration. The calculator fills in the completion date the promoter first declared to MahaRERA, but the possession date in your agreement for sale is the one that counts. A later completion date on MahaRERA, or an extension of the project's registration, doesn't by itself change your agreement.
• The 2020 COVID moratorium. MahaRERA Order No. 14/2020 declared 15 March to 14 September 2020 a force majeure period, extended possession dates in agreements already registered by that period, and said it is treated as a moratorium when calculating interest under Section 18. Tick the box to leave those 184 days out. The 2021 second-wave order extended project registrations but said this doesn't affect buyers' rights, so the calculator doesn't exclude it.
• What counts as paid. Count what you paid the promoter. Stamp duty and registration fees go to the government and are usually left out.
• Simple interest. The calculator uses simple interest, as MahaRERA orders generally do. Compensation for other losses is decided separately by the adjudicating officer.

Ask the promoter in writing first, quoting the agreement date and Section 18. If that fails, a complaint can be filed online on the MahaRERA portal. Before you do, look up the project's record: extensions granted, complaints and orders already passed against it, and whether its registration has lapsed.

For the bigger picture, see how many MahaRERA projects are delayed and which have lapsed, by district and locality.
