Frequently Asked Questions (FAQs)
Everything property buyers, brokers, and developers need to know about carpet area rules and cost calculations.
What is the definition of Carpet Area under RERA?
Under Section 2(k) of the Real Estate (Regulation and Development) Act, 2016 (RERA), "Carpet Area" is defined as the net usable floor area of an apartment, excluding the area covered by external walls, areas under service shafts, exclusive balcony or verandah area, and exclusive open terrace area, but including the area covered by the internal partition walls of the apartment. Builders are legally mandated to sell property based solely on RERA carpet area.
What is "Loading Percentage" in Indian real estate?
Loading percentage represents the difference between the Super Built-Up (Saleable) Area and the RERA Carpet Area. It accounts for the proportionate share of common areas such as lobbies, staircases, elevators, clubhouses, and security kiosks. In Indian metro apartments, loading typically ranges from 20% to 35%. Formula: Super Built-Up Area = Carpet Area × (1 + Loading % / 100).
How are Stamp Duty and Registration Charges calculated in India?
Stamp duty is a state-level transaction tax payable upon registering property conveyance deeds, generally ranging from 4% to 7% of the agreement value or government circle rate (ready reckoner rate), whichever is higher. Registration fees typically add 1% to 2%. Our calculator applies state-specific presets across Maharashtra, Karnataka, Delhi-NCR, Tamil Nadu, and UP.
