Price per sqft in India: how carpet, built-up and super built-up area change the rate
Price per square foot (₹/sqft) is the single most used yardstick in Indian real estate — for resale flats, new launches, plots and commercial space alike. But the same property can be advertised at three different rates depending on whether the builder divides the price by carpet area, built-up area or super built-up area.
The three area definitions you must separate
Carpet area is the usable floor area inside your walls — the area you can actually lay a carpet on, including internal partition walls but excluding the external wall, shaft, balcony and terrace. Under RERA (Real Estate (Regulation and Development) Act, 2016), builders must declare carpet area in the agreement.
Built-up area adds the thickness of walls, ducts and usually the balcony — typically 10–15% above carpet. Super built-up area additionally loads your share of common areas: lobbies, staircases, lifts, clubhouse, corridors and sometimes amenity decks.
- Carpet area — usable internal area, the RERA-mandated figure
- Built-up area — carpet + walls + balcony (roughly carpet × 1.10–1.15)
- Super built-up (saleable) area — built-up + share of common areas
- Loading factor — the percentage gap between carpet and super built-up, commonly 20–40%
How to normalise any quote to carpet ₹/sqft
Ask for the agreement value and the RERA carpet area, then divide. A ₹1.20 crore flat with 900 sqft carpet is ₹13,333/sqft carpet, even if the brochure advertises ₹9,600/sqft on a 1,250 sqft super built-up area. Comparing a carpet rate against a super built-up rate is the most common costing mistake buyers make.
On Estatly.in the area-wise ₹/sqft figures are indicative market rates for a locality, useful for ranking and trend reading — always re-derive the exact rate for a specific unit from its agreement value and RERA carpet area.
What else moves the rate inside one locality
Micro-market rates vary widely within a single pin code. Frontage on an arterial road, metro walkability, floor rise charges, corner or park-facing units, vaastu-compliant orientation, project age, builder brand premium and the quality of the OC/CC paperwork all shift the achievable ₹/sqft.
- Floor rise: often ₹25–₹100 per sqft per floor in high-rises
- Preferred location charges (PLC) for park, corner or road-facing units
- Metro or expressway proximity — usually the strongest single driver
- Project age and lift/podium condition in resale stock
Costs that sit on top of the quoted rate
The headline ₹/sqft rarely includes stamp duty and registration, GST on under-construction property, club membership, corpus fund, parking, infrastructure development charges, or interiors. Build the full landed cost before comparing two localities.
Frequently asked questions
Is carpet area or super built-up area used for price per sqft in India?
Brochures usually advertise ₹/sqft on super built-up (saleable) area because it produces a lower-looking number, while RERA agreements must state carpet area. For any real comparison, divide the total agreement value by RERA carpet area.
What is a normal loading factor?
Loading of 20–30% is common in mid-segment projects and 30–40% in amenity-heavy high-rises. Anything above 40% means you are paying a large share for common areas.
Does a higher ₹/sqft mean a better investment?
No. High-rate localities are often already mature with slower growth, while emerging corridors can show stronger YoY appreciation from a lower base. Read rate and YoY change together.
