What is carpet area and how is it different from super area?

Carpet area is the net usable area inside your apartment — the area where you can literally lay a carpet. It excludes walls but includes internal rooms, kitchen, bathrooms, and balconies. Under RERA, carpet area is the legally defined measurement. Carpet area is typically 65–75% of the super area in Gurgaon projects.

What is saleable area?

Saleable area is the total area on which the builder charges you — usually equal to or larger than super area. It may include terraces, sit-outs, garden areas, and utility spaces that are sold at a proportionate rate. In most Gurgaon projects, saleable area = super area.

How do I calculate the true price per sq.ft. of an apartment?

To get the true cost, divide the total price by the carpet area (not super area). For example, if a 1,500 sq.ft. super area apartment costs ₹1.5 Cr and the carpet area is 1,050 sq.ft. (70% loading), the effective rate is ₹1.5 Cr ÷ 1,050 = ₹14,285 per sq.ft. of usable space — not the advertised ₹10,000/sq.ft.

Super Area vs Carpet Area vs Saleable Area in Real Estate — What Every Buyer Must Know

Q: What is super area in real estate?

Super area (also called gross area or built-up area) is the total area including your apartment's walls, balconies, terraces, and a proportionate share of common areas like lobby, lift, staircase, and club amenities. Builders quote prices on super area, which is always larger than the carpet area you actually live in.

Q: What does RERA say about carpet area?

Under RERA (Real Estate Regulation and Development Act), builders are legally required to disclose the carpet area of the unit and must only charge for the carpet area and proportionate common areas separately. Builders cannot increase the carpet area by more than 3% after registration without buyer consent.

TL;DR — KEY TAKEAWAYS

Carpet area = actual usable space inside your flat (RERA-defined, legally binding)
Super area = carpet area + walls + your share of lobby, lift, stairs, clubhouse
Saleable area = the area builders charge you for — usually equals super area
In Gurgaon, carpet area is typically 65–72% of super area (loading factor 28–35%)
Always ask the builder for carpet area; compare price/sq.ft. on carpet area — not super area

When a builder says "2,000 sq.ft. apartment at ₹15,000/sq.ft.", what exactly are you paying for? Most buyers assume they're getting 2,000 sq.ft. of liveable space. They're not. Understanding the difference between super area, carpet area, and saleable area is the single most important calculation before signing any real estate agreement in India.

The Three Area Types — Explained Simply

✓ RERA Defined

Carpet Area

The net usable floor area inside your apartment — measured wall to wall. Includes bedrooms, living room, kitchen, bathrooms, internal corridors, and balconies. Excludes walls.

Commonly Quoted by Builders

Super Area

Carpet area + wall thickness + your proportionate share of common areas (lobby, lift shaft, staircase, generator room, club, amenity deck). Always larger than carpet area.

What You Pay For

Saleable Area

The total area a builder charges you. In most Gurgaon projects saleable = super area. In some projects it may additionally include terrace or private garden charged at a reduced rate.

The Loading Factor — How Much Are You Losing?

The loading factor (or load factor) is the difference between super area and carpet area, expressed as a percentage. A 30% load means 30% of the super area you pay for is common space — not usable by you privately.

Typical Loading Factors in Gurgaon 2026

High-rise luxury

28–35%

Mid-rise towers

24–28%

Builder floors

10–18%

Plotted villas

0–8%

Higher loading = more premium amenities (larger clubhouse, wider lobbies, sky decks) but less private usable area.

Real-World Example — Gurgaon 2026

Let's say you're looking at a 3 BHK on Dwarka Expressway quoted at 1,800 sq.ft. super area at ₹16,500/sq.ft. — total price ₹2.97 Cr.

Calculation	Super Area Basis	Carpet Area Basis
Area quoted	1,800 sq.ft.	1,260 sq.ft. (70% of super)
Price per sq.ft.	₹16,500	₹23,571 (effective)
Total price	₹2.97 Cr	₹2.97 Cr
Usable bedroom space	~	What you actually live in

The effective rate on usable (carpet) area is ₹23,571/sq.ft. — 43% higher than what the builder advertises. This is not a scam — it's how the industry works. But you must calculate it before comparing projects.

What Does RERA Say?

The Real Estate (Regulation and Development) Act, 2016 brought major clarity:

Builders must disclose carpet area in all agreements — it is the only legally binding measurement
The builder cannot increase carpet area by more than 3% after RERA registration without buyer consent
If carpet area decreases by more than 3%, the buyer is entitled to a proportionate refund
RERA mandates carpet area includes balconies (changed in 2017 amendment)
Always verify carpet area on haryanarera.gov.in for Gurgaon projects — it is publicly disclosed

Pro Tip: Before booking, ask the builder for the RERA carpet area certificate. Cross-check it against the floor plan. The difference between what's on the brochure (super area) and the RERA certificate (carpet area) tells you the exact loading factor.

Typical % of super area	65–75%	100% (reference)	100–110%

Builder Floor vs High-Rise — Area Type Impact

This distinction is especially important when comparing builder floors in Sector 57 Gurgaon vs high-rise apartments on Dwarka Expressway or Golf Course Road.

Builder floors typically have loading of only 10–18% because there are no high-rise common areas (no lift lobby serving 40 floors, no sky deck, no massive clubhouse). A 2,000 sq.ft. super area builder floor gives ~1,700 sq.ft. carpet area.
High-rise luxury towers on Dwarka Expressway (like Adani The Marq or Godrej Vriksha) have loading of 28–35% because of 35,000–90,000 sq.ft. clubhouses, sky bridges, multiple pool decks, etc.
The loading is not "wastage" — it's the amenity premium you're paying for. The question is whether you will use those amenities.

How to Calculate True Price Per Sq.Ft. (Step-by-Step)

Get the RERA carpet area from the builder or haryanarera.gov.in
Get the total all-inclusive price (BSP + PLC + parking + EDC/IDC + IFMS + GST)
Divide: True rate = Total price ÷ Carpet area
Now compare this number across all projects you are evaluating

Frequently Asked Questions

What is super area in real estate?

Super area (also called gross area) is the total area including your apartment's internal space, walls, and a proportionate share of common areas like lobby, lift, staircase, clubhouse, and amenity floors. Builders in India quote prices on super area, which is always larger than the usable carpet area. In Gurgaon's luxury high-rises, super area is typically 28–35% more than carpet area.

What is carpet area and is it different from super area?

Yes, carpet area and super area are different. Carpet area is the net usable floor space inside your apartment — measured wall to wall — where you can literally lay a carpet. It includes bedrooms, living room, kitchen, bathrooms, and balconies but excludes walls. Super area includes carpet area plus walls and common area allocation. Carpet area is typically 65–75% of super area in Gurgaon towers. Under RERA, carpet area is the only legally binding measurement.

What does saleable area mean?

Saleable area is the total area a builder charges you. In most Gurgaon projects, saleable area equals super area. In some premium projects, saleable area may additionally include private terrace, garden, or utility space sold at a concessional rate. Always ask the builder to clarify what exactly is included in the saleable area before signing the booking form.

What does RERA say about carpet area?

Under RERA 2016, builders must disclose and use carpet area as the official measurement in all legal agreements. They cannot charge on super area basis in the allotment letter. The carpet area cannot increase by more than 3% post registration without buyer consent. If it decreases by more than 3%, buyers are entitled to a refund. For Haryana projects, verify on haryanarera.gov.in.

Why is the effective price per sq.ft. higher than advertised?

Because builders advertise price per sq.ft. on super area, but you actually get carpet area — which is 65–75% of super area. If a project is quoted at ₹15,000/sq.ft. on 1,800 sq.ft. super area, and the loading factor is 30%, the carpet area is 1,260 sq.ft. The effective rate on usable space is ₹15,000 × (1,800/1,260) = ₹21,428/sq.ft. This is the true comparison number.
