Carpet Area vs Built-Up Area: What You Need to Know

Understanding real estate jargon is crucial when buying a property. One of the most misunderstood concepts in Indian real estate is the difference between carpet area, built-up area, and super built-up area. Let’s break them down clearly so you know exactly what you’re paying for.

1. What is Carpet Area?

• Definition: The actual usable area within the walls of your flat. Think of it as the area where you can lay a carpet.

• Includes: Bedroom, living room, kitchen, bathrooms, internal partition walls

• Excludes: Balcony, terrace, external walls, common areas

Tip: Carpet area is the most accurate reflection of usable space in a home.

2. What is Built-Up Area?

• Definition: Carpet area + thickness of internal/external walls + balcony

• Typically: 10–20% more than the carpet area

• Includes: Carpet area + wall thickness + balcony/veranda

Builders used to quote prices based on built-up area, but now RERA mandates carpet area disclosure.

3. What is Super Built-Up Area?

• Definition: Built-up area + proportionate share of common areas

• Includes: Lobbies, lifts, staircases, clubhouse, and other shared amenities

Also known as the “saleable area,” it's used to calculate the price per sq. ft. before RERA regulation came into effect.

4. Why It Matters

• Price Clarity: Always compare carpet area across projects for a true value comparison

• Loan Approval: Banks consider carpet area when evaluating property for home loans

• Transparency: RERA has made it mandatory to sell homes based on carpet area only

5. Sample Comparison

Area Type Square Feet
Carpet Area 600 sq. ft.
Built-Up Area 720 sq. ft.
Super Built-Up Area 900 sq. ft.
A property priced at ₹20,000/sq.ft. may seem expensive, but it depends on what area that rate is being applied to.
