Carpet Area Calculator
About the Carpet Area Calculator
The Carpet Area Calculator is a helpful online tool designed to calculate the carpet area, built-up area, and super built-up area of a property. These three terms are vital in real estate transactions, as they directly affect property pricing, usable space, and legal documents. Whether you’re a homebuyer, builder, or real estate consultant, this calculator provides instant results for accurate planning.
What is Carpet Area?
The Carpet Area is the actual usable area within the walls of a house — the space where you can lay a carpet. It excludes the thickness of walls, balconies, and common areas. Carpet area typically makes up around 70–80% of the super built-up area.
Built-up Area vs Super Built-up Area
- Built-up Area: Carpet area + wall thickness + balcony or terrace space.
- Super Built-up Area: Built-up area + proportionate share of common areas (like stairs, lobbies, and lifts).
This calculator helps you derive all three values if you know the total built-up area and the approximate percentages of wall and common areas.
Formula Used
- Carpet Area = Built-up Area × (1 − Wall % / 100)
- Super Built-up Area = Built-up Area × (1 + Common % / 100)
Example Calculation
Suppose the built-up area is 1200 sq ft, wall thickness is 10%, and common area share is 25%.
Carpet Area = 1200 × (1 − 0.10) = 1080 sq ft
Super Built-up Area = 1200 × (1 + 0.25) = 1500 sq ft
Why is Carpet Area Important?
When purchasing a flat or apartment, the carpet area determines the space you can actually use. Builders often advertise super built-up area, but legal agreements (under RERA) must now mention the exact carpet area. Knowing this helps buyers make informed comparisons and ensures transparency in real estate transactions.
