How To Calculate Carpet Area - Carpet Area Calculator
Understanding the intricacies of property measurement, particularly the concepts of carpet area, built-up area, and super built-up area, is crucial for prospective homebuyers and real estate enthusiasts. These terms play a significant role in determining the value, pricing, and overall utility of residential properties. The carpet area represents the actual usable space within an apartment, while the built-up area includes additional elements like walls and balconies. A super built-up area, often termed the ‘saleable area,’ encompasses the built-up area along with shared amenities and common spaces. This comprehensive guide aims to explore these concepts in detail, providing insights into their calculation methods, significance, a carpet area calculator, and practical implications in the realm of real estate.
What is a Carpet Area?
The carpet area refers to the net usable area within an apartment, encompassing the space between inner walls and including rooms such as bedrooms, living rooms, kitchens, bathrooms, balconies, and staircases. It excludes external and internal walls, terraces, common areas, lifts, corridors, and utility ducts.
What is the RERA Carpet Area?
As per the RERA Act 2016, the RERA Carpet Area denotes the net usable floor space of an apartment or house, excluding external areas, common areas, exclusive balconies or verandas, and exclusive open terraces, while including the area covered by internal partition walls.
Please note: In this context, “exclusive balcony or veranda area” refers to the portion of the balcony or veranda attached to the net usable floor space of an apartment, designated exclusively for the allottee’s (house owner’s) use; and “exclusive open terrace area” refers to the section of an open terrace linked to the net usable floor space of an apartment, reserved solely for the allottee’s (house owner’s) use.
What Distinguishes the RERA Carpet Area from the Carpet Area?
The sole distinction lies in the inclusion of the thickness of internal partition walls. RERA Carpet Area incorporates the thickness of internal walls, whereas general Carpet Area does not. This results in approximately a 5% difference between the two, with the RERA Carpet Area being 5% larger than the general carpet area calculator.

How to Determine Carpet Area & RERA Carpet Area?
For General Carpet Area Calculation:
Use the formula: Carpet area = (area of bedroom + living room + kitchen + balconies + toilets) – thickness of inner walls.
Typically, the carpet area constitutes between 70% to 90% of the total built-up area of an apartment.
Example:
Let’s consider an apartment with a 1392.65 sq. ft. built-up area, where 82.8% represents the General Carpet Area. Thus, 82.8% of 1392.65 sq. ft. equals 1153.11 sq. ft., which is the General Carpet Area.
For RERA Carpet Area Calculation:
According to The RERA Act 2016, calculate the RERA Carpet Area by adding the net usable area of the apartment (excluding external walls, terrace area, balcony area, and verandah area) to the areas of the internal partition walls.
Note that there’s typically a 5% difference between the General Carpet Area and the RERA Carpet Area. For instance, if the General Carpet Area is 1153.11 sq. ft., the RERA Carpet Area would be approximately 1211 sq. ft.
After talking about carpet area and a carpet area calculator, let’s move on to the built-up area.
What is a Built-up Area?
The built-up area encompasses the carpet area plus additional space occupied by exterior and interior walls, balconies, exterior staircases, and other livable areas if applicable. Exclusive terraces are also included in the built-up area calculation. Typically, the built-up area constitutes around 70-80% of the super built-up area.
How to Calculate Built-up Area?
To calculate the built-up area, add the Carpet Area or RERA Carpet Area, along with the areas of both interior and exterior walls, exclusive balcony, and corridor if applicable.
Built-up Area = Carpet Area + Wall Areas + Terrace and Balcony + Exclusive Corridor
Typically, the built-up area exceeds the Carpet Area by 10% to 15%. For example, if your RERA Carpet Area is 1211 sq. ft., then the built-up area would range between 1332.1 sq. ft. and 1392.65 sq. ft.
Carpet Area Vs Built-up Area Comparison
- The Carpet Area, as per RERA standards, encompasses the bedroom, living room, kitchen, balconies, toilets, and the thickness of internal partition walls. In contrast, the built-up area includes the Carpet Area along with the external wall area, terrace or balcony space, and any exclusive corridor.
- The Built-up Area always exceeds the Carpet Area and excludes common areas like lifts, security rooms, lobbies, and clubhouses.
What is a Super Built-up Area?
The super built-up area, also known as the ‘saleable area,’ determines the value that homebuyers are charged. It comprises the exclusive built-up area and common areas such as lifts, corridors, staircases, clubhouse, and other amenities. However, it excludes certain elements like compound walls, open-to-sky swimming pools, parks, driveways, and underground utilities like water tanks and septic tanks.
The proportionate share of common areas is denoted by the “Loading Factor,” typically ranging from 25% to 60% of the carpet area. For instance, with a loading factor of 50% and a carpet area of 1211 sq. ft., the super built-up area would be 1816 sq. ft.
How to Calculate Super Built-up Area?
The super built-up area is determined by adding the built-up area to the proportionate common area. Alternatively, it can be calculated by multiplying the carpet area by 1 plus the loading factor.
For example, with a loading factor of 50%:
1211 sq. ft. (RERA Carpet) x (1 + 0.50) = 1816 sq. ft.
Additionally, in a scenario where two apartments on the same floor share a common area, the builder allocates the common area based on the ratio of their built-up areas. For instance, if one flat is 1000 sq. ft. and another is 2000 sq. ft., and the total common area is 1500 sq. ft., the ratio is 1:2. Consequently, the builder would allocate 500 sq. ft. to the first apartment and 1000 sq. ft. to the second. Thus, the super built-up area of the first property becomes 1500 sq. ft. and that of the second property becomes 3000 sq. ft.
Conclusion - Carpet Area to Built-up Area
Understanding carpet area, built-up area, and super built-up area is crucial for navigating the real estate market effectively. These measurements determine the value and utility of properties. By knowing these concepts, buyers can make informed decisions, and developers can communicate property specifications. Simplifying these terms empowers everyone involved in real estate to make confident choices and foster transparency in the industry.
