You must have come across various words and lingo used by real estate brokers and developers in India that have left you all perplexed and in the dark! We created this article to explain what built-up, super-built, and carpet areas mean. The purpose of such informational articles is to increase your knowledge so that any risk you may have of becoming ignorant is wholly eliminated. Let's get to the material in this article without further ado and see what it offers.

Carpet Area: Meaning

You and many other people in India are currently surfing the internet for "carpet area means." But don't fret! We will provide you with all the information about the carpet area in the simplest form. The area of an apartment that a carpet can easily cover is basically what "carpet area" means. It is the distance between the inner walls and includes some areas like kitchens, bathrooms, verandas, living rooms, bedrooms, and staircases available within the apartment. However, the carpet area does not include external and internal walls, terraces, or common areas like lifts, lobbies, etc.  

RERA Carpet Area: Meaning 

According to the Real Estate Regulatory Authority (RERA) 2016, carpet area means an apartment's net usable floor area. Still, it does not include external walls, areas under service shafts, exclusive balconies, verandahs, or open terraces. 

A point to keep in mind

As was already noted, "exclusive balconies or verandahs" refer to the space they cover, depending on the situation. It is attached to an apartment's net usable floor area and is only available to the home's owner. Moreover, a private outdoor terrace area is a portion of the apartment's net usable floor space and is exclusively for the homeowner's use.

Is there a difference between 'RERA Carpet Area' and 'Carpet Area'?

• The thickness of the internal partition walls is the difference between the RERA carpet area and the carpet area.

• The RERA Carpet Area Means: The thickness of the internal walls is included, whereas in the "General Carpet Area," it is excluded. 

• All in all, there is a 5% difference between the carpet areas. 

• The RERA Carpet Area is larger by 5% than the general carpet area.

Steps to Calculate Carpet Area and RERA Carpet Area

The formula for the general carpet area

Carpet Area= (Area of the bedroom + living room + kitchen + balconies + toilets) - The thickness of the inner walls. 

To better understand, let's look at an example of a carpet area calculation for an entire apartment:

Let's say an apartment has a built-up area of 1500 square feet, and the general carpet area makes up 85% of that space. The General Carpet Area is 1275 square feet or 85% of 1500 square feet.

According to the RERA Act, real estate developers must inform homebuyers about the carpet area of any property. The developers also have to specify the super built-up area to the carpet area. 

The homebuyer also holds the right to get the ratio of carpet area to the built-up area. The space is calculated based on the ratio of both the carpet area and the built-up area.

The formula for RERA Carpet 

RERA Carpet Area = Net Apartment Usable Area + Internal Partition Wall Areas

NOTE: An apartment's net usable area does not include the external walls, terrace area, balcony area, or verandah area.

As was mentioned earlier, there is a 5% difference between the RERA Carpet Area and the General Carpet Area. If your general carpet area is 1275 square feet, the RERA carpet area will be 1338.75 square feet.

Built-up area: Meaning

You must measure a space's built-up area starting from the exterior and interior perimeter wall surfaces if you want to determine how much space is occupied. Even the terrace area is also included. For details, please see below.

Built-up area = carpet area + wall area + balcony area + exclusive corridor

Built-Up Area: Calculation 

If 1500 sq ft is the built-up area, the carpet area would not be more than 1050 sq ft.

NOTE-The built-up area is mainly 15–30% of the carpet area. 

Carpet Area vs. Built-Up Area 

• In accordance with RERA, the built-up area is the sum of the carpet area, external wall area, terrace or balcony area, if any, and the areas of the bedroom, living room, kitchen, balconies, bathrooms, and internal partition walls.

• The built-up space consistently exceeds the carpeted area and does not include common areas like the elevator, security room, lobby, clubhouse, etc.

Super Built-Up Area: Meaning

The saleable area is the super built-up area. Homebuyers typically charge based on this amount. The total built-up area, or super built-up area, is the product of the individual built-up areas and the shared spaces such as the elevators, stairways, and common areas.

Nevertheless, the super built-up area does not include swimming pools, parks, driveways, sports facilities, playgrounds, or water tanks. 

The "Loading Factor," which is given a figure that typically varies from 25% to 60% of the carpet surface, designates the proportionate share of shared areas.

If the loading factor is 40% and your carpet area is 240 sq. ft., then the super built-up area would be 1785 sq. ft.

Super Built-Up Area: Calculation 

You can determine the super-built area by combining the built-up area and the proportional common area. Alternatively, you can compute it by multiplying the carpet by a loading factor plus one.

Let's say you have a 1500-square-foot apartment on the third floor and your cousin has a 2000-square-foot apartment on the same level. The builder would divide the shared space in proportion to the built-up area if the total joint area were 1,500 square feet.

In this instance, the ratio is 3:4. The builder will increase your flat by 643 square feet while giving your cousin an additional 857 square feet. Your property will now have a super built-up size of 2143 square feet, while your cousin's property will have a super built-up area of 2857 square feet.

​Loading Factor: Meaning 

Now that you have understood what built-up, super built-up, and carpet area means, now is the time to understand the loading factor. In simple terms, a loading factor is a distinction between an apartment's carpeted area and its super built-up area. Additionally, it includes built locations like elevators, lobbies, maintenance rooms, parking lots, parks, and other areas that are not only for you.

If the loading factor is 1.40, the builder may have increased your carpet area by 40%.

How Is The Loading Factor Calculated?

If the carpet area is 1275 square feet and the super built-up area is 1785 square feet, then Super Built-Up Area - Carpet Area = Loading Factor 1785 - 1275 square feet is the loading factor. 510 square feet per loading factor (40 per cent carpet area) Therefore, the loading factor is 40%.
