Know the difference between Carpet Area, Build-Up Area and Super Built-Up Area
Simply put, the carpet area means the total area of a house that you can cover with a carpet. Essentially, it is the area of the dwelling that is usable by you. The carpet area would exclude the likes of your balconies and terraces, but they will include any internal walls that might be a part of your abode. The carpet area of your home will also include the staircase, provided it is inside the house itself.
Carpet Area = Area of Bedroom(s) + Area of Living Room(s) + Area of the Toilet(s) + Thickness of the Internal Walls
India’s real estate regulator RERA defines the carpet area of a property as the total area of all the rooms (including bedrooms, living rooms, and any other rooms) and toilets including the thickness of the internal walls. If we do a comparison of super area vs carpet area, the carpet area of a property does not include the thickness of external walls of the property, lifts, verandah area, balcony, etc, while the super area includes all of these.
The built-up area of a dwelling is the total space available in a home inclusive of its internal walls and balcony. Built-up area is not to be confused with carpet area as there is one key difference that makes carpet area and built-up area different. The built-up area of a home is the total space available in a dwelling, whereas the carpet area is the total space in a dwelling its inhabitant can use, excluding the area covered by internal walls and balconies, if any.
It is very easy to calculate the built-up area of any property if you already have the carpet area measured. The formula is:
Built-up area = Carpet Area + Area of Balconies + Area of the Open Terrace + Area of the Exclusive Corridor + Thickness of the Exterior Walls.
The super built-up area means the summation of the built-up area of a home and the common areas that the homeowner will have access to within the confines of the building that houses the flat. These common areas are the likes of the corridors, lifts, and staircases in a building. Super built-up area, under no circumstance, is to be confused with built-up or carpet area. The built-up area and the carpet area of a home are things that the owners of a flat have exclusive access to, whereas the other common areas of the society, by definition, are for all of the society members to use.
The super built-up area of a property can easily be calculated if the carpet area and the loading factor of the property are known. The loading factor is the difference between the super built-up area and the carpet area of the property and is usually expressed in percentage. In most cases, the loading factor is 25% to 30% of the carpet area.
For example, let’s assume that the carpet area of a property is 10,000 square feet and the loading factor is 25%. Then the super built-up area can be calculated as:
Super Built-up Area = Carpet Area + Loading Factor
10,000 + 2,500 (25% of 10,000) = 12,500 square feet. This is the super built-up area of the property.
The car parking space which the property owner exclusively owns is not included in the super built-up area or built-up area.
You can also get the carpet area of the property if you have the super built-up area with you. To obtain the carpet area using super built-up area, the formula used is:
Super Built-up Area - Super Built-up Area * Loading Factor/100 = Carpet Area
For example, let’s assume that the super built-up area of a property is 1,200 square feet and the Loading Factor is 30%.
Carpet Area = 1,200 - 1,200*30/100
Carpet Area = 1,200 - 360 = 840
Now that you know what are carpet area, built-up area and super built-up area of a property, the following table would give you a clear picture of what is included and what is excluded from each of the three calculations:

Before you go ahead and purchase a property, it is important for you to find out what is the carpet area, built up area and the super built up area of that particular establishment. You need to do it to figure out if there is going to be enough space there for its future habitants. Once you have done so, and if you have decided on taking a home loan to purchase the property, you can do so on Bajaj Markets. Provided you meet the basic home loan eligibility criteria, a Bajaj Markets lending partner will provide you with a housing loan at affordable home loan interest rates. What’s more, you will get to repay the same over 30 years.
The difference between the carpet area and the super built-up area is called the loading factor of the property. It is usually expressed as a percentage of the carpet area. For example, if the super built-up area of a flat is 1,200 square feet and the carpet area of the flat is 1,000 square feet, then the loading factor is 20%.
As per the RERA’s definition of carpet area, the carpet area of a property is the sum of the areas of the bedroom(s), living room(s), toilets and the thickness of the internal walls.
When we use the term “carpet area”, it usually means the area on which a carpet can be laid, that is, the area of all the rooms and toilets excluding the thickness of walls. However, as per the RERA’s definition, the carpet area also includes the thickness of all the internal walls, while the thickness of all the external walls of the property is excluded.
The carpet area of a property (as per RERA’s definition) is the sum of the total floor area and the thickness of the internal walls.
