What is Carpet 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.

How to Calculate Carpet Area?

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.

What is Built-up Area?

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.

How to Calculate Built-up Area?

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.

What is a Super Built-up Area?

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.

How to Calculate Super Built-up Area?

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
