# What is Carpet Area vs Built-up Area vs Super Built-up Area?

Know the difference between Carpet Area, Build-Up Area and Super Built-Up Area

## What is Carpet Area

The carpet area of a property, in layman’s language, is the area of the property on which a carpet can be laid. It includes the area contained within the walls of all the bedrooms, living rooms and toilets while excluding the area of balconies, lifts, service shaft area, terrace space or any other space that is not exclusively owned by the property owner. The carpet area also excludes the thickness of the walls. However, as per RERA’s definition of carpet area, the thickness of internal walls is included in the carpet area of the property, while the thickness of the outer walls is excluded from the calculation.

## How to Calculate Carpet Area

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.

Carpet Area = Area of Bedroom(s) + Area of Living Room(s) + Area of the Toilet(s) + Thickness of the Internal Walls

Carpet area does not include the thickness of external walls of the property, lifts, verandah area, balcony, etc. To calculate the carpet area of a property, just add up the areas of all the living rooms, bedrooms and toilets.

## What is Built-up Area

The built-up area of a property refers to the area including the carpet area, area of the balcony, exclusive corridor, terrace, flower beds, etc. and the thickness of all the walls. The built-up area is always more than the carpet area as it is measured from the outer perimeter of wall surfaces.

## 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 total area of the property including common areas like lifts, lobbies, corridors, staircase, clubhouse, and other amenity areas, is called the super built-up area. This is sometimes also referred to as the saleable area of the property. Sellers may or may not charge you for common spaces.

## 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:

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

## FAQs on Carpet Area

• ### ✔️How to calculate the loading factor on the carpet Area?

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%.

• ### ✔️What is the carpet area according to RERA?

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.

• ### ✔️What is the difference between the carpet area and RERA Carpet Area?

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.

• ### ✔️What is the difference between floor area and carpet area?

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.
