What is the Carpet Area?

The area of an apartment that can be covered by a carpet or the net usable area is known as the carpet area. It is the distance between the inner walls. The carpet area would include the areas of the bedroom, living room, kitchen, bathrooms, balconies & staircases within the house/flat. It does not include the external and internal walls, terraces, common areas, lifts, corridors, utility ducts, etc.

How to Calculate Carpet Area

General Carpet Area Calculation

The carpet area can be calculated by a simple formula which is:

Carpet area = (area of bedroom + living room + kitchen + balconies + toilets) – the thickness of the inner walls.

In most cases, the carpet area in your apartment typically comprises between 70% to 90 % of its total built-up area

Let’s take an example of a real apartment carpet area calculation-

Suppose an apartment has a 1392.65 sq. ft. built-up area, and 82.8 % of that is the General Carpet Area.

Then, 82.8% of 1392.65 sq. ft. = 1153.11 is the General Carpet Area.

What is a Built-up Area?

The built-up area is the sum of the carpet area and the area of both the exterior and interior walls, balcony, the exterior staircase, and other liveable areas if any. If there is an exclusive terrace, then that too is included in it. The built-up area comprises around 70-80% of the super built-up area.

How to Calculate Built-up Area?

The built-up area is calculated by adding a Carpet Area or, RERA Carpet Area, Both Interior & Exterior Wall areas, Exclusive Balcony, and Corridor if any.

Built-up Area= Carpet Area + Wall Areas + Terrace and Balcony + Exclusive Corridor

Usually, the Built-up area is 10% to 15% more than the Carpet Area So, if your RERA Carpet Area is 1211 sq. ft., then the built-up area will be between 1332.1 sq. ft. and 1392.65 sq. ft.

Carpet Area Vs Built Up Area

• The difference between Carpet Area and Built-up Area is- As per RERA, the Carpet Area is measured by adding the area of the bedroom, living room, kitchen, Balconies, Toilets, and the thickness of the internal partition walls, while the built-up area is the summation of Carpet Area, External Wall Area, Terrace, or Balcony if any and Exclusive Corridor if any.

• The Built-up Area is always more than the Carpet Area and it excludes common areas such as the lift, security room, lobby, clubhouse, etc.

What is a Super Built-up Area?

Super built-up area is referred to as the ‘saleable area’ and homebuyers are usually charged based on this value. It is the sum of the exclusive built-up area, and common areas including the lift, corridors, staircase, clubhouse, and other amenities.

However, it does not include the area of compound walls, open-to-sky swimming pools, parks, driveways, open sports facilities, inaccessible garden areas, play areas, underground sinks, water tanks, and septic tanks.

The proportionate share of common areas is referred to as the “Loading Factor” and is assigned a percentage that usually ranges from 25% to 60% of the carpet area.

If the loading factor is 50% and your carpet area is 1211 sq. ft., then the super built-up area would be 1816 sq. ft.

How to Calculate Super Built-up Area?

Super built-up area is calculated by adding the built-up area and the proportionate common area.

It can also be calculated by multiplying the carpet and 1 + loading factor.

Built-Up Area Vs Super Built-up Area

A built-up area includes all the area of the carpet, balcony, exclusive corridor, terrace, staircase, etc., as well as the thickness of all walls, while a Super Built-up Area includes an exclusive built-up area plus common areas, such as lifts, common corridors, staircases, a clubhouse, and other amenities, and is also known as a “saleable area“.

However, balcony, outer staircase, terrace, verandah, lift, lobby, and garden areas are featured under super built-up area. These are not featured under carpet area and built-up area.
