Finding your perfect home is no easy task. There are a number of key aspects to look into like price, documentation, Vastu, interior decor requirements, etc. Add in a bunch of technical jargon and you could easily find yourself lost and confused. One such technical aspect of homes that you should be aware of is carpet area and carpet area, calculator. For a layman, words like carpet area, built-up area and super built-up area are foreign words that need explaining.

What is Carpet Area?
The area of the house not including the thickness of the interior walls that a carpet may easily cover is known as the “carpet area.” The area covered would be the actual carpet area if you had to install carpet from wall to wall across your entire home. It is the physical space in your home that you may use.
The carpet area allows you to ascertain the exact amount of floor space that will be available for you to occupy. The areas included under the carpet area are-
- Kitchen
- Bathrooms
- Rooms- bedrooms, living rooms, dining rooms, closets, etc.
- Staircases within the property
- Balconies
- Pantries
The areas that are excluded under the carpet area are-
- Terrace
- Shared spaces or common areas
- Utility ducts
- Interior and exterior walls
Carpet Area Calculator
You can use a carpet area calculator to determine the exact available area of the home you intend to buy. You can see the actual amount of unusable space from the calculated number. As a result, it is measured from wall to wall, which means that the carpet area does not take into account the thickness of the walls. Check the carpet area before purchasing a home because it often accounts for 70% of the total built-up area.

The easiest way to calculate the carpet area is-
Total Area (Bedroom + Living + Balconies + Bathrooms) – Inner Wall Thickness = Carpet Area
Typically, the carpet area makes up approximately 70% or less of the built area. If the built-up space is 2,000 square feet, for instance, your carpet should be about 1400 square feet because carpet accounts for 70% of the entire built-up area. To achieve an accurate measurement, you must physically measure the size of the property from wall to wall.
RERA Carpet Area Calculation
If you’re planning to buy or rent a property in India, it’s essential to understand the concept of RERA carpet area. RERA, or the Real Estate Regulation Act, 2016, mandates that all real estate projects register with the authority and disclose the carpet area of the flats. The RERA carpet area is the actual usable area within the walls of the flat, including the balcony but excluding the walls’ thickness.
Calculating the RERA carpet area of a property can be confusing, but it’s crucial to know to make an informed decision. Here are the steps to calculate the RERA carpet area:
- Check the floor plan of the flat and measure the dimensions of the rooms.
- Deduct the thickness of the walls, which is usually around 6 inches.
- Include the balcony area in the calculation.
- Add up the carpet area of all the rooms to get the total RERA carpet area.
It’s important to note that the RERA carpet area is not the same as the built-up area or the super built-up area. The built-up area includes the carpet area, plus the thickness of the walls and common areas like lifts, staircases, and lobbies. The super built-up area includes the built-up area plus the proportionate area of amenities like gardens, playgrounds, and swimming pools.
How to Calculate the Loading Factor
When it comes to real estate, the loading factor is an important concept that affects the price of a property. The loading factor refers to the additional space added to the carpet area to arrive at the built-up area. The loading factor includes the thickness of the walls, common areas like lifts and lobbies, and other amenities like gardens and playgrounds.

To calculate the loading factor of a property, you need to divide the built-up area by the carpet area and subtract 1. The formula is as follows:
Loading Factor = (Built-up Area / Carpet Area) – 1
For example, if the built-up area of a property is 1,000 square feet, and the carpet area is 700 square feet, the loading factor would be:
Loading Factor = (1000 / 700) – 1
Loading Factor = 0.43
The loading factor is expressed as a percentage, and a lower loading factor indicates that the property has a higher carpet area compared to the built-up area.
What is a Built-Up Area?
The space that is completely enclosed by internal and external walls, as well as by ducts and the interior, is referred to as the built-up area. It is sometimes referred to as the apartment’s total covered area and comprises the terrace, balcony, and other habitable areas in addition to the carpeted area and the area protected by the thickness of the walls. Areas that are considered under built-up area are-

- Utility ducts
- Carpet area
- Interior and exterior walls
Another popular term used in similar contexts is plinth or covered area. However, when looking at the plinth area only structures present directly under the roof are considered. Structures such as balconies are usually constructed on top of cantilevers which have no direct connection to the roof and hence are not counted under the plinth area. These balconies will be considered under the built-up area.
Built-Up Area Calculation
Built-up area calculation is fairly straightforward. It is-
Carpet area + Area of interior and exterior walls + area covered by utility ducts= Built Up Area
Usually, the built-up area is larger than the carpet area by about 10%. For example, a property with a carpet area of 1500 sq. ft would have a built-up area of about 1650 sq. ft.
What is Super Built-Up Area?
Super built-up Area is the combined total of a property’s built-up area and all of its proportionally sized common areas. For example, if a common area of 4000 square feet is shared amongst 20 homes, then the proportionate common area for each home would be 200 square feet.
Elevators, swimming pools, gardens, lobbies, and other amenities may be found in highly developed areas. Parking, however, is not included and is charged individually.

Areas included in the super built-up area are-
- Built-up area
- Common amenities like clubhouse, swimming pools, elevators, lobby, etc.
Areas that are excluded are-
- Parking structures
- Rooftops
- Gardens, parks, driveways, etc.
Super Built-Up Area Calculation
Built-up Area + Proportionate Common Area = Super Built-Up Area.
Here is a quick formula to compute the Common area if you don’t know its size:
By adding the loading factor to the carpet area, you may determine the super built-up area by asking the builder about the loading factor. Depending on the location of the house and the builder, the loading factor can range from 15 to 50%.
Say for a home with a carpet area of 1000 square feet and a loading factor of 0.35 the super built-up area would be-
Super Built-Up Area= Carpet area (1+ loading factor)
Which would be:
Super built-up area= 1000 (1+0.35) square feet

Why You Should Know About the Loading Factor
Understanding the loading factor is crucial when investing in real estate in India. Here are a few reasons why:
- Pricing: The loading factor affects the price of the property. A lower loading factor means a higher carpet area, and hence, a higher price per square foot.
- Transparency: The Real Estate Regulation Act, 2016, mandates that builders disclose the loading factor of a property. Knowing the loading factor can help you verify if the builder has disclosed accurate information.
- Space: The loading factor affects the usable space within the property. A higher loading factor means less usable space, while a lower loading factor means more usable space.
What is the Difference Between the RERA Carpet and Carpet Area?
The terms RERA carpet area and carpet area are often used interchangeably in the real estate sector, but they are not the same. The RERA carpet area is the net usable floor area of an apartment, excluding external walls, balconies, and utility areas. It is the area that you can actually use and is calculated using specific formulas laid down by RERA.
On the other hand, the carpet area includes the entire area within the walls of an apartment, including the thickness of the walls. It is the actual area that you can carpet, and it is also known as the net floor area.
The difference between the RERA carpet area and the carpet area is significant, as it affects the cost and value of the property. The price of an apartment is usually calculated based on the RERA carpet area, and the loading factor or the built-up area. The loading factor refers to the proportion of the common area that each apartment owner has to share.

The difference between an apartment’s super built-up and carpeted areas is known as the loading factor. Homebuyers need to be aware that a developer uses loading to recoup the cost of the amenities he provides, such as the lobby, maintenance room, elevators, parking, and terrace.
5. What is a cantilever?
A beam that is only supported at one end and has the load carried over the overhang is known as a cantilever. In contrast, a beam that is merely supported has support at both ends.
Cantilevers eliminate the need for bracing or supporting columns by creating an open area beneath the beam.
With the development of reinforced concrete and steel, cantilevers became a common structural type. They are widely used in construction, particularly in cantilever bridges.
