The loading factor is the difference between the super-built-up area and the carpet area of the apartment. It represents the portion of the total area allocated to common spaces such as elevators, lobbies, and amenities.
The loading factor is increasing due to the growing demand for lifestyle-rich residential projects with modern, shared facilities. Developers are adding more amenities like gyms, pools, and lounges to cater to buyer expectations, which reduces the actual usable area within individual apartments.
The loading factor inflates the total cost of an apartment because the cost of common amenities is often embedded into the per sq ft rate. This means buyers pay more for shared spaces, even though their private living area is smaller.
Homebuyers should consider the actual usable (carpet) area of the apartment, the quality and utility of the common amenities, and the overall value for their money. Transparent disclosures from developers are crucial to ensure buyers understand what they are paying for.
While most developers now quote prices based on RERA-defined carpet area, the cost of common amenities is often embedded into the per sq ft rate. Buyers should be aware of this and seek clear information about the loading factor from the developer or broker.
