Carpet area of apartments in real estate in Hyderabad dips to 62 pc What is the loading factor? In residential apartments, the average loading factor is the difference between the super-built-up area and carpet area. Loading percent = (Super Built-up Area – Carpet Area) ÷ Carpet Area × 100 While RERA now requires developers to mention the total carpet area provided to homebuyers, no law currently limits the loading factor in projects.
