A loading percentage between 20% and 30% is generally considered reasonable for most residential projects. The loading percentage is the difference between the carpet area and the super built-up area, representing the share of common spaces such as lifts, corridors, staircases, lobbies, clubhouses and other shared amenities. Projects with a loading of 20% to 25% are usually considered very efficient because buyers get a larger usable carpet area. A loading of 25% to 30% is common in modern residential developments that offer premium amenities. If the loading percentage is above 30%, buyers should carefully evaluate whether the additional facilities justify the extra cost. Before purchasing a property, always compare the RERA carpet area instead of relying only on the super built-up area. This helps you understand the actual living space you will receive and make a better value-for-money decision.
