Loading factor (also called the loading percentage) represents the difference between carpet area and super built-up area, expressed as a percentage. It accounts for the proportionate share of common areas (lobbies, staircases, lifts, amenity spaces) allocated to each apartment unit.
Loading Factor = ((Super Built-Up Area - Carpet Area) / Carpet Area) × 100
Typical loading factors in Indian real estate: - Budget projects: 20-25% - Mid-range projects: 25-30% - Premium/luxury projects: 30-40% (more amenities = higher loading) - Ultra-luxury projects: 35-45%
Example: If an apartment has 1,000 sq.ft. carpet area and 1,350 sq.ft. super built-up area, the loading factor is 35%.
A lower loading factor means you get more usable space per rupee spent. However, a higher loading factor is not necessarily bad — it could mean the project has better amenities, wider corridors, and more spacious common areas that improve your living experience.
When comparing two projects, always compare carpet areas (not super built-up areas) for an apples-to-apples comparison of actual livable space.
