Calculate your actual usable space from builder area claims
Typically 20-30% for apartments, up to 35% for complexes
Carpet Area
Common Area
Super Built-up
Carpet area is your actual usable space in an apartment, including bedrooms, living areas, kitchen, and bathrooms but excluding walls and common areas. Builders often advertise super built-up area instead, which includes carpetarea plus walls, corridors, lobbies, and shared amenities. The loading factor (20-30%) represents the percentage of common areas included in the super built-up measurement. Understanding this distinction is crucial because builders inflate areas by using super built-up figures, making properties appear larger and more valuable than they actually are. Under RERA regulations, developers must disclose carpet area alongside super built-up area, but many marketing materials emphasize the larger figure. Carpet area determines your actual living space and should be the basis for property valuation and price comparisons. This calculator converts builder-quoted super built-up areas to actual carpet area using loading factors, helping you understand what you're actually paying for.
