Carpet vs Built-up vs Super Built-up
Builders advertise the super built-up area, but under RERA you buy the carpet area — the space you can actually use. Enter the advertised area and the loading factor to see what you really get, and the true price per usable foot.
Typical 25-40%. The higher the loading, the less carpet you get.
Efficiency 77% — you use 77% of what you pay for.
Indicative only. Loading and wall factors vary by project and are not standardised. Under RERA the builder must sell and register on carpet area, and the sale agreement carries the legally-binding figure — always verify the carpet area in the RERA registration and the agreement before you buy.
