Carpet vs Built-Up Area Calculator

Convert carpet to built-up and super built-up. See loading factor and effective price per usable sq ft.

Developers in Pune often quote super built-up or saleable area while RERA mandates carpet area disclosure for apartments. The gap between carpet and super built-up (loading) directly changes the effective price per usable square foot you pay.

This calculator converts carpet area to indicative built-up and super built-up using adjustable wall and loading assumptions, and shows how quoting the same ₹/sq ft rate on super built-up inflates total ticket size versus carpet.

Always rely on the carpet area in your agreement and RERA certificate. Use our property glossary for definitions, then validate with your advocate before booking.

Frequently asked questions

What is a normal loading factor in Pune?

Many projects show 25 to 35% loading (super built-up vs carpet). Premium towers sometimes lower; verify in your agreement rather than marketing brochures alone.

Is carpet area the same as usable area?

RERA carpet excludes walls, balconies counted separately per rules, and common areas. It is the standard basis for comparing effective price across projects.

Why does ₹/sq ft on super built-up matter?

If two projects quote the same rate per super built-up but different loading, the buyer with lower loading gets more carpet per rupee. This tool illustrates that gap.
