1. What is RERA Carpet Area?

The RERA (Real Estate Regulation and Development Act) defines carpet area as the net usable floor area of an apartment, excluding the area covered by external walls, areas under services shafts, exclusive balcony or verandah area and exclusive open terrace area. It typically represents about 80% of the built-up area.

2. How Does the Calculator Work?

The calculator uses the standard RERA formula:

Where:

• Built-up Area — Total area including walls and common spaces (in square feet)
• 0.8 — Standard conversion factor (80% of built-up area)

Explanation: This calculation provides an estimate of the actual usable space within a property according to RERA guidelines.

3. Importance of Carpet Area Calculation

Details: Knowing the carpet area helps home buyers understand the actual usable space they're paying for, compare properties accurately, and make informed purchasing decisions.

4. Using the Calculator

Tips: Enter the built-up area in square feet. The value must be greater than 0. The calculator will estimate the carpet area based on RERA standards.
