Carpet Area Calculator (RERA)
Carpet Area is defined as the net usable floor area of an apartment, excluding the area covered by the external walls, areas under services shafts, exclusive balcony or verandah areas, and exclusive open terrace areas. However, it includes the area covered by the internal partition walls of the apartment.
Simply put, it is the area where you can literally spread a carpet. Understanding this metric is vital for home buyers to ensure they are paying for actual living space, not just “common areas” or thick walls.
Key Features
- RERA Compliant Calculations: Designed to help you estimate the Net Usable Area as per RERA (Real Estate Regulatory Authority) guidelines.
- Multi-Room Support: Add as many rooms as needed (Living, Bed 1, Kitchen, etc.) with individual dimensions.
- Loading Factor Analysis: Automatically calculates the “Loading Factor” percentage by comparing your total carpet area against the builder’s quoted Super Built-up Area.
- True Price Discovery: Reveals the “Real Cost” per square foot of usable space, helping you compare properties that might have different loading factors.
- Visual Loading Bar: A progress bar visually represents how much “extra” you are paying for common spaces.
How to Use
1. Add Rooms: Use the input rows to enter the Length and Width (in feet) for each room in the apartment (e.g., Living Room: 12×15, Bed 1: 10×12).
2. Add More Rows: Click “+ Add Another Room” to include kitchens, bathrooms, and corridors.
3. Enter Quote Details: Input the “Super Built-up Area” and the “Price per Sq Ft” quoted by the builder/seller.
4. Analyze: The tool instantly calculates the Total Carpet Area, the Loading Factor (%), and the Effective Price per Usable Sq Ft.
Formulas & Calculations
1. Total Carpet Area:
Sum of (Length × Width) for all internal rooms.
2. Loading Factor (%):
Loading (%) = ((Super Built Up Area – Carpet Area) / Carpet Area) × 100
3. Effective (True) Price:
First, find Total Cost = Super Built Up Area × Quoted Rate.
Then, True Price = Total Cost / Carpet Area.
*This shows you what you are actually paying for every square foot of space you can live in.*
Why Use This Calculator?
- Legal Verification: Cross-check the area mentioned in the agreement against the physical dimensions of the rooms.
- Budget Planning: Understand the hidden costs of high loading factors in luxury projects.
- Interior Design: Get an accurate total of floor space for flooring, carpeting, or tiling estimates.
Tips for Home Buyers
- Ignore the “Super” Numbers: Salespeople sell on Super Built-up Area. You live in Carpet Area. Always negotiate based on Carpet Area rates if possible.
- Check Balcony Inclusions: Some developers include balconies in carpet area, while RERA usually treats them separately. Use the “Include Balcony” checkbox if your local norms differ.
- Measure Yourself: If buying a resale property, physically measure the wall-to-wall distance to get the exact carpet area.
Frequently Asked Questions (FAQs)
Is Balcony included in Carpet Area?
Under standard RERA definitions, balconies are NOT included in the carpet area. They are classified as “Exclusive Balcony Areas”. However, some older definitions might include them.
What is a good loading factor?
A loading factor of 15-25% is considered efficient. Anything above 30% means a significant portion of your money is going towards common areas like lobbies and stairs.
Does carpet area include internal walls?
Yes, RERA definitions state that the area covered by internal partition walls IS included in the carpet area. Only external walls are excluded.
Conclusion
The Carpet Area Calculator is your personal auditor for property deals. By revealing the loading factor and true cost per square foot, it empowers you to make transparent, informed financial decisions in the complex real estate market.
