Rate Analysis & Guidance

ℹ️ Additional Cost Impact: Purchase charges add +₹ 625 / sq.ft (+6.67%) over the basic quoted rate of ₹ 9,375 / sq.ft.
ℹ️ Carpet Area Loading: Usable carpet efficiency is 75.0% (33.33% loading). For every 100 sq.ft of saleable area, 75 sq.ft is usable floor space.

tips_and_updates

Always Compare Properties Like-for-Like: Never compare a property quoted at ₹8,000/sq.ft on saleable area directly with another quoted at ₹11,000/sq.ft on carpet area. Always convert both properties to effective carpet-equivalent rates before deciding which is more economical.

This calculator provides mathematical estimates based on the property price, area and costs entered. Area definitions such as carpet, built-up and saleable/super built-up area can vary by project and documentation. Verify the area and cost components from the property's official cost sheet and documents before comparing or making a purchase decision. This calculator is for informational purposes only.

Why Cost per Sq. Ft. Can Be Misleading

A property's quoted price per sq. ft. is meaningful only when you know which area definition is being used and which additional costs are included. Comparing properties on mismatched area bases creates a false sense of value.

Concept 1

Basic Quoted Rate

Quoted property price divided by super built-up saleable area. Excludes taxes, stamp duty, and builder charges.

Concept 2

Effective All-In Rate

Total acquisition cost (property price + taxes + deposits + fees) divided by saleable area.

Concept 3

Carpet-Equivalent Rate

Total acquisition cost divided strictly by net usable carpet area. Excludes non-usable loading.

Concept 4

Loading Percentage

The proportion of common area (lobbies, corridors, staircases) added to carpet area to arrive at saleable area.

Before Comparing Properties Checklist

✓ Is the quoted rate based on carpet area or super built-up saleable area?
✓ What is the exact carpet area mentioned in the RERA carpet area certificate?
✓ What is the loading percentage ((Saleable - Carpet) / Carpet)?
✓ Are stamp duty (~5%), registration (1%), and GST (5%) included in the quoted figure?
✓ Are parking, clubhouse, maintenance deposits, and legal fees added to the total cost?

Frequently Asked Questions

What is the difference between Basic Price per sq. ft. and Effective Price per sq. ft.?

Basic Price per sq. ft. is quoted property price divided by area. Effective Price per sq. ft. includes all additional acquisition costs (stamp duty, registration, GST, legal fees, builder charges) divided by area.

Why is Carpet-Equivalent Price per sq. ft. higher than Saleable Price per sq. ft.?

Carpet area represents usable net floor space, which is smaller than saleable (super built-up) area due to common area loading. Dividing total cost by a smaller carpet area yields a higher price per sq. ft.

How is loading percentage calculated?

Loading percentage is calculated as ((Saleable Area - Carpet Area) / Carpet Area) * 100.
