Super Built-Up Area Percentage

In India, loading ranges between 25% to 35% for most apartments.

Loading Percentage Formula

Loading % = (Super built-up area – Carpet area) / Carpet area × 100

Carpet Area Calculator (How to Calculate Easily)

You can manually calculate using:

Carpet Area = Super Built-up Area × (100 – Loading %) / 100

Example:

  • Super built-up area = 1,200 sq.ft
  • Loading = 30%
Carpet Area = 1200 × 0.70 = 840 sq.ft

Impact on Price : Why This Matters!

A flat priced at ₹70 lakh may differ like this:

  • 1200 sq.ft super area
  • 850 sq.ft carpet area

Actual usable cost:

₹70,00,000 ÷ 850 = ₹8,235/sq.ft (real cost)

Not ₹5,833/sq.ft based on super area.
