What Is Construction Cost per Square Foot?
The construction cost per square foot is a fundamental metric used in the building industry to estimate and compare project costs. Here’s the simple formula:
Cost per sq ft = Total construction cost ÷ Total built-up area in sq ft
This calculation helps you:
- Compare different construction projects
- Plan your financing accurately
- Forecast total expenditures
- Make informed decisions about materials and finishes
Step-by-Step Guide: How to Calculate Cost of Construction per Sq Ft
Step 1: Calculate Your Total Construction Cost
To accurately determine how to calculate cost of construction per sq ft, you first need to account for all expenses:
Materials (50-60% of total cost):
- Cement and concrete
- Steel and reinforcement bars
- Bricks and blocks
- Tiles and flooring materials
- Paint and finishes
Labor Costs (30-40% of total cost):
- Masonry work
- Plumbing installation
- Electrical work
- Carpentry and interior work
Professional Fees:
- Architectural design: ₹25-500 per sq ft
- Structural design: ₹5-200 per sq ft
- Project management fees
Additional Expenses:
- Building permits and approvals
- Site surveys and soil testing
- Transportation and logistics
- Contractor’s profit and overhead (10-20%)
- Contingency fund: Always add 10-15% extra
Step 2: Determine Your Total Built-up Area
Built-up area includes:
- Usable floor space (carpet area)
- Wall thickness
- Columns and beams
- Passages and corridors
- Balconies and terraces
- Parking areas (if covered)
Important Note: Always use built-up area, not carpet area, when calculating construction cost per sq ft. Built-up area is typically 15-20% more than carpet area.
Step 3: Apply the Construction Cost Formula
Once you have both figures, apply this formula:
Cost per sq ft = Total Construction Cost (₹) ÷ Built-up Area (sq ft)Example Calculation:
- Total construction cost: ₹30,00,000
- Built-up area: 1,500 sq ft
- Result: ₹30,00,000 ÷ 1,500 = ₹2,000 per sq ft
