How to Calculate Construction Cost per Square Foot?
Basic Calculation Formula
Total Construction Cost ÷ Total Square Footage
= Cost per Square Foot
Step-by-Step Process
Step 1: Determine Your Project Scope
You must start by establishing your building class. Then, calculate the total floor area through architectural design.
Step 2: Measure Total Square Footage
- Calculate the gross square footage
- Also include unusable space
- Include all interior and exterior areas
Step 3: Break Down All Construction Costs
Comprehensive cost calculation should include:
Hard Costs:
- Foundation and excavation
- Framing and structure
- Roofing and exterior
- Interior finishes
- MEP systems
- Landscaping
- site work
Soft Costs
- Architectural fees
- Building permits
- Legal fees
- Construction loan interest
- Project management fees
Step 4: Factor in Location-Specific Variables
Building costs depend on labor costs, with a 2% to 6% difference between urban and suburban areas. Consider:
- Local labor rates
- Material availability and transportation costs
- Local building codes and regulations
- Site conditions and accessibility
Step 5: Apply the Formula
You need to sum hard and soft costs and then divide by total square footage for your final per-square-foot cost.
However, by relying on a reliable construction takeoff company, you can easily get the desired results and save your budget.
