Construction Cost Per Square Foot Calculator
Deconstruct construction costs into hard vs soft costs, convert between sq ft and sq meters, and compare against national benchmarks.
Calculation Results
Cost Per Unit Area Formula
Cost Per Sq Ft = Total Construction Budget / Total Square Footage | Cost Per Sq M = Cost Per Sq Ft × 10.7639- Hard Costs (approx. 80%): Concrete, framing lumber, roofing, windows, mechanical systems, and trade labor.
- Soft Costs (approx. 20%): Architectural blueprints, civil engineering, zoning permits, legal fees, and loan interest.
- Metric Conversion: 1 square meter = 10.7639 square feet.
Step-by-Step Worked Example
Scenario: Evaluating a $420,000 construction bid for a 2,100 sq ft residential building
Calculation Steps:
- Cost Per Square Foot = $420,000 / 2,100 sq ft = $200.00 / sq ft
- Hard Costs (80%) = $200.00 × 0.80 = $160.00 / sq ft
- Soft Costs (20%) = $200.00 × 0.20 = $40.00 / sq ft
- Cost Per Square Meter = $200.00 × 10.7639 = $2,152.78 / sq m
Result: The project rate is $200.00/sq ft ($2,152.78/sq m), falling into the Upgraded / Custom Finishes tier.

Frequently Asked Questions
What is considered a normal hard vs soft cost ratio?
In residential and light commercial construction, direct hard construction costs represent 75% to 82% of the budget, while soft costs (design, permits, financing, insurance) account for 18% to 25%.
