Construction Cost per m² Calculator
Estimate construction cost per square meter. Instantly calculate total build cost from area, quality level, floors, soft costs, and contingency.
How It Works
Estimates the total budget for a construction project by adding hard costs (materials, labor), soft costs (permits, design), and contingencies.
Formula
Total Cost = Hard Costs + Soft Costs + Contingency
Cost per Sq Ft = Total Cost / Total Square Footage
Contingency is a buffer (usually 10-20%) added to the total to account for unexpected overruns.
Worked Example
Building a 2,000 sq ft Home
- Base Construction (Hard Cost): 2,000 sq ft × $150/sq ft = $300,000
- Soft Costs (Permits, Arch): $30,000
- Subtotal: $330,000
- Contingency (10%): $33,000
- Total Cost: $363,000
- Final Cost per Sq Ft: $181.50
Common Mistakes
✕
Forgetting soft costs
✓
Permits, architectural fees, and utility connections can add 10-20% to your total budget.
✕
Setting contingency too low
✓
Always allocate at least 10% (ideally 15-20% for remodels) for unexpected issues.
