When this tool is useful
Practical preliminary checks
- Comparing broad construction budgets for differently sized homes
- Checking whether two estimates are being compared on the same area basis
- Translating cost-per-square figures into cost per m²
- Creating an early feasibility benchmark before detailed pricing
How it works
The calculator divides the entered project cost by the entered floor area. It also converts the area to building squares so the same project can be compared using both common residential building measures.
Important estimating note
Cost per m² is a broad benchmarking tool, not a quotation method. Site conditions, structural work, access, specification, services, finishes, demolition and project complexity can materially change the final cost.
Frequently asked questions
How do I calculate building cost per square metre?
Divide the total project cost by the floor area in square metres. Make sure the cost and area cover the same project scope before comparing the result with another project.
Is cost per m² an accurate way to price a building project?
It is useful for broad feasibility and comparison, but it is not a substitute for project-specific estimating because the specification, structure, site and scope can vary substantially.
Should I compare builder quotes only by cost per m²?
No. Compare the drawings, inclusions, exclusions, allowances, site costs, contract terms and specification as well as the headline rate.
