1. What is Cost Per m² Calculation?

The Cost Per m² calculation is a fundamental metric in construction that helps evaluate the efficiency and cost-effectiveness of building projects by standardizing costs across different project sizes.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• Total Cost — The complete project cost in USD
• Area — The total built area in square meters (m²)

Explanation: This calculation standardizes construction costs regardless of project size, allowing for meaningful comparisons between projects.

3. Importance of Cost Per m²

Details: Cost Per m² is crucial for budgeting, cost estimation, project comparison, and financial planning in construction projects. It helps identify cost outliers and assess value for money.

4. Using the Calculator

Tips: Enter the total project cost in USD and the total built area in m². Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical Cost Per m² for residential construction?
A: This varies widely by location and quality, but typically ranges from $1,000 to $3,000 per m² for standard construction.

Q2: Does Cost Per m² include land costs?
A: Typically no - it usually refers only to construction costs. For total project costs including land, this should be specified.

Q3: How accurate is Cost Per m² for estimating?
A: It provides a rough estimate but doesn't account for design complexity, site conditions, or premium finishes which can significantly affect costs.

Q4: Should I use internal or external area?
A: Standard practice is to use Gross Internal Area (GIA) for residential projects and Gross External Area (GEA) for some commercial projects.

Q5: How does Cost Per m² change with project size?
A: Generally decreases with larger projects due to economies of scale, though this isn't linear and depends on many factors.
