About the Construction Cost Calculator

Construction cost estimation is the foundation of project budgeting and bidding.

This calculator provides a quick estimate based on area, cost per square foot, and labor/materials split.

Formula

            Total Cost = Area × Cost Per Sq Ft
          
A
— Total Area (sq ft)
C
— Cost per Square Foot
L
— Labor Percentage
M
— Materials Percentage

How to use this calculator

  1. 1

    Enter total area

    The total square footage of the construction project.

  2. 2

    Enter cost per square foot

    The average cost per square foot for similar projects.

  3. 3

    Enter labor percentage

    The percentage of total cost attributed to labor.

  4. 4

    Enter materials percentage

    The percentage of total cost attributed to materials.

Example calculations

Office building construction

A 10,000 sq ft office building with a cost of $200/sq ft, 40% labor, 60% materials.

Total = 10,000 × $200 = $2,000,000. Labor = $800,000. Materials = $1,200,000.

Total construction cost:
$2,000,000
Labor cost:
$800,000
Materials cost:
$1,200,000

The estimated construction cost is $2M with labor representing 40%.

Interpreting your results

Construction costs vary significantly by location, quality, and market conditions.

Labor and materials percentages help with resource planning and procurement.
