Formula Used

The total construction cost is calculated using the following formula:

Total Cost = (Base Cost per Square Foot × Square Footage) + (Labor Cost per Square Foot × Square Footage) + (Material Cost Factor × Base Cost) + (Permit and Fees)

Where:

Base Cost per Square Foot varies by building style and quality level
Labor Cost per Square Foot is adjusted for different Ontario regions
Material Cost Factor accounts for premium materials
Permit and Fees are estimated based on Ontario building codes

Note: This calculator provides an estimate. Actual costs may vary based on site conditions, unexpected challenges, and changes in material prices.

Base cost: $220/sq ft × 1,500 = $330,000
Labor cost: $120/sq ft × 1,500 = $180,000
Premium materials: +12% → $50,400
