Construction Waste Calculator
Calculate construction waste volume, weight, and disposal costs for your building project. Estimate debris from demolition, renovation, and new construction.
Step 1: Project Specifications
Understanding Waste Factors
Waste factor accounts for material loss, cuts, breakage, and unusable scraps. New construction typically has 5-10% waste, while demolition projects can reach 20-30%.
Step 2: Material Parameters
About Construction Waste
Construction waste density varies by material. Wood weighs 400-600 lbs per cubic yard, concrete 2,000-2,500 lbs, while mixed debris averages 500-800 lbs per cubic yard.

Waste Material Breakdown
Waste Calculation Formula
Total Waste (tons) = (Project Area × Waste Factor × Material Density) / 2,000
To calculate waste: Multiply project area by waste factor (as decimal), then multiply by material density (lbs per sq ft), and divide by 2,000 to convert to tons.
