How to calculate construction waste rate
This calculator finds construction waste rate as a percentage — how much of total material or budget is being lost to waste relative to the total.
How the calculation works
Waste rate = (Waste amount ÷ Total amount) × 100.
Example
200 sq ft of wasted material out of 2,000 sq ft total ordered: Waste rate = (200 ÷ 2,000) × 100 = 10%.
