How to calculate concrete waste
This calculator applies a waste percentage to a base concrete quantity to account for spillage, over-excavation, and minor form issues.
How the calculation works
Total with waste = Base quantity × (1 + Waste percentage ÷ 100).
Example
A calculated base volume of 10 cubic yards with a 10% waste allowance: Total = 10 × 1.10 = 11 cubic yards.

Pro Tips for Concrete Waste
- 5-10% is a typical waste allowance for straightforward pours; uneven ground or complex forms may warrant more.
- Round your final order up to the nearest half or full cubic yard, since suppliers typically don't sell in smaller increments.
Common Concrete Waste Mistakes to Avoid
- Ordering the exact calculated volume with zero waste allowance, which frequently results in running short mid-pour.
