Concrete Volume Calculator
Calculate concrete volume for construction projects. Professional calculator for determining concrete requirements with real-time calculations and cost estimates.
Concrete Volume Formula
The volume of concrete is calculated using:
Where:
- V: Volume of concrete (cubic yards or cubic feet)
- L: Length of the concrete structure
- W: Width of the concrete structure
- H: Height/Thickness of the concrete structure

- Always round up to nearest 1/4 yard when ordering concrete
- Consider extra material for waste and spillage
- Plan for efficient pouring to minimize waste
- Check with suppliers for minimum order quantities
Q&A
Q: How much waste should I account for when ordering concrete?
A: The amount of waste to account for depends on the project type:
Typical Waste Factors:
- Simple Slabs: 5-10% (for spillage and cleanup)
- Complex Footings: 10-15% (due to irregular shapes)
- Foundations: 10-20% (for over-excavation and irregular surfaces)
- Curbs and Gutters: 15-25% (for cutting and finishing waste)
Additional Considerations:
- Uneven subgrade may require additional material
- Formwork settling could require more concrete
- Equipment washout requires additional volume
- Small projects typically have higher waste percentages
Always consult with your concrete supplier for project-specific recommendations.
Q: What's the difference between cubic yards and cubic feet?
A: Cubic yards and cubic feet are both measures of volume:
Conversions:
- 1 cubic yard = 27 cubic feet
- 1 cubic foot = 0.037 cubic yards
- 1 cubic yard = 46,656 cubic inches
Industry Standards:
- Concrete is typically sold by the cubic yard in the US
- Smaller projects might be measured in cubic feet
- Calculations are easier in feet, but orders in yards
Example: A 10' x 10' x 4" slab = 33.33 cubic feet = 1.23 cubic yards.
Always double-check conversions to avoid costly mistakes!
