Cubic Yards Concrete Calculator
Calculate the cubic yards of concrete needed for your project. Determine concrete volume for slabs, footings, walls, columns, and other concrete structures.
Step 1: Project Dimensions
Common Thickness Reference
4 inches = 0.33 ft • 5 inches = 0.42 ft • 6 inches = 0.5 ft • 8 inches = 0.67 ft • 10 inches = 0.83 ft • 12 inches = 1 ft
Step 2: Options & Quantity
About Waste Factor
A 10% waste factor is recommended for most projects to account for spillage, over-excavation, and variations in subgrade. For complex projects, consider 15-20%.

Volume Calculation Breakdown
Cubic Yards Formula
Cubic Yards = (Length × Width × Depth) ÷ 27
First calculate cubic feet: Length (ft) × Width (ft) × Depth (ft). Then divide by 27 to convert to cubic yards (1 cubic yard = 27 cubic feet). Add waste factor percentage.
