Concrete Yardage Calculator
Calculate concrete volume in cubic yards for slabs, walls, footings, columns, and more. Estimate how much concrete you need for your construction project.
Step 1: Select Concrete Structure
Understanding Concrete Yardage
Cubic yards measure concrete volume. 1 cubic yard = 27 cubic feet = 46,656 cubic inches. Concrete is typically ordered in cubic yards from ready-mix suppliers.
Step 2: Calculation Options
Concrete Volume Formulas
Slab: Volume = Length × Width × Thickness
Wall: Volume = Length × Height × Thickness
Footing: Volume = Length × Width × Depth
Column (Cylinder): Volume = π × Radius² × Height
Steps: Volume = Step Width × Step Rise × Step Run × Number of Steps

Concrete Volume Calculation Formulas
Rectangular Slab
Formula: Volume = Length × Width × Thickness
Example: 10 ft × 8 ft × 0.5 ft = 40 ft³ = 1.48 yd³
Concrete Wall
Formula: Volume = Length × Height × Thickness
Example: 20 ft × 8 ft × 0.67 ft = 107.2 ft³ = 3.97 yd³
Column (Cylinder)
Formula: Volume = π × Radius² × Height (π ≈ 3.14159)
Example: Radius = 0.75 ft, Height = 10 ft → Volume = 3.14159 × 0.75² × 10 = 17.67 ft³ = 0.65 yd³
Concrete Steps
Formula: Volume = Step Width × Step Rise × Step Run × Number of Steps
Example: 3 ft × 0.67 ft × 1 ft × 3 steps = 6.03 ft³ = 0.22 yd³
