Free Online Concrete Calculator: Estimate Volume & Material Costs

Calculate Your Concrete Project Needs

Add a percentage for waste, spillage, and uneven subgrades (e.g., 10-15%).

Accurately calculate the exact concrete volume in cubic yards or cubic meters required for your construction project. Our Concrete Calculator helps you determine material needs for slabs, footings, and columns, preventing costly over-ordering or frustrating shortages. Get instant estimates for bags of concrete mix needed and budget effectively.

Formula:

The fundamental formula for calculating concrete volume is based on the shape of your pour:

  • For Rectangular Slabs / Footings: Volume = Length × Width × Thickness
  • For Round Columns / Piers: Volume = π × (Radius)2 × Height

Units must be consistent; typically, results are converted to cubic yards for ordering.
