Calculate concrete requirements for construction projects.

About Concrete Calculator

Our concrete calculator helps you determine the exact amount of concrete needed for your construction projects. Whether you're building a foundation, patio, driveway, or any concrete structure, this tool provides accurate volume calculations and material requirements.

What It Calculates

  • Volume: Concrete needed in cubic yards
  • Weight: Total weight of concrete required
  • Bag Count: Number of 80-pound concrete bags needed
  • Dimensions: Length, width, and depth calculations

Common Concrete Projects

Residential Projects
  • Driveways and walkways
  • Patios and decks
  • Foundation slabs
  • Retaining walls
  • Garden borders
Commercial Projects
  • Parking lots
  • Warehouse floors
  • Industrial foundations
  • Road construction
  • Bridge supports

How to Use

Enter the length, width, and height/depth of your concrete project in feet. The calculator will automatically compute the volume in cubic yards, total weight in pounds, and the number of 80-pound concrete bags you'll need.

Concrete Mix Information

Standard Mix

1:2:3 ratio (cement:sand:gravel)

High Strength

1:1.5:2.5 ratio for heavy loads

Foundation Mix

1:2.5:3.5 ratio for stability

Pro Tip

Always order 10-15% more concrete than calculated to account for spillage, uneven surfaces, and formwork. Consider weather conditions and curing time when planning your concrete project.
