Calculate concrete requirements for construction projects.
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.
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.
1:2:3 ratio (cement:sand:gravel)
1:1.5:2.5 ratio for heavy loads
1:2.5:3.5 ratio for stability
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.
