Concrete Calculator
Calculate concrete volume, materials, and cost for slabs, footings, columns, and more. Perfect for contractors, DIYers, and construction professionals.
Tips for Using the Concrete Calculator:
- • Enter dimensions in feet and inches as specified for each measurement
- • Include a waste factor of 5-10% for most projects (10-15% for complex shapes)
- • For slabs, include the depth of any thickened edges in your calculations
- • Remember that different projects may require different concrete mix designs
- • For larger projects, consider ordering slightly more concrete than calculated

- Material Budgeting: Create accurate estimates for project budgeting
Understanding Concrete Mixtures:
Concrete is typically made from a mixture of cement, sand, gravel, and water. The standard mix ratio is often 1:2:3 (cement:sand:gravel), though this can vary based on the application and required strength. Our calculator provides material estimates based on this standard ratio.
For specialized applications like high-strength concrete, decorative concrete, or projects with specific performance requirements, consult with a concrete supplier or structural engineer for custom mix designs.
Remember to consider reinforcement materials like rebar or wire mesh, which are often required but not included in basic volume calculations. For accurate cost estimates, factor in delivery fees, labor costs, and equipment rental if needed.
