Concrete Calculator
About This Tool
Accurate concrete calculations are essential for construction projects. Our Concrete Calculator helps you determine the exact amount of concrete needed for slabs, footings, driveways, and other projects, preventing costly over-ordering or project delays.
Concrete Basics
Concrete is measured in cubic yards (27 cubic feet). Understanding proper mixing ratios and ordering quantities ensures project success.
Common Applications
- Driveways: 4-6 inches thick, reinforced
- Sidewalks: 4 inches thick minimum
- Foundation slabs: 4-6 inches with vapor barrier
- Footings: Width = 2× wall thickness, depth below frost line
Concrete Types and Costs
Ready-Mix Concrete Prices
- Standard mix: $100-$150 per cubic yard
- High-strength mix: $120-$180 per cubic yard
- Fiber-reinforced: $130-$200 per cubic yard
- Colored concrete: $150-$250 per cubic yard
Planning and Waste Factors
- Add 10% for waste and slight over-excavation
- Consider reinforcement requirements (rebar, wire mesh)
- Plan for proper curing time (28 days for full strength)
- Account for delivery and placement logistics

How to Use
Enter the length, width, and thickness of your concrete pour. The calculator determines cubic yards needed and provides cost estimates. Include reinforcement requirements and waste factors for accurate material planning.
Tips & Tricks
Order concrete early in the morning for best workability. Have all tools and helpers ready before delivery. Consider weather conditions - avoid pouring in extreme temperatures. Grade and compact subbase properly. Use proper curing techniques for maximum strength.
Safety Notes
Concrete is caustic - wear protective clothing, gloves, and eye protection. Ensure proper ventilation when working indoors. Use proper lifting techniques for heavy materials. Have water available for washing skin contact. Follow OSHA guidelines for construction safety.
