Ready-Mix Concrete Calculator
Calculate the ready-mix concrete needed for your project. Understand how dimensions, concrete strength, and waste factor affect your project cost and material requirements.
Step 1: Project Dimensions
Understanding Concrete Volume
Calculate concrete volume by multiplying length × width × thickness. Remember to use consistent units. Most concrete projects require 4-6 inches of thickness for driveways and patios.
Step 2: Concrete Details
About Waste Factor
Waste factor accounts for spillage, over-excavation, and irregularities. Simple projects need 5-10% waste, while complex forms or uneven ground may require 15-20% extra concrete.

Concrete Cost Analysis
Concrete Volume Formula
Volume (cubic yards) = (Length × Width × Thickness) ÷ 27 × (1 + Waste Factor)
The total concrete volume is calculated in cubic yards (standard measurement for ready-mix concrete). Multiply dimensions, divide by 27 to convert to cubic yards, then add waste factor. Total cost includes concrete, delivery, labor, and other materials.
