Estimate cubic yards needed
This calculator estimates the volume of concrete needed for common construction projects like slabs, footers, and columns.
Cubic Yards: Concrete is typically sold by the cubic yard. One cubic yard equals 27 cubic feet.
Order Extra: Always order 5-10% more than calculated to account for spillage, uneven ground, and mistakes.
Bag Estimate: For small jobs, the calculator also shows approximately how many 80-pound bags you'd need. One 80-lb bag makes about 0.6 cubic feet of concrete.
How to use: Select your project type, enter the dimensions, and get an instant estimate of concrete needed in cubic yards and bags.
