Concrete Calculator — Cubic Yards & Bags
inches
Tip: Common slab thicknesses: 4″ for driveways/patios, 6″+ for heavy vehicles. 27 cubic feet = 1 cubic yard. 60 lb bag yields ≈ 0.45 cu ft; 80 lb bag ≈ 0.6 cu ft (estimates).

The Concrete Yards Calculator helps users quickly determine how much concrete they need for a project by allowing them to select their preferred units, choose the shape of the slab or column, and enter the required measurements. After selecting a rectangular slab, circular slab, or cylindrical column, users can input dimensions such as length, width, diameter, height, or thickness depending on the shape.

The calculator also provides options to include a waste percentage to account for spillage or uneven ground and allows users to enter the price per cubic yard for a cost estimate. If bagged concrete is preferred, users can select 60 lb or 80 lb bags to see the quantity needed. Once the details are entered, pressing “Calculate” instantly displays the total cubic feet, cubic yards, cubic meters, required bags, and estimated cost. Users can then download a PDF report for record-keeping or project planning and easily reset the form to calculate a new project.
