How Much Concrete Do I Need?
Use our simple and intuitive calculator to find out how much ready-mix concrete you will need for your next project. Still not sure? Please call us at 330-227-9614 - we are here to help!
This calculator is provided to assist you in determining the number of concrete yards to order. The calculator gets you within an approximate range of accuracy. Cubic Yards are rounded up in 1 yard increments.
Variations in the grade on the job site are not reflected in calculations. Check with the dispatcher if you want a more precise figure on yardage needed.
Calculating how many cubic yards of concrete to order can be difficult since we usually think in feet and inches and not yards. Also, areas to be filled with concrete are not always perfect rectangles. Often they are irregular shapes with angled sides. Most areas to be filled with concrete can be divided into rectangles, triangles, and pier holes (circles or columns). The drawing at the bottom of this page shows a driveway, walkway, and stepping stone as an example. This calculator provides entries for each of these three main shapes. Each shape needs certain dimensions and a depth. You may enter your dimensions in feet, inches, or both feet and inches.
The calculator computes the volume of each shape and converts it to cubic yards. The calculator provides rows for you to enter the information for each of your shapes. Enter the dimensions in feet, inches, or both. When you select the calculate button, each area will have the cubic yards calculated and the totals for all areas will be shown at the bottom of the form.
Rectangles are defined by width, length, and depth
Triangles are defined by the length of each of the three sides (A, B, C) and depth
Pier Holes (columns or circles) are defined by diameter and depth
Cubic Yards = The number of cubic yards computed for the shape entered
Total Yards = The actual number of yards computed
Add for Error = A percentage to add (default 5%) to the total to allow for computational error and uneven excavation
Adjusted Yards = The Total Yards +computed error adjustment
Yards to Order = Adjusted yards rounded up to next yard (Concrete is sold in whole yards.)
Calculate = Calculates Cubic Yards for each area and totals at the bottom
