How It Works

Streamline your concrete project with our free concrete circle & tube calculator. In just 3 simple steps, find the precise concrete quantity required for your circular or tubular structures. No matter the varying dimensions or number of circles and tubes, our calculator is designed to make the process seamless. Let's start calculating for your concrete circles and tubes with ease!

3 Easy Steps

1. Choose your settings. Select your unit type, cost type (by bag or by the yard/meter), bag size, cost and desired waste amount. Your settings will be automatically saved for when you come back the next time.
2. Choose your shape(s). We understand that many projects require multiple shapes or dimensions. Choose from a slab, footing, column, stairs, curb/gutter, circle/tube or any combination of them—it doesn't matter how many you have, we'll do the heavy lifting.
3. Add your dimensions. Once your shapes are added, input the dimensions that you've measured for each of them. After that, your results will be shown!
