Concrete Column Calculator

How It Works

Take the hassle out of math and simplify your concrete planning with our free concrete column calculator. With just 3 easy steps, you can quickly determine the exact amount of concrete required for your project. Whether you have various shapes or need to calculate for multiple columns, our app is equipped to handle it all. Let's start calculating!

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!

Record, Save and Update

And there you have it! Pretty easy, right? Now you can keep track of your concrete projects throughout your entire career. Bookmark this page and you're calculations will be here when you return.

Concrete Column Formula

For those who like to do the math by hand, or are curious as to how it's done, below is the formula used:

The Formula: (Diameter × PI × Height × Height × Quantity) ÷ 4

How to Measure a Column

Measuring a concrete column is surprising simple. It involves measuring the height and diameter of your desired column. As you've likely already seen, you can use our handy column calculator above. If you still want to do it by hand, you can use the steps below. Let's begin!

1. Diameter: Measure the diameter of your column. This is essentially the length of the column from end to end through the middle.
2. Height: Measure the height of the column. This will be how tall you want the column to be.

That's it! Now, you can take those measurements and plug them into the formula above and you'll have your estimations.
