Concrete Column Calculator

Estimate concrete for round and square columns, pillars, and piers. This concrete column calculator computes volume per column and total project volume for accurate ordering of ready mix or bagged concrete.

Column Volume Formula

Round: pi x radius² x height x count. Square: side x side x height x count

How To Use This Tool

Select column shape: round or square.
Enter diameter (round) or side length (square) in inches.
Set column height and count, then calculate.

Calculate Column Concrete Volume

Enter column dimensions, shape, and count to estimate total concrete volume.

Column Shape Diameter / Side Length (in) Diameter for round, side for square Column Height (ft) Floor to top of column Number of Columns (columns) Total columns in project Waste (%)

Concrete Column Calculator FAQs

Clear answers for common estimation and planning questions.

How do I calculate concrete for a round column?

Use the cylinder formula: pi x radius squared x height. Convert the diameter from inches to feet first, then divide radius by half.

What is a typical concrete column diameter?

Residential columns are commonly 8 to 16 inches in diameter. Commercial and structural columns can be 24 inches or larger.

Can this calculate block-filled columns?

Yes. Use the volume output to estimate the concrete needed to fill block or CMU columns with rebar-reinforced concrete.
