Concrete Column Calculator
Switch between round (post holes, sonotube piers) and square/rectangular columns, then enter height to get the volume for one column — use "Add to job list" if you're pouring several. Pouring fence posts? Try the Fence Post Concrete Calculator.

Pouring more than one column? Give this one a label and add it — the results panel keeps a running grand total.
FAQ
- Is a fence post footing the same as a column?
- Yes — for a round post hole, pick Round and enter the hole diameter and depth as height. Sonotube forms are usually sold by diameter, matching this calculator directly.
- Should I subtract the post itself from the volume?
- This calculator gives the full hole volume. If a large post or pier will displace a meaningful amount of concrete, subtract its own volume from the result.
