Review the method below for assumptions and conventions.

How to use this tool

  1. Enter column radius, height, number of columns, waste allowance.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Volume = π × radius² × height × count × (1 + waste/100).

A WORKED EXAMPLE

Using column radius = 0.2 m, height = 2.5 m, number of columns = 4, waste allowance = 10 %, the result is 1.38230077 m³. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.

Common questions

Which inputs does this calculation need?

Estimate concrete for identical round columns. Enter column radius in m, height in m, number of columns, waste allowance in %. The filled example is editable and is not a saved personal record.

How should I interpret the result?

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
