How to use this calculator

Calculate component volumes from a target soil volume and percentage mix.

How the calculation works

  • Enter the project dimensions or quantities.
  • Choose the unit and optional waste factor where relevant.
  • Review the rounded material estimate and supporting details.

Formula

Component volume = target volume x component percentage.

Example

A 100 cu ft mix at 40%, 30%, and 30% needs 40, 30, and 30 cu ft of each component.

Understanding your result

Use the output as a practical starting point, then review it before using it in an important workflow.

Assumptions and limitations

  • This is ratio math only, not horticultural advice.
  • Percentages should add to 100% for a complete mix.
