Page guide

Work out bin capacity and split the material you need to add using your own volume recipe.

How to use Compost volume calculator
  1. Enter your measured quantities, units and assumptions.
  2. Review the calculated result and the stated limits.
  3. Download the report or plan for your project.

Useful next steps

Measure the usable space

Choose rectangular or cylindrical bins, measure the inside and enter the number of identical bins. Target fill and existing material apply to their combined capacity.

Build a volume recipe

Enter material names with relative volume parts. The example 2:1 mix is editable and is not a carbon-to-nitrogen recommendation. The retained-volume percentage converts the remaining settled space to loose additions.

Save the measurements and assumptions

Download CSV and a text or JSON report. The calculation runs on your device. Changing a unit keeps the number you entered, so check both before using the result.
