Page guide

Calculate soil fill after subtracting layers and existing material, then estimate whole bags of loose soil.

How to use Raised bed soil 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 bed

Use internal dimensions. Subtract the drainage and structural depths you actually have from every bed. Those fields describe space occupied; they do not recommend installing a particular layer.

Allow for existing soil and settling

Enter existing settled soil across all beds. Divide the remaining settled volume by your measured retained-volume fraction to estimate loose material, then round up to whole bags.

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.
