About the Earthwork Calculator

Cut and fill volumes for levelling a site, with the net import or export of material.

Also known as: cut and fill calculator, site levelling, earth moving volume, grading calculator.

How to use this calculator

  1. Enter site area, average cut depth, average fill depth, fill compaction allowance and the other fields.
  2. The result updates instantly as you type — press Calculate (or Enter) at any time.
  3. Review the breakdown shown under the main result.

Formula

net = cut volume − compacted fill volume

Worked example

Using the values pre-filled in the calculator above:

  • Site area = 500 m²
  • Average cut depth = 0.3 m
  • Average fill depth = 0.15 m
  • Fill compaction allowance = 20 %
  • Cut bulking factor = 25 %

the calculator returns:

  • Surplus to export: 60 m³
  • Cut volume: 150 m³
  • Fill volume required: 90 m³
  • Bulked export volume: 75 m³
