Excavation Volume Calculator

Calculate the bank volume of a rectangular excavation and the loose volume after a swell factor you enter.

Length (m)Width (m)Depth (m)NumberSwell factorLoose volume ÷ bank volume. 1.25 means the spoil is 25% larger than the hole.

How this number is worked out

Bank volume is length × width × depth × number of holes. Loose volume is bank volume × the swell factor you enter. This is a planning estimate. Confirm quantities against the structural drawings before ordering or cutting material.
