How to calculate excavation swell volume
This calculator applies a swell percentage to a bank volume to find the resulting loose (swelled) excavation volume — the same core relationship used broadly in earthwork planning.
How the calculation works
Swell volume = Bank volume × (1 + Swell percentage ÷ 100).
Example
80 cubic yards bank volume with a 30% swell factor: Swell volume = 80 × 1.30 = 104 cubic yards.
Frequently asked questions

Pro Tips for Excavation Swell Volume
- Confirm the swell factor for your specific soil type rather than assuming a generic figure, since it varies significantly between soil, clay, and rock.
- Loose (swelled) volume, not bank volume, is what determines truck loads needed for hauling excavated material off-site.
Common Excavation Swell Volume Mistakes to Avoid
- Confusing bank volume and swell volume when ordering trucks or estimating spoil disposal costs, since using the wrong figure under- or overstates hauling needs.
