AI explanation
Formula
Net volume = cut volume − fill volume (positive = surplus to export, negative = shortfall to import)Worked example
150 m³ cut, 100 m³ fill
| Field | Value |
|---|---|
| Cut (excavated) volume (m³) | 150 |
| Fill (needed) volume (m³) | 100 |
| Net volume | 50 |
| Site balance | Net cut — export 50 m³ of surplus soil |
Assumptions
- Uses bank (in-situ) volumes for both cut and fill — if you're working from a loosened/ swelled excavation volume, convert back to bank volume first (divide by the swell factor used in the Excavation Calculator, typically ~1.25) for a consistent comparison.
Frequently asked questions
What does a positive net volume mean?
A positive result means you have more soil from excavation (cut) than you need for filling elsewhere on site — that surplus needs to be hauled away (exported).
What does a negative net volume mean?
A negative result means you need more fill material than your excavation provides — you'll need to import additional soil.
How do I get my cut and fill volumes in the first place?
Use the Excavation Calculator for cut volume, or calculate fill volume the same way (length × width × depth) for the area(s) that need filling.
