How to use it
- Choose rectangular or trench label.
- Enter length, width and depth in meters.
- Optionally enter a bulking percentage and calculate.
Excavation Volume Calculator
Calculate a simple rectangular geometric volume and optional bulking adjustment.
Important: This calculator is an educational estimate only.

About the Excavation Volume Calculator
This page applies a rectangular volume formula to entered dimensions and optionally scales the result by a user-entered bulking factor.
Formula
Geometric volume = length × width × depth. Adjusted volume = geometric volume × (1 + bulking percent ÷ 100).
Example
10 m × 2 m × 3 m gives 60 m³; a 25% factor gives an adjusted 75 m³.
Notes
The shape selector uses the same rectangular arithmetic. Slopes, supports, soil behavior, access, utilities and site conditions are excluded. This is not trench or underground-work safety guidance.
