How this calculator works
Volume is length × width × depth, increased by the selected waste percentage.
Formula
V=L×W×D×(1+w/100)Concrete volume in cubic metres including an explicit waste allowance.
Worked example
Verified example is a verified test case used by the calculation engine.
Assumptions and limitations
- Dimensions are rectangular and entered in metres.
- Depth is uniform across the pour.
- Waste is an explicit planning allowance and does not model site-specific loss.
Methodology & sources
This calculator uses deterministic, versioned calculation logic. The formula and verified examples above are part of the calculation definition used by CalcuMint. Technical calculation version: 1.
- NIST SI Guide — Supports consistent dimensional and SI-unit treatment for geometric calculations.
Frequently asked questions
What unit is the result?
The result is cubic metres when all dimensions are entered in metres.
Should I include waste?
Use the waste field only when you want an additional planning allowance.
