Concrete Volume Calculator
Calculate wet concrete volume with a configurable wastage allowance.
Adjusted volume
2.363 m³
Base volume
2.25 m³
Allowance
0.113 m³
How this works
Order volume = length × width × depth × (1 + wastage%).
Worked example
A 5 × 3 × 0.15 m slab is 2.25 m³ before allowance and 2.36 m³ with 5% wastage.
FAQ
What is the Concrete Volume Calculator used for?
Calculate wet concrete volume with a configurable wastage allowance. It is intended for quick planning, checking, and everyday decisions.
Can I use the result for a final contract or design?
Use it as a planning estimate. Use structural drawings for member dimensions and do not substitute this for mix design.
How can I improve the accuracy?
Use measured quantities, current supplier or lender rates, the correct units, and compare the result with drawings, invoices, or professional advice where the decision is safety-critical.
