Calculate wet concrete volume from length, width and depth, with an optional wastage allowance.
Concrete volume
Enter values
How this calculator works
Wet Concrete Volume = Length × Width × Depth.
The selected wastage allowance is then added. The result is shown in cubic metres and cubic feet.
Example
A slab measuring 5 m × 4 m × 0.125 m needs 2.5 m³ before wastage.
Frequently asked questions
Can I use feet instead of metres?
Yes. Select Feet and enter all three dimensions in feet.
Should I add wastage?
A small allowance can help with site loss and unevenness, but the appropriate percentage depends on the work.
Does this calculate cement, sand and aggregate?
Use the Cement Sand Aggregate Calculator after finding the concrete volume.
