UNDERSTAND YOUR RESULT
Understand Your Concrete Quantity
Calculate the volume of your chosen shape before adding an explicit waste allowance. The result does not specify a structural mix or design.
Measure each dimension
Volume does not establish a safe concrete grade or structural design. Order allowance accounts for your stated waste, not a certified mix.
Review volume and allowance
Review the displayed breakdown and assumptions before using this estimate.

What changes your result?
- Choose the correct solid. Rectangular volume uses length, width and depth. A cylinder uses radius squared, π and height.
- Keep mix design separate. Volume does not establish a safe concrete grade or structural design. Order allowance accounts for your stated waste, not a certified mix.
Assumptions and limits
Confirm measurements, inclusions and price assumptions. These planning results do not replace professional engineering, legal or lender advice.
Results retain the assumptions you selected. Compare like-for-like areas and avoid counting the same item twice.
View Technical Calculation Details
Rectangular V=L×W×D; cylinder V=π×(diameter/2)^2×D; order volume=V×count×(1+waste/100).
Currency totals: 2 decimal places; geometry and quantities: 6. Whole units/boxes round upward with floating-point ULP correction; internal calculation precision is retained.
