Estimate the volume of concrete needed for your construction project
Frequently Asked Questions
What is a concrete calculator?
A concrete calculator helps estimate how much concrete you’ll need for a construction project, based on length, width, and depth.
How do I calculate concrete volume?
Multiply length × width × depth (in feet), then divide by 27 to convert cubic feet into cubic yards — the standard unit for concrete.
What units does this calculator use?
This tool uses feet for length and width, and inches for depth. The result is given in cubic yards.
Is the estimate accurate?
It provides a close estimate. Always order 5–10% extra to account for spillage, over-excavation, or slight errors.
Is this calculator free to use?
Yes, it’s completely free. No signup or payment required.
