Concrete Calculator helps you volume for slabs and footings. It belongs to the Materials group within home and construction tools on The Daily Tools. Enter your values and review the result with the assumptions shown on the page.
Definition: Concrete Calculator is a free, browser-based calculator for volume for slabs and footings.
Formula
Volume = length × width × depth (rectangular); round forms use π × radius² × depth; then add the selected waste allowance
Calculation steps
- The core formula: Volume = length × width × depth (rectangular); round forms use π × radius² × depth; then add the selected waste allowance
- Enter your values in the fields above — units and assumptions are under your control.
- The Daily Tools computes the result instantly in your browser using JavaScript.
- Review the result panel for the primary output and supporting breakdown values.
Worked example
Example: Using the Concrete Calculator
Inputs: Enter values relevant to materials — for example, the measurements or amounts described in the tool fields above.
- Open the Concrete Calculator and review the input fields.
- Apply the formula: Volume = length × width × depth (rectangular); round forms use π × radius² × depth; then add the selected waste allowance
- Adjust inputs to compare scenarios side by side.
You receive an immediate volume for slabs and footings — useful for planning and comparison.
