Concrete Volume Calculator

What you will get

1. Needed

See the estimated project quantity from your measurements.

2. Buy

Add waste and round to complete bags, boxes, cans, bundles or delivery quantities.

3. Check

Review product coverage, site conditions, local requirements and supplier details before ordering.

Quick answer: Calculate concrete volume in cubic feet, cubic yards, cubic meters, and bag equivalents for slabs, footings, patios, and foundations. Start with actual measurements, use the product label for coverage or yield, and treat the result as a planning estimate until site conditions and supplier requirements are confirmed.

Measure a simple rectangular section and see the net volume plus a practical ordering allowance.

Rectangular volume formula

Use this page for slabs, patios, pads, footings, and other simple rectangular sections. Split irregular projects into measured rectangles and add the results.

volume = length × width × thickness
order volume = volume × (1 + waste)

Ordering note: ready-mix suppliers may require a minimum order and may recommend a different allowance for pumping, access, or site conditions.
