Concrete Calculator Terms of Use
Last updated November 7, 2026.
Concrete calculator terms — planning tool only
Concrete Calculator provides educational planning estimates for concrete and related materials. Results are not a mix design, psi rating, rebar schedule, structural calculation, or permit document. Always confirm orders with your ready-mix plant, bag label, drawing, or licensed professional.
No warranty under these concrete calculator terms
The site is provided “as is.” We do not warrant uninterrupted access or that every figure matches a particular brand’s bag yield or a local plant’s batching rules. Published densities and bag yields are common US planning figures documented on the about the math page.
Your responsibility
You are responsible for measurements, unit conversions you override, waste allowances, and the final ticket you call in. Under-ordering or over-ordering can happen when forms are out of square, bases settle, or plants round differently than the tool’s quarter-yard / 0.1 m³ steps.
Acceptable use
Do not scrape the site in a way that degrades service, attempt to break the calculator, or misrepresent results as stamped engineering. Linking to public pages is welcome.
Disclaimer and privacy
Planning limits and liability language also appear on the Disclaimer. Browser data and optional analytics are covered in the Privacy Policy.
