Terms of Use

Plain-English terms for using Concrete Pour Calculator. By using this site you agree to them.

Effective date: October 17, 2026

Estimates, not advice — please read this part

Every number on this site is an estimate for planning purposes only. Nothing here is engineering, architectural, legal, or financial advice, and no result is a quote, a bid, or a guarantee of quantity or price. Concrete work is governed by local building codes, frost lines, soil conditions, and load requirements that a website cannot know. Before you order materials or pour, verify quantities with your supplier and requirements with your local building department or a licensed professional.

Accuracy

We work to keep the math right — bag yields are the manufacturers' published figures, and formulas are documented on the pages that use them. But we make no warranty that any calculation, default price, or guidance is complete, current, or right for your project. Default prices are labeled national averages intended as starting points; actual prices vary by supplier and region and change over time. You are responsible for confirming all quantities and prices before purchasing.

Acceptable use

• Use the calculators for your own projects and planning, free of charge.
• Do not attempt to disrupt the site, scrape it at abusive rates, or misrepresent its results as professional engineering.
• Do not rely on this site where a miscalculation could cause injury or structural failure — structural work belongs to licensed professionals.

Intellectual property

The site's text, design, and code are the property of the publisher. You may print or save results pages for your own project records. Bag-yield figures and product names belong to their respective manufacturers; their mention is descriptive only and implies no endorsement.

Third-party links and advertising

This site may link to third-party websites and carries advertising. We are not responsible for third-party content, products, or prices, and a link is not an endorsement.

No warranties; limitation of liability

This site is provided "as is" without warranties of any kind, express or implied. To the fullest extent permitted by law, the publisher is not liable for damages arising from use of this site or reliance on its estimates — including over- or under-ordered materials. Concrete is heavy and job sites are hazardous; nothing on this site replaces safe work practices or professional supervision.

Governing law

These terms are governed by the laws of the State of Washington, USA.

Changes

We may update these terms; the current version will always be posted here with its effective date.
