Terms & conditions

Last updated: 2026-10-09

These terms apply to your use of freeconcretecalculator.com (the "site"), operated by Free Concrete Calculator ("we", "us"). By using the site you agree to them. If you do not agree, please do not use the site.

1. What the site provides

The site offers free calculators and guides for estimating concrete, gravel, soil, mulch, masonry and related materials, and cost estimates based on prices you enter. Results are estimates for planning and ordering. They are not engineering, legal or professional advice. Please read our disclaimer.

2. Your responsibility for results

You are responsible for checking measurements, confirming quantities and prices with your supplier, following your local building code and, where needed, getting advice from a licensed professional before ordering materials or starting work. Construction carries risk; use appropriate safety equipment and practices.

3. No warranty

The site and its content are provided "as is" and "as available". We work hard to keep calculations accurate and test every formula, but we make no warranties, express or implied, that the site will be error-free, uninterrupted or suitable for a particular purpose.

4. Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of, or reliance on, the site or its results. This includes over- or under-ordered materials, project costs, delays and property damage. Nothing in these terms excludes liability that cannot be excluded by law.

5. Acceptable use

You may use the site for personal and business planning. You agree not to:

• Copy, republish or scrape the site's text, tables, illustrations or code in bulk, or present them as your own.
• Interfere with the site's operation or security, or try to access systems you are not authorized to use.
• Use the newsletter signup to submit someone else's email address without their permission.
• Use automated tools in a way that places an unreasonable load on the site.

You may link to any page and share calculator results, including links made with "Copy link to this result".

6. Intellectual property

The site's text, calculators, code, design and illustrations belong to Free Concrete Calculator or are used with permission. Brand and product names (for example QUIKRETE and Sakrete) are trademarks of their owners and are used only to describe products. We are not affiliated with or endorsed by them.

7. Advertising and third-party links

The site may show ads served by Google and its partners, and links to manufacturers, standards bodies and government sources. We are not responsible for the content, products or privacy practices of third-party sites or advertisers. How advertising data is handled is explained in our privacy policy.

8. Newsletter

If you subscribe, you agree to receive our emails until you unsubscribe. You can unsubscribe at any time with the link in any email.

9. Changes to the site and these terms

We may change, add or remove calculators and content, and update these terms. The "last updated" date shows when the terms last changed. Continued use of the site after a change means you accept the updated terms.
