Terms of Use

By using concretecalculator.xyz (the "Site") you agree to these terms. If you do not agree, please do not use the Site.

1. What the Site provides

The Site provides free online calculators and educational content for estimating concrete volume, bag counts, materials, weight and cost. All tools run in your browser and are provided free of charge for personal and commercial use.

2. Estimates, not engineering advice

Calculator results are informational estimates based on standard formulas, published material constants and the inputs you provide. They are not a substitute for professional advice. In particular, tools involving structural behavior (including the load calculator and rebar calculator) present screening estimates with stated assumptions — final design of any structural element must be performed or verified by a licensed engineer and comply with your local building code.

3. Accuracy

We work hard to keep formulas, yields and reference data correct, but concrete products vary by manufacturer and market. Always confirm bag yields, mix specifications and prices with your supplier before ordering. We are not responsible for material shortages, overages or costs arising from reliance on Site estimates.

4. Acceptable use

You may not scrape the Site at abusive rates, misrepresent Site content as your own, or use the Site in any way that violates applicable law.

5. Intellectual property

Site content, design and code are owned by Concrete Calculator unless otherwise noted. You may link to any page freely.

6. Limitation of liability

The Site is provided "as is" without warranties of any kind. To the maximum extent permitted by law, Concrete Calculator shall not be liable for any damages arising from use of the Site or reliance on its results.

7. Changes

We may update these terms at any time; the "last updated" date above reflects the current version. Continued use after changes constitutes acceptance.
