Terms of Use
Terms governing use of CalculateGravel — calculator estimates are for planning use only, not engineering advice. Verify quantities with your local supplier.
CalculateGravel is free to use. We work hard to keep numbers accurate, but they're estimates, not engineering specs. Confirm with your supplier before ordering. Don't republish our articles whole. If something on the site causes confusion, email us and we'll fix it.
Use of the site
CalculateGravel is a free reference tool. You may use it for any personal or commercial purpose at no charge. You may share calculator results, link to any of our pages, and reference our content with attribution.
No professional advice
CalculateGravel's calculators and articles are reference material, not engineering or construction advice. For any project where structural failure could cause harm to people or property, hire a licensed professional.
Accuracy
We work hard to keep our densities, formulas, and recommendations accurate, and we publish our methodology openly. That said, real-world gravel densities vary by source and moisture, and our cost figures are illustrative only. Always confirm with your local supplier and your local building codes before ordering.
Limitation of liability
CalculateGravel is provided "as is." We are not liable for any decisions made on the basis of information from this site, including but not limited to over-ordering, under-ordering, project cost overruns, or installation issues.
