Terms & Conditions
Last updated: June 24, 2026
These Terms and Conditions ("Terms") govern your use of The Gravel Calculator website at thegravelcalculator.com (the "Service"). By using the Service, you agree to these Terms.
Use of the Service
The Service is provided free of charge for informational and planning purposes. You may use it for personal, educational, or commercial estimating purposes. You may not use the Service for any unlawful purpose or in any way that could damage, disable, or impair the Service.
Accuracy of Estimates
All calculations and estimates provided by the Service are approximations intended for planning purposes only. Results are based on the density data and formulas we use, which are sourced from industry references. Actual material quantities, weights, and costs may vary due to factors including but not limited to material compaction, moisture content, measurement precision, supplier variations, and regional differences.
You should not rely solely on this calculator for purchasing decisions. We recommend ordering a small amount extra (5-10%) to account for waste, settling, and measurement variations. Always verify quantities with your material supplier before placing large orders.
Intellectual Property
The Service, including its design, code, and content, is owned by The Gravel Calculator and protected by copyright and other intellectual property laws. You may not copy, modify, distribute, or reverse-engineer any part of the Service without written permission.
Limitation of Liability
The Service is provided "as is" and "as available" without warranties of any kind, express or implied. To the fullest extent permitted by law, The Gravel Calculator shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of your use of the Service.
In no event shall our total liability exceed the amount you paid to use the Service (which, since the Service is free, is zero dollars).
Indemnification
You agree to indemnify and hold harmless The Gravel Calculator from any claims, losses, or damages arising from your use of the Service or violation of these Terms.
Links to Third-Party Sites
The Service may contain links to third-party websites. We are not responsible for the content or practices of any third-party sites. Use of third-party sites is at your own risk.
Changes to These Terms
We reserve the right to modify these Terms at any time. Changes will be posted on this page with an updated revision date. Continued use of the Service after changes are posted constitutes acceptance of the updated Terms.
Governing Law
These Terms are governed by the laws of the State of California, United States, without regard to conflict of law principles.
