Effective date: September 24, 2026

By accessing or using DIY Material Calc, you agree to these Terms of Use. If you do not agree, do not use the site.

Planning tools only

The calculators and content provide general estimates for planning and educational purposes. They are not engineering, architectural, legal, tax, safety, code-compliance, or professional construction advice. You are responsible for verifying measurements, product specifications, prices, site conditions, permits, codes, and supplier quantities before purchasing or building.

No guarantee of results

Material properties, coverage, density, compaction, waste, packaging, prices, and local requirements vary. Results may contain errors or may not fit your particular project. The site is provided “as is” and “as available,” without warranties of accuracy, completeness, fitness for a particular purpose, or uninterrupted availability, to the maximum extent permitted by law.

Permitted use

You may use the site for lawful personal or business planning. You may not misuse the site, interfere with its operation, attempt unauthorized access, introduce malicious code, scrape it in a manner that disrupts service, or copy and republish substantial portions of its software, design, or content without permission.

Intellectual property

The site’s original software, design, branding, and editorial content are protected by applicable intellectual-property laws. Product names and third-party marks belong to their respective owners.

Third-party services and links

The site may link to suppliers, advertisers, affiliates, or other services. DIY Material Calc does not control their products, availability, pricing, security, or policies, and is not responsible for third-party content or transactions.

Limitation of liability

To the maximum extent permitted by law, DIY Material Calc and its service providers will not be liable for indirect, incidental, special, consequential, or punitive damages, or for losses arising from reliance on estimates, purchases, project delays, property damage, data loss, or inability to use the site. Some jurisdictions do not allow certain exclusions, so parts of this limitation may not apply to you.

Changes and termination

Features, content, and these terms may change. The current effective date will be shown on this page. Access may be limited or discontinued when reasonably necessary for security, maintenance, abuse prevention, or legal compliance.
