Terms of Use

Last updated: 24 July 2026

By using calcbasepro.com you agree to these terms. If you do not agree with them, please do not use the site. The terms exist for one main reason: to be clear about what a free online estimate can and cannot promise.

What you may do

You are welcome to use every calculator, free of charge, for personal or commercial planning work. You may link to any page, quote reasonable excerpts with attribution and a link, and share results with clients or colleagues.

What you may not do

You may not scrape, copy or republish the site's content or tools wholesale; wrap the calculators in frames or apps that hide their origin; use automated traffic to overload the site; attempt to access administrative areas; or present a CalcBasePro estimate as a professionally certified calculation. The site's code, text, and design are the intellectual property of the site owner unless otherwise noted.

Accuracy and reliance

Each calculator implements the formulas and reference values stated on its own page, and each is verified against a worked example before publication. However, all results are estimates for planning purposes. They depend entirely on the values you enter and on stated assumptions that may not match your situation. You are responsible for verifying any result before spending money, submitting designs, or making health decisions based on it. The disclaimer sets out category-specific limits and forms part of these terms.

No warranty; limitation of liability

The site is provided “as is”, without warranties of any kind, express or implied, including fitness for a particular purpose. To the maximum extent permitted by law, the site owner is not liable for any loss or damage — including material over- or under-ordering, design errors, lost profits or consequential damages — arising from use of, or inability to use, the site or its results.

Advertising and external links

The site shows third-party advertising and links to external resources. We do not control and are not responsible for the content, products or privacy practices of advertisers or linked sites.

Changes and termination

Tools, content and these terms may change or be withdrawn at any time without notice. Continued use after a change constitutes acceptance. If any clause of these terms is found unenforceable, the remainder stays in effect.
