Terms

By using BuildCalc you agree to these terms. They are short, and they are written in plain language on purpose.

Last updated: 10 November 2026.

1. The service

BuildCalc provides free home-improvement material calculators and guides. You may use them for personal and commercial projects. You do not need an account, and there is no charge.

2. Results are estimates

Every result on this site is an estimate. Coverage, yield and quantities vary by brand, region, surface condition and waste, and prices vary by store and region. Nothing on this site is a measurement, a quotation, or professional advice. Verify with the product label and a professional before you buy or build. See our Disclaimer.

3. Use responsibly

Do not use BuildCalc for structural or safety-critical decisions — for example, load-bearing slabs, retaining walls, or anything involving gas or electricity. Those need a qualified professional who can see the job. You are responsible for how you use the results.

4. Content and intellectual property

The text, guides and calculators on BuildCalc are ours. You may link to any page, and you may quote short passages with credit. Do not copy whole guides or reproduce the site, and do not use automated tools to scrape the site in bulk.

5. Links to other sites

Some pages link to retailers and manufacturers. Those sites are not ours, and we are not responsible for their content, prices or availability. Some of those links may be affiliate links — see our Affiliate Disclosure.

6. No warranty, limited liability

BuildCalc is provided “as is”, without warranties of any kind. We do not guarantee that the site will always be available or error-free, and we are not liable for over-ordering, under-ordering, project delays, or any other loss arising from using the site. If a calculator is wrong, tell us and we will fix it — that is the remedy we offer.

7. Changes

We may update these terms at any time; the updated version will be posted here with a new “last updated” date. Questions about these terms can be sent to hello@buildcalc.com.
