3. Estimates only — not professional advice
All calculations are estimates based on the inputs you provide. Actual material needs, costs, labor, waste, and structural requirements vary by supplier, region, product, site conditions, and code. Verify critical measurements and orders with a qualified professional or supplier. See our Disclaimer for full details. Nothing on this site is professional construction, engineering, or financial advice.

We own the site’s design, text, calculators, diagrams, and code (unless attributed). You may share links and cite our calculators with attribution.

Content and calculators are provided "as-is" and "as-available" without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that formulas suit every project or jurisdiction.
7. Limitation of liability
To the fullest extent permitted by law, Calculator Street and its owner are not liable for any indirect, incidental, special, consequential, or punitive damages, or for over- or under-ordering, cost overruns, rework, delays, or structural issues arising from use of estimates. Your sole remedy is to stop using the site. Some jurisdictions do not allow certain limitations, so these limits may not apply to you.
