Acceptance of terms
By using HomeCalc, users agree to these terms. HomeCalc provides free calculators and guide content for homeowner planning. If a user does not agree with these terms, they should not use the site.
Planning estimates only
HomeCalc results are estimates based on user-entered measurements and assumptions. The site does not provide professional construction, engineering, surveying, legal, pesticide, code, permit, or safety advice. Users are responsible for confirming final details with product labels, suppliers, contractors, local authorities, or qualified professionals when appropriate.
User inputs
Users are responsible for entering accurate measurements and product values. Incorrect area, depth, coverage, bag size, coat count, panel width, or other inputs can produce incorrect results. HomeCalc does not guarantee that any calculated quantity will be sufficient for a specific project.
Allowed use
Users may use HomeCalc for personal planning, comparison, and educational purposes. Users may not abuse the site, attempt to disrupt it, scrape it at unreasonable volume, copy the entire site as a competing service, or use it in a misleading way.
No warranties
HomeCalc is provided as-is and as-available. The site may contain errors, omissions, broken links, outdated examples, or temporary service issues. HomeCalc does not guarantee uninterrupted availability, complete accuracy, or fitness for a particular project.
Limitation of liability
To the fullest extent allowed by law, HomeCalc is not liable for losses, project costs, material shortages, over-ordering, code issues, failed installations, safety problems, or other damages resulting from use of the site or reliance on estimates.
Third-party services
HomeCalc may use third-party services for maps, hosting, analytics, advertising, fonts, and other site features. Those services may operate under their own terms and privacy policies.
Changes
HomeCalc may update these terms when the site changes. Continued use of the site after updates means the user accepts the revised terms.
Last updated: June 16, 2026.
Accuracy and availability
HomeCalc attempts to keep calculators and guides understandable and useful, but errors can happen. Pages may be updated, removed, renamed, or temporarily unavailable. Users should not rely on HomeCalc as the only source for an important purchase, installation, permit, or safety decision.
Some calculations depend on browser features, JavaScript, map services, or third-party resources. If a feature does not load, users should refresh, try another browser, or contact HomeCalc with details. HomeCalc is not responsible for temporary failures of third-party services.
Intellectual property
The HomeCalc name, page layout, calculator text, and guide content are provided for use on this website. Users may link to HomeCalc pages and use the calculators for planning, but may not copy the site in bulk, remove branding, or republish the content as a competing calculator site without permission.
Accuracy of calculator results
HomeCalc tries to keep formulas understandable and useful, but the result is only as accurate as the measurements and assumptions entered by the user. Users should review the formula notes, product labels, supplier instructions, and local requirements before purchasing material or starting work.
No professional relationship
Using HomeCalc does not create a contractor-client, engineer-client, surveyor-client, legal, or professional advisory relationship. The site provides general planning information only. Users remain responsible for deciding whether a project is safe, legal, permitted, and appropriate for their property.
Changes to the site
HomeCalc may update calculators, formulas, examples, pages, links, and policies to improve clarity or comply with changing requirements. If a page is updated, the current version on the site controls. Users should not rely on an old downloaded or cached version for final project decisions.
Third-party services and links
HomeCalc may rely on third-party services for maps, fonts, advertising, analytics, hosting, or external resources. Those services may have their own terms and privacy practices. External links are provided for convenience or context and do not mean HomeCalc controls or endorses every statement on those sites.
Availability
HomeCalc may be unavailable because of hosting problems, maintenance, browser issues, third-party service outages, or code changes. Users should not rely on the website as the only copy of important project information. Save or copy estimates when planning a purchase.
