What this site is
Calculate My Reno is a free set of materials calculators for planning DIY and trade jobs. By using the site you agree to these terms. If you do not agree with them, please do not use the calculators.
The fair-use ground rules.
Calculate My Reno is free to use, and these terms keep things simple and honest. No dense legal padding - just what you can expect from the calculators and what we ask in return when you use them.
Estimates only
Every result is an estimate built on standard formulas and wastage allowances, not a quote or a guarantee. Real jobs vary, so always check quantities against your own measurements and your supplier before you order. See the disclaimer for the full detail.
Use at your own risk
We provide the calculators "as is" and cannot promise they are error-free or available at all times. To the extent the law allows, we are not liable for any loss, shortfall, surplus or wasted spend that follows from relying on a result.
Intellectual property
The calculators, copy, layout and branding on this site are ours. You are welcome to use the results for your own projects, but please do not copy, scrape or republish the tools or content as your own.
Ads and third parties
The site is free and supported by advertising through Google AdSense. Ads and any linked third-party sites are run by others - we are not responsible for their content, products or privacy practices. How we handle your data is covered in the privacy policy, and what gets set on your device is in the cookie policy.
Changes to these terms
We may update these terms as the site grows. Continued use after a change means you accept the new version, so it is worth checking the date below now and then.
In short
Use the calculators freely to plan your job, treat every number as an estimate to double-check, and we will keep the tools free and useful. That is the deal.
