Use of the site
FounderCalc provides free calculators "as is", without warranty of any kind. You're welcome to use the tools for personal, educational, or commercial purposes, free of charge and without creating an account.
By using this site you accept these terms. They are governed by French law, and the publisher's identity and registration details are on the legal notice page.
No professional advice
The calculators, explanations, benchmarks and guide sections on this site are published for general information only. They are not financial, investment, tax, accounting or legal advice, and using them creates no professional or advisory relationship of any kind.
Nothing here is tailored to your circumstances. Tax and payroll tools in particular are planning estimates: rates, thresholds, allowances and filing rules differ by jurisdiction and change between tax years. Valuation, forecasting and investment tools depend entirely on assumptions you supply, and small changes to those assumptions can change a result substantially. Confirm any figure that matters with a qualified professional before acting on it.
No guarantees
FounderCalc is provided "as is" and "as available", without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement.
Reasonable care goes into the formulas and the third-party rates quoted here, and errors are corrected promptly when reported — but no guarantee is made that the site is accurate, current, uninterrupted or error-free. Third-party figures such as processor fees and tax rates are reproduced from the providers' published pricing and may change without notice; each page links to the provider's own source so you can verify the current figure.
Do not rely on this site for safety-critical, legal, financial or medical decisions.
Limitation of liability
To the fullest extent permitted by law, the publisher is not liable for any loss or damage — including lost profit, lost revenue, lost data, or any indirect or consequential loss — arising from your use of, or inability to use, this site or anything computed with it. You are responsible for checking any figure before you rely on it.
Nothing in these terms excludes or limits liability where it cannot lawfully be excluded, including liability for death or personal injury caused by negligence, or for fraud. If you are a consumer, these terms do not affect your statutory rights.
Acceptable use
You agree not to use FounderCalc to:
- Attempt to disrupt, overload, or gain unauthorized access to the site or its infrastructure.
- Use automated scraping at a rate that degrades the service for other users.
- Use the tools to generate content for unlawful purposes.
Intellectual property
The site design, text content, and code are owned by FounderCalc unless otherwise noted. Output you generate using the calculators (such as computed figures or exported results) is yours to use freely.
Advertising and affiliate links
Running costs are covered by advertising served by third parties, principally Google AdSense. Advertisements are labelled as such, and their content is chosen by the ad network rather than by the publisher — an ad appearing here is not an endorsement, and the publisher is not responsible for advertisers' products, claims or sites.
Some pages link to third-party products as an affiliate, meaning a commission may be earned if you sign up through that link at no additional cost to you. Every such link is labelled on the page where it appears. Affiliate relationships do not determine the figures, rankings or recommendations in comparison content.
How advertising cookies and EU consent are handled is set out in the Privacy Policy.
Availability
This is a free service with no uptime commitment. The site, or any individual calculator, may be changed, suspended or withdrawn at any time without notice.
External links
Links to external sites are provided for reference. The publisher does not control them and is not responsible for their content, accuracy or privacy practices.
Changes
These terms may be updated from time to time. Continued use of the site after changes are posted constitutes acceptance of the updated terms.
Governing law
These terms, and any dispute arising out of them or your use of the site, are governed by French law. If you are a consumer resident in the EU, you keep the protection of the mandatory provisions of the law of your country of residence, and may bring proceedings in your local courts.
