Acceptance and allowed use
By using Online Calculators, you agree to use the site for lawful, personal, educational, or internal business purposes. You may not interfere with the site, bypass security controls, scrape the service at abusive scale, or use the calculators to mislead another person about an official result.
Calculator pages may include formulas, assumptions, examples, links to sources, and review dates. Those materials are provided to make the calculation transparent, not to create a professional engagement or personalized recommendation.
Calculator results and professional advice
Calculator outputs are estimates based on the inputs you provide and the assumptions shown on the page. They are not financial, medical, legal, tax, insurance, investment, engineering, safety, or other professional advice.
You are responsible for verifying important results against primary sources, official documents, contracts, statements, local rules, and qualified professionals before making decisions.
Content, sources, and third-party links
We work to keep formulas, examples, and source notes clear, but source pages, laws, rates, standards, and external websites can change. Third-party links are provided for reference and do not mean we control or endorse those websites.
You may link to public calculator pages. You may not copy, resell, or repackage substantial parts of the site in a way that suggests affiliation or removes context, assumptions, sources, or disclaimers.
Availability, changes, and contact
The site may change, add, remove, or noindex pages as formulas, sources, product coverage, or review policies change. We may update these Terms when the service changes or when legal requirements require it.
Questions about these Terms can be sent to [email protected].
