What the service provides
Calculators Site provides calculators and explanatory content for general information, education and planning. You can use the current website without creating an account or paying a subscription. We may add, change, correct or remove tools and content.
The site does not provide an individual assessment, a binding quote, a credit decision, a tax filing service or a professional relationship. You are responsible for checking that a tool’s country, period, method and assumptions match the question you are asking.
Understanding calculator results
A result depends on the values you enter, the formula used and any stated rates, rounding rules or exclusions. Some tools estimate real-world outcomes; others apply a mathematical formula. A mathematically correct calculation can still be unsuitable for your circumstances.
Published rates and rules can change. Market figures are snapshots rather than executable prices unless a page expressly states otherwise. Do not assume a currency choice changes the governing country’s law, or that a result includes every fee, allowance, risk or eligibility condition.
Check important results against the relevant official source or a qualified professional before you act. Let us know about a suspected problem through the contact page.
Financial, legal and health information
Financial, tax, benefits, property and legal tools provide general information, not personalised or regulated advice. They do not recommend a product, confirm eligibility or guarantee an application outcome. A lender, scheme administrator, tax authority or adviser may apply different rules to your case.
Health, fitness, nutrition and pregnancy tools provide general educational estimates. They cannot diagnose, treat or prevent a condition, assess an emergency or replace a clinician. Do not change medication or treatment based on a calculator. If you need urgent medical help, contact your local emergency service.
Where a tool has a limited population or an entertainment purpose, follow the scope shown on its page. Do not use an adult screening estimate as a diagnosis or a prediction as a guarantee.
Permitted and prohibited use
You may use the calculators for lawful personal, educational or internal business purposes, subject to these terms. You may link to a page and use an individual result in your own work, with responsibility for checking it and any separate professional obligations.
- Do not attempt unauthorised access, introduce malware, interfere with security or disrupt other users.
- Do not submit unlawful, abusive or deceptive material through the contact form, or use it for unsolicited bulk messages.
- Do not overload the service, evade technical access restrictions, or represent our content or results as an endorsement of your business.
- Bulk republication, commercial redistribution or embedding a copy of the service requires permission unless applicable law or a stated licence allows it.
Content and third-party rights
The site’s original text, design and software are protected by the rights of their respective owners. Published mathematical facts, official information, open-source components and third-party materials may have their own legal status or licences. A link or source citation does not transfer ownership of that source to us.
You may quote or reuse material where the applicable law or licence permits it. For other permissions or a rights complaint, identify the relevant page and material in a message to us.
External links and advertising
Links to official sources, social platforms and other websites are provided for context or contact. Those services control their own content, availability, terms and privacy practices. A link does not mean that the other organisation endorses this website.
If advertising or a commercial partnership is introduced, it should be distinguishable from calculator controls and editorial content. An advertisement is not a recommendation or a guarantee about the advertiser. Our editorial policy explains how commercial relationships should be disclosed.
Availability and responsibility
We aim to provide useful, accurate tools, but do not guarantee uninterrupted availability, freedom from errors, or that every result is complete or current. The service is provided on an “as available” basis to the extent permitted by law.
To the extent the applicable law allows, we exclude warranties not expressly given and liability for losses arising from reliance on a result, an interruption or an external service. These limits do not exclude fraud, deliberate misconduct, or any duty, remedy or liability that cannot lawfully be excluded or limited.
Nothing here removes mandatory consumer or data-protection rights. The laws and courts that apply depend on the circumstances and any mandatory protections available where you live; these terms do not require you to give up those protections.
Privacy and messages
Our privacy policy explains contact messages, service providers and technical information. The cookie policy explains local preferences and optional measurement. Do not send confidential medical, financial or identity documents through the general contact form.
A message is not automatically a public submission or a grant to publish your personal details. If we want to publish an identifiable testimonial or contribution, we should agree that separately with you.
Changes, questions and complaints
We may revise these terms as the service changes. The date above shows the current revision. Changes apply prospectively, subject to any notice or other protection required by law. If you do not accept the revised terms, stop using the service.
For a question, permission request or complaint, contact the website operator with the page address and a description of the issue. A clause found unenforceable does not prevent the remaining terms from applying where lawful.
