Terms of Use

Last updated: July 31, 2026

These terms set the ground rules for using the BizArith website and calculators.

Acceptance of these terms

By accessing or using BizArith, you agree to these Terms of Use. If you do not agree, do not use the site.

What BizArith provides

BizArith is a free informational website with business calculators for planning, learning, and comparison. The current version does not offer user accounts or paid subscriptions.

You may use calculator results in your personal or business work. Results are estimates based on the information you enter and are subject to the separate Disclaimer.

Acceptable use

You may use the site for lawful purposes. You may not misuse BizArith, attempt to bypass its security, interfere with its operation, introduce malicious code, or place automated load on the service in a way that disrupts access for others.

Site content and intellectual property

The BizArith site design, branding, software, and original written content are protected by applicable intellectual-property laws. These terms do not claim ownership over public-domain material, commonly known mathematical formulas, or facts.

You may not copy or redistribute substantial portions of the site or present BizArith branding or original content as your own without permission. This does not prevent normal use of calculator outputs in your business.

External services and links

BizArith does not currently include third-party embeds or integrations. If a page links to an external website, BizArith does not control that site and is not responsible for its content, availability, or practices.

Availability and accuracy

BizArith is provided on an “as available” basis. The site may be changed, interrupted, or unavailable, and no promise is made that every feature or result will always be complete, current, or free of errors.

Responsibility for your decisions

You are responsible for reviewing inputs, checking important calculations, and deciding whether a result is appropriate for your situation. To the extent permitted by applicable law, BizArith is not liable for indirect, incidental, or consequential loss arising from use of, or inability to use, the site. Nothing in these terms excludes liability that cannot legally be excluded.

Changes

BizArith may change, suspend, or discontinue parts of the site. These terms may also be updated when the service or its practices change. The revision date appears at the top of this page, and continued use after an update means the updated terms apply to that use.
