Advertising Disclosure
How we support free access
Calculator Hub's calculators are free to use. To help cover the cost of running the site, we may display advertising from third-party ad networks, such as Google AdSense, in designated areas of the site.
Ad placement principles
We place ads in clearly separated areas of the page — never inside calculator input fields, never styled to imitate a calculator button, and never positioned to cause accidental clicks. Advertising never influences the accuracy of our calculators or the content of our articles.
Third-party advertising and cookies
Advertising vendors may use cookies to serve ads based on your prior visits to this or other websites. See our Privacy Policy for more on cookies and your choices, including opt-out mechanisms offered by ad networks.
Editorial independence
Advertising on this site does not constitute an endorsement of any advertiser or product by Calculator Hub, and no advertiser has influence over our calculators, formulas or editorial content.
