This website provides free finance calculators (mortgage payment, compound interest, and early loan payoff). All calculations run entirely in your browser. The numbers you type are never transmitted to our servers, never stored, and never shared. We do not ask for an account, an email address, or any personal information to use the tools.
This site is supported by advertising through Google AdSense. Google, as a third-party vendor, uses cookies to serve ads on this site.
You can opt out of personalized advertising at any time:
Opting out of personalized advertising does not stop ads from being shown; it only means the ads you see will not be based on your browsing history.
Like most websites, our hosting provider may record standard technical information in server logs (such as the page requested, the referring URL, and the browser type) for security and performance purposes. This information is not used to identify individual visitors.
These tools are intended for a general audience and are not directed to children under 13. We do not knowingly collect personal information from children.
You can disable or delete cookies through your browser settings. Blocking cookies will not affect the calculators, which work without them.
We may update this privacy policy from time to time. Any change will be published on this page with a revised date.
