1. Your calculations never leave your browser

This calculator requires no account, and every calculation runs entirely inside your own browser. The amounts, rates and timelines you enter are never transmitted to, or stored on, our servers — we do not have servers that receive them. If you use the “Copy shareable link” feature, your inputs are encoded into that URL on your device; share such links only with people you want to see those numbers.

2. Cookies and third-party advertising

This site may display third-party advertising, such as Google AdSense. Third-party vendors, including Google, use cookies (such as the DoubleClick cookie) to serve ads based on a user’s prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings, or manage third-party vendor cookies at www.aboutads.info/choices.

3. Analytics

To understand visit volumes we may use a cookie-free, anonymous analytics service (such as Cloudflare Web Analytics). It does not use persistent identifiers and does not collect personally identifying information.

4. Affiliate disclosure

Some links on this site may be affiliate links, meaning we may earn a small commission if you sign up for or purchase a service through them. This never increases the price you pay, and it never influences the calculator’s math or the editorial content.

5. Your choices

You can block or delete cookies in your browser settings; the calculator itself will keep working, since it does not depend on cookies. This site is not directed at children under 13.
