Calculators

Calculators run entirely in your browser. The numbers you enter are not sent to us; they only appear in your page's URL so you can share results if you choose.

Analytics

We use Cloudflare Web Analytics, which does not use cookies, and Google Analytics, which may set cookies to measure visits, pages viewed and referral sources. Google Analytics data is aggregated and used only to improve the site.

Advertising

We use Google AdSense to show ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and 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 can opt out of personalized advertising in Google Ads Settings or at aboutads.info. Learn how Google uses information from sites that use its services.

Visitors in the European Economic Area, the UK and Switzerland are asked for consent through a Google-certified consent banner before personalized ads or analytics cookies are used.

If you subscribe to our email newsletter, your email address is stored by our newsletter provider and used only to send the newsletter. Every email has an unsubscribe link.

Hosting and security

The site is served by Cloudflare, which processes IP addresses and request data to deliver pages and protect against abuse.

Your choices

You can block or delete cookies in your browser settings. California, EU and UK residents may request access to or deletion of personal data we hold; since we hold almost none, contact us on X and we'll respond within 30 days.
