The calculator runs entirely in your browser. We don't store the prices, dates or guest numbers you enter, and you don't need an account.

Advertising

This site is free because it shows ads from Google AdSense. Google and its partners may use cookies to show ads based on your visits to this and other websites. In the UK and EU we ask for your consent first, and you can change your choice at any time from the privacy link Google shows on the page.

You can read how Google uses information from sites that use its services and turn off personalised ads in Google's ad settings.

Analytics

With your consent, we use Google Analytics to count visits and see which pages are useful. It doesn't tell us who you are. If you decline, Analytics doesn't set cookies.

Hosting

The site is hosted by Vercel, which keeps standard server logs, such as IP addresses, for security and performance.
