Writing about a trip? Give your readers the real price, not just the headline one. Pick a trip, paste one snippet into your post, and a working calculator shows up right there, forgotten costs and all. It's free, and it stays up to date: when we re-check prices each month, every embedded calculator updates on its own.
Where to paste it
WordPress: add a Custom HTML block.
Squarespace: add a Code block.
Wix: Add → Embed code → Embed HTML.
Ghost, Webflow, Blogger: use an HTML or embed block.
The last line of the code lets the calculator grow and shrink to fit. If your platform removes scripts, it still works: it just scrolls inside its frame.
The fine print
Please keep the credit link under the calculator, and don't present the numbers as your own. The calculator includes a few affiliate links (that's how this site stays free) and a note saying so. No sign-up needed. Questions? See the About page.
