A free WordPress plugin that drops a live budget calculator into any post, page, or sidebar. Visitors pick a travel style and length of trip; it does the math instantly, right there on the page.
Free to use, GPLv2 licensed.
No account or API key required — it runs entirely on your own site.
An interactive calculator gives people a reason to linger on the page instead of skimming to the next headline.
Set your own daily costs and category split from a normal wp-admin settings screen. No code edits, no rebuilding the page.
It's a static, client-side calculator — no database calls, no external API, nothing that can go down or slow your site.
Grab it from the button above.
In wp-admin: Plugins → Add New → Upload Plugin.
One click after the upload finishes.
Use [wanderbudget_widget], the block, or the classic widget.
Everything lives under Settings → WanderBudget Widget — no theme files to touch.
By default the calculator includes a small link back to WanderBudget.org — that's what keeps this free for everyone to use. If you'd rather not show it, there's a checkbox to turn it off, and the calculator works exactly the same either way.
