Why sites add it

Readers do something, not just read

An interactive calculator gives people a reason to linger on the page instead of skimming to the next headline.

Your rates, your control

Set your own daily costs and category split from a normal wp-admin settings screen. No code edits, no rebuilding the page.

Nothing to maintain

It's a static, client-side calculator — no database calls, no external API, nothing that can go down or slow your site.

Set it up in four steps

1

Download the zip

Grab it from the button above.

2

Upload it

In wp-admin: Plugins → Add New → Upload Plugin.

3

Activate

One click after the upload finishes.

4

Drop it in

Use [wanderbudget_widget], the block, or the classic widget.

Make it yours

Everything lives under Settings → WanderBudget Widget — no theme files to touch.

  • Baseline daily cost for each travel style, and how it splits across categories
  • Accent color, to match your site
  • Always-light appearance, or match each visitor's device

About the link back

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.
