Embed this per diem calculator

Run a travel policy page, a staffing agency site, a university travel office or a travel nurse blog? Add the calculator to your page for free. GSA rates update on our side every fiscal year, so your page stays current without any work.

1. Choose a default city (optional)

City pre-selected when the calculator opens

Visitors can still change the city and add other cities to the trip.

2. Copy the code

Paste it where the calculator should appear (a "Custom HTML" block in WordPress, Wix, Squarespace or Webflow).

<iframe src="https://perdiemtrip.pages.dev/widget/" title="Federal per diem calculator (GSA rates)" width="100%" height="1000" style="border:0;max-width:900px" loading="lazy"></iframe>
<p style="font-size:14px">Per diem calculator by <a href="https://perdiemtrip.pages.dev/" rel="nofollow">Per Diem Trip</a></p>

Automatic height (optional)

The frame is 1,000 pixels tall. To make it fit its content (the day-by-day table grows with the trip), add this short script too. It only reads the height sent by the calculator and applies it to the frame.

Auto-height script

<script>
  // Optional: resize the frame to its content.
  addEventListener('message', function (e) {
    if (e.origin !== 'https://perdiemtrip.pages.dev' || !e.data || !e.data.perdiemtripHeight) return;
    var f = document.querySelector('iframe[src^="https://perdiemtrip.pages.dev/widget/"]');
    if (f) f.style.height = e.data.perdiemtripHeight + 'px';
  });
</script>
