FAQ
Is the embed free to use?
Yes — free for any website, blog or newsletter, with the attribution link kept intact.
Which calculators can I embed?
Any ChainCalories calculator: Chipotle, Panda Express, Starbucks, Subway, Taco Bell, Chick-fil-A or Wendy's. Just change the src path in the snippet.
Can I set a default order?
Yes — every calculator supports URL parameters. Build your order on the calculator page, click 'Copy shareable link', and use that URL as the iframe src.
Does the embed slow my page down?
No — each calculator is a single lightweight static page (no frameworks, no tracking beyond our own analytics) and loads lazily inside the iframe.
Please keep the attribution link when embedding. Nutrition data is verified against each chain's official published values — last verified July 2026.
