Put our calculators on your site, free

Every calculator here can be embedded on your own website with one line of HTML. No signup, no API key, no cost, and no tracking of your visitors. Take the code, paste it, done.

How does embedding work?

Copy the snippet for the calculator you want and paste it into your page, post or template wherever HTML is allowed. It works in WordPress (Custom HTML block), Ghost, Webflow, Squarespace, Wix, Notion embeds, and any hand-written site. The calculator loads inside a responsive frame, adapts to the width you give it, and runs entirely in your visitor's browser.

What we ask in return: the embed carries a small "Powered by My FIRE Calculators" credit linking back to us. That link is how we can afford to give the tools away, so please leave it in place. Everything else is yours to use commercially, indefinitely, at no cost.

What do your visitors get, and what do we collect?

Nothing is collected. The math runs client-side in the iframe, so the numbers your readers type never reach our servers or anyone else's. There are no cookies set by the embed, no analytics beacons and no third-party trackers inside it. That means you can drop it into a page without changing your own privacy policy or consent banner.

Common questions

Is embedding free?

Yes. No signup, no API key and no cost. The embed carries a small Powered by My FIRE Calculators credit linking back to us, and that link is the whole price. Everything else is yours to use commercially, indefinitely.

Do the embedded calculators track my visitors?

No. The math runs client-side inside the iframe, so the numbers your readers type never reach our servers or anyone else's. The embed sets no cookies, fires no analytics beacons and loads no third-party trackers, which means dropping it in does not change your own privacy policy or consent banner.

Where do the embeds work?

In WordPress Custom HTML blocks, Ghost, Webflow, Squarespace, Wix, Notion embeds and any hand-written site where HTML is allowed. The calculator loads inside a responsive frame and adapts to the width you give it.

What assumptions do the embedded calculators use?

The same shared engine as the pages on this site: a 7% nominal return, 3% inflation and 0% fees, giving a 4% real return, at a 4% withdrawal rate, with age 30 and retirement at 65. Your visitors can change all of them under Advanced assumptions. The formulas and defaults are documented on how our calculators work.
