Free FIRE calculators for your website

Copy the code and put a working FIRE calculator on your blog or site.

Put a working calculator on your blog, newsletter page or client site. Copy the code under the calculator you want and paste it into your page: it resizes itself, works on phones and keeps every number in your reader's browser.

Who it is for

Personal finance and FIRE bloggers who want a calculator next to a post about the 4% rule, coast FIRE or early retirement.
Financial planners, coaches and educators who want clients or students to try their own numbers.
Forums, libraries and community sites with a money or retirement section.

It works on any page that accepts HTML: the Custom HTML block in WordPress, an HTML card in Ghost, a Code block in Squarespace, Embed HTML in Wix or a plain HTML page. It is free; please keep the credit link under the calculator.

What is inside the iframe

The same calculator as on Enough Path, without our menu: no ads, no cookies, no analytics and no tracking. The numbers your readers type stay in their browser and are never sent anywhere. Results are educational information, not financial advice; the formulas are in our methodology.
