Free ARM Calculator Widget
Add the ARM Calculator to your own website with one copy-paste snippet. It needs no signup or API key, and there is nothing to maintain. It's the same calculator that runs on this site: loan officers, real estate agents, and housing-market bloggers use embeds like this to let house hunters estimate a payment while they are still on your listing or service page, which keeps them there longer.
Compare an adjustable-rate mortgage payment during its fixed years against the payment after the rate resets, using your own rate assumptions. The widget runs entirely in your visitor's browser, so nobody's inputs are sent to us or to you, and it never shows ads or asks for an email address.

Want the full experience? The complete ARM Calculator on our site adds the methodology behind the math, an FAQ, and where the loan type supports it, a full amortization schedule, which is everything the compact widget leaves out.
Need the install steps? Platform-by-platform instructions for WordPress, Squarespace, Wix, Webflow, Google Sites, and plain HTML are on the widgets hub, along with answers to the general questions about how the embeds work.
ARM Calculator widget FAQs
The same inputs and result summary as the calculator on this site, sized to fit inside your page. Longer output (the amortization schedule, the balance chart, the methodology and the FAQ) stays on the full calculator page, which the widget links to under its results.
No. Every calculation runs in the visitor's own browser. Nothing they type is sent to us or to you, the widget sets no cookies, shows no ads, and never asks for an email address.
