What you get, and what we ask

  • The same engine as our own pages. Every figure comes from the calculation engine covered by 444 tests checked against published IRS and SSA figures — not a simplified copy.
  • Nothing tracked.The embed loads no analytics and sets no cookies on your visitors. Your readers' inputs stay in their browser, exactly as on our site.
  • One visible credit link. That is the whole price. Keep the attribution line under the calculator and you can use it commercially, on as many pages as you like.

Presetting the scenario

Add any calculator input to the URL and the embed opens on those numbers — useful when the widget sits inside an article about a specific case. For a mortgage on a $650,000 home:

https://daycents.com/embed/mortgage?homePrice=650000&rate=6.5

Input names match the ones in the address bar on any calculator page — set the values you want there, then copy them across.

Want it without our branding?

Advisers, brokers and lenders who need the calculators under their own name — no attribution, their colours, their logo on the PDF — can have that. Tell us what you need and we'll set it up.
