Free calculators for your site
Copy one line of HTML to put the utilization or payoff calculator on your own page. Free, no sign-up, no tracking.
Each widget is the same calculator this site runs, in a frame tall enough for a phone-width column. Paste the line into your page's HTML where you want it. On a column wider than about 740 pixels the inputs and results sit side by side, so you can lower the height to fit.
The terms
Free to use on any site, including commercial ones. The widget sends nothing anywhere and sets no cookies: what a reader types stays in their browser. It carries one small link back to this site, which is the whole price.
If something breaks
The widgets are part of this site, so a fix here fixes every copy. Report a problem through the corrections page.
How this page was made
Drafted on October 25, 2026 with a language model from the sources listed, every source opened that day, and sampled by the editor after publication. Every figure is computed by the same code the calculators run. General information, not financial or legal advice: nothing here computes a credit score or answers one reader's situation.
