Embed
Put these tools on your own site
One line of HTML. The whole tool, the answer, the inputs and the assumptions behind it, running inside your page.
The second line is optional. It resizes the frame to fit the tool, without it the frame keeps the fixed height above and scrolls inside.
What your readers will see
The terms, in full
Free, for any site, commercial or not. There is no key to request, no account to make and no limit on how many times it loads.
Keep the attribution. Every embed carries the Valmonk name and a link back. That link is what we get out of this, and it is the only thing we ask for.
We do not track your readers. The tool computes in their browser and sends no figure anywhere, the same promise that holds on our own pages. We count anonymous, cookieless events: which tool loaded and whether someone clicked through to us. No cookies are set, so an embed does not change what your own privacy notice has to say about cookies.
Nothing is for sale inside it. No ads, no affiliate links, no products, and none will appear later, Valmonk does not sell investment products or earn commission on anything a reader does next. Every result is arithmetic on numbers your reader entered, under assumptions they can see and change, and every embed says so on itself.
Two things worth knowing
Numbers do not carry between pages. On our own site a figure entered in one tool pre-fills the next. Inside an embed browsers partition storage per host site, so that does not happen, each embed starts from its defaults, or from whatever is in its link.
You can pre-fill it. Open any tool on our site, set the numbers, and the address bar carries them. Paste that query string onto the end of the embed address and your readers land on those numbers instead of ours, useful when the article is about a specific example.
