Why one embed, not twelve
- Nobody adds twelve iframes to one page. One embed with a dropdown covers liquidation, PnL, position sizing, funding, and the rest at once.
- Deterministic math, verified against 35 canonical test vectors (see /verify), not an approximation you have to maintain.
- Live prices and funding rates from 17 exchanges, no API key or backend work on your side.
- Free, indefinitely, for a small attribution link.
Prefer just one calculator?
If a page is specifically about one topic, e.g. an article on liquidation risk, you can embed that single calculator instead of the full suite. Pick one:

Is this really free?
Yes. No signup, no API key, no usage cap. All we ask is that you keep the small attribution link at the bottom, which opens in a new tab and never redirects your visitors away from your page.
Why one embed instead of picking a single calculator?
A visitor rarely wants exactly one calculation and nothing else. The suite embed drops in once and lets them switch between all 12 calculators from a dropdown, so you get full coverage without adding twelve separate iframes to your page.
Can I embed just one specific calculator instead?
Yes, if a specific article is about one topic (e.g. liquidation) and you want that single tool inline, each calculator also has its own standalone embed. Individual snippets are listed further down this page.
Does it work on WordPress, Wix, Webflow, or a plain HTML site?
Anywhere that accepts a standard <iframe> embed: WordPress (via an HTML/Custom HTML block), Wix, Webflow, Squarespace, Ghost, or a hand-written page.
Does the data stay up to date?
Yes. Each calculator pulls live prices and funding rates from the exchange it references at load time. There is nothing on your end to keep updated.
Will it slow down my page?
The iframe loads lazily and is self-contained, so it does not block the rest of your page from rendering — same as embedding a YouTube video or a tweet.
