Free trading calculators for your website
Risk of ruin, forex lot size and prop firm consistency rule calculators you can add to any page in one step.
Short answer: copy one block of code below into any web page (WordPress: a Custom HTML block) and your visitors get a working calculator. Free for any site, including commercial sites. No sign-up, no cookies, no tracking, no ads, and the numbers people type never leave their browser.
Free to use, on three fair terms
- Keep the small "by Trading Checkup" line under the calculator. It is a normal, visible link; adding rel="nofollow" is fine.
- Do not change the results text or present it as advice from you or from us.
- Each calculator is under 15 KB, loads only when scrolled into view and makes no calls to other servers.
