Put a +EV calculator on your site

Run a betting blog, tipster page, or affiliate site? Give your readers a real, working expected-value calculator — with one line of code. It's free, needs no signup or API key, and always stays up to date.

Option 1 — Script embed (recommended)

Paste this where you want the calculator to appear. The <div> marks the spot; the script renders it. Include the script once per page even if you add several calculators.

<div class="ironmarker-ev-calc"></div>
<script src="https://ironmarker.com/embed/ev-calculator.js" async></script>

Option 2 — iframe embed (no JavaScript)

Some platforms (e.g. hosted WordPress.com, certain page builders) strip <script> tags. Use this self-contained iframe instead — it resizes to fit:

<iframe src="https://ironmarker.com/tools/embed/ev-calculator/"
        width="100%" height="360" style="border:0;max-width:440px"
        title="Iron Marker EV Calculator" loading="lazy"></iframe>

Why add it?

• Genuinely useful to your audience. Betting readers actually use an EV calculator — it's a sticky, practical tool, not a banner.
• Zero maintenance. We host and update it. The math stays correct; you do nothing.
• Lightweight & safe. A few kilobytes, async, no dependencies, scoped styles that won't touch your CSS.
• Free forever. The only ask is the small "Powered by Iron Marker" credit link, which stays in place.

The embeddable calculator is educational and for informational purposes only — not betting or financial advice. Must be 21+. Problem gambling? Call 1-800-GAMBLER.
