This is the widget exactly as your visitors will see it. It is the same calculator used on our Boat Loan Calculator page, with the same formula and the same estimate disclaimer.
Option 1: embed the calculator
Paste this code where you want the calculator to appear. The credit line below the frame must stay visible and unchanged.
<iframe id="bpc-calculator" src="https://boatloanpaymentcalculator.com/embed/boat-loan-calculator" title="Boat loan payment calculator" width="100%" height="1350" style="border:0;max-width:960px" loading="lazy"></iframe>
<p style="font-size:13px">Boat loan calculator by <a href="https://boatloanpaymentcalculator.com/">Boat Payment Calculator</a></p>Optional, recommended: add this short script after the code above so the frame's height follows the calculator (inputs stack on phones, and Advanced options make it taller). It only accepts a height number from our domain. Without it, the frame keeps a fixed height of 1,350 pixels and scrolls inside if needed.
<script>
window.addEventListener("message", function (e) {
if (e.origin !== "https://boatloanpaymentcalculator.com" || !e.data) return;
var h = Number(e.data.bpcEmbedHeight);
if (h > 0 && h < 5000) document.getElementById("bpc-calculator").style.height = h + "px";
});
</script>Option 2: link to the calculator
If you prefer not to embed anything, a plain text link works just as well for your visitors:
<a href="https://boatloanpaymentcalculator.com/boat-loan-calculator">Boat Loan Payment Calculator</a> — estimate your monthly boat payment, total interest and payoff date.Privacy and performance
- No tracking: the widget sets no cookies and loads no analytics, advertising or third-party scripts.
- Nothing is stored: calculations run in your visitor's browser; the numbers they enter are not sent to us or anyone else.
- Lightweight: one stylesheet, three small scripts and a self-hosted font, served from our domain. With
loading="lazy"the frame loads only when a visitor scrolls near it. - Isolated: the frame cannot read or change anything on your page.
