Questions

Can I customize the calculator's look?

Not in v1 — the calculator inherits TrueCap's styling so it stays consistent across embeds. If there's demand for color/branding customization, we'll add it.

Do I have to keep the 'Powered by TrueCap' footer?

Yes. The footer is the only ask in exchange for free, hosted, maintained calculators. It's small, tasteful, and doesn't compete with your content.

How does the embed affect page loading?

The iframe uses loading="lazy" and renders in its own document, which limits initial work in supporting browsers. Actual performance depends on the host page, browser, placement, and content-security settings, so measure the published page.

Can I track conversions from my embed?

The attribution link uses utm_source=embed, utm_medium=referral, and a calculator-specific utm_campaign so TrueCap can report aggregate embed traffic. It does not accept partner identity or property data.

What if the calculator changes?

The iframe loads the currently released TrueCap implementation, so reviewed updates appear without replacing the snippet. Keep the attribution intact and periodically verify the embed as part of your own site checks.

Have a real estate audience?

Embed a calculator + write a 200-word post about it. Your readers get a useful tool. You get an interactive page that ranks for calculator queries. We get a backlink. Everyone wins.
