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.

Will the calculator slow down my site?

No. The iframe loads lazily (loading="lazy") so it only fetches when scrolled into view. Renders independently of your page so it can't block your content from showing.

Can I track conversions from my embed?

The attribution link uses utm_source=embed plus a per-calculator utm_campaign so we can report aggregate traffic. If you want per-site attribution, add ?ref=<your-site> to the iframe src — we'll forward it on through to TrueCap and pass it to GA.

What if your calculator math changes?

Embeds auto-update because they load from TrueCap servers. You always get the current version. We commit to backward-compatible URLs — embed code you paste today keeps working forever.

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.
