</iframe>Why a hosted widget beats DIY
Three things you get for free
You could code a mortgage calculator yourself. Here's why most professionals don't.
Single iframe — no plugin
Paste one snippet anywhere HTML works. No WordPress plugin required, no jQuery, no theme conflicts.
White-label your brand
Custom colors, logo, fonts, and CTA copy. The calculator reads as part of your site, not a third-party widget.
Lead capture on every run
Every calculation routes the visitor to your CRM, Calendly, or webhook with the full scenario as JSON.
Works everywhere
Embeds anywhere HTML works
The CalcWidgets embed is a standard iframe. If your CMS lets you paste HTML or an embed snippet, our calculators work — no plugin, no compatibility matrix.
