SellersCalc

For your website

Put a calculator to work on your site

Free embed of any calculator here — or a custom-branded, lead-capturing version built for your business in 48 hours.

Option 1: Embed free

Pick a calculator, paste the snippet into any page (WordPress, Shopify, Webflow, plain HTML). It stays up to date automatically — we host it, you embed it. Keep the credit link below the widget intact; that's the deal for free use.

Option 2: We build yours — $299

A calculator like these, but for your business: your numbers, your branding, your domain — with a lead-capture form that sends every submission straight to your inbox. The same interactive-calculator playbook that outconverts static pages, done for you.

  • Delivered within 48 hours of order confirmation.
  • You get the files — a static bundle plus a one-page deploy guide (drag-and-drop hosting walkthrough). You host it, you own it; no subscription, no lock-in. Deployment support beyond the guide isn't included at this price.
  • Lead capture to your inbox via your own form service or email — we never store your leads.
  • 2 builds per month. Small capacity, kept deliberately — confirmation may take 1–3 weeks depending on availability. Payment by card (Stripe) after confirmation, never up front.

Common questions

Can I remove the credit link on the free embed?

No — the visible credit link is the price of the free embed (see our terms). If you need an unbranded calculator, that's exactly what the $299 custom build is for.

What does the $299 build include, exactly?

One calculator (your formula or one of ours adapted), your colors and logo, a lead-capture form wired to your email or form service, mobile-ready and accessible, delivered as files you host. One revision round included.

Do the free embeds track my visitors?

No. Embeds run no analytics, set no cookies, and show no consent banners. All calculation happens in the visitor's browser.
