Free business calculator widgets

Try five independent calculators and copy an optional hosted iframe for your website. No account, API key, or subscription is required. These are estimates from your assumptions, not verified business performance or professional advice.

The separate Etsy digital products provide self-contained HTML files for offline use or your own hosting, installation documentation, and a business-use license. They are not purchases of exclusive access to these free demos. Hosted availability is not guaranteed; self-hosting avoids that dependency.

Business Pricing Calculator Widget

Estimate a selling price from unit cost, allocated overhead, and a target margin.

Open standalone demo
Copy iframe code and installation instructions

  1. HTML website: paste the iframe into your page where visitors should see the calculator.
  2. WordPress: use a Custom HTML block with an account allowed to embed iframes. Publish and test the front-end page; editor previews can differ.
  3. Adjust the height to fit your site, especially on phones. This iframe scrolls internally; it does not message or resize its parent.

Hosted embeds require internet and availability of these routes. Your site must permit this host in its frame-src policy. WordPress plans, roles, security plugins, or page builders may remove iframes.

Compare per-unit gross profit, margin on sales, and markup on cost.

Privacy, compatibility, and customization

Calculator inputs stay in the iframe's memory and are cleared on reload. No analytics, automatic redirects, cookies, saving, or API requests are added by the widgets. Normal hosting requests may be logged by your host or The Stack Matrix host. Do not enter confidential information on a shared device.

Use a current JavaScript-enabled browser. Choose a light or dark theme above. A six-digit accent color can be added as ?accent=086b85 (or &accent=086b85 after another parameter). Check contrast after customization. No user input is read from URL parameters.

The downloads are HTML widgets, not Excel files or native WordPress plugins. Offline files require no internet for calculations; attribution links require internet if opened. HTML/WordPress iframe support depends on your hosting plan, permissions, and security policy. No guaranteed traffic, leads, or sales.
