A finished calculator, live on its own page at widgetcalc.com — try it before you build anything.

Most WordPress calculator plugins either need you to write formulas in code, or lock lead capture behind an expensive plan. WidgetCalc is built the other way round: build a pricing calculator, quote calculator or cost estimator in a point-and-click editor at widgetcalc.com, publish it, and this plugin drops it onto any page with a shortcode or block — free plan included, no credit card.

Whatever you’re building it for — a pricing calculator that quotes a price from a visitor’s answers, a quote form for a service business, a cost estimator for a project, or an ROI/savings calculator for a landing page — a WidgetCalc calculator asks a visitor a few questions (spend, team size, hours spent per week — whatever your calculator needs), shows them a result worth sharing (“You could save €4,200/year” or “Your estimated quote: €1,250”), and captures their email before or after that result so every calculation becomes a lead in your dashboard, not just a number on the page.

Why WidgetCalc instead of a generic form plugin or a hand-coded script?

  • No formulas to write. Build the calculator at widgetcalc.com with a visual editor — fields, a formula built by clicking, and a live preview — then paste one key here. Nothing to code on the WordPress side, ever.
  • The lead capture is built in. The calculator is the lead form; you don’t wire up a separate Contact Form 7 or Gravity Forms integration to get the email address.
  • A free plan that actually works. One calculator, unlimited visitors, no time limit — not a 14-day trial.
  • Light and lazy. The calculator loads in an iframe after the rest of your page, so it never blocks or slows down your WordPress site’s own load.

This plugin puts that calculator on a WordPress site with no code:

  • A [widgetcalc] shortcode you can drop into any page, post or widget area.
  • A WidgetCalc block for the block editor (Gutenberg), with a field for the calculator key.
  • A site-wide default calculator key under Settings WidgetCalc, so a single-calculator site needs no attributes at all.

Build your calculator at widgetcalc.com first (a free plan covers one calculator), copy its key from the publish step, and paste it here.

Usage

  1. Create and publish a calculator at widgetcalc.com.
  2. Copy the calculator key shown on the publish step (the part of the embed snippet between /embed/ and .js).
  3. Either:
    • Go to Settings WidgetCalc and paste it as your default key, then add the WidgetCalc block or [widgetcalc] shortcode anywhere with no attributes, or
    • Use [widgetcalc key="your-calculator-key"] to place a specific calculator, independent of the default.

Does this need a paid WidgetCalc plan?

No. The plugin works with WidgetCalc’s free plan (one calculator, WidgetCalc badge shown). Paid plans add more calculators, remove the badge and unlock lead routing.

I don’t want to build the calculator myself — can WidgetCalc do it?

Yes. WidgetCalc also sells a done-for-you service: send your pricing sheet or formula and they build, publish and host the calculator for you, for a fixed one-time setup fee plus monthly hosting. It’s a separate paid service from this free plugin, not a requirement to use it — see the built-for-you offer and its Terms of Service. A link to it is also on this plugin’s own Settings WidgetCalc page.

External services

This plugin loads your calculator from WidgetCalc, the hosted service it is
a shortcut for — it has no function without it.

  • What: a loader script, https://widgetcalc.com/embed/{your-calculator-key}.js,
    requested directly by the visitor’s browser for every page that shows a
    [widgetcalc] shortcode or WidgetCalc block.
  • When: on every page view where the shortcode or block is placed.
  • What data is sent: the calculator key you configured (part of the
    script URL) and the standard request data any script load sends (the
    visitor’s IP address and user agent, to the hosting server). The visitor’s
    own answers inside the calculator (and an email address, if the
    calculator asks for one) are sent to WidgetCalc only if the visitor fills
    in and submits the calculator; the plugin itself sends nothing on their
    behalf.
