Embed free, live-data construction cost calculators with a block or shortcode. State-adjusted pricing from U.S. .gov sources, verified daily.

== Description ==

Add a working construction cost calculator to any page with the **LiveDataCalc Calculator** block or the `[livedatacalc]` shortcode. Each calculator gives an instant, state-adjusted estimate — concrete, gravel, asphalt, mulch, topsoil, sand, fill dirt, carpet and more.

Pricing is derived from U.S. Bureau of Labor Statistics Producer Price Index series and U.S. Bureau of Economic Analysis Regional Price Parities, verified daily. The calculators auto-update as that data refreshes — nothing for you to maintain.

* No signup, no API key, no ads inside the calculator.
* Resizes to fit your content column automatically.
* Works in the block editor (with a live preview) and in classic/shortcode contexts.

= External service notice =

The calculators load in an iframe from **https://livedatacalc.com**. When a visitor views a page containing the block, their browser requests the calculator from that domain. No personal data is sent. See the LiveDataCalc privacy policy (https://livedatacalc.com/about/) and methodology (https://livedatacalc.com/methodology/) for how figures are derived.

== Installation ==

1. Upload the plugin .zip via **Plugins → Add New → Upload Plugin**, or extract it into `wp-content/plugins/`.
2. Activate **LiveDataCalc Construction Calculators**.
3. In the block editor, add the **LiveDataCalc Calculator** block and pick a calculator, or place the shortcode:

   `[livedatacalc calc="concrete-cost-calculator"]`

== Frequently Asked Questions ==

= Is it free? =
Yes. The calculators and this plugin are free to use on any site.

= Where do the prices come from? =
BLS Producer Price Index series and BEA Regional Price Parities (US averages, state-adjusted), verified daily. Full methodology: https://livedatacalc.com/methodology/

= Does it slow down my site? =
The iframe is lazy-loaded, so it only loads when scrolled into view.
