Free Embeddable Construction Calculators
Paste one script tag and a working calculator appears on your page — the same engine as the calculators on this site, with state-adjusted material and labor pricing verified daily against .gov sources. Free, no signup, and no ads inside the widget. Pick a calculator, copy its line, drop it where you want it to render.
How it works
- Copy the
<script>line under any calculator below. - Paste it into your page's HTML where the calculator should appear.
- It loads in an iframe, sizes itself to your column, and updates its prices as our .gov data refreshes — nothing for you to maintain.
Use it free on any site. The widget carries a small "Powered by LiveDataCalc" credit linking back here; please keep it. Prices come from BLS PPI series and BEA Regional Price Parities — see our methodology for exactly how each figure is derived.
Where the prices come from
Every material price and labor rate in these calculators traces to a named federal data series — no proprietary databases, no scraped retail sites. State-level adjustment uses BEA Regional Price Parities.
| Source | Series | Update cadence |
|---|---|---|
| BLS Producer Price Index (via FRED) | 615 price series | monthly |
| USDA National Agricultural Statistics Service | 393 price series | annual |
| U.S. Energy Information Administration | 101 price series | weekly |
| BLS Occupational Employment & Wage Statistics | 21 price series | annual |
| USGS National Minerals Information Center | 1 price series | annual |
| RETAIL_SUPPLIER | 1 price series | as-needed |
