Using the Widget

Free for any website, commercial or not.
Keep the credit line under the widget ("Concrete calculator by SlabCostCalculator.com"). It is a normal link your readers can follow to the full calculator.
The widget loads from our site, so it always shows our current prices, the same ones as our 2026 price report. It sets no cookies and has no ads or tracking.
Prices are modelled U.S. estimates for planning, adjusted by a location factor per state; they are not quotes. The method is public.

Will the prices in the widget stay up to date?

Yes. Pick a state above and the code changes to open on that state. Visitors can still pick another state in the widget.

Does the widget work on WordPress, Wix and Squarespace?
