About these estimates
What updates automatically

Concrete pricing tracks the Federal Reserve's national Ready-Mix Concrete Producer Price Index (FRED series WPU13330101), refreshed on the 2nd of every month.

What's reviewed manually

Decorative finishes (stamped, stained, exposed aggregate), reinforcement, forming, and labor rates have no public live-data source and are reviewed roughly every 3-6 months.

What's not included

This covers the slab pour itself — concrete, standard forming, basic reinforcement, and finish work. It does not include: demolition of an existing slab, extensive excavation/grading, drainage work, or sealcoating.

Building a fence or deck too?

Fence posts and deck footings both need concrete. Check our fence calculator or deck calculator to plan the full project.
