This tool is built for fast cost per square foot planning when you already know local labor and wire/rebar rates per sf. It is not a replacement for a dispatch-level ready-mix takeoff.
Which concrete pricing tool should I use?
- This page (Floor cost per sf): Labor and rebar entered per square foot with concrete priced per yard.
- Concrete cost calculator: Full project budget—material, delivery, labor, rebar, finish, $/sf.
- Slab quote calculator: Markup-ready contractor quotes.
- Ready mix calculator: Yards, truck loads, and delivery fee.
Floor estimating tips
- Separate mobilization from $/sf labor. Small slabs still need setup time—do not underbid tiny pours.
- Match thickness to use. Garages and drives often need more than light patio thickness.
- Pair with volume tools. Cross-check yards on the concrete slab calculator before pricing.
Concrete Floor Cost FAQ
How is this different from the concrete cost calculator?
This page uses per-square-foot labor and rebar rates. The concrete cost calculator adds delivery, finishing, and itemized project lines for full bids.
Does this include finishing and saw cuts?
Include those in your labor $/sf or use the full concrete cost calculator with a finishing line.
Is reinforcement always required?
Requirements vary by slab use, design, and code. Use project-specific specifications.
What is a typical labor rate per square foot?
Many residential markets run $6–$12 per sf for place and finish before special finishes—use your crew’s history.
