Concrete Floor Cost Calculator
Plan a concrete floor finish—from plain slab to polished or stained—using square footage, finish tier, and common prep like vapor barrier, rebar, or demo.
Your project
Floor area (sq ft)iFloor area (sq ft) Measure the finished floor area receiving this pour or finish. Exclude stairs and exterior pads unless they are in the same scope. | |
|---|---|
Finish typeiFinish type Plain is a basic troweled slab surface. Broom adds slip texture. Polished and stained are decorative interior finishes with more labor. | |
Your stateiYour state Scales U.S.-average labor and material midpoints for typical state-level pricing. It is not an on-site bid. |
How to use this calculator
- Enter the floor area in square feet.
- Select plain, broom, stained, or polished finish pricing.
- Toggle vapor barrier, rebar, and demo if they apply.
- Choose your state and compare the line-item total.
Results explained
Finish rate × area forms the base. Optional vapor barrier, rebar, and demo add per-square-foot lines, then the state multiplier scales the whole estimate.
Quick reference: concrete floor midpoints
Installed U.S.-average midpoints before the selected state adjustment.
| Scope | Midpoint |
|---|---|
| Plain slab finish | $6.00/sq ft |
| Broom finish | $7.50/sq ft |
| Stained concrete | $10.00/sq ft |
| Polished concrete | $12.00/sq ft |
| Vapor barrier | +$0.80/sq ft |
| Rebar | +$1.20/sq ft |
| Demo existing | +$2.50/sq ft |
Rates are planning midpoints; difficult access, repairs, and minimum job charges can shift quotes.
How the estimate is built
Total ≈ (sq ft × finish $/sq ft) + Σ(selected option $/sq ft × sq ft), then × state multiplier. Thickness changes, radiant tubing, and decorative aggregates are outside this model.
Example scenario
An 800 sq ft broom-finish floor with vapor barrier is about $6,640 at U.S. average ($7.50 × 800 + $0.80 × 800).
FAQ
Is this the same as a concrete slab pour?
Close, but finish choice matters. A structural slab quote may price thickness and forms separately; this tool focuses on finish-oriented midpoints for floors.
Do I need a vapor barrier indoors?
Often yes on ground-contact slabs. Moisture can ruin coatings and flooring—ask a local contractor about site conditions.
What drives polished concrete higher?
Multiple grind passes, densifier, and sealing labor. Darker stains or high-gloss specs also add time.
