Concrete Floor Cost Calculator
Estimate a new concrete floor or finish an existing slab. FloorCalc can calculate square footage, slab volume, finish cost and project range.
Compare the same project across flooring types
These are broad installed planning ranges for the area you entered. Your live estimate above is more specific because it includes scope, waste, prep, removal and region.
| Flooring | Installed range / sq. ft. | Same-area project range |

COST SNAPSHOT
Start with a range. Then price the actual job.
A new concrete slab commonly runs about $6–$12 per sq. ft.; polished or stained finishes on an existing slab commonly run about $3–$15+ per sq. ft.
FloorCalc planning data refreshed August 2026. See methodology and sources.
The number that matters is the total scope.
Product price alone can miss labor, tear-out, subfloor work, waste, stairs, transitions and finishing. FloorCalc exposes those items instead of burying them in one multiplier.

COMMON QUESTIONS
Concrete Floor Cost Calculator FAQ
How much does a concrete floor cost?
A new slab often falls around $6–$12 per square foot before premium decorative work. Polishing or staining an existing slab uses a different cost model, typically around $3–$15+ per square foot.
How much does a 30×30 concrete floor cost?
A 30×30 floor is 900 square feet. Choose New concrete slab and enter the thickness to calculate both project cost and approximate concrete volume.
How many cubic yards of concrete do I need?
FloorCalc converts area and slab thickness to cubic feet, then divides by 27 to estimate cubic yards and adds a small ordering allowance.
Does polished concrete include the slab?
No. Polishing is modeled as a finish applied to an existing suitable concrete slab unless you explicitly choose New concrete slab.
