Concrete Patio Cost Calculator
Estimate installed cost for a broom-finish concrete patio — material plus finishing labor — and see what decorative upgrades add per square foot.
How this calculator works
This combines material cost (cubic yards of concrete, from the standard slab-volume formula, times your price per cubic yard) with finishing labor (your patio’s area times a per-square-foot broom-finish labor rate). Both price fields are editable placeholders.
Formula: Cubic yards = (Length ft × Width ft × Depth ft) ÷ 27. Total cost = (Cubic yards × Price/yd³) + (Area sq ft × Labor rate/sq ft).
Worked example
A 12 ft × 12 ft (144 sq ft) patio at 4 inches, $150/yd³ material, $6/sq ft labor:
- Depth in feet: 4 ÷ 12 = 0.3333 ft
- Cubic yards: (12 × 12 × 0.3333) ÷ 27 ≈ 1.7778 → 1.78 yd³
- Material cost: 1.7778 × $150 ≈ $266.67
- Labor cost: 144 × $6 = $864.00
- Total estimated cost: $1,130.67
Cost reference (at default rates)
| Patio size | Estimated total cost |
|---|---|
| 6 ft × 6 ft | ~$283 |
| 12 ft × 12 ft | ~$1,131 |
| 24 ft × 24 ft | ~$4,523 |
How to measure your area
Measure the full patio footprint in feet, including any curved or irregular edges by breaking the shape into rectangles and summing their areas. If the patio steps down or wraps around a corner of the house, calculate each section separately and add the totals.
Frequently asked questions
What finish does this estimate assume?
A standard broom finish — the most common and least expensive patio finish, at $6/sq ft labor in the default. Decorative finishes like stamping or exposed aggregate cost noticeably more; see the Stamped Concrete Cost Calculator for that comparison.
What's excluded from this patio estimate?
Excavation and grading, a gravel base layer, edge forms, control joints, and any footings for an attached structure aren't included. It's material plus finishing labor for the flatwork itself.
How much more does a stamped or colored patio cost?
Stamping, coloring, and sealing roughly double finishing labor compared to a plain broom finish — see the Stamped Concrete Cost Calculator, which uses the same footprint math with a higher labor rate to reflect that.
What depth should a patio slab be?
4 inches is standard for a patio that only carries foot traffic and light furniture. If the patio will support a hot tub, heavy planters, or vehicle access, increase the depth and consider reinforcement.
Does patio size affect the cost per square foot?
Yes — smaller patios carry proportionally more forming and setup labor per square foot than large ones, since crew mobilization and edge work don't scale down with area. Treat the default rate as a mid-size average rather than a fixed number for every footprint.
