Concrete Cost Calculator

This concrete cost calculator gives a planning range for a slab, patio or pad; see our concrete installation guide for what drives the price. Get a planning range for a concrete slab, patio or pad. Material cost comes from the cubic yards required and your price per yard; labor is estimated per square foot. The defaults come from national cost data (ready-mix $137/yd³; labor $2–$5 per sq ft) — replace them with local quotes for a better estimate.

Results from this concrete cost calculator are planning estimates; confirm quantities and prices with your supplier or contractor before you order.

How to use the concrete cost calculator

  2. Enter your supplier's price per yard.
  3. Adjust the labor range to quotes from local finishers.
  4. Add extras such as removal of an old slab, forms or reinforcement.

Formula

Total = (cubic yards × price per yard) + (area × labor per sq ft) + extras. Shown as a low–high range.

Worked example

A 20 × 20 ft patio at 4 in: 5.19 yd³ × $137 = $711 material; labor 400 × $2–$5 = $800–$2,000; total about $1,510–$2,710 before extras.

Tips for using the concrete cost calculator

  • Get your local ready-mix price per yard; it varies widely by region and season.
  • Add removal of old concrete, base gravel and rebar if your project needs them.
  • Decorative finishes such as stamping or staining can double the per-square-foot labor.
