Concrete Cost Calculator: Price per Yard, Bag and Square Foot
Ready-mix concrete costs $160 to $195 per cubic yard (national range), so a 10×10 ft slab at 4 in costs about $218 to $265 in material with 10% extra.
Advanced options: waste, prices
NRMCA advises ordering 4 to 10 percent over the estimate.

How to Calculate Concrete Cost
Calculate concrete cost from volume and price.
- Find the volume in cubic yards with the calculator.
- Add 10% extra.
- Multiply by your ready-mix price per yard, or multiply the bag count by your bag price.
- Add delivery and short-load fees from your supplier's quote.
Concrete Cost by Project Size
Concrete cost for common slab sizes at 4 in is listed below, as concrete only and installed.
| Slab (4 in) | Sq ft | yd³ with 10% | Concrete only | Installed |
|---|---|---|---|---|
| 10×10 ft | 100 | 1.36 | $217–$265 | $650–$1,050 |

What Changes the Price of Concrete?
Three factors change the price of ready-mix concrete, according to Concrete Network.
- Mix strength: higher-psi mixes cost more per yard.
- Order size: small orders often carry short-load fees.
- Delivery distance: longer hauls cost more.
How Much Is a Yard of Concrete Right Now?
A yard of ready-mix concrete costs $160 to $195 in the 2026 national range from Concrete Network; this page is reviewed every 6 months.
Concrete Cost per Cubic Meter
Concrete costs about $209 to $255 per cubic meter at the same national range ($160–195 ÷ 0.7646).
Is Bagged Concrete Cheaper Than Ready-Mix?
Bagged concrete is cheaper only for small pours, below about 1 cubic yard (this calculator's own rule). Compare both with your prices on bagged concrete vs ready-mix.
Concrete Cost by Project Type
Each project type has its own cost guide with price per square foot and worked examples:
- Concrete sidewalk cost: price per square foot and by length.
- Stamped concrete cost: basic, mid-range and high-end price per square foot.
- Concrete retaining wall cost: poured walls per square foot of face.
- Concrete pool deck cost: simple, custom and elaborate decks.
- Concrete foundation cost: slab-on-grade and monolithic foundations.
- Concrete delivery cost: short-load and delivery fees.
- Concrete removal calculator: tons and loads of broken concrete.
Worked Examples: Cost of Three Pours
10×10 ft patio at 4 in. 1.36 yd³ × $160–195 = $217–$265 concrete; installed, $650–$1,050.
24×24 ft garage at 4 in. 7.82 yd³ × $160–195 = $1,252–$1,525 concrete; installed, $3,744–$6,048.
40×60 ft shop slab at 4 in. 32.59 yd³ (3 trucks) × $160–195 = $5,215–$6,356 concrete; installed, $15,600–$25,200.
Ready-Mix vs Bagged Cost
One cubic yard costs $160–195 as ready-mix, or 45 × your 80 lb bag price as bags; at $6.50 a bag, that is $293 a yard. See bagged concrete vs ready-mix.
How to Save on Concrete
- Measure carefully and order 4–10% extra, not more (NRMCA).
- Order the strength the code needs, not higher (IRC Table R402.2).
- Combine small pours into one delivery to avoid short-load fees.
- Prepare forms and base before the truck arrives.
