Estimate the total cost of a concrete slab. Enter the dimensions and the price per yard to get a realistic budget in seconds.
Material cost = cubic yards × price. Total adds a typical 50% labor premium. Your local labor rates will vary.
Ready-mix concrete runs about $125 to $150 per cubic yard delivered in most of the US, and labor roughly doubles the total. A 20 by 20 foot slab at 4 inches thick is 4.9 cubic yards, so the concrete is about $660 and the full poured slab runs $1,200 to $1,500.
What actually drives the price is thickness and access. A 4-inch patio is the cheapest pour. A 6-inch driveway costs 50% more in concrete. A slab in a hard-to-reach backyard adds a pump fee. Reinforcing with rebar or wire mesh adds a few hundred dollars but prevents cracks.
A 20 by 20 foot slab at 4 inches thick needs about 4.9 cubic yards. At $135 per yard for concrete and a 50% labor premium, expect $1,200 to $1,500 total.
Ready-mix concrete typically costs $125 to $150 per cubic yard delivered. Bagged concrete works out to more per yard, around $150 to $200.
No. The concrete itself is about half the cost. Labor, forms, grading and finishing roughly double the total for a professionally poured slab.
Thicker slabs, rebar or mesh reinforcement, a pump truck for hard-to-reach spots, and colored or stamped finishes all add to the price.
For a small pad, yes — you save the labor, which is half the cost. For a full driveway or large slab, the equipment and finishing skill usually make a contractor worth it.
