Because the cost of a cubic yard of concrete has topped $100.00 dollars per yard in a lot of areas around the U.S., it's helpful to know the exact cost in your area. The slab you see us pouring below used 120 yards of concrete. The cost per cubic yard of 3000 psi concrete for this slab was $92.00 dollars. That's $11,040.00 just for the concrete! The cost for a yard of concrete will vary in different parts of the country and all over the world.
50/27 = 1.85 cubic yards. Once you determine how much material your job requires, add 10 percent to that final number to account for waste and spills. It is far better to spend the money on too much concrete than to spend even more money to get a little bit more. For the example above, you need approximately 2 cubic yards of ready-mix concrete. According to the NRMCA - Ready-mix Concrete Industry Data Survey, the average cost of concrete in 2014 was $98.23 per cubic yard, or $196.46 for the 2 cubic yards needed for 10x10 patio project listed above.
