Cost Estimate for 5'x5' x6"

Purchasing ready-mix concrete is by far the easiest way to mix concrete for medium to large projects and can even be used on smaller projects as well. We have provided a cost comparison between ready mix and DIY concrete premix bags to give you a rough ballpark estimate.

Bag Cost Estimate

Pre-mixed concrete bags cost on average $3.50 per 80lb bag. Using pre-mixed bags to cover 25 sq ft at a depth of 6", the estimated cost is $72.80
for 20.8 x 80lb bags

Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered.

Most concrete truck companies have a 1 to 4 cubic yard minimum order. We recommend contacting your nearest concrete suppiler for an estimate. So for this estimate the 1 yard minimum will be used.

Concrete trucks may also charge a "short load" fee for partially filled loads. Short load fees are charged at about $17 for every yard not used on the truck.

So for a 10 cu/yd Truck Load - 1 cu/yd of concrete = 9.00
9.00 x $17.00 = $153.00
$153.00 + $108.22 = $261.22
(1 cubic yard)

Concrete Extras

A well-compacted subbase provides a strong foundation for concrete to lay on. We recommend you contact your nearest concrete supplier for their recommendations on whether you need a subbase, base depth, and rock type.

With a brief look, a 5x5 area at 6 inches deep, you would need approximately 0.66 tons or 0.46 cubic yards of gravel.

Concrete reinforcing is also recommended in high traffic areas and medium to large areas. Wire mesh on average costs $0.56 per sq ft and fiber mesh costs $0.13 per sq ft.

So for your 25 sq ft area, this may roughly cost $14.00 for wire mesh, $75.00 for thicker wire rebar mesh and $3.25 for fiber mesh.

*Reinforcing for 10 inch pours and under.
How to Calculate Concrete Amount for 5x5 x6"
5 * 5 = 25 sq ft
6 / 12 = 0.5 ft depth
25 * 0.5 = 12.5 cu ft
12.5 / 27 = 0.46296296296296
= 0.463 cu/yd
How to Calculate Concrete Weight
0.46296296296296 * 3590 = 1662.04 lbs
Density of concrete used 2130 kg/m3or 133 lbs/ft3.

5 ft x 5 ft x 6" Concrete Summary

How much concrete do I need for an area of 5 ft x 5 ft x 6" depth? 0.463 cu. yds.
How many concrete bags would I need for a 5 ft x 5 ft x 6" slab? 20.8 x 80lb Concrete bags.
How much does it cost to pour a 5'x5' x6" slab? Ready-mix costs approx $211.60.
How do you calculate concrete volume? Formula ((width x length) x (depth in inches / 12)) / 27 = total cubic yards. See our how to here
