14×14 concrete slab: what to expect

A 14×14 slab covers 196 square feet. At the standard 4" thickness it takes about 2.66 cubic yards of concrete once you allow 10% for waste, which is roughly 120 × 80 lb bags if you mix by hand. Stepping up to 6" — sensible if it'll carry a vehicle — raises that to about 3.99 cubic yards.

Budget around $1,078 – $2,352 to have a 4" slab this size poured and finished by a contractor, or roughly $393 – $681 in ready-mix if you're doing the labor yourself. On top of the concrete you'll need about 2.78 yd³ of gravel base and 14 sticks of rebar.
