Bagged concrete is a nationally distributed product and its price barely moves between states. Ready-mix and labor are local, which is why only those lines carry the multiplier.

Ready-mix delivered in Florida runs roughly $136 per cubic yard, against a national average of $155. Orders under 5 cubic yards usually carry a short-load fee of about $75 on top, which is why a small pour costs more per yard than a large one.
Placing and finishing labor here runs about $3.07 per square foot for flatwork, reflecting a construction labor market about 10% below the national average. That covers screeding, floating, edging and jointing. The finishing is what separates a slab that lasts thirty years from one that crazes and spalls in five, and it is the half of the bill that moves when you change states.
Bagged concrete does not move. It is a nationally distributed product priced at about $6.50 for an 80 lb bag anywhere in the country, so the state multiplier in this concrete calculator applies to ready-mix and labor only. Bought that way, a cubic yard costs $293, close to double the delivered rate in Florida.
The size most people arrive with is 20 × 20. At 4 inches thick that is 5.43 cubic yards including the 10% waste allowance, which in Florida works out to about $739 of delivered concrete plus $1,229 in placing and finishing labor, roughly $1,968, or $4.92 per square foot.
Scaling up and down from there: a 10 × 10 shed pad takes 1.36 yards and is the largest slab most people should attempt to pour themselves, while a 30 × 40 garage floor takes 16.30 yards and comes to around $5,905 in Florida before base preparation. Note that the per-square-foot figure barely moves between them. Concrete is one of the few trades where there is little economy of scale, because the material is the material.
None of those figures include a gravel base, forms, reinforcement, excavation or grading. The base is the one worth budgeting for immediately: 4.94 cubic yards of crushed stone under that 20 × 20 slab costs $200 to $600 installed, and it does more to prevent cracking than any other money you can spend.
Volume decides this, not price. Bags are always the dearer way to buy concrete. Below roughly 2 cubic yards they win on convenience: no delivery window to meet, no short-load fee, and you mix at your own pace over a weekend. The 1.36-yard shed pad above sits comfortably inside that, at 62 eighty-pound bags.
Above it the labor becomes the problem rather than the cost: at 2 cubic yards you are mixing 90 eighty-pound bags, and batches mixed at slightly different consistencies cure to different strengths. A truck arrives uniformly mixed and is placed in one go, with no cold joints where one batch met the next.
Set the state to Florida in the bag concrete calculator above and both routes are priced side by side for whatever you are pouring, with the local ready-mix and labor rates applied and the bag prices left national.
Florida has no meaningful frost depth requirement at all, which keeps post and footing costs down. Anything carrying load, a footing, a deck pier, a fence post, has to bear below that line, because a footing that stops short of it will heave and heave cracks whatever sits on top. A 12-inch column form taken to 12 inches holds 0.8 cubic feet on its own, which is how frost depth turns into a concrete order.
Ground conditions here are sand over limestone, which drains fast but offers limited lateral support for posts. That affects both how hard the excavation is and how much base a slab needs underneath it, 4 inches of compacted gravel is the standard specification and 6 inches the usual answer over clay or poorly draining subgrade, at $30 to $50 per delivered cubic yard.
Sandy soil means posts need more concrete for lateral resistance, and hurricane-zone footings are often specified deeper and wider than code minimum elsewhere. The climate here is hot, humid and subtropical, with a defined hurricane season, and concrete is sensitive at both temperature extremes: below about 40°F it gains strength too slowly and needs blankets or a heated enclosure, and above about 90°F it can flash-set and crust before it has been properly finished.
Every figure on this page comes from the same open formula the calculator above uses. Volume is pure geometry, the shape's formula worked in feet, plus a 10% waste allowance. Prices start from 2026 national baselines: $155 per cubic yard delivered, a $75 short-load fee under 5 yards, retail bag prices against the yields QUIKRETE and Sakrete publish, and $3.50 per square foot for placing and finishing flatwork. Ready-mix and labor are then scaled by the construction earnings multiplier the Bureau of Labor Statistics publishes for your state; bagged concrete is not, because it is priced nationally. Nothing is hidden behind a lead form and no supplier pays to appear here. What the result is not is a quote: excavation, base preparation, forms, reinforcement, permits and demolition are excluded, and a plant will price your delivery distance and mix specification on top.
Ready-mix delivered in Florida runs about $136 per cubic yard against a national average of $155, reflecting a local construction labor market at 0.88× the national rate. Orders under 5 cubic yards add a short-load fee near $75. As of July 2026, ready-mix prices sit about 9% above their five-year average on the Producer Price Index, so a quote you were given a couple of years ago understates what a plant charges today. Bagged concrete is priced nationally and barely varies by state. An 80 lb bag is about $6.50 anywhere in the country, which works out to $293 per cubic yard.
A 20 × 20 slab is 400 square feet and needs 5.43 cubic yards at 4 inches thick including waste. In Florida that is roughly $739 in delivered ready-mix plus about $1,229 in placing and finishing labor, around $1,968 all in, or $4.92 per square foot. Add $200 to $600 for a compacted gravel base, plus forms, reinforcement and any grading. Pouring it yourself removes the labor line entirely and leaves the $739 of concrete.
A 30 × 40 slab at 4 inches thick is 1,200 square feet and takes 16.30 cubic yards including the 10% waste allowance. In Florida that is about $2,218 of delivered concrete and roughly $3,688 in placing and finishing labor, for a total near $5,905 before base preparation and reinforcement. At this volume bags are not a serious option. It would take 734 eighty-pound bags, about 29 tons of material.
Cheaper, yes. The question is whether the slab is small enough. Placing and finishing labor in Florida runs about $3.07 per square foot, which on a 20 × 20 slab is $1,229 of a roughly $1,968 project. Doing it yourself leaves $739 of ready-mix, or $1,593 if you buy 245 eighty-pound bags instead. Below about 2 cubic yards, a shed pad like the 10 × 10 above, at 1.36 yards, that is a realistic weekend. Above it you are racing the set time rather than the budget, and that is the point at which hiring a crew stops being optional.
Yes, and in Florida the reason is specific: ground conditions here are sand over limestone, which drains fast but offers limited lateral support for posts. A 4-inch compacted gravel base under a slab gives uniform bearing, breaks the capillary path that wicks groundwater into the concrete, and gives water a route out. Where the subgrade is clay or drains poorly, 6 inches is the usual specification. On a 20 × 20 slab that is 4.94 cubic yards of crushed stone, or $200 to $600 installed at $0.50-$1.50 per square foot.
Florida has a typical frost depth of 0 inches, and any footing carrying load has to bear below that line so a freeze cannot lift it. With no frost requirement, footing depth here is set by soil bearing capacity and wind uplift rather than freezing, which keeps the concrete volume down. Deck piers are the most common reason a homeowner pours footings, and our deck calculator prices the structure they carry.
Volume decides it, not price. Bags are always the dearer way to buy concrete. Below roughly 2 cubic yards bags win on convenience: no delivery window, no short-load fee, and you mix at your own pace. Above that, mixing becomes the problem rather than the cost, because 2 yards is 90 eighty-pound bags and batches mixed at different consistencies cure to different strengths. Ready-mix in Florida costs around $136 per yard delivered against $293 a yard in bags.
Sandy soil means posts need more concrete for lateral resistance, and hurricane-zone footings are often specified deeper and wider than code minimum elsewhere. The climate here is hot, humid and subtropical, with a defined hurricane season, and concrete is sensitive at both temperature extremes: below about 40°F it gains strength too slowly and needs blankets or a heated enclosure, and above about 90°F it can flash-set and crust before it has been properly finished. Aim for a mild, still, overcast day and start early; wind and direct sun pull water out of the surface faster than heat alone does.
