Every calculator on ConcreteYard, grouped by category, with what it does and a direct link to use it.
Enter length, width, and thickness to get cubic yards, 80 lb bag count, and cost for any flat slab — patios, walkways, garage floors, and shed pads all use this same calculation.
A pure unit converter — turns length, width, and thickness into cubic feet, cubic yards, and cubic meters, useful when you already have dimensions and just need the yardage figure.
Sized specifically for backyard patio pours: enter your patio's footprint and 4in default thickness to get cubic yards, bags, and cost.
Built for long, narrow pours — walkways and sidewalks — using the same slab formula but tuned for typical 3–5 ft widths and municipal sidewalk standards.
Sums the stacked volume of a concrete stair pour from width, rise, run, and step count — handles the compounding volume of each step correctly.
Sized for garage floor slabs specifically, with thickness guidance by vehicle type (standard car vs. workshop vs. RV/heavy load).
Sized for basement floor slabs, factoring in the standard gravel-and-vapor-barrier build-up beneath the concrete layer.
Counts standard 8x16in CMU blocks needed for a wall from its length and height, plus an estimate of mortar bags. Includes a waste factor for cuts and breakage at corners and openings.
Sizes a continuous footing or foundation trench pour from linear length, width, and depth in inches. Common footing sizes by structure type are included as a quick reference.
Calculates volume for any round form — sonotubes, deck footings, fence posts, columns — from diameter, height, and quantity, using the standard cylinder volume formula.
Sizes a poured (formed) concrete wall from length, height, and thickness, returning cubic yards, estimated weight, and cost. For CMU block walls, use the Block Calculator instead.
Estimates concrete for a poured retaining wall, with an optional standard footing included, plus guidance on when a wall needs an engineer's design.
Totals post count and concrete for an entire fence run from total length and post spacing — faster than calculating each hole individually.
Sizes a single post hole (mailbox, sign, one-off footing) from diameter and depth, with an optional deduction for the post's own volume.
Estimates how many footings a deck needs from its footprint and footing spacing, then totals the concrete for all of them combined.
Calculates a rebar grid's bar count and total linear footage from slab dimensions and on-center spacing, converted to standard 20-ft stick count.
Calculates concrete for a curb or curb & gutter run using preset cross-section profiles, multiplied by your total linear run length.
Calculates concrete for square or rectangular columns and piers (as opposed to round forms) from width, depth, height, and quantity.
Works out exactly how many 40, 60, or 80 lb bags of Quikrete, Sakrete, or any bagged mix you need for a project, plus total weight and cost. Best for pours under about a cubic yard.
Calculates crushed (recycled) concrete needed for driveway base, drainage fill, or backfill, in both cubic yards and tons, since most quarries price it by weight.
Splits a target concrete volume into cement, sand, and gravel by common mix ratios (1:2:3 and similar), with cement converted to standard 94 lb bag count.
Calculates bulk sand needed for a paver base, bedding layer, or fill area in cubic feet and tons, using standard sand bulk density.
Sizes a gravel sub-base for a slab or driveway from area and depth, in cubic yards and tons — a companion to the Crushed Concrete Calculator.
Converts any slab or pour's dimensions directly into total weight in pounds and tons, for normal-weight or lightweight mix.
A quick reference: pick a target PSI strength and see the typical mix ratio and common use case, from non-structural fill up to high-strength structural mixes.
Estimates walk-on, drive-on, and full-strength cure timelines based on your site's average temperature, since cold weather significantly slows concrete's hydration.
Estimates full driveway material cost from length, width, thickness, and your local price per yard, with optional finish upcharge and delivery fee — useful for sanity-checking a contractor's bid.
Turns a known cubic-yard figure into a full landed cost, including delivery, pump truck, and short-load fees — the tool to use once you already know your volume.
Bridges square footage and cubic yards — enter area and thickness to get volume, yardage, bags, and cost in one step.
Estimates full stamped concrete project cost — base material, stamp/color upcharge, and sealer — separately, since decorative finish pricing varies widely from plain concrete.
Sized for concrete countertop pours — typically 1.5–2in thick — with bag count output since most countertops use bagged mix rather than a truck order.
Calculates exact paver count needed to cover an area from paver dimensions, plus the base sand quantity for the leveling layer underneath.
