This calculator estimates how much concrete a slab, footing, or column needs and what it will cost. Concrete is sold by volume (cubic yards or cubic meters), so the job is to convert your dimensions into volume, then multiply by the price.
Volume = Length × Width × Depth; Cost = Volume × Price per unit volume
Length, width, and depth must be in consistent units; depth is often in inches and should be converted to the same unit (feet or meters) as length and width. Volume is then converted to cubic yards or meters for pricing.
Always add a waste allowance (commonly 5–10%) for spillage, uneven subgrade, and over-excavation — ordering exactly the calculated amount usually leaves you short. Concrete is far cheaper to slightly over-order than to do a second pour.
