Concrete Calculators
Calculate concrete volume, bags, and cost for slabs, footings, columns, and more.
Concrete is sold by the cubic yard for ready-mix orders and by the bag for small DIY pours. The calculators below handle both: enter your dimensions and get cubic yards for truck delivery or the exact number of 60lb and 80lb bags from the hardware store. All formulas follow ACI 318 standards with a built-in 10% waste factor so you don't run short mid-pour.
