Concrete Calculators

Concrete volume, bags and cost — figure out the cubic yards, how many bags, and what a pour will cost.

CalcBooth’s concrete calculators turn slab, footing and column dimensions into the numbers you actually order with. The concrete calculator finds the volume in cubic yards and cubic feet and tells you how many 40, 60 or 80 lb bags it takes — or how much ready-mix to order. The concrete bags calculator focuses on the bag count for a job, the cost calculator prices a pour by the yard including delivery and short-load fees, and the dry-pour calculator sizes bags for the pour-and-soak method. Each tool adds a waste allowance and shows the formula it uses, so you can compare bagging it yourself against a ready-mix truck before you buy. Concrete figures are planning estimates — confirm exact quantities and pricing with your supplier before you order.
