How to Estimate Concrete

Accurately estimating the amount of concrete needed is the first step in any concrete project. This calculator helps you determine the volume of concrete required for a rectangular slab, which is a common shape for driveways, patios, and foundations. Concrete is typically ordered in cubic yards or cubic meters. It's always a good idea to order slightly more (around 5-10%) than your calculated amount to account for uneven subgrade, spillage, and formwork variations.
