Concrete & Volume Calculators

Concrete & Volume Calculators for Slabs, Footings & Fill

Ordering the right amount of concrete or fill material saves money and prevents project delays. Our concrete and volume calculators handle the most common shapes — slabs, footings, columns, steps, and free-form volumes — and convert results to cubic yards, cubic feet, and cubic meters. The concrete calculator supports multiple sections so you can combine a slab, footings, and piers into a single order. It calculates bag counts for 60, 80, and 90 lb bags and applies a configurable waste factor. The gravel and fill calculator estimates cubic yards and tons for gravel, sand, topsoil, and crushed stone with truckload and cost breakdowns. The general volume calculator handles cylinders, cones, gables, and other construction shapes. All tools accept input in feet-inches-fractions or decimal and display results with the precision you need for accurate material ordering.
