Concrete Footing Calculator
Cubic yards for strip and pad footings from length, width and depth.
Concrete Block Calculator
CMU block and mortar bag counts for walls by length and height.
Rebar Calculator
Rebar bar count, linear feet and weight for slab grids by spacing.

When to use which calculator
The Concrete Calculator answers the universal question — how many cubic yards — with bag counts included. Use the Bag Calculator for small DIY pours, the Ready Mix Calculator when ordering trucks, and the shape-specific tools (footings, columns, block walls) when the pour isn't a simple slab. The Rebar Calculator handles the steel inside it.
