Free Concrete Estimation Tool

Ordering too little concrete means a halted job, and ordering too much eats into your profits. Our free concrete calculator helps you quickly figure out exactly how much volume you need for slabs, footings, and foundations.

How to Use This Calculator

Input the length and width of the area in feet, and specify the desired thickness in inches. The calculator will handle the unit conversions for you.

  • Total Volume: Displayed in cubic yards, which is the standard unit for ordering ready-mix concrete from a truck.
  • 80 lb & 60 lb Bags: If you are doing a smaller pour (like a sidewalk or patio slab), we calculate exactly how many pre-mixed bags you'll need to buy from the hardware store.

Need a Detailed Sitework Estimate?

While a simple volume calculator is great for quick checks, a commercial concrete pour involves much more. You need to account for rebar, wire mesh, formwork, vapor barriers, curing compounds, and labor. Our specialized concrete estimators can provide a full, detailed takeoff for your entire foundation or sitework project.
