About Concrete Calculator

gives homeowners, contractors and DIY builders a fast, accurate way to estimate concrete for any project, from a single patio to a full foundation. The goal is simple: help you order the right amount of material, cut waste, and plan a pour with confidence.

What we do

We build free calculators for slabs, footings, columns, bags, walls, stairs, curbs and more, and we pair each one with a plain guide that shows the formula and a worked example. Every tool reports results in the units suppliers actually use, cubic yards and cubic meters, along with bag counts, weight and a cost estimate.

Who is behind the site

is run by Best Concrete Calculator, based in online. The content is written and maintained by the Best Concrete Calculator team, who has hands on experience estimating concrete for construction projects.

How we keep the figures accurate

Our formulas and material values come from recognized sources, including manufacturer data sheets such as Quikrete, standards from the American Concrete Institute and ASTM, the Portland Cement Association, and building code references. We review the calculators and content on a regular schedule and update them when standards or figures change. You can read more on our Editorial Standards page.

Our limits

The tools give estimates for planning. They do not replace a licensed engineer, architect or your local building department, especially for structural or load bearing work. See our Disclaimer for the full statement.
