Concrete Calculator

How It Works

Math is hard enough; take a load off and use our free concrete calculator to quickly calculate how much you'll need. Calculate based on numerous types of dimensions and an unlimited number of each.

What makes our calculator unique is the ability to add multiple shapes & dimensions in one sweep. Concrete projects are rarely just a single, clean slab. Here, you can calculate everything at once.

Tip:Your calculations will be saved automatically, so no need to worry about your progress being erased.

Let's get calculating!

Step-by-Step Tutorial

Calculating how much concrete you need has never been easier. Follow these 3 simple steps to make the process seamless and efficient. Let's get started!

Step 1: Choose Your Settings

Select your unit type, cost type (by bag or by the yard/meter), bag size, cost and desired waste amount. Your settings will be automatically saved for when you come back the next time.

By default, we start you with 80 lb. bags, assuming you're not using ready-mix concrete. You can adjust this number to match whatever bag size you plan to use.

Step 2: Choose Your Shape(s)

We understand that many projects require multiple shapes or dimensions. Choose from a slab, footing, column, stairs, curb/gutter, circle/tube or any combination of them—it doesn't matter how many you have, we'll do the heavy lifting.

Step 3: Add Your Dimensions

Once your shapes are added, input the dimensions that you've measured for each of them. After that, your results will be shown!

Pretty easy, isn't it?

Edit, Save and Repeat

Now you can easily measure all of your concrete projects. Bookmark this page and your calculations will be here when you return. When you're done, reset the calculator and start with a fresh one.
