With just a few easy steps, you can quickly determine the exact number of cubic yards needed for your concrete project. Whether you have various shapes or need to calculate for a number of different slabs, our app is equipped to handle it all. Let's start calculating!

Step-by-Step Tutorial

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

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.

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.

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.

Formula for Concrete Yards

For those who like to do the math by hand, or are curious as to how it's done, below is the formula used:

The Formula: (Length x Width x Thickness) ÷ 27

How To Calculate Concrete Yards

Measuring a yard of concrete is surprising simple. It involves measuring the length, width and thickness of the slab (other shapes will require a different formula). As you've likely already seen, you can use our handy yard calculator above. If you still want to do it by hand, you can use the steps below. Let's begin!

1. Length: Measure the length of your slab.
2. Width: Similar to above, measure the width of the slab.
3. Thickness: This will be how thick you want your slab to be. It will likely be around 4 inches.

That's it! Now, you can take those measurements and plug them into the formula above and you'll have your estimations.
