Concrete Cost Calculator

How It Works

Take the hassle out of math and simplify your concrete planning with our free concrete cost calculator.

With just a few easy steps, you can quickly determine the exact amount of concrete needed for your concrete project and how much it'll cost. 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 much your concrete project will cost 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.

Estimating the Cost of Your Concrete Project

Whether you're planning on pouring a patio, sidewalk, A/C pad or even an entire driveway, knowing the cost upfront can help you budget effectively and avoid any surprises. 

Here's how you can estimate the cost of your concrete project based on the number of bags, cubic yards, or project square footage.

1. Cost Based on Number of Bags

First, calculate the number of concrete bags required as outlined in the previous section. Once you have the number of bags, follow these steps to estimate the cost:

• Determine the Price per Bag: Check local suppliers or home improvement stores for the current price of concrete bags. Prices can vary, but an 80-pound bag typically costs between $4 and $6.
• Calculate the Total Cost: Multiply the number of bags by the price per bag.

Total Cost = Number of Bags × Price per Bag

For example, if you need 19 bags and each bag costs $5:

Total Cost = 19 × 5 = $95

2. Cost Based on Cubic Yards

For larger projects, concrete is often measured and priced by the cubic yard. Here's how to estimate the cost:

• Calculate the Volume in Cubic Yards: First, convert your project's volume from cubic feet to cubic yards by dividing by 27 (since 1 cubic yard = 27 cubic feet).

Volume (cubic yards) = Total Volume (cubic feet) / 27

For example, if your project requires 10 cubic feet of concrete:

Volume (cubic yards) = 10 / 27 ≈ 0.37 cubic yards

• Determine the Price per Cubic Yard: Prices can vary widely based on your location and supplier, but generally range from $100 to $150 per cubic yard.
• Calculate the Total Cost: Multiply the volume in cubic yards by the price per cubic yard.

Total Cost = Volume (cubic yards) × Price per Cubic Yard

For example, if concrete costs $120 per cubic yard:

Total Cost = 0.37 × 120 ≈ $44.40

3. Cost Based on Project Square Footage

For projects such as patios or sidewalks, estimating costs based on square footage can be straightforward:

• Measure the Area: Calculate the total square footage (Length × Width).
• Determine the Thickness in Feet: Convert the desired thickness from inches to feet (e.g., 4 inches = 0.33 feet).
• Calculate the Volume in Cubic Feet: Multiply the area by the thickness.

Volume (cubic feet) = Area (square feet) × Thickness (feet)

For example, for a 10' × 10' patio at 4 inches thick:

Volume=10 × 10 × 0.33 = 33 cubic feet

• Convert to Cubic Yards: Divide by 27 to convert cubic feet to cubic yards.

Volume (cubic yards) = 33 / 27 ≈ 1.22 cubic yards

• Determine the Price per Square Foot: Some contractors may provide a price per square foot, including labor and materials. This can range from $8 to $12 per square foot.
• Calculate the Total Cost: Multiply the area by the price per square foot.

Total Cost = Area (square feet) × Price per Square Foot

For example, at $10 per square foot:

Total Cost = 100 × 10 = $1,000
