Concrete Calculator

The concrete calculator is a tool that helps you determine the approximate volume, thickness and weight of concrete required to cover a specific area. By providing the necessary inputs, you can obtain an estimation that will assist you in planning your concrete purchase. Consider acquiring a slightly higher amount of cement, flag thickness or volume of concrete than the estimated result to minimise the risk of running out of cement during your project.

Determining the right amount of ready-mix concrete you need for your project can be challenging, especially if you're new to using it. We take pride in offering our ready-mix concrete calculator, designed to simplify those initial steps.

We provide a complimentary quotation service once the calculations have been made to assist you further. If you have any uncertainties regarding the accuracy of calculating your width, height total length, or depth measurements, our team at Mixit is readily available to guide you through the process.

Our dedicated team has developed a useful concrete calculator to ensure you obtain the precise concrete required for your specific project.

To work out the Cubic area of material needed just enter the dimensions and unit type of the area to be filled then click the calculate button. The calculated amount is always rounded UP to the nearest M³ of readymix concrete.

Why correct concrete calculation is important

  • Correctly calculating the amount of concrete needed for a project is not only important for the success of the project, but it can also have a positive impact on the environment. Using too much concrete can result in unnecessary waste, which in turn leads to increased carbon emissions and other negative environmental effects.

  • When concrete is produced, it requires a significant amount of energy and resources. This includes extracting raw materials, transporting them to the production facility, and manufacturing the concrete itself. When more concrete than necessary is used on a project, the end result is an increase in the amount of energy and resources required to produce the excess material.

  • Furthermore, excess concrete often ends up in landfills, where it can take centuries to fully degrade. This means that the negative environmental impact of using too much concrete extends far beyond the initial construction phase of a project.

  • By accurately calculating the amount of concrete needed for a project, builders can reduce waste and minimise the negative environmental impact of their work. This not only benefits the environment, but it can also lead to cost savings for the builder and their clients.

  • In short, taking the time to properly calculate the amount of concrete needed for a project is an important step towards achieving sustainability in the construction industry.

Concrete volume and how to calculate how much you need

Concrete volume refers to the amount of space that will be filled by the concrete in a construction project. This calculation is important because it determines the amount of materials needed to complete the project and helps ensure that the concrete is mixed and poured correctly.

To calculate the concrete volume for your project, you must first determine the dimensions of the area that requires concrete. This can be done by measuring the length, width, and depth of the space in question. Once these measurements have been taken, multiply the length by the width by the depth of the area to find the total volume in cubic feet.

For example, if you are pouring a 10-foot by 10-foot foundation with a depth of 4 inches, the calculation would be:

10 ft x 10 ft x 0.333 ft (4 inches converted to feet) = 33.33 cubic feet

It's important to note that this calculation assumes that the area in question is a perfect rectangle. If the area has an irregular shape, the calculation will need to take into account the unique dimensions of the area.

Once you have calculated the concrete volume, you can use this information to determine the amount of concrete needed for the project. This is typically measured in cubic yards, so the final step involves dividing the cubic feet by 27 (the number of cubic feet in a cubic yard).

For example, using the previous calculation:

33.33 cubic feet / 27 = 1.23 cubic yards

This means that for the 10-foot by 10-foot foundation with a depth of 4 inches, you would need approximately 1.23 cubic yards of concrete.

How to decide which type of concrete you need for your project

Choosing the right type of concrete is crucial for ensuring that your construction project meets its specific needs and requirements. When it comes to selecting the appropriate type of concrete, there are several factors to consider, including strength, durability and finish.

Here's a brief overview to guide you in the right direction:


The strength of concrete is typically measured in PSI (pounds per square inch). A higher PSI indicates that the concrete is stronger and more durable. If you're working on a project that requires high-strength concrete, such as a bridge or a high-rise building, you'll want to opt for a mix that has a PSI rating of at least 4,000.


When considering durability, it's important to take into account the environment in which the concrete will be used. For example, if you're pouring a driveway in an area with harsh winters, you'll want to select a mix that's resistant to freeze-thaw cycles. Alternatively, if you're pouring a foundation in an earthquake-prone region, you'll want to choose a mix that has a high ductility factor to ensure that it can withstand seismic activity.


The finish of concrete refers to its appearance once it has dried and cured. There are a variety of finishes to choose from, including smooth, stamped, exposed aggregate, and broom. The finish you choose will depend largely on the aesthetic you're looking to achieve. For example, if you're pouring a patio, you may want to opt for a stamped concrete finish to mimic the look of natural stone.

In summary, when choosing the right type of concrete for your project, it's important to consider factors such as strength, durability, and finish. By taking these factors into account, you can ensure that your construction project meets its specific needs and requirements.


How to use our concrete calculator

paddingUsing our concrete calculator is a straightforward process. Here's a step-by-step guide on how to use a concrete calculator:

  • Determine the project details:

    Gather the necessary information about your project. Identify the area that needs to be covered with concrete, such as a round slab, full concrete slab top, concrete slabs, concrete footing top, concrete slab top, or column. Note down the dimensions required for the calculation, including length, width, and depth.

  • Input the project measurements:

    Open the concrete calculator and locate the input fields. Enter the dimensions of your project, such as the length, width, and depth, in the appropriate units of measurement (e.g., in a cubic yard, cubic metre, cubic feet each, metres, feet, inches). Some calculators may also ask for additional information, such as the shape of the walls in the area or the type of concrete mix.

  • Calculate the results:

    Once you have entered all the required dimensions and measurements, click on the "Calculate" or "Estimate volume" button provided by the calculator. The calculator will process the input and generate the estimated volume of concrete required for the final strength, volume and structure of your project.

  • Review the results:

    The concrete volume calculator will display the estimated volume of concrete in cubic feet or units of volume (e.g., in cubic feet, cubic yards, hundred feet or cubic metres) and may also provide an approximation of the number of bags or truckloads of cement needed. Take note of these results for your reference.

  • Adjust as needed:

    If you have specific requirements or the calculator offers customization options, you can adjust accordingly. For example, you might need additional cubic feet more of depth between columns or more cubic feet more of concrete to accommodate waste, extra thickness, or specific project considerations. Make the necessary changes in the calculator and recalculate the results.
