Select the area shape and enter its length, width, and height dimensions. The calculator will try to estimate the volume of concrete required to fill the area.
Estimate the volume and weight of concrete that you need to complete a construction project. It is a good option to use a little higher quantity of material to avoid any shortage issues on the job site.
Our concrete calculator will determine the concrete material quantity and cost to purchase it accurately. With that, the tool will also help you in calculating concrete bags subjected to different concrete weights.
Get calculations in different units of measurement to ensure precision.
| Component | Percentage |
|---|---|
| Cement | 10% |
| Air | 20% |
| Sand | 30% |
| Gravel | 40% |
It depends upon the type of project. Whether you are constructing a concrete slab, footings, steps, or columns, the amount of material will differ always. Using the concrete calculator can give you an instant estimation of the concrete that you require to complete your earthwork project.
The important aspect that is worth considering here is the shape of the area. Once you measure the dimensions of the land, it becomes easier to predict the cement material accordingly. But the situation holds until you are dealing with basic shapes like rectangles, squares, triangles, etc. When it comes to areas with irregular dimensions, the task becomes tricky.
In this situation, you can divide the area into smaller portions that match different basic geometrical shapes supported by concrete calculator provides calculations. After that, you can add up all small calculations and get the concrete volume for the overall land area.
When mixing or pouring concrete, chances are that some ratio of it may be wasted. This is why you should prefer making 5-6% extra concrete so you can complete your project without running out of concrete.

The tool works to give you instant outputs by considering certain related parameters that are necessary for the calculations. These include:
With our concrete slab calculator, you no longer have to deal with complicated calculations that are involved in estimations. The tool does the task very efficiently to give you precise values in less than a second.
For a 24x24x4 concrete slab, you need 0.59 cubic yards of concrete volume. The weight against this volume is about 958.5 kg.
General Mix:
| Concrete Type | Ratio |
|---|---|
| All In Ballast | 1:5 |
| Cement:Sharp Sand:Gravel | 2 ½:3 ½ |
Paving Mix:
| Concrete Type | Ratio |
|---|---|
| Cement:All In Ballast | 1:3 ½ |
| Cement:Sharp Sand:Gravel | 1:1 ½:2 ½ |
A normal concrete slab has a face of about 8 inches by 10 inches (203mm by 406mm). The available thickness in these sizes includes 4, 6, 8, 10, 12, 14, and 16 inches.
The strongest concrete material ratio is 1:2:3:0.5.
To get these estimations without any error involved, you can use the concrete bag calculator.
As calculated from concrete yard calculator, you need:
