The "Concrete Calculator" is good for building, construction or DIY. It is very quick and easy to use.

It provides you choices of concrete calculation for...

✔ Square or Rectangle Concrete Slab,

✔ Circular Concrete Slab,

✔ Concrete Sono Tube or Column.

If you have concrete delivered (as it is sold by the yard), the "Concrete Calculator" helps you calculating the amount of cubic yards of concrete required and total cost.
If you do not have concrete delivered, we also give you a choice to calculate number of 60 lb. or 80 lb. bags of concrete required.
In addition, the "Info" tab provides you the calculation method for your reference.


We have verified the calculations and formulae as correct, yielding good results.

Please make sure to enter "Radius", not "Diameter".
