Concrete Calculator

By Palawin Yosintra

Open iTunes to buy and download apps.


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".

Home builder

Works great, for guy who can't read and left 1 star, it clearly says radius not diameter. A 10' sonotube with 24" (12") radius requires 1.16 yrds. If you input 24" radius (4' diameter) THEN it's over 4 yrds.

Pay attention to what you input and you will get correct results. Great time reducing app for on the fly figures.

Incorrect Computations

I'm pretty sure it doesn't take over 4 cubic yards of concrete to fill a 24" diameter by 10 Ft deep sonotube pier hole. But this app says it does. Inaccurate results are being given. What good is this app if it doesn't give accurate measurements??? Needs improvement.


Some results are kinda inaccurate, but very good idea.
