Concrete is a high compressive building material that is strong and durable. It is used in buildings of all kinds. Therefore, it’s essential for builders to correctly estimate the amount of ready mix concrete needed for building a particular structure. Pre-mixed concrete comes in different weights and has different densities.
A concrete calculator helps builders get an idea of the weight and volume of concrete required for a particular area.
For walls, slabs or square footings
The total area for which concrete is used is then furnished in cubic yards/cubic feet. It will also let you know how many 40, 60, or 80 pound bags of concrete you will require. As the calculator only gives an estimate of the amount of concrete needed, it’s always a good idea to buy a little more just in case you fall short.
Watch this video below where I shown you exactly how to use the paint calculator and explain what the calculation results mean.

Calculating the amount of concrete, you require can be tricky. Generally, multiply the length x width x depth will give you a quantity but you must consider how much waste there will be and if you will require more than the theoretical amount of concrete.
Concrete estimating is difficult as a lot of factors must be considered. If you are mixing the concrete yourself then this will take a lot of time compared to bringing in ready mix concrete and pumping it. Each scenario needs to closely analyzed to see what it entails to provide accurate costings.
Multiply the length x width x depth to get a meter cubec (m3) quantity. Then divide it by the size of the concrete dry premix bag which are generally around 0.01m3. This will give you the amount of bags you required.
