Stay Informed: Homeowners must know how much concrete is required and what your contractors ask. Our concrete calculator helps to get clarity and make informed decisions.

Cost-Efficient: It’s free of cost and saves you money by giving you the correct estimate so no concrete is wasted during construction.

Hassle-Free: You do not have to do any long calculations. Just enter the data and get the answers. It’s simple and accurate.

Less Carbon footprint: Concrete mix calculators are essential to protect the environment. Wasting the concrete can increase land pollution and the carbon footprint generated during their production in factories.

How Does It Work?

It has two ways: you do it yourself, or we help you.

  • Choose the unit of measurement from the options available.
  • Add the accurate dimensions of your concrete form, such as the length, width and height.
  • To calculate the cost and amount of cement bags required per your project’s estimated concrete, enter the cost of each bag, its density, bag yield, and size.

Get the results!

We recommend ordering the concrete quantity 5-10% more than the estimated value to avoid inconvenience and for better project management. However, if unsure whether you did it right, call our experts! We can do it for you or even double-check your results!
