How It Works
Concrete Calculator Pro is designed to take the guesswork out of construction projects. Instead of manually crunching numbers, the app provides fast, accurate, and professional-grade results in just a few taps.
Start by selecting the type of structure you’re working on: slab, footing, column, wall, or steps. Enter the dimensions, and the app instantly calculates the required concrete volume, factoring in your chosen unit system (metric or imperial). For walls, you can even account for openings such as windows or doors, ensuring precision.
Next, the app converts those volumes into bag counts (80 lb, 60 lb, 40 lb, or 25 kg bags), with costs automatically updated based on your input pricing. You can also include truck delivery costs or yard/m³ pricing for larger jobs. Adjustable waste percentages let you plan realistically, avoiding costly underestimation.
