Several online concrete calculators are available that help estimate the amount of concrete needed for various projects. These calculators typically work by allowing users to enter dimensions such as length, width, height or thickness, and shape (square, rectangle, circular sections, etc.) to calculate the concrete volume. They often provide the amount of concrete required in cubic yards, cubic meters, or number of bags. Many also recommend adding a margin (typically 5-10%) for waste and variations on site. Popular concrete calculators include:
- Holcim Ready Mix Calculator — lets you input multiple shapes and dimensions, adds a 5% margin, and provides volume estimates.
- ConcreteNetwork Calculator — trusted by millions, calculates cubic yards, meters, or bags for slabs, footings, and columns, with standard thickness references.
- MudMixer Concrete Calculator — estimates number of bags needed, suggests adding 5-10% margin, works for both small and commercial projects.
- QUIKRETE Concrete Calculator — estimates bags needed for different slab depths and mortar or fast-setting concrete products.
- Calculator.net Concrete Calculator — gives volume and weight estimates, covers various shapes like slabs, holes, stairs, and more.
