Planning a concrete project can be tricky — order too little, and you’ll run short midway; order too much, and you’ll overspend. Our Concrete Calculator takes out the guesswork by helping you quickly estimate the concrete volume, number of mix bags, and overall cost required for your slab, wall, column, or footing. Whether you’re a contractor, builder, or DIY enthusiast, this free tool ensures your project is well-prepared from the start.
The online concrete estimator is simple to use and provides instant, reliable results for any shape or size. Follow these easy steps to calculate your requirements:
Our Concrete Volume Calculator uses precise mathematical formulas for different shapes to ensure you get accurate measurements every time.
Volume = Length × Width × Thickness
Ideal for driveways, patios, and floor foundations.
Volume = π × (Diameter / 2)² × Height
Used for columns, circular footings, or round patios.
Volume = Length × Height × Thickness
Commonly used for foundation walls or retaining structures.
Volume = π × (Diameter / 2)² × Depth
Best for deck posts, fence supports, or pillar bases.
When using pre-mixed concrete, our calculator also tells you how many bags you’ll need based on your total volume. Below are approximate yields for standard bag sizes:
The calculator divides your total volume by the yield per bag and rounds up automatically to ensure you always have a little extra for leveling, spillage, and variation in mix density.
Yes, it’s smart to order about 5–10% more than your estimated volume. This covers any measurement variations or waste during pouring.
Absolutely. Just input your local concrete rate per cubic meter or per bag to get an approximate total cost instantly.
No — cement is just one ingredient in concrete. Concrete is made from a mix of cement, sand, gravel, and water, forming a strong and durable building material once it hardens.
Yes! Our tool is completely free and doesn’t require any registration, subscriptions, or hidden payments.
The Concrete Calculator makes project planning fast, accurate, and worry-free. From small DIY patios to large foundations, you can calculate exact concrete volume, number of ready-mix bags, and estimated costs in just seconds. Save time, reduce waste, and pour with confidence using our simple online concrete estimation tool.
