Pick a shape, type the measurements in feet and inches or metric, and watch the volume update live as you go. Bags, Cost & Trucks See how many 60 lb, 80 lb, or 50 kg bags you need, what the load costs at your local rate, and whether to bag it by hand or order a ready-mix truck.

What can the Concrete Calculator work out? +

Pour calculates concrete volume in cubic yards, the number of bags, estimated cost, and whether to bag it or order a ready-mix truck, for slabs, footings, columns, and walls.

Is it free? +

The slab calculator is free. A single one-time Pour Pro purchase unlocks footing, column, and wall shapes, bag counts, cost estimates, and truck guidance. No subscription.

Does it work offline? +

Yes. Pour runs entirely on your device with no login or account, and your dimensions and prices are never tracked or uploaded.

Does it support metric units? +

Yes. You can work in imperial (feet and inches) or metric (meters and centimeters).

Which bag sizes does it calculate? +

It estimates counts for 60 lb, 80 lb, and 50 kg bags, and flags large pours over 50 cubic yards where a ready-mix truck makes more sense.
