🧱 Concrete Calculator
Calculate how much concrete you need in cubic yards and number of bags.
How to Calculate Concrete Needed
For slabs, multiply length × width × depth (in feet) to get cubic feet, then divide by 27 to get cubic yards. A standard 60-lb bag covers about 0.45 cubic feet, while an 80-lb bag covers about 0.6 cubic feet. Always order 5-10% extra for waste.
