Estimate an order from geometry and product yield
- Add each slab, cylinder or round post hole. Choose units for each dimension and enter only the post depth actually inside the concrete.
- Set waste and finished volume per bag using your product label or an identified QUIKRETE example. Choose currency and enter optional unit price and delivery.
- Calculate total volume before rounding up bags. Review every area and supplier assumptions, then export the material estimate.
A slab with a waste allowance
10 ft × 10 ft × 4 in is 33.3333 ft³. With 10% waste and 0.6 ft³ per bag, buy 62 bags. At USD 6 each plus USD 20 delivery, the estimate is USD 392.
