Use a sketch first

Mark the dimensions you measured and the products you selected before calculating.

Check the basis

Keep product dimensions, bag yield, and supplier conversions tied to their source.

Continue with a tool

Use the calculator directory to match your sketch to a transparent material takeoff.

Concrete per post reference

This narrow comparison uses a 12 inch diameter cylindrical hole, no post displacement, no gravel base, no waste allowance, and a selected bag yield of 0.45 cubic feet. Actual projects must use their own approved hole dimensions and the yield printed on the selected product.

Concrete depth	Exact volume	Whole bags
24 in	1.571 ft³	4
30 in	1.963 ft³	5
36 in	2.356 ft³	6

Download the reference as CSV. For different dimensions, displacement, gravel, waste, or bag yield, use the post-hole concrete calculator and inspect the formula methodology.
