Concrete Bag Yield Chart: 40, 60, 80 lb Bags

A concrete bag yield chart shows how many cubic feet one bag makes after mixing. Yield is the number behind bag counts, square-foot coverage, pallet coverage, and ready-mix comparisons.

Use the Concrete Bag Calculator for exact bag counts, the Concrete Quote Reviewer for bid comparison, and the Concrete Proposal Kit for client-ready material line items.

Competitor pages such as ConcreteCalculatorMax's concrete bag coverage and yield guide and ConcreteCalculator.pro's concrete bag calculator serve bag-yield intent. This page gives a compact yield-first chart connected to buying, pallet, and quote decisions.

Quick answer

Common planning yields are:

Bag size	Common yield	Cubic yards per bag	Bags for 1 yd3 before waste
40 lb	about 0.30 ft3	0.011 yd3	about 90
60 lb	about 0.45 ft3	0.017 yd3	about 60
80 lb	about 0.60 ft3	0.022 yd3	about 45

Always confirm the yield printed on the exact bag you plan to buy. Specialty mixes can vary.

Yield formula

cubic yards per bag = bag yield cubic feet / 27

bags needed = project cubic feet / bag yield cubic feet

Then add waste and round up to whole bags.

Coverage by thickness

Bag size	3 in thick	4 in thick	5 in thick	6 in thick
40 lb	about 1.2 sq ft	about 0.9 sq ft	about 0.7 sq ft	about 0.6 sq ft
60 lb	about 1.8 sq ft	about 1.35 sq ft	about 1.1 sq ft	about 0.9 sq ft
80 lb	about 2.4 sq ft	about 1.8 sq ft	about 1.4 sq ft	about 1.2 sq ft

Pallet yield check

Planning pallet	Dry mix weight	Approx. yield
80 x 40 lb bags	about 3,200 lb	about 0.89 yd3
56 x 60 lb bags	about 3,360 lb	about 0.93 yd3
42 x 80 lb bags	about 3,360 lb	about 0.93 yd3
