Concrete Mix Cost per Yard at 72% cost share assigned to this order or mix: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop cost share assigned to this order or mix to 72%, then walk the calculation through step by step. Estimate concrete mix cost for a ready-mix, precast, or concrete products order on a cubic-yard basis.

The inputs for this scenario

  • Concrete volume in the estimate: 1,200 cubic yards (held at the documented default)
  • Variable material and production cost per cubic yard: 92 $ / yd³ (held at the documented default)
  • Cost share assigned to this order or mix: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed batch setup, testing, delivery, or plant charge: 650 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Allocated concrete mix cost per yard = concrete volume in the estimate × variable material and production cost per cubic yard × allocation share.
  • Concrete Mix Cost per Yard works out to 80,138 $ mix cost at these inputs, and this is the headline figure for the scenario.
  • Variable material and production cost per cubic yard works out to 66.78 $ / piece at these inputs.
  • Allocated concrete mix cost per yard works out to 79,488 $ at these inputs.
  • Fixed batch setup, testing, delivery, or plant charge works out to 650 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cost share assigned to this order or mix sits at 100% and the headline result is 111,050 $ mix cost, this scenario comes in 27.84% below the baseline at 80,138 $ mix cost.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to cost share assigned to this order or mix, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single blended per-yard variable cost; if your mix changes strength class mid-job (e.g., 3,000 psi footings then 5,000 psi columns), run each design separately or your average will mislead.
