Steel Coil Cost at 58% share of coil charged to job: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop share of coil charged to job to 58%, then walk the calculation through step by step. Estimate the landed cost of a steel coil from coil weight, base price per hundredweight, the share of the coil charged to the job, and a fixed freight and processing adder.

The inputs for this scenario

  • Coil weight: 100 cwt (held at the documented default)
  • Steel base price: 45 $ / cwt (held at the documented default)
  • Share of coil charged to job: 58 % (the input this scenario stresses; the baseline uses 80)
  • Freight and processing adder: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Material cost = coil weight × steel base price × share of coil charged to job.
  • Total steel coil cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per cwt charged works out to 28.6 $ / piece at these inputs.
  • Material cost works out to 2,610 $ at these inputs.
  • Freight and processing adder works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of coil charged to job sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to share of coil charged to job, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses a single base price and a flat adder; volatile spot pricing, surcharges, and per-cwt freight that scales with weight are not modeled, so update the base price each quote.
