Wire Coil Yield at 71% target wire coil yield: a worked example

This worked example runs the wire coil yield numbers for a tougher week than the baseline: 71% target wire coil yield instead of the typical 98%. Calculate wire coil yield from usable fastener blank weight or count versus total coil issued, with a target yield comparison.

The inputs for this scenario

  • Usable wire converted to accepted output: 4,850 lb or pieces (held at the documented default)
  • Total wire issued from coil: 5,000 lb or pieces (held at the documented default)
  • Target wire coil yield: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Wire coil yield = usable output from coil รท total wire issued.
  • Wire coil yield works out to 97 % at these inputs, and this is the headline figure for the scenario.
  • Gap to coil-yield target works out to -26 points at these inputs.
  • Usable output works out to 4,850 lb or pieces at these inputs.
  • Wire issued works out to 5,000 lb or pieces at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target wire coil yield sits at 98% and the headline result is 97 %, this scenario lands almost exactly on the baseline at 97 %.
  • Use it per coil or per lot to monitor material utilization, validate cost-standard scrap allowances, and prioritize yield-loss investigations. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Wire coil yield: 97 % (headline result)
  • Gap to coil-yield target: -26 points
  • Usable output: 4,850 lb or pieces
  • Wire issued: 5,000 lb or pieces
