Coil Yield by Profile at 99% target coil yield rate: a worked example

This scenario runs the coil yield by profile calculation on the strong side: 99% target coil yield rate, with every other input held at its documented default. Use it when coil yield by profile in roofing, siding and exterior building products needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Panels rejected for this profile: 8 count (unchanged)
  • Total panels formed for this profile: 250 count (unchanged)
  • Target coil yield rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Coil yield by profile rate = coil yield by profile count ÷ total coil yield by profile population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for coil yield by profile rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for coil yield by profile gap to target.
  • At this operating point the engine returns 8 count for coil yield by profile count.
  • At this operating point the engine returns 250 count for total coil yield by profile population.

How this compares with the baseline

  • Against the tool's baseline example, where target coil yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it per profile after a run or shift to rank which profiles scrap most and to feed a yield improvement backlog. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Coil yield by profile rate: 3.2 % (headline result)
  • Coil yield by profile gap to target: 95.8 points
  • Coil yield by profile count: 8 count
  • Total coil yield by profile population: 250 count

Run it with your numbers

  • Every input above is editable in the live Coil Yield by Profile calculator, which recalculates instantly and can be shared with the inputs intact.
